What is pixel pitch in LED display?
Pixel pitch is the distance between 2 pixels in LED screen. 1 pixel is the center in 1 LED. The distance between 2 LEDs (center point) is the pixel pitch in LED display. Pixel pitch is also referred to as dot pitch. PX (PhX) is X mm distance between 2 LEDs. For example, P5 (Ph5) is 5 mm distance between 2 LEDs (both in horizontal and vertical direction). Since the pixel pitch reflects the distance between two pixels, a smaller pixel pitch means a smaller distance between pixels, in other words, it means higher pixel density and higher screen resolution.
Why is pixel pitch so important?
The resolution and the close viewing distance.
These 2 are the most important in LED screen. And pixel pitch determines their performance.
In same LED screen's resolution, small pixel pitch will have small dimension.
For example, 1080P (1920x1080 pixels) resolution. P2 LED screen, the dimension will be 3.84x2.16 m; P3 LED screen, the dimension will be 5.76x3.24 m.
In same LED screen's dimension, small pixel pitch will have big resolution (more pixels).
For example, 1.5x1.5 m screen. P2 LED screen, the resolution will be 750x750 pixels; P3 LED screen, the resolution will be 500x500 pixels.
Each LED display, it has close viewing distance (or minimum viewing distance). It's not like LED TV which we can watch in close distance even less than 1 meter(3.28ft). Watching the LED display in proper distance, you will enjoy natural vivid images or videos. But Less than minimum viewing distance, the image and video quality will be bad. More close viewing, you will be distracted by discerning individual LED.
Which one is better for LED screen projects?
3 Tips for helping to choose.
1. Close viewing distance (or minimum viewing distance)
It has distance between screen and viewers. And pixel pitch determines the distance.
Please check below table for each pixel pitch.
Check the distance from screen to close viewer for LED screen project, then select one which is smaller than that distance. The smaller, the better.
2. Video Resolution
Check the video resolution which you want to display on the screen. Smaller pixel pitch LED display will have smaller screen dimension, but it will be expensive than bigger one.

3. Project Budget
Except LED display cost, you may also need to consider structure building cost, installation cost and other cost.
