How Well Do You Understand The Pixel Pitch Of Video Walls?

When it comes to LED video walls, pixel pitch is one of the most important factors to consider.

This article will teach you everything you need to know about video wall pixel pitch, particularly in terms of viewing distance.

What is pixel pitch?

Video wall pixel pitch describes the distance between 2 pixels in millimeters, sometimes called dot pitch.

This distance defines a lot about the appearance and performance of the LED video wall.

Simply put, a smaller pixel pitch means fewer spaces between pixels. Smaller pixel pitches result in higher pixel density and higher screen resolution.

Video wall pixel pitch is not as well known as resolution. Some even think that pixel pitch and resolution are the same things. This is a significant misunderstanding. They are related, but not the same.

Why is pixel pitch important?

Pixel pitch is very important and affects the optimal viewing distance of the display.

Lower pixel pitch values result in images with smoother edges and finer detail. Even though the viewer is close to the LED video wall, he can enjoy the clear image, not the individual pixels.

It is noteworthy! While higher pixel densities can improve visual quality, that doesn’t mean smaller pixel pitches are always ideal. At greater viewing distances, higher pixel density loses its visual advantage and increases cost.

There is one guideline when determining viewing distance and pixel pitch. That is, the smaller the pixel spacing, the shorter the minimum viewing distance.

Therefore, a 1.2mm screen will have a higher resolution and a smaller optimal viewing distance than a 1.6mm screen.

What pixel pitch is right for you?

The answer is that consumers can determine the pixel pitch value of the LED screen by determining the viewing distance of the screen.

LED screens in the studio, for example, require smaller pixel pitches to provide clear images to nearby viewers. And the LED screen played in front of the public, such as the LED screen hanging on the stage, can use a higher pixel pitch.

The industry generally uses three methods to determine acceptable viewing distances:

  • 10x Rule: This is a great way to quickly calculate the visual sensitivity distance to approximate viewing distance.

  • The calculation formula is: pixel pitch x 10 = approximate viewing distance (in feet)

  • Visual sensitivity distance: also known as retinal distance. It refers to the distance that a person with 20/20 vision must keep from the screen in order to see the LED display to present a coherent image instead of a pixelated image.

  • The calculation formula is: pixel pitch × 3438 = visual sensitivity distance (in feet)

  • Average comfortable viewing distance: This is most people’s estimate of the comfortable viewing distance, which is a subjective estimate.

Although these methods are somewhat instructive, there is no right answer when it comes to determining viewing distance. The viewing distance of a screen is ultimately up to the comfort of the screen owner.

Commonly used pixel pitch measurement methods

The following are some commonly used pixel pitch measurements for your reference only.

Indoor screens generally use LED displays with pixel pitches ranging from 4mm to 20mm.

In a retail store or office environment, a 4mm pixel pitch is generally considered optimal. Because the majority of people are seated near screens.

Airport LED screen typically has a pixel spacing of 5mm to 6mm, which makes it simpler for visitors to see it up close.


A few years ago, only a small portion of the market—such as casinos, shopping centers, and stadiums—used video walls. However, as technology continues to evolve, these types of video walls are used in almost every industry. A complete video wall system offers flexibility and performance that basic solutions cannot.
