Understanding LED dimensions: a complete guide to LED screen and module sizes.

When buying or designing a LED panel, the dimensions LED Dimensions (pixels per pixel) are one of the first aspects to be considered. They determine the screen resolution, the pixel density and overall visual performance. Whether for a outdoor or a videowall, Understanding how LED dimensions work will help you choose the ideal configuration for your project.

What is Dimensions LED?

LED Dimensions This refers to the physical dimensions of an LED module or panel, usually expressed in width x height (in millimeters). For example, a typical LED module might measure 320 mm x 160 mm or 250 mm x 250 mm. These modules are then combined to form a larger display.

Each module contains a grid of LED pixels. The number of pixels depends on the pixel pitch, which is the distance between the centers of two adjacent pixels (for example, P2.5, P4, P6, etc.). The smaller the spacing between pixels, The higher the resolution, the greater the resolution.

Common dimensions of LED modules

Here are some standard module dimensions used in different types of LED displays:

Module type	Dimensions (mm)	Common pixel step
320 x 160 mm	P2.5, P3.931, P4.81	Indoor and outdoor display
250 x 250 mm	P1.9, P2.6, P2.9	High-resolution video walls for indoor environments.
480 x 320 mm	P5, P6, P8	Outdoors
500 x 500 mm	P2.6, P3.9	Screens and stages for rent
640 x 480 mm	P10, P16	Large-scale outdoor advertising

How LED dimensions affect screen resolution

The resolution of your LED display depends on how many pixels fit within its physical dimensions.

Formula:

Resolution (pixels) = Screen width ÷ pixel spacing x Screen height ÷ pixel spacing

For example, a screen 4 meters wide using a P4 module (4 mm pixel pitch) will have:

Width: 4000 ÷ 4 = 1000 pixels
Height (for a 2.5 m screen): 2500 ÷ 4 = 625
Total resolution = 1000 x 625 = 625,000 pixels

This calculation shows how the same screen size with different pixel spacing can drastically alter image sharpness and cost.

Standard LED cabinet sizes

LED cabinets are structures that hold LED modules together. The size of the cabinet varies depending on the brand and intended use.

Internal fixation: 960mm x 960mm or 640mm x 480mm
Outdoor: 960mm x 960mm, 1280mm x 960mm
Screen for rent: 500mm x 500mm or 500mm x 1000mm

Choosing consistent dimensions for the enclosure and module ensures easier assembly.

How to choose the right Dimensions LED

When choosing the LED size, consider the following factors:

Viewing distance: Pixels with smaller spacing (such as p2.5 or P3) are more suitable for close-up viewing, while pixels with larger spacing (P6, P8, P10) are more suitable for distance viewing.
Installation areaMeasure the available space on the wall or structure to calculate how many modules or cabinets will fit.
Screen ratio: Maintain common aspect ratios, such as 16:9 for video content or 4:3 for signage, to ensure proper scaling.
Budget: Pixels with smaller spacing between them imply higher costs due to the greater number of LED chips per square meter.

Example: Calculating the total screen dimensions

If each cabinet measures 960 mm x 960 mm and you plan to use 4 cabinets horizontally and 3 vertically, the total dimensions of the display area will be:

Width: 960 x 4 = 3840 mm (3.8 m)
Height: 960 x 3 = 2880 mm (2.88 m)

This configuration forms a 3.8m x 2.88m LED screen with pixel spacing depending on the chosen module.

Conclusion

Understanding LED dimensions helps you create a display that fits perfectly in your space, offering the resolution and brightness needed for your project. Whether for a store display, Whether it's a video wall for a church or a project for outdoor areas, selecting the correct module and cabinet size ensures optimal visual performance and long-term reliability.
