Single-Sided vs Double-Sided Drive Thru Menu Board: Which Layout for Your Project?

In the Drive Thru lane renovation project, the selection of single-sided and double-sided menu boards is often simplified as a hardware issue of "one more screen or one less screen". But from the perspective of B2B procurement, this is essentially a lane planning and operational efficiency decision: single-sided or double-sided directly determines lane traffic efficiency, unit area ordering capacity, civil construction volume, and subsequent maintenance costs. As a senior business manager at Clientop, I collaborate with dozens of global chain brands and integrators every year to complete the Drive Thr project selection. This article systematically outlines the selection logic of single and double-sided menu boards from dimensions such as lane layout, cost structure, installation complexity, heat dissipation, and waterproofing, helping buyers identify the most suitable solution in the early stages of the project.

1、 Single sided and double-sided are not simply about "having an extra screen" - why structural selection is important

Many project parties, when first encountering a drive thru menu board, tend to interpret the difference between single-sided and double-sided screens as' an additional display screen ', and only compare the number of screens and purchase price. This kind of cognition often leads to a series of chain problems in the later stage of the project: insufficient lane width causing installation difficulties, insufficient load-bearing capacity of the base causing safety hazards, poor double-sided heat dissipation shortening equipment life, and inadequate maintenance channel design leading to skyrocketing operation and maintenance costs.

In fact, single-sided and double-sided menu boards are two completely different structural systems. A single-sided menu board is a display unit facing in a single direction, with a simple structure, light weight, and clear heat dissipation path; A double-sided menu board is a system in which two screens are integrated back-to-back into the same housing or column structure, which requires solving a series of engineering problems such as double-sided board heating, center sealing, bidirectional waterproofing, and uniform load-bearing. Based on years of export project experience, the manufacturing base of Clientop has found that the BOM cost of double-sided menu boards is usually not twice that of single-sided panels, but about 1.6-1.8 times, because the reuse rate of structural components, heat dissipation systems, and waterproof designs is high, but the engineering difficulty is significantly increased.

There are four core judgment dimensions for selection: the first is lane layout - single lane or double lane, ordering lane or pickup lane; The second is the operational objective - to increase the demand for unit time throughput and average customer price; The third is project budget - one-time procurement cost, installation and civil engineering cost, long-term operation and maintenance cost; The fourth is the installation conditions - site width, base load-bearing capacity, and power supply capacity. These four dimensions comprehensively determine which side is more suitable for single-sided or double-sided display, rather than relying solely on intuition that "the larger the display area, the better.

2、 Single sided menu board: applicable scenarios and advantages and disadvantages

2.1 What is a single-sided drive-thru menu board

Single Sided Drive Thru Menu Board refer to outdoor digital signage that display\ menu content only in one direction, and is the most basic and widely used display form in Drive Thru lanes. It usually consists of a high brightness LCD panel, IP65 waterproof housing, heat dissipation system, and column base. The screen faces the direction of the vehicle, and the driver can clearly read the menu content at the ordering position.

At present, the mainstream single-sided menu board sizes in the industry are concentrated in three specifications: 43 inches, 49 inches, and 55 inches. Among them, the 43inch drive thru menu board for commercial projects is suitable for small single lane stores and limited space scenarios; The 49inch drive thru menu board for QSR chains is the most popular intermediate specification, balancing visual area and footprint; 55inch drive-thru menu board for franchise restaurants It is suitable for high traffic standard lanes and can display richer menu zones and promotional content. In terms of brightness, outdoor Drive Thru scenarios generally require 2500 nits or more, with a minimum IP protection level of IP65, and a working temperature coverage of -30 ° C to 70 ° C to meet deployment need in different climate region around the world.

