Quick answer

  • Our range covers 21.5–86 inch; 43–55 inch is a common starting range for retail, menu boards and lobbies.
  • For text-heavy content, test the layout at the real distance; a practical starting point is 1.5–2× the screen height.
  • Indoor panels are typically 250–700 cd/m²; window and outdoor positions may need 1,500–3,500 cd/m².
  • Portrait or landscape is a software setting, but panel orientation, bracket and safe area must be confirmed per model.

Start with viewing distance

A screen that is readable in a meeting room may be unreadable across a mall concourse. Measure the typical distance first, then decide how much text must be legible there.

  • 1–2 m: counter, meeting room, small menu board; 21.5–43 inch is often enough.
  • 2–4 m: retail aisle, restaurant menu, lobby; 43–55 inch is the usual starting range.
  • 4–8 m: large lobby, window, auditorium entrance; 65–86 inch is easier to read.
  • Use the 1.5–2× screen-height starting point for text-heavy layouts, then test the real artwork.

Frequently asked questions

Questions buyers ask about this decision

What size for a 3 m viewing distance?

For text-heavy menus or retail messages, 43–55 inch is a common starting range at 3 m, but test the artwork at the actual distance. If text is small, move up a size or simplify the layout.

Is 4K necessary?

Not automatically. At typical signage distances, 1920×1080 is common on 43–55 inch screens. 4K is more useful for close viewing, large formats or detailed dashboards. Confirm player output and content canvas.

Can the screen be mounted vertically?

Portrait support is model-specific. Confirm the panel orientation, bracket and content safe area for the exact model before ordering.

What brightness for a shop window?

A shaded wall may work at 500–700 cd/m²; a sunlit window may need 1,500–3,500 cd/m² and a high-bright panel. Measure the window at midday.
