how to choose LED screen size

I. Core Data Interpretation

The following is a comparison table based on the standard module size of 320×160mm:

Pixel Pitch (Pitch) Module Resolution (W×H) Actual Pixel Density (PPI) Application Scenarios
P1.25 256×128 129 PPI High-end meeting rooms, command centers, close-range viewing
P1.53 208×104 105 PPI High-end meeting rooms, monitoring large screens
P1.83 174×87 88 PPI Meeting rooms, mall signage screens
P1.86 172×86 86 PPI Mainstream meeting rooms, hotel banquet halls (high cost-performance)
P2.0 160×80 80 PPI Standard meeting rooms, teaching screens
P2.5 128×64 64 PPI Mall advertising, stage backgrounds, monitoring walls
P3.0 106×53 53 PPI Outdoor advertising, large stages, long-distance viewing
P4.0 80×40 40 PPI Large outdoor billboards on main roads, landmark screens
Note: Some resolutions (e.g., P3's 106×53) are approximate values calculated by rounding the standard module size divided by the pixel pitch, which do not affect the actual display logic.

II. Comparison with Display Standards (16:9 Aspect Ratio)

The 1080P, 2K, and 4K you mentioned are universal display standards. Let’s calculate the LED screen combination required to achieve these standards:
