LED Wall Pixel Pitch Explained (and How to Pick It by Viewing Distance)
P1.5, P2.5, P3.9 — what the number means, and the simple rule for choosing it so you don't overpay or buy a fuzzy wall.
Pixel pitch is the one spec that most affects both how sharp your LED wall looks and what it costs — and it's the one buyers understand least. The good news: it's simple once you know what the number is and the rule of thumb for picking it.
- Pixel pitch = mm between LEDs; smaller number = sharper image and higher cost.
- Pick pitch by viewing distance — rule of thumb: min distance in meters ≈ pitch in mm.
- Fine pitch for up-close counters; coarser, cheaper pitch for backdrops seen across the aisle.
- If you're filming the wall, pitch and refresh rate both matter for a clean on-camera look.
What pixel pitch actually is
Pixel pitch is the distance in millimeters between the centers of two neighboring LEDs. “P2.5” means 2.5mm apart. Smaller number = LEDs packed closer together = a finer, sharper image — and more LEDs per tile, so a higher price per square foot. P1.5 is very fine; P3–P4 is coarser and cheaper.
The viewing-distance rule of thumb
You don't need the finest pitch — you need one that looks sharp at the distance people actually stand. A common rule of thumb: the minimum comfortable viewing distance in meters is roughly the pixel pitch in millimeters (so a P2.5 wall looks clean from about 2.5m / ~8ft and back). At a trade show, people view a wall from a few feet to across the aisle, so a fine pitch makes sense for content viewed up close at a counter, while a larger backdrop seen from across the aisle can use a coarser, more economical pitch.
Don't forget the camera
If your wall will be photographed or livestreamed, pitch and refresh rate both matter — a coarse pitch and a low refresh rate can show scan lines or moiré on camera even when the wall looks fine in person. Tell us if you're filming and we'll spec accordingly.

Frequently asked
Is a smaller pixel pitch always better?
No — it's sharper and more expensive, but past the distance people actually stand you can't see the extra detail. Match pitch to viewing distance instead of buying the finest available.
What pitch do I need for a booth?
It depends on how close attendees get. Up-close counter content wants a fine pitch (e.g. P1.5–P2.5); a backdrop viewed from across the aisle can use P3–P4 and save money.
