How to Calculate LED Screen Size For 4:3

  In order to better show the effect of LED display screens, the ratio  4:3 or 16:9, but there is only  area of ​​the LED screen, there is no specific length and width, Before the installation requires LED display manufacturers calculate the length and width of the display ,we share the calculation size of the LED screen.

  For example: The area of ​​LED display screen is 35 square meters, the customer will buy P8 outdoor led display screen, and the module size of P8 is 256*128mm, calculate the length and width of the display screen according to the ratio of 4:3.

  First, assume that the P8 outdoor LED display is 4X long and 3X wide.

  The area of ​​the display is: 4X*3X=12 square meters. (Note: "X" is an unknown number for the mathematical equation hypothesis, "√" is the root number)

  Solution:

  4X*3X=35

  12X2= 35

  12X2 = 35

  X2 = 2.917

  √X2 =√2.917

  X=1.708

  Display length: 4X = 4 * 1.708 = 6.832m

  Display width: 3X = 3 * 1.708 = 5.124m

  Display area: length * width = 6.832*5.124=35.007m2

  LED display length and width have been calculated, but need specific calculations by the LED module size, such as the P8 module is 256 * 128mm, how many modules need, as follows:

  1. The number of modules required for the display screen is: 6.832/0.256=26.6875

  Number of modules available 26 or 27, number according to customer requirements

  (1) If the length is 26 modules, the display length is: 26*0.256=6.656m

  (2) If the length is 27 modules, the display length is: 27*0.256=6.912m

  2. The number of modules required for display width is: 5.124/0.128=40.03125

  Available 40 or 41 modules, number according to customer requirements

  (1) If the width is 40 modules, the display width is: 40*0.128=5.12m

  (2) If the width is 41 modules, the display width is: 41*0.128=5.248m

  So there are 2 types of display area:

  (1) 6.656* = 5.12 = 34.07872 m2

  (2) 6.912*=5.248=36.274176m2

  The actual LED display area is calculated, of course, different models of LED  modules and the cabinet size is not the same, you can refer to the above method to calculate.
