Pixel pitch refers to the vertical and horizontal distance between individual LED pixels on an LED media display, otherwise referred to as an LED video wall or LED screen. A common unit of measurement for pixel pitch is millimeters (mm).
The term is often used in the following context “The pixel pitch on this LED media display is 4mm. Therefore, the optimal viewing distance for this LED wall is approximately 4 meters or 13 feet.”
HOW DOES PIXEL PITCH WORK?
One of the steps when purchasing an LED display is deciding which pixel pitch to use. When choosing a pixel pitch, it comes down to a balance between budget and necessity. The decision is generally supported by an experienced audio-visual integrator.
Pixel pitch is directly correlated with image clarity and the cost. As the pixel pitch goes from 4mm to 2mm the number of pixels on a single LED cabinet is 4 times larger. This means the image quality is 4 times higher resolution. It also means the price is 4 times higher. Therefore, the decision on pixel pitch needs to be strategic and take into account the average viewing distance for people looking at the display.
VIDEO EXPLANATION FOR HOW PIXEL PITCH WORKS
The video below gives a complete visual representation to explain pixel pitch. This video was created by LIGHTVU to help make the concept of pixel pitch-perfectly clear. This should be everything needed to understand pixel pitch.
CHOOSING THE RIGHT PIXEL PITCH
To find the right pixel pitch, project planners must first define the minimum viewing distance in feet or meters. This requires careful consideration and attention to the average distance people will be viewing the video wall or large-format LED display from. Once the minimum viewing distance is determined, project planners can consult the following chart:
|Minimum Viewing Distance
|Appropriate Pixel Pitch
|3.28ft | 1m
|4.92ft | 1.5m
|6.56ft | 2m
|8.20ft | 2.5m
|9.84ft | 3m
|13.12ft | 4m
|19.68ft | 6m
|26.24ft | 8m
|32.80ft | 10m
|52.49ft | 16m

WHAT IF I CHOOSE THE WRONG PIXEL PITCH?
If money is no barrier, go with the finest pixel pitch available as it’s the best display technology available today. You can’t go wrong by choosing too fine of a pixel pitch. Unfortunately, this is not a luxury most people have. The budget is always a direct influence in any large format display or digital signage project. This is why choosing the right pixel pitch is so important.
Where LED displays go wrong is when budget-conscious buyers opt for pixel pitches greater than what is recommended for respective minimum viewing distances. These LED displays turn out to be problematic because when the pixel pitch is too large content looks pixelated and low quality. This is the last thing you want when purchasing LED displays.
Trust your audio-visual integrator when it comes to pixel pitch. Professional installers will know the minimum viewing distance to pixel pitch conversion. However, if they tell you any different from what the above chart outlines you should point your integrator to this article.
WORD FROM THE WISE ON CHEAP FINE PIXEL PITCH
The truth of the matter is LED display technology is not cheap. With that said, when LED displays are used correctly it’s worth the investment. Some people will try to beat the system and find cheap fine pitch LED products overseas – all we have to say is good luck.
