What size screen do I need for digital signage?
Viewing distance rule
A simple guideline is that text should be at least 1 inch tall for every 10 feet of viewing distance. For a screen, this translates to roughly 1 inch of screen height per 6-10 feet of distance, depending on content.
For a restaurant menu board viewed from 5-10 feet away, a 43-55 inch screen is often sufficient. For a large lobby or window display viewed from 20 feet or more, you may need a 65-75 inch screen or larger.
Content and orientation
Text-heavy menus need larger screens or fewer items per screen. Video and images can work on smaller screens because they don't require reading fine detail.
Portrait orientation is popular for menu boards because it mimics a printed menu and allows for more vertical items. Landscape works better for wide graphics or multiple columns.
- Counter menu: 32-43 inch
- Drive-thru or behind-counter: 43-55 inch
- Lobby or window display: 55-75 inch
- Large venue or far viewing: 75 inch and up
Resolution and aspect ratio
Full HD (1920x1080) is standard for most signage. 4K (3840x2160) is useful for very large screens or close viewing, but it costs more and requires more powerful media players.
Most commercial displays are 16:9. Some ultra-wide or stretched displays are available for specific applications like transportation or shelf-edge signage.
Common mistakes
- Choosing a screen size based on price rather than viewing distance.
- Using a small screen for a menu with too many items, making text hard to read.
- Ignoring orientation—portrait vs. landscape—which affects how content fits.
