What is the viewing distance on a led screen?
The viewing distance on a led screen is defined as the correct distance so that our eyes generate a clear and defined vision of what is being reproduced.
A LED screen is formed by points of light, these points can be separated by several millimetres, which is what we call pixel pitch (PP). The technology of LED screens allows us to choose between different pixel pitches, which is why the viewing distance has been taken as a reference to choose the correct pixel pitch for the screen we want to purchase.
Viewing distance does not exclusively define the pixel pitch (PP) we need, since it also has to go in accordance with the total size of the screen. The smaller the screen’s pixel pitch, the more LEDs we have to add per square meter to have a good resolution. On the contrary, with larger screens we can use larger pixel pitches.

Pixel Pitch based on Minium Viewing Distance
In order to select the right Pixelpitch for your application, the following Rule can be applied: Pixelpitch im mm = Minimum Viewing Distance in m.
In practice this means: If the First spectators, who have to perceive the complete picture on the Screen without recognizing separate LEDs, will be placed in about 2 m distance of the Screen, the recommended Pixelpitch for your application will be 2,0 mm at maximum - Other spectators have an accordingly wider average viewing distance.
Other Example: 6 m Minimum Viewing Distance = Maximum 6-7 mm Pixelpitch (recommended) Average Viewing distance will be accordingly wider.
Pixel Pitch based on Visual Acuity or Retina Distance
This is a formulated calculation of the distance a person with 20/20 vision must move away from an LED screen to see a coherent image that is not pixelated. The visual acuity in meters is formulated by multiplying the pixel pitch x 3438.
Visual Acuity: What is 20/20 Vision?
20/20 vision is a term used to express normal visual acuity (the clarity or sharpness of vision) measured at a distance of 20 feet. If you have 20/20 vision, you can see clearly at 20 feet what should normally be seen at that distance. If you have 20/100 vision, it means that you must be as close as 20 feet to see what a person with normal vision can see at 100 feet.
Having 20/20 vision does not necessarily mean you have perfect vision. 20/20 vision only indicates the sharpness or clarity of vision at a distance. Other important vision skills, including peripheral awareness or side vision, eye coordination, depth perception, focusing ability and color vision, contribute to your overall visual ability.
Pixel Pitch based on Optimal Viewing Distance
This is a formulated calculation of the distance in meters for optimal viewing = Pixel Pitch x 2.
