LED Screen Size

Learn to calculate your sign size to determine your sign matrix.

What is Sign Matrix?

Let’s start by refering to the sign matrix, which is the actual space on one face of your LED sign that is populated with pixels. This will contribute of two measurments, the matrix height and the matrix width. 

The matrix numbers are mandatory to compare one company to another. All LED signs have a matrix height and width regardless of resolution. These numbers give the consumer a true comparison allowing us to compare the number of LEDs rather than just the physical cabinet size. 

Read below to learn how to calcualte an LED sign’s matrix. 

LED Sign Matrix

10mm Resolution

Let’s say you are comparing a 4’1″x 7’9″ LED sign size that is a 10mm resolution. First you need to know your matrix height is 112 and your matrix width is 224. Second, you simply multiply the height and width to get the total number of pixels. For example, 112 x 224 = 25,088. That means that the total number of pixels in one face of a 10mm 4’1″ x 7’9″ is 25,088.

16mm Resolution

Now lets compare a 4’1″x 7’9″ LED sign size that is a 16mm resolution. Again, you need to know your matrix height which is 70 and your matrix width which is 140. Second, you simply multiply the height and width to get the total number of pixels. For example, 70 x 140 = 9,800. That means that the total number of pixels in one face of a 16mm 4’1″ x 7’9″ is 9,800.