2.2 The core advantages of single-sided menu board

The cost is controllable and the procurement threshold is low. The single-sided menu board has a simple structure, clear material list, and short production cycle. For budget limited first store projects or regional pilot projects, the equipment investment for single-sided solutions is only about 55% -65% of that for double-sided solutions, which can effectively reduce the initial investment pressure. Client's standard single-sided models are all in stock and can be delivered within 3-7 days, making them particularly suitable for renovation projects with tight schedule.

Easy installation and low civil engineering requirements. The single-sided menu board is relatively lightweight (about 80-120kg for 49inch models), with low difficulty in base construction and column construction, and can be supported by a single column. When digitizing existing lanes, single-sided solutions can usually utilize the existing lightbox base for renovation, significantly reducing on-site construction and downtime.

Clear heat dissipation path and higher reliability. The heat sources (screen body, power supply, motherboard) of the single-sided menu board are concentrated on the same side, and the back can fully utilize natural convection heat dissipation. Under the same brightness specifications, the internal operating temperature of single-sided models is 5-8 ° C lower than that of double-sided models, the fan start stop frequency is lower, theoretically the service life is longer, and the failure rate is lower. This is particularly crucial in projects in high-temperature and desert climate region

Easy maintenance and low subsequent operation and maintenance cost. The back cover opening and module replacement of the single-sided menu board only involve single-sided operation, and on-site maintenance personnel can quickly complete the replacement of components such as the screen body, power supply, and fan. From the perspective of full lifecycle cost, the annual maintenance cost of the single-sided solution is about 3% -5% of the equipment purchase price, significantly lower than that of the double-sided solution.

2.3 Limitations of Single sided Menu Board

The core limitation of a single-sided menu board is that the display surface has only one direction. If it is a layout where two lanes share a ordering island, the single-sided solution requires setting up two independent menu boards facing towards each lane, which will actually increase the number of equipment and total cost. In addition, the single-sided solution cannot utilize the back for pre sell display or brand promotion, and the information carrying capacity of the lane is relatively limited.

Another easily overlooked limitation is lane throughput. A single-sided menu board can only serve the ordering needs of one lane. If the store has a long queue during peak hours, the bottleneck of a single-sided menu board on a single lane will be more obvious. For peak stores with an average daily order volume exceeding 300 orders, relying solely on a single-sided menu board may not be able to support ordering efficiency, and it is usually necessary to cooperate with pre-sale boards or switch to double-sided/dual screen solution.

3、 Double sided menu board: applicable scenarios and advantages and disadvantages

3.1 What is a double-sided drive-thru menu board

Double Sided Drive Thru Menu Board is an outdoor digital menu system that installs a display screen on both sides of the same housing or column structure, and can display content in two opposite directions simultaneously. Two screens can play the same content or independently control and play different content, depending on the lane layout and operational strategy of the project.

The core value of a double-sided menu board lies in "one structure, two-way display". In a dual lane layout, a double-sided menu board can simultaneously serve the left and right ordering lanes, which is equivalent to achieving the function of two single-sided menu boards with a set of structural costs. For scenarios where lane space is limited and two independent single-sided menu boards cannot be installed side by side, the double-sided solution is almost the only choice. The double-sided model of Client op adopts an integrated die cast aluminum backplate structure, ensuring the installation flatness and thermal conductivity efficiency of the two screens, which is also a direct reflection of the mold capability of the manufacturing base.

3.2 The core advantages of double-sided menu boards

Dual lane sharing results in better unit lane costs. In a two lanes layout, a double-sided menu board can replace two single-sided menu boards. Although the single unit price of double-sided models is higher than that of single-sided models, it is lower than the total price of two single-sided models (about 1.6-1.8 times the single unit price), and only requires one set of base, one set of wiring, and one set of construction. Based on comprehensive calculations, adopting a dual carriageway scheme saves approximately 20% -30% of the total cost of ownership (TCO) compared to using two single-sided schemes.

