The on-site environment is usually an important factor when choosing the size of the LED display. Combined with the on-site environment to predict the size in advance and make a budget plan, it can make the manpower, material resources and financial resources play better. In fact, there are many factors that affect the size of the LED display. The first is the viewing distance, Secondly is how the display ratio and the on-site environment exist harmoniously. For indoor LED displays, the safety distance from the ground must also be considered. For outdoor LED display, it is necessary to consider whether the line of sight will be blocked.

The size design of indoor LED display is relatively simple, mainly hanging. It is worth noting that the screen should maintain a distance of not less than 40 cm from the ground. The first is to prevent the mopping water from splashing on the screen. Secondly, the humidity on the ground is relatively easy to get wet. The most important point is that the line of sight of people is not too low. Usually parallel to the LED display, indoor LED display which installed in the conference room, reception hall and aisle is designed according to the ratio of 16: 9, first need to be determined the height, the width can be calculated later, and size of the LED display which installed in the stage and banquet hall is usually wider, so that the visual effect will be better.

There are many installation methods for outdoor LED display screen, such as wall-mounted, upright, cantilevered and suspended. The most common one is generally upright installation, include two types of single column and double column. The size is designed according to the ratio of 16: 9, mainly depends on the area of the screen and the weight of the steel structure. The size of the LED display installed on the wall needs to consider the buildings of on-sites. We can usually notice that the outdoor LED display is very wide, and some LED displays are also very high, then the choice of display content is very important. If it does not match the size of the LED display, and will cause the display content to be compressed and deformed, indirectly It affects the display effect of the advertisement, so when we choose the LED display, we must also consider the currently available advertising content.

In general, what size of display screen to choose, whether indoor or outdoor, the main factors to be considered are the following points, on-site environment (such as temperature, humidity, dust and moisture ...), viewing distance, buildings, creative content, etc.
