The number after the "P" in an LED display specification is the pixel pitch — arguably the single most important technical parameter. It defines resolution, minimum viewing distance, image quality, and cost. Yet many buyers approach LED display purchases without fully understanding how to match pixel pitch to their application. This guide gives you a complete framework.
Pixel pitch is the center-to-center distance between adjacent LED pixels, measured in millimeters. A "P3" display has pixels spaced 3mm apart; a "P2.5" display has pixels 2.5mm apart; and so on.
The fundamental relationship: Smaller pixel pitch = more pixels per square meter = higher resolution = better image quality at close viewing distances — but also higher cost and higher power consumption.
P3 Round LED Screen |
| Pixel Pitch | Pixels/m² | Resolution (1m²) |
| P1.5 | 444,444 | 667 x 667 |
| P2 | 250,000 | 500 x 500 |
| P2.5 | 160,000 | 400 x 400 |
| P3 | 111,111 | 333 x 333 |
| P3.076 | 105,801 | 325 x 325 |
| P4 | 62,500 | 250 x 250 |
| P5 | 40,000 | 200 x 200 |
| P6 | 27,778 | 167 x 167 |
| P8 | 15,625 | 125 x 125 |
| P10 | 10,000 | 100 x 100 |
Minimum Viewing Distance
The minimum viewing distance is the closest point at which the human eye can no longer distinguish individual pixels — the image appears as a smooth, continuous picture. Below this distance, the pixel grid becomes visible, degrading image quality.
The standard formula: Minimum viewing distance (meters) = Pixel pitch (mm) × 2
(Some specifications use a multiplier of 2.5–3 for a more comfortable viewing distance.)
| Pixel Pitch | Min. Viewing Distance (×2) | Comfortable Distance (×3) |
| P2.5 | 5m | 7.5m |
| P3 | 6m | 9m |
| P3.076 | 6.15m | 9.2m |
| P4 | 8m | 12m |
| P5 | 10m | 15m |
| P8 | 16m | 24m |
| P10 | 20m | 30m |
Pixel Pitch vs. Application Type
P1.5–P2.5: Premium Indoor Displays
Typical applications:
◉ Television broadcast studios (presenter backdrop screens)
◉ High-end retail displays (flagship stores, luxury brands)
◉ Corporate boardrooms and video conference walls
◉ Museum and exhibition displays at close interaction distance
Why fine pitch: Viewers stand 2-5 meters from the screen. At these distances, P3+ displays show visible pixels. P2.5 and finer produce a broadcast-quality image at close range.
Cost: The highest cost per square meter of any LED display. Premium indoor fine-pitch panels cost significantly more than P4+ equivalents per unit area.
P3–P4: Standard Indoor Displays
Typical applications:
◉ Shopping mall displays and digital signage
◉ Indoor sports arenas and event screens
◉ Hotel lobbies and conference centers
◉ Indoor rental displays for concerts and events
Why P3-P4: Optimal balance of image quality and cost for indoor environments where minimum viewing distance is typically 6-12 meters.
Aglare's P3.076 product: A precision-engineered indoor pixel pitch that is slightly larger than P3, optimized for a 6-10m viewing distance. We carry P3.076 in stock with fast delivery — a practical choice for rental and event industry buyers who need fast turnaround.
P4–P6: Indoor/Outdoor Transition
Suitable for semi-outdoor applications with covered viewing areas, or indoor applications in large venues (arenas, airports, train stations) where minimum viewing distance is 10-20m.
P5–P10: Standard Outdoor Displays
Typical applications:
◉ Retail advertising billboards (main shopping streets)
◉ Building-mounted digital advertising
◉ Outdoor events and concerts
◉ Sports stadium perimeter boards
Why larger pitch: Outdoor displays are viewed from distances of 10-50+ meters. The human eye cannot resolve individual pixels at these distances regardless of whether the pitch is P5 or P10. Larger pitch allows wider pixel spacing, which reduces the total number of LEDs, lowers cost, and simplifies heat dissipation in a high-temperature outdoor environment.
P10–P16+: Large-Scale Outdoor Advertising
Typical applications:
◉Highway billboards (viewed at 30-200m)
◉Large sports stadium scoreboards (viewed at 50-200m)
◉Building wraps on large commercial structures
Use this decision matrix:
| Factor | Decision |
| Indoor, close view (< 6m) | P2.5 or finer |
| Indoor, medium view (6-12m) | P3–P4 |
| Indoor, large venue (12-25m) | P5–P6 |
| Outdoor, urban (15-50m) | P5–P8 |
| Outdoor, highway (50-200m) | P10–P16 |
| Rental/touring use | P3–P4 (indoor), P5–P6 (outdoor) |
| Budget is a constraint | Use the largest pitch that meets your minimum viewing distance |
Cost Implications
Pixel pitch directly drives cost in two ways:
1.More LEDs per square meter → higher component cost
2.More complex PCB manufacturing for fine pitch → higher production cost
Rough relative cost index (P10 outdoor = 1.0):
| Pitch | Relative Cost/m² |
| P2.5 | 4.5-6.0 |
| P3 / P3.076 | 3.0-4.0 |
| P4 | 2.0-2.8 |
| P5 | 1.5-2.0 |
| P8 | 1.1-1.5 |
| P10 | 1.0 |