One front and one back, with dual functions of ordering and pre selling. The flexible use of double-sided menu boards goes far beyond dual lane sharing. In a single lane scenario, a double-sided menu board can also be installed in the middle of the lane: one side facing the direction of oncoming traffic serves as a Preell Board, displaying promotions and recommended dishes in advance, allowing customers to make decisions while queuing; The other side faces the ordering area as the official menu board. This combination of front and back content has been proven by industry data to increase the average order price by 10% -15%, while reducing ordering time by about 15% -25%.

Save space on the site and make the lane layout more flexible. The double-sided menu board only requires one installation position, which can save valuable horizontal space for stores with limited lane width and narrow ordering island space. Especially in the Drive Thru stores in the city center, the space is usually cramped, and the dual sided menu board's "all-in-one dual-use" feature can make lane planning more relaxed.

Double the brand display area, with a stronger visual impact. From the perspective of brand image, both sides of the double-sided menu board can display the brand VI, and customers can see a unified brand visual no matter which direction they approach the store from. For chain brands that value brand image, double-sided menu boards are not only ordering tools, but also outdoor brand touchpoints. The double-sided model of the Client op supports full body customized spray painting and brand color matching, meeting the VI consistency requirements of global chain brands.

3.3 The Challenge of Double sided Menu Board

The difficulty of heat dissipation design is high, and internal temperature control is the key. The double-sided menu board work back-to-back with two screens, and the heat is concentrated in the middle cavity. If the heat dissipation design is not in place, the internal temperature will rise sharply, directly affecting the lifespan and stability of the screen body. Some low-priced double-sided products in the industry often experience issues such as black screens and accelerated brightness decay in high temperature environments during summer due to their simple heat dissipation design. The double-sided model of the Client op adopts bidirectional independent air ducts and intelligent temperature control system. Each screen has an independent air inlet and outlet path, ensuring that the working temperature of the two screens is balanced. This is also the result of years of mold and structural design experience accumulated by the manufacturing base.

Larger weight, higher requirements for base and installation. The weight of the double-sided menu board is about 1.6-2 times that of the single-sided models of the same size (49 inch double-sided compared to 49inch single-sided), which puts higher requirements on the base load-bearing, column bending resistance, and wind load design. Installing a double-sided menu panel requires a more sturdy concrete base and thicker columns, resulting in a corresponding increase of approximately 30% -50% in civil engineering costs. In existing lane renovation projects, it is also necessary to evaluate whether the original base can withstand the weight and wind load of double-sided models, and reinforcement treatment may be necessary if necessary.

Both sides need to be waterproof and sealed, with high process requirements. A single-sided menu board only needs to ensure that the front is waterproof, and the back has a back cover and heat dissipation holes; The double-sided menu board requires IP65 protection level on both sides, and the structural seams, threading holes, and border connections in the middle need to be waterproofed, significantly increasing the complexity of the process. If the sealing process is not up to standard, rainwater or moisture may seep into the joints, causing internal circuit short circuits or screen moisture.

The maintenance complexity is higher. The internal structure of a double-sided menu board is more complex, with two screens sharing the heat dissipation and power supply system in the middle. During maintenance, both sides need to be considered for disassembly and assembly. The technical requirements for on-site maintenance personnel are higher, and the maintenance time is also longer. Therefore, the double-sided solution is more suitable for integrators or brand owned operation and maintenance teams with certain technical capabilities.

4、 How to choose lane layout: ordering lane/pickup lane/two-way lane

4.1 Layout of single order food lane

The bicycle lane is the most common Drive Thru layout, especially suitable for small and medium-sized stores and scenes with a daily order volume of 200 or less. In the single order lane, the menu board is installed on the right side (left-hand drive country) or left side (right-hand drive country) of the ordering position, and the driver can directly face the menu board to order after parking.

