Choosing the right pixel pitch for an indoor fixed LED video wall is one of the most important decisions in any display project. Get it wrong and you either overspend on resolution your audience can’t see — or end up with a blurry image that undermines your brand.
What Is Pixel Pitch and Why Does It Matter?
Pixel pitch is the distance in millimeters between the center of one LED pixel cluster and the center of the next. A smaller pixel pitch means higher pixel density — more pixels per square meter, sharper image, and a higher price point. For indoor fixed installations, pixel pitch typically ranges from P1.25 to P3.076.
The Golden Rule: Viewing Distance Determines Pixel Pitch
Minimum Viewing Distance (meters) ≈ Pixel Pitch (mm) × 1.0
If your audience sits 2 meters from the screen, a P2.0 display will look perfectly sharp. At 1.5 meters, you need P1.53 or finer.
P1.25 — Broadcast & Command Grade
- Min. viewing distance: ~1.2m
- Best for: Government command centers, broadcast TV studios, financial trading floors
- Why: Premium choice for mission-critical environments requiring ultra-fine detail at close range.
P1.53 — High-End Corporate & Simulation
- Min. viewing distance: ~1.5m
- Best for: Executive boardrooms, simulation and training centers
- Why: Nearly identical visual quality to P1.25 at typical boardroom distances, at lower cost.
P1.86 — Conference Room Standard
- Min. viewing distance: ~1.8m
- Best for: Conference rooms, corporate lobbies, exhibition halls
- Why: The most popular fine-pitch choice worldwide for corporate AV integrators.
P2.0 — Meeting Room & Retail
- Min. viewing distance: ~2.0m
- Best for: Meeting rooms, retail flagship stores, hotel lobbies
- Why: Sweet spot between image quality and cost for 2–4m viewing distances.
P2.5 — Large Venue & Auditorium
- Min. viewing distance: ~2.5m
- Best for: Shopping malls, auditoriums, university lecture halls
- Why: Excellent brightness and visibility at lower cost per square meter.
P3.076 — Large Format & Public Venues
- Min. viewing distance: ~3.0m
- Best for: Airport terminals, ballrooms, transportation hubs
- Why: Strong visual impact at the lowest cost in this series.

FAQ
What pixel pitch for a conference room?
P1.86 or P2.0 for audiences 2–4m away.
Is P1.25 worth the premium over P1.86?
Only for audiences closer than 1.5m or broadcast/mission-critical use.
How to calculate LED wall resolution?
Width (mm) ÷ pixel pitch (mm) = horizontal pixels. E.g. 4000mm ÷ 2.5 = 1600px.
