How to Calculate Screen Size for Restaurants and Cafes

Restaurants and cafes today are more than just places to eat or grab a quick coffee. They are social hubs where people come together to relax, meet friends, watch live sports, or even work remotely. In this atmosphere, digital screens play an important role. From displaying menus and promotions to creating an entertainment experience for customers, the right screen can transform the vibe of a space. However, choosing the correct screen size is not as straightforward as it might seem. Too small, and it will fail to grab attention. Too large, and it can feel overwhelming in a cozy space. This is where calculating screen size effectively comes in.

Why Screen Size Matters in Restaurants and Cafes

The size of the screen directly influences the customer experience. In restaurants, a well-placed screen showing a live sports match can keep customers engaged longer, increasing their likelihood of ordering more food and drinks. In cafes, digital menu boards with clear visibility make ordering simpler. A properly chosen screen size ensures clarity of information, reduces eye strain, and adds to the overall ambiance. If the screen is too large for the seating arrangement, it may distract diners rather than enhance their visit.

Key Factors to Consider When Calculating Screen Size

1. Viewing Distance
   The first step in determining the right screen size is understanding the average viewing distance. For example, in a café where people are sitting at small tables, the distance to the screen may only be a few feet. In a restaurant with larger dining areas, the distance could be much greater. A general rule of thumb is that the ideal viewing distance is 1.5 to 3 times the diagonal screen size.

2. Room Dimensions
   Restaurants and cafes vary in shape and layout. A narrow café with limited wall space requires smaller displays compared to a large sports bar with high ceilings and wide walls. The room’s proportions should always guide the screen size choice.

3. Content Type
   The purpose of the screen also affects size. A digital menu board needs to be large enough so customers can easily read text from the ordering counter. For sports bars, the screen size should provide clear visuals from multiple seating positions across the room. Background content like ambience videos or branding can usually be shown on smaller or secondary screens.

4. Multiple Screens vs One Large Screen
   In many cafes and restaurants, using multiple medium-sized screens spread across the space works better than relying on a single large screen. This ensures that every customer has a clear view without straining their necks or turning their chairs.

Step-by-Step Guide to Calculating Screen Size

Step 1: Measure Viewing Distance
Start by noting the average distance from where customers sit to the planned screen placement. For instance, if customers are typically seated about 10 feet away, then a screen of around 55 to 70 inches might be suitable.

Step 2: Apply the Viewing Ratio Rule
Use the 1.5 to 3 times diagonal size rule. If the screen diagonal is 60 inches, then the optimal viewing distance should be between 7.5 and 15 feet. This helps balance clarity and comfort.

Step 3: Match Screen Purpose with Size
If the screen is primarily for menus, smaller displays may suffice. If it is for entertainment such as sports or movies, a larger display is ideal. For example, a café menu board may need a 43-inch display, while a sports bar might need a 75-inch or larger screen.

Step 4: Consider Brightness and Resolution
In restaurants and cafes, lighting can impact visibility. A brighter screen with high resolution can allow you to choose slightly smaller sizes without losing clarity. For example, a 4K 55-inch screen might perform as effectively as a 65-inch HD display.

Practical Examples

1. Café with Limited Space
   Imagine a small café where the average viewing distance is 8 feet. A 43 to 50 inch screen would be perfect for menu display and light entertainment content.

2. Medium-Sized Restaurant
   In a restaurant where seating is spread across 15 feet of space, a 65-inch to 75-inch screen ensures everyone can see comfortably. For sports nights, multiple 55-inch screens around the dining space can also work well.

3. Sports Bar
   A sports bar with long seating distances of 20 feet or more requires very large screens of 85 inches or even multiple projectors to ensure all guests have a great view.

Balancing Design and Technology

While calculations are important, screen size must also blend with the restaurant or café’s interior design. A screen that dominates the décor may feel out of place in a cozy coffee shop but could be perfect for a high-energy sports bar. Placement at the right height is equally critical. Screens should be mounted at eye level for seated customers whenever possible.

Using Tools to Simplify Calculations

Platforms like XTEN-AV provide advanced tools that help in calculating and designing AV setups for restaurants and cafes. These tools take into account factors such as viewing distance, screen resolution, and room layout, allowing you to get accurate recommendations for the best screen sizes. With such solutions, owners and designers can ensure that technology enhances the customer experience without guesswork.

Conclusion

The right screen size in a restaurant or café is not a random choice. It is a balance of viewing distance, room dimensions, content type, and customer comfort. A well-calculated screen size improves engagement, keeps customers comfortable, and contributes to the overall atmosphere. By considering the factors outlined above and using professional AV design tools like XTEN-AV, you can make the best decisions for your space. Whether it is a small café with a digital menu board or a large sports bar with multiple displays, the right screen size calculation is key to creating the perfect environment for your customers.