Selection suggestion: In a single lane scenario, if the lane space is sufficient and the budget allows, we recommend a combination of "single-sided main menu board + single-sided pre-sale board" - the main menu board displays the complete menu at the ordering position, and the pre-sale board displays promotions and recommended dishes upstream of the lane. The combination of the two can significantly improve ordering efficiency and customer price. If the budget is limited or space is tight, a single-sided main menu board can also meet basic needs. It is not recommended to use double-sided menu boards in bicycle lanes, as the screens on the back will be wasted (facing towards the outside of the lane or lawn, without spectators)

Regarding size selection, single lane stores can choose based on daily order volume and menu complexity: small stores with less than 100 orders per day and fewer SKUs (such as Coffee Drive Thru and Pharmacy Drive Thru) can choose a 43 inch commercial drive thru menu display; A standard fast food restaurant with a daily order volume of 100-250, 49 inches is the most balanced choice; For large stores with a daily order volume of 250 or more and a large number of menu SKUs, it is recommended to consider a 55 inch outdoor drive thru menu screen or even a dual screen splicing solution. If you are not familiar with what is a Digital Drive Thru Menu Board, you can first read our definition article "What is a Digital Drive Thru Menu Board?" for a basic understanding.

4.2 Layout of dual lane shared dining island

The dual lane layout is a standard configuration for high traffic stores, which increases the throughput per unit time through two parallel ordering lanes. There is a shared ordering island between two lanes, and the menu board is installed on the ordering island, facing drivers from both lanes at the same time.

Selection suggestion: The dual lane shared ordering island is the most classic application scenario for double-sided menu boards. A double-sided menu board is installed in the center of the ordering island, facing the left and right lanes on both sides. Drivers can clearly see the menu content from their respective lanes. Compared to installing two independent single-sided menu boards, the double-sided solution only requires one base, one set of wiring, and one construction, with lower overall cost and simpler installation.

It should be noted that the dual lane double-sided plan requires the ordering island to have sufficient width to install the pillars of the double-sided menu board, and the parking positions of vehicles on both lanes need to be precisely designed to ensure that drivers on both sides are at the optimal viewing distance and angle. Clientop has complete lane layout simulation capabilities at the manufacturing base, which can verify the viewing angle and distance based on the lane plan provided by the customer, ensuring that the double-sided menu board has the best display effect on both sides. In addition, the content of the two screens can be independently controlled - the left and right lanes can display the same complete menu, and different promotional content can also be displayed according to operational strategies.

4.3 Pickup Lane layout

The pick-up lane is the final stage of the Drive Thru process, where customers collect their food at the pick-up window. The display requirements of the pick-up lane are different from those of the ordering lane: the display screen of the pick-up slot is mainly used for order confirmation, displaying customers' order details, allowing customers to check the order content before picking up, reducing errors and complaint.

Selection suggestion: The order confirmation screen for the dining lane is usually single-sided, as it only needs to be displayed facing the driver's side inside the car. The screen size can be smaller than the ordering menu board, with 32 inches or 43 inches meeting the requirements. If it is a two lane dining window with back-to-back layout, a double-sided solution can be considered, using a double-sided screen to simultaneously serve two dining lanes.

4.4 Layout of two-way lanes/back-to-back lanes

In some special site planning, a two-way lane layout may appear - two lanes in opposite directions, back-to-back sharing the equipment island in the middle. This layout is common in stores with narrow spaces or in scenarios where vehicles need to be serviced in both directions simultaneously.

Selection suggestion: Two way lanes are another typical application scenario for double-sided menu boards. A double-sided menu board is installed on the central equipment island, with two lanes facing in opposite directions on both sides. Drivers in each lane can see the menu content facing them. Under this layout, the economic and spatial advantages of the double-sided menu board are particularly prominent - compared to two independent single-sided menu boards, the double-sided solution saves one base, one set of civil engineering, and half of the installation space。

5、 Cost comparison: procurement cost/installation cost/maintenance cost

Purchasing decisions cannot be solely based on equipment unit prices, but need to be comprehensively evaluated from the perspective of Total Cost of Ownership (TCO). The following is a cost comparison of single and double-sided menu boards from three dimensions. The data is based on historical project data from the Clientop manufacturing base and industry average levels. Specific project quotations may vary depending on specifications, quantities, customization requirements, and transportation condition.

