Pixel pitch and viewing distance
Pixel pitch (such as P3, P6, P10) is the distance in millimeters between the centers of two LEDs. The smaller the pitch, the sharper the image up close and the higher the cost of the display. A widely used rule of thumb says the millimeter value gives, roughly in meters, the closest distance for comfortable viewing: a P3 display is comfortable to watch from 3 meters, a P10 display from 10 meters. That is why P2–P3 is a common choice for lobbies and P6–P10 for facades.
