What is Pixel Pitch?
Pixel pitch (measured in millimetres) is the distance between the centre of one LED pixel and the centre of the next. A smaller number means pixels are packed more densely — more pixels per square metre, higher resolution, sharper image, and higher cost.
A P1.5mm display has pixels spaced 1.5mm apart. A P6mm display has pixels 6mm apart — six times the spacing. At close range, P6mm looks coarse and blocky. But from 10 metres away, the human eye can't resolve that difference — both look sharp.
The key insight: you only need a fine pixel pitch if people are viewing from close up.A billboard viewed from 50m doesn't need the same resolution as a boardroom display at 3m. Matching pixel pitch to viewing distance is how you spend money wisely.
Rule of Thumb
Min viewing distance (m) ≈ Pixel pitch (mm)
A P2.5mm display looks sharp from ~2.5m. Closer than that and individual pixels become visible. This is a useful starting point — but real-world content type, ambient light, and viewer movement all refine the final spec.
Pixel Pitch by Application
| Pixel Pitch | Min Distance | Best For |
|---|---|---|
| P0.9 – P1.2mm | ~1m | Control rooms, broadcast studios, executive boardrooms |
| P1.5 – P1.9mm | ~2m | Corporate lobbies, conference rooms, retail feature walls |
| P2.5 – P3mm | ~3m | Meeting rooms, retail signage, indoor events |
| P3.9 – P4.8mm | ~4–5m | Stage backdrops, large indoor events, shopping centres |
| P5 – P6mm | ~6m+ | Indoor/outdoor signage, sports venues, warehouses |
| P8 – P10mm | ~10m+ | Outdoor billboards, building facades, large-scale signage |
Content Type Changes the Equation
The viewing distance rule is a starting point, not an absolute. The type of content you're displaying matters significantly:
Text-heavy content
Small text and fine detail require finer pixel pitch than the distance rule might suggest. If your screen shows data tables, presentations, or detailed graphics, err on the finer side.
Video and motion
Moving imagery is more forgiving of coarser pitch because the eye doesn't fixate on individual pixels. Live event backdrops and video walls often use slightly coarser pitch than a static sign would.
Brand and graphics
Bold logos and simple graphics look acceptable at coarser pitches. Photographic content and skin tones benefit from finer resolution.
Mixed use
If your screen switches between presentations and video, spec for the most demanding use case — usually the presentation content.
Don't Over-Spec (or Under-Spec)
Choosing finer pitch than you need wastes money — you're paying for resolution the eye can't perceive at that distance. The cost difference between P2.5mm and P1.5mm can be substantial for a large installation, with no visible benefit if minimum viewing distance is 4m.
Going too coarse creates the opposite problem: content looks pixelated and unprofessional. A corporate boardroom display with P4mm pixel pitch at 2m viewing distance will look blocky and damage your brand perception.
We help you find the sweet spot: sharp enough for your viewing distance and content type, cost-effective for your budget. The right call often saves clients 20–40% on hardware costs without any compromise in perceived image quality.
Leyard Pixel Pitch Range
The Leyard range covers P0.9mm (TXF Series, broadcast/control room) through to P10mm (LA Series, large outdoor). As Australia's official Leyard importer, LUX can source the exact specification your project requires — not just what's in stock.