Purchasing cost: The purchasing unit price of double-sided menu boards is higher than that of single-sided ones, but less than twice that of single-sided ones. This is because the double-sided model shares most of the structural components, power system, and housing molds, and the incremental cost of the second screen is mainly due to the screen body itself and additional heat dissipation components, rather than replicating a complete set of equipment. For a two lane project, the price of one double-sided panel is significantly lower than the total price of two independent single panels, which is the core cost advantage of the double-sided solution.

Installation cost: The installation cost of a double-sided menu board is higher than that of a single-sided one, mainly due to three aspects: the base needs to be larger and heavier, equipment lifting requires more manpower and equipment, and double-sided debugging needs to verify the display effect on both sides. But in the dual lane scenario, the double-sided scheme only needs to be installed once, while the two single-sided schemes need to be installed twice. Overall, the installation cost of the double-sided scheme is still lower.

Maintenance cost: The annual maintenance cost of double-sided menu boards is relatively high because the structure is more complex, there are more components, and both sides require regular cleaning and inspection. However, from the perspective of 5-year TCO, if a dual carriageway adopts a double-sided solution, the overall maintenance cost is still lower than the sum of the maintenance costs of two single panels. More importantly, choosing a supplier like Clientop with mature manufacturing capabilities, whose products undergo 48 hours of aging testing and full functional testing before leaving the factory, with a failure rate of less than 0.5% in the first year, can effectively reduce maintenance costs in the later stage.

Regarding the complete cost analysis and budget composition of the Drive Thru menu board, we will have a dedicated article to break it down in detail, including methods for calculating equipment costs, installation costs, software expenses, operation and maintenance costs, and investment return cycle.

6、 Differences in structural design: heat dissipation/weight/waterproofing

6.1 Differences in heat dissipation design

Heat dissipation is one of the core reliability indicators of outdoor digital signage, which directly determines the service life and stability of the equipment. The heat dissipation design of a single-sided menu board is relatively simple: the screen body heats up on the front, and the heat is discharged to the back through the heat dissipation fins or fans on the back panel. The back panel can be perforated for air intake, and air enters from the back and exits in the front direction, forming a clear one-way airflow.

The heat dissipation of a double-sided menu board is much more complex. Two screens work back-to-back, and heat accumulates in the middle. If not specially designed, the central area will form a heat island effect, leading to high internal temperatures. There are several common double-sided heat dissipation solutions in the industry: one is a shared heat dissipation chamber +bidirectional fan, where the heat from both screens is discharged to the middle chamber, and then convective discharge is formed by the top and bottom fans; The second is independent air duct design, with each screen having independent air inlet and outlet paths that do not interfere with each other; The third is heat pipe +aluminum substrate conduction heat dissipation, which transfers heat to the base or shell through the heat pipe and dissipates it.

The double-sided menu board of the Client op adopts a solution of independent air ducts and intelligent temperature control. Each screen has its own independent air inlet and outlet, and air enters from the bottom and exits from the top, forming two parallel heat dissipation channels. Combined with PWM intelligent speed control fan, the speed is automatically adjusted according to the internal temperature, reducing noise and energy consumption while ensuring heat dissipation effect. This design scheme has been validated through years of mold iteration and thermal simulation in the manufacturing base. When working continuously at an ambient temperature of 45 ° C, the maximum temperature difference inside the double-sided screen does not exceed 3 ° C, ensuring that the brightness decay rate of the two screens is consistent and there will be no situation where one side is bright and the other is dark.

