How big the wall really is on the fixing, and how fine its pixels are — the numbers the installer and the room need.

How far away people can stand: too close and the pixels show, too far and the detail is lost.

Design guideA full-size guide to hand your designer

A guide at exactly 1920 × 1080 px: each screen numbered with its position, the strips the bezels hide hatched, the 5 % graphics-safe area dashed, and the centre marked. Put it on a layer above your artwork.

Where the answers come from

The bezel gaps come from the same formula castv.ai uses to cut each screen's tile on the server: both neighbours' bezels, converted at each screen's pixel pitch, averaged and rounded to an even number of pixels. Viewing distances use the LED industry's 1 m per mm of pitch, one arcminute of 20/20 vision, a 40° field of view and AVIXA's 4/6/8 rule.
