How to choose the size for your led displays

First you should confirm the screen is what to do?

If for display message or text post,single,bicolour led display screen is fulfill,sure you can choose any size by yourself, But if for picture,video or animation display,must use full color screen,due to full colour screen at least 50000 pixel to fulfill best picture, So you should calculate the total pixel.
For example: suppose you want to buy display screen outdoor p10 for outdoor full color screen,from the prameter you can see the Pixel per square meter is 10000 Pixel,so the best size is more 50000 / 10000 =5,so five square meter is the least.

May be you will ask,why you can not provide the same size i wanted?sorry,due to the led module size is fix,can not change,and the display screen is assemble by led module, so the only we can do is provided the most close size compare your wanted size.

For example: may be you want a 5M * 4M outdoor led screen p10,due to p10 led module size is 160mm * 160mm,so we will be design 8(length)*5(width)=40 cabinets to you,each cabinet size is 0.64m(L) * 0.8M(W),so final size is 8*0.64=5.12m, 5*0.8=4m,that is most close 5 * 4 m,more information about cabinet,module you can visit our another website outdoor led wall realize

Third:the view distance also another factor for choose the type of led displays,from product list and how to easy estimate the best view distance you will find the detail parameter of the type of led displays and how to estimate the view distance

Best view distance for your led displays

The most easy way estimate the best view distance is by the distance of two pixel of your led displays, for example: display screen outdoor p10 the "10" means the distance of two pixel nearby,sure,the unit is mm,but you can estimate approximate 10M is the nearest view your led displays,and the 10M * 3 =30 M is the most suitable distance view your led screen,So
display screen outdoor p12 best view distance 12-36m
display screen outdoor p16 best view distance 16-48m
display screen outdoor p20 best view distance 20-60m

May be you will ask how long is the farthest view distance,the answer is that it's decide by your led screen altitude,same example by P10 led displays,if your screen is high:3M,the farthest view distance is 3M * 30 =90M,so the 90m is the farthest view distance. So,finally,we know that

The nearest view distance:  the distance of the pixel+M
The suitable view distance:  the distance of the pixel * 3
The farthest view distance:  the altitude of your led displays * 30