6.2 Difference in weight and structural strength

Weight is a key parameter that affects the installation plan and base design. Taking the 49inch model as an example, the overall weight of a standard single-sided menu board is about 80-120kg, while the double-sided model weighs about 140-200kg, almost 1.6-1.8 times that of a single-sided one. The increase in weight is not only due to the addition of an extra screen, but also includes a thicker structural frame, stronger columns, additional heat dissipation components, and double-sided sealing structure.

In terms of structural strength, double-sided menu boards have higher requirements：Firstly, flexural strength - double-sided screens have a higher center of gravity and a larger wind area, requiring stronger wind resistance and load-bearing capacity; Secondly, torsional stiffness - the weight of the two screens is symmetrically distributed. If the structural rigidity is insufficient, it is prone to torsional deformation under strong winds, which affects the sealing performance; Thirdly, base anchoring - double-sided models require deeper and larger concrete bases with more anchoring bolts. The double-sided menu panel of the Client op adopts an integrated die cast aluminum middle frame and galvanized steel plate back panel structure, with uniform weight distribution and structural rigidity verified by wind tunnel simulation. It can withstand wind loads of level 12 typhoons (wind speeds above 32.7m/s).

6.3 Differences in Waterproof and Sealing Design

Waterproof rating is one of the core indicators of the Drive Thru menu board. In outdoor environments, rainwater, moisture, and direct spraying from car wash water guns can test the waterproof ability of equipment. The industry standard is IP65 for the front, which means it is completely dust-proof and can withstand low-pressure water jet; Higher specification products can achieve IP66 and withstand high-pressure water jet.

The waterproof design of the single-sided menu board is relatively direct - the front glass and frame are sealed with adhesive tape, and the back is protected by a back cover and waterproof joint. Because there are heat dissipation holes and fans on the back, the protection level of the back is usually slightly lower than that of the front (IP54 or IP55). When installed, the back is usually facing the inside of the building or canopy to reduce direct exposure to rain.

The waterproof challenge of double-sided menu boards is that both sides need to reach IP65 protection level. The front side is easy to handle and sealed with glass tape just like the single-sided one; The difficulty lies in the side seams, the threading holes and heat dissipation ports at the top and bottom, and the connection structure between the two screens. Any inadequate sealing can become a leak point. The double-sided model of the Client op adopts a full perimeter waterproof tape and labyrinth drainage structure design, with a rainproof brim at the top and drainage holes at the bottom. Even if a small amount of water vapor enters, it can be discharged by gravity and will not accumulate inside. Each double-sided equipment in the manufacturing base undergoes rain testing and high-pressure water gun testing before leaving the factory to ensure that the waterproof performance meets the standard.

For a detailed interpretation of core specifications such as brightness and IP rating, you can refer to our technical comparison article "LCD vs LED Drive Thru Menu Board" and specification selection guide, which provide more systematic parameter explanations.

7、 Quick selection decision framework

Based on the above analysis, we have summarized a quick decision-making framework that helps project leaders determine which direction is more suitable for both sides during the initial contact stage. This is a third-order judgment method that filters layer by layer starting from the core constraint conditions.

Typical application scenarios of single-sided menu boards: small single lane stores, first store pilot projects with limited budgets, projects with extremely high reliability requirements in extreme high temperature areas, remote area stores with limited maintenance capabilities, and scenarios where double-sided equipment cannot be installed due to narrow lane spaces.

Typical application scenarios of double-sided menu boards: dual lane high traffic stores, dual lane layouts, stores that require dual functions of pre-sales and ordering, chain standard stores that value brand image, and scenes where there is an equipment island available in the center of the lane.

If you are still unsure which option to choose, the safest approach is to provide a lane plan and basic project information, and have the manufacturer's technical support team evaluate the plan. The technical team of Clientop has extensive global project experience and can recommend the most suitable single-sided and double-sided configurations and screen sizes based on parameters such as lane layout, traffic flow, and menu SKU quantity. In addition, our manufacturing base supports OEM/ODM customization, including customized development of size, appearance, structure, and functional modules, which can meet the needs of various special projects.

