Full-color LED screen sizes are generally designed based on three factors. First is the installation environment, followed by the planned dimensions of the LED screen's width and height. The third factor is the content typically played, which includes media advertisements, commercial ads, wedding videos, recorded TV broadcasts, high-definition color prints, and more.......

The full-color LED screens can play different video signals based on the environment, such as self-produced LED promotional videos, customer-recorded video clips, TV broadcasts, movie entertainment, commercial advertisements, and more.

Self-produced video content by advertising companies is typically designed in accordance with LED full-color screen ratios. For customer-shot video programs such as travel, wedding anniversaries, corporate promotions, and event selfies, the aspect ratio should be determined by the shooting equipment, such as smartphones, cameras, digital cameras, and camcorders, etc. The standard aspect ratio for broadcast video is usually 4:3, as seen in programs from CCTV and local stations, etc.

The full-color LED displays are categorized into indoor and outdoor types. Generally, indoor LED displays occupy a single-story space, with widths typically unrestricted and heights generally ranging from 2 to 5 meters. Outdoor full-color LED screens are usually not limited by size, allowing flexible adjustments in width and height to cater to the user's preferences. However, a drawback is that the layout of the advertising spots is subject to the owner's decisions.
