01
Choose a direct-view LED pixel pitch from the closest viewing distance, then resolve the cabinet grid, native resolution, power, weight and data port count for the wall.
02
Tip. Retinal pitch is set by the closest viewer, not the average one. Anyone who can walk up to the wall sets the requirement, so a lobby display people pass within a metre of needs a far finer pitch than its viewing distance on the drawing suggests.

Pixel pitch and viewing distance

Pixel pitch is the distance between the centres of adjacent LEDs, and it sets the closest anyone can stand before the image stops being an image and becomes a grid of dots. Finer pitch means more pixels, more cabinets’ worth of electronics, more power and considerably more cost, so the pitch is chosen by the nearest viewer rather than the typical one.

Retinal pitch

The pitch at which adjacent pixels subtend one arc-minute at the closest viewer — the limit of human visual acuity, and the point at which the pixel structure stops being resolvable.

Use cases

≤ 1.2 mm — broadcast and studio backdrops
≤ 2.0 mm — corporate lobbies and boardrooms
≤ 3.0 mm — retail and public spaces
≤ 6.0 mm — venues, arenas and long throws

Formula

Pitch (mm) = viewing distance (m) × 1000 ÷ 3438

3438 arc-minutes per radian

Array build-up

Cabinets set the physical grid; pitch sets the native resolution inside it. Both power and data ports scale with total pixel count, and both are usually specified late and found short.

Use cases

Cabinet grid rounds up to whole cabinets
Native resolution = cabinet pixels × grid
Average power is typically 30–40 % of peak
Roughly 650k pixels per gigabit data port

Formula

Native pixels = (cabinet width ÷ pitch) × cabinets across

Confirm against the vendor datasheet

The "10× rule" — minimum comfortable viewing distance in metres equals pitch in millimetres — is a sales heuristic, not a standard. It is close to the arc-minute result by coincidence over the common pitch range and diverges outside it. This tool reports it as an assumption alongside the acuity figure.