8、FAQ

Q1：Do dual sided menu boards have to be used for dual carriageways? Can we use two single-sided ones instead？

Not necessarily. Two lanes can be equipped with two independent single-sided menu boards installed on the outside of each lane, or a double-sided menu board can be installed on the ordering island in the center of the lane. Which option is better depends on the lane layout: if there is enough space between two lanes to set up a central ordering island, the double-sided option is more economical (saving about 20% -30% TCO) and simpler; If the distance between two lanes is large, or if there is a building/green belt in the middle that cannot have a central island, only two single-sided schemes can be used for installation. From the display effect, there is not much difference between the two schemes. The key is to ensure that the driver has the best viewing distance and angle at the ordering position.

Q2：Can two screens on a double-sided menu board play different content？

Okay. The double-sided menu board has two control modes: same display mode (two screens display the same content) and different display mode (two screens play different content independently). The same display mode is suitable for symmetrical dual lane layouts, where both lanes display the same menu; The cross display mode allows two sides to play different content separately, such as a complete menu on one side, promotional recommendations on the other side, or two lanes displaying different limited time offers. The abnormal display mode requires dual motherboards or dual signal inputs, and the requirements need to be explained in advance when purchasing. The dual sided model of Client op supports both same display and different display modes, which can be switched through software. The project team can flexibly adjust according to operational need.

Q3：Is the failure rate of double-sided menu boards higher than single-sided ones? Shorter service life？

In theory, the double-sided menu board has more components (two screens, two sets of backlighting, dual fan system), and indeed more fault points. But the actual failure rate depends on the manufacturer's design and manufacturing level. If the heat dissipation design is reasonable, the component selection is high-quality, and the factory inspection is strict, the reliability of the double-sided menu board can be close to that of single-sided. According to industry data, the first-year failure rate of high-quality double-sided models is about 0.8% -1.2%, while single-sided models are about 0.3% -0.5%, and the difference is within a controllable range. In terms of service life, if the temperature is properly controlled, the screen life of double-sided models is equivalent to that of single-sided models (more than 50000 hours). The key is to ensure that the working temperature of the two screens is balanced and avoid uneven brightness attenuation caused by overheating on one side.

Q4：Can a single-sided menu board be later modified to double-sided？

Basically not possible. The structure, heat dissipation, power supply, and base of a single-sided menu board are designed to be single-sided, and it is not possible to simply add a screen on the back to make it double-sided. Double sided structures that require specialized back-to-back design, bidirectional heat dissipation, double-sided waterproof sealing, and reinforced bases are all determined during the product design phase and are almost impossible to modify on site. If it is uncertain in the early stages of the project whether double-sided machines will be needed in the future, it is recommended to reserve the load-bearing capacity and pipeline allowance for double-sided models during the foundation construction phase, and replace the entire machine directly in the later stage, rather than attempting to modify it. During the project planning phase, the manufacturing base of Clientop can provide clients with phased implementation suggestions. Firstly, the single-sided verification effect should be carried out, and later, the decision to upgrade to a double-sided solution should be made based on operational data.

Q5：How to choose 43/49/55 inches? Is there a relationship between size and single-sided or double-sided？

The size selection mainly depends on the viewing distance, the number of menu SKUs, and the lane width, and has no direct binding relationship with single-sided and double-sided surfaces. Generally speaking, the farther the viewing distance and the more menu content, the larger the required screen size. Industry experience is to choose 43 inches for viewing distances of 3-5 meters (small lanes), 49 inches for viewing distances of 5-7 meters (standard lanes), and 55 inches for viewing distances of 7 meters or more or menu SKUs exceeding 50. The double-sided menu board also follows this principle - the viewing distance between both sides determines the required size specifications. It should be noted that large-sized double-sided models have greater weight and wind load, and higher requirements for the base. The weight of a 55 inch double-sided machine can reach over 200kg, which will significantly increase the cost of civil engineering.
