How to Calculate the Size of Advertising LED Displays

With the advancement of technology, LED displays are becoming increasingly popular in the advertising industry. Understanding how to calculate the size of an LED display is crucial for those planning to enter the LED billboard business. This article will detail how to calculate LED pixel pitch, the number and size of LED modules, and LED display cabinet dimensions to help you better plan and implement your advertising LED display projects.

What is Pixel Pitch?

Pixel pitch refers to the distance between clusters of LEDs (pixel density) on a screen panel, which directly affects the display resolution. It indicates the distance between adjacent pixels (measured in millimeters). A smaller pitch means less space between pixels, resulting in higher pixel density and higher display resolution.

Pixel pitch is one of the critical parameters that determine the viewing distance of an LED advertising display. Generally, a shorter viewing distance requires a smaller pixel pitch. Common pixel pitches for LED displays include:

P16 LED display
P12 LED display
P10 LED display
P8 LED display
P6 LED display
P3 LED display

Indoor displays typically use smaller pitches (P3 – P10) due to the shorter viewing distance, while outdoor displays use larger pitches (starting from P10).

How to Calculate the Size of an LED Display?

Calculating the size of an advertising LED display involves some basic formulas. We will outline the steps to calculate LED pixel pitch, module dimensions, the number of modules, and cabinet size.

Calculating Pixel Pitch

Calculating pixel pitch is straightforward once you understand the basic formula. Typically, the pixel pitch is:

P10 LED display panel: 10 mm
P6 LED display panel: 6 mm
P3 LED display panel: 3 mm, and so on
Example:

To calculate the pixel pitch for a P5 LED display panel with an area of 1 square meter:

An area of 1 square meter is 1000 mm (length) x 1000 mm (height). There can be multiple dots both lengthwise and heightwise.

Length (L) = 1000 mm / 5 mm = 200 dots
Height (H) = 1000 mm / 5 mm = 200 dots
Total dots = L x H = 200 x 200 = 40,000 dots

Calculating LED Display Size

Length or height = Number of dots x Pitch

Example:

Let's calculate a P10 LED display module that typically has 32 dots in length and 16 dots in width, with a pixel pitch of 10 mm:

Length or height = Number of dots x Pitch

Example:

Let's calculate a P10 LED display module that typically has 32 dots in length and 16 dots in width, with a pixel pitch of 10 mm:

Length or height = Number of dots x Pitch

Example:

Let's calculate a P10 LED display module that typically has 32 dots in length and 16 dots in width, with a pixel pitch of 10 mm:

Number of LED modules = Total area ÷ Module width ÷ Module length

Example 1:

Calculating the number of modules for a P10 LED display wall panel measuring 4m x 3m:

Total area = 4m x 3m = 12 square meters
Module length = 320 mm / 1000 = 0.32 m
Module width = 160 mm / 1000 = 0.16 m
Number of modules = Total area (12㎡) ÷ Module length (0.32 m) ÷ Module width (0.16 m) = 234.375 ≈ 235 modules

Example 2: More Precise Calculation

Total number of LED modules = Number of modules along the width x Number of modules along the length
Number of modules along the length = 4 m ÷ 0.32 m = 12.5 ≈ 12 modules
Number of modules along the width = 3 m ÷ 0.16 m = 18.75 ≈ 18 modules
Total modules = 18 x 12 = 216 modules

Actual size:

Length = 0.32 x 12 = 3.840 m
Width = 0.16 x 18 = 2.88 m

Other Factors Affecting LED Display Size

Pixel pitch directly correlates with the viewing distance of the LED display. The viewing distance is the appropriate distance that allows you to see the display content clearly. When installing an LED display, it's important to consider the maximum, minimum, and optimal viewing distances. Additionally, the appropriate viewing distance is not only related to the pixel pitch but also to the overall size of the LED display panel and specific conditions.

Conclusion

With the advancement of LED technology, LED video displays are gradually becoming an important component of billboard advertising. This digital billboard advertising method is more effective than traditional advertising approaches. Therefore, knowing how to calculate the size of an LED display is crucial if you intend to venture into the advertising LED display business. Mastering these calculation methods can help you better plan and implement your advertising LED display projects, maximizing your advertising impact.
