Pixel pitch is a unique measurement pertinent to TVs and LED Walls. It is one of many technical terms that you should be aware of when you find yourself in the market for an LED Wall display.
One of the most closely-related measurements to pixel pitch is known as dot pitch for computer screens. When computer monitors were first invented, it was relatively easy to see the individual pixels with the naked eye. Those monitors, therefore, had a low dot pitch. These days, when most computer screens come in high resolution, it can be very difficult to make out individual dots unless you get close.
Take this way of thinking about a computer screen, and blow it up to the size of an LED Wall. It’s the overall density of LED clusters on the board.
This is far from mystical jargon that you should leave to the professionals; it is actually a make-it-or-break-it factor affecting your end cost.
LED Walls are usually sold as a number of rectangular, pixelated panels. A lower pixel pitch means more dots and more money. A higher pixel pitch means fewer dots and less money.
Don’t unnecessarily drive up your costs with a pixel pitch that’s too low for your needs!
On the other hand, make sure you are getting what you pay for in terms of your desired resolution.

The True Measurement
Pixel pitch can be measured by taking the distance from the dead center of one LED cluster (pixel), to the dead center of the next LED cluster, measured in millimeters. An extremely small pitch is 0.9 millimeters. An extremely large pitch is 10 millimeters.
It’s easy to get confused: As the pitch measurement goes down, the overall density of pixels goes up! Keep that in mind.
Panels with lower pixel pitch have exponentially more LEDs and therefore cost much more. Higher pixel pitch panels have far fewer LEDs and therefore cost less. It’s not a perfectly proportional equation, but a good rule for determining cost.
This measurement primarily affects the size of the LED Wall necessary to achieve a certain resolution. In order to get a high-definition picture, you need at least 1,920 dots across and 1,080 dots high. That is the widely-accepted standard for HD in the 16:9 aspect ratio, which is the typical widescreen format.
Pixel pitch affects the amount of physical space you will need to line up 1,920 dots. At larger pixel pitch, you’re looking at a massive wall that cannot fit in most rooms. However, as pixel pitch gets lower, it will eventually outpace the HD resolution and drive up the cost.
Optimal Viewing Distance
Besides the desired resolution and budget, optimal viewing distance is also a deciding factor for the pixel pitch. Optimal viewing distance is exactly what it sounds like: How far away is the ideal audience from the screen? This falls in the center of a range between minimum comfortable viewing distance and maximum comfortable viewing distance.
Consider your venue. Is the LED Wall in a retail space, showroom, airport, house of worship, concert venue, arena, or motorway? Each venue has a different optimal viewing distance. When the LED Wall is viewed from farther away, the pixel pitch can be higher.
The farther your audience is from the screen, the larger pitch you will want.
Take your optimal viewing distance in feet and multiply it by 0.1. This will give you an estimate of the pixel pitch you need.
