What is pixel pitch on an LED screen?
Quick answer
Pixel pitch is the distance in millimeters between the centers of two adjacent pixels on an LED screen, determining the display's resolution and optimal viewing distance.
Pixel pitch is a critical specification for LED video walls and displays. It measures the spacing from the center of one pixel to the center of the next, typically expressed in millimeters (e.g., P2.5 means 2.5mm pitch). A smaller pixel pitch means more pixels per area, resulting in higher resolution and sharper images, especially at close viewing distances.
For live events and fixed installations, choosing the right pixel pitch depends on the audience's viewing distance. Smaller pitches (e.g., P1.2–P2.5) are ideal for close-up viewing like broadcast studios or corporate lobbies, while larger pitches (e.g., P4–P10) suit outdoor stadiums or large venues where viewers are farther away. SSOUNDS integrates LED displays with audio systems for cohesive event solutions, ensuring visual clarity matches audio precision.
Pixel pitch also affects cost and brightness. Smaller pitches require more LEDs and tighter manufacturing tolerances, increasing price. However, they offer better image quality. For outdoor use, larger pitches can achieve higher brightness levels needed to compete with sunlight. Always balance pixel pitch with the specific application and budget.
Key things to consider
- Measured in millimeters from pixel center to pixel center; smaller pitch = higher resolution.
- Optimal viewing distance = pixel pitch × 1000 (e.g., P3.9 is best viewed from ~3.9m away).
- Common pitches: P1.2–P2.5 for indoor/corporate, P3.9–P6 for events, P8–P10+ for outdoor.
- Smaller pitch costs more but delivers sharper images; larger pitch offers higher brightness for outdoor use.
- Always match pixel pitch to audience distance and content type (text, video, graphics).
