What is “pixel pitch”?
The pixel pitch is the distance between two adjacent LED pixels, measured centre to centre, in millimetres. A wall with pitch P2.5 therefore has 2.5 mm between pixels – one with P10 has 10 mm. The smaller the value, the finer the image and the closer the viewer can approach without perceiving individual pixels.
Which pitch for which purpose?
- P1.2 – P1.9: conference rooms, studios, control rooms – viewing distance from approx. 1.5 m.
- P2.5 – P2.9: premium indoor walls, lobby, showroom – from approx. 3 m.
- P3.9 – P4.8: rental, stage, large events – from approx. 4–5 m.
- P6 – P10: outdoor, façade, stadium – from approx. 7–15 m. Here, brightness and weather resistance matter more than fine pixels.
Rule of thumb: pitch × 1 m = minimum viewing distance
A quick rule of thumb: the pixel pitch in millimetres roughly corresponds to the minimum viewing distance in metres. For P5, that is around 5 m; for P3, around 3 m. If you want to get closer, choose a finer pitch – if viewers tend to look from further away, a coarser pitch can save a great deal of money without the image appearing “coarse”.
