LED pixel pitch, explained in plain English.
Pitch is the one spec that decides how sharp your screen looks — and how much it costs. Here's how to read it, and how to pick the right number without overpaying.
LED pixel pitch is the distance in millimetres between the centre of one LED and the next — a P2.5 screen has 2.5 mm spacing, a P10 has 10 mm. Smaller pitch means higher resolution and a closer sharp-viewing distance, at higher cost per square metre. To choose the right pitch, match it to your closest viewing distance: the minimum comfortable distance in metres is roughly the pitch number, so P10 suits billboards seen from 10 m or more, P2.5 suits retail seen from 2–8 m, and P1.5 suits camera-facing launch walls viewed up close.
If you've asked anyone for an LED screen quote, you've seen the codes: P1.5, P2.5, P3.9, P10. That "P" number is the pixel pitch — the single most important spec on the page. Get it right and the screen looks crisp for every viewer at the cost it should. Get it wrong and you either see the pixels or you pay double for resolution nobody can see.
What pixel pitch actually means
Pixel pitch is the distance, in millimetres, between the centre of one LED and the centre of the next. A P2.5 screen has 2.5 mm between pixels. A P10 screen has 10 mm. That's the whole definition.
Smaller pitch packs more pixels into the same square metre, so the image is higher-resolution and stays sharp closer up. It also costs more — more LEDs, more driver electronics, more labour per panel. A P1.5 wall can carry roughly 444,000 pixels per square metre; a P10 carries about 10,000. That gap is the whole price story.
The one rule that matters: match pitch to viewing distance
Your eye can't resolve individual pixels past a certain distance. Beyond that point, extra resolution is money spent on detail no one will ever see. So the goal isn't the smallest pitch — it's the largest pitch that still looks sharp from where people actually stand.
The rough rule installers use: the minimum comfortable viewing distance, in metres, is close to the pitch number itself. A P10 screen looks clean from about 10 m back. A P3 looks clean from about 3 m. Closer than that and the grid starts to show; much further and you're overpaying.

Pitch by environment — a cheat sheet
| Pitch | Looks sharp from | Best for |
|---|---|---|
| P1.5 | ~1.5 m | Camera-facing product-launch walls, broadcast, fine-detail close-up |
| P1.8–P2.5 | 2–8 m | Mall storefronts, lift-lobby pylons, retail, control rooms |
| P2.5–P3.9 | 3–10 m | Exhibition booths, conference walls, church sanctuaries |
| P3.9–P6 | 5–50 m | Concert IMAG, live-event side fills, stage backdrops |
| P6–P10 | 10–80 m | Stadium ribbons, roadside billboards, building façades |
Three mistakes that cost real money
1. Buying too fine a pitch for the distance
The most common and most expensive error. Specifying P2.5 for a billboard read from a passing car when P10 would look identical from 15 m away — and cost a fraction. Nobody in the taxi can tell the difference; your budget can.
2. Buying too coarse a pitch for a close audience
The opposite trap. A P6 wall behind a keynote speaker looks fine from the back row and like a fly-screen on the broadcast camera two metres away. Camera distance, not audience distance, sets the pitch here.
3. Ignoring brightness while chasing pitch
Pitch decides sharpness; nits decide whether anyone can see it in daylight. An outdoor screen needs 5,000–8,500 nits regardless of pitch. A beautiful fine-pitch wall at 800 nits is invisible at noon. Spec both together.
Frequently asked
What is LED pixel pitch?
The distance in millimetres between the centre of one LED and the next. P2.5 means 2.5 mm spacing; P10 means 10 mm. Smaller pitch means higher resolution and a closer sharp-viewing distance, at higher cost per square metre.
What pixel pitch do I need?
Match it to your closest viewing distance. The minimum comfortable distance in metres is roughly the pitch number. P10 for billboards seen from 10 m+, P2.5 for retail seen from 2–8 m, P1.5 for camera-facing launch walls.
Is a smaller pixel pitch always better?
No. Past a viewer's comfortable distance the extra resolution is invisible, but you still pay for it. The right pitch is the largest one that still looks sharp where people actually stand.
Does pixel pitch affect brightness?
Not directly — brightness is measured in nits and set by the LED package and driver, not the spacing. But the two must be specified together: an outdoor screen needs both an appropriate pitch and 5,000+ nits to be readable in sun.
