before buying led screen, known LED display length and width, how to calculate the cabinet size and quantity?
Led screen Romania supplier share the calculation of the total number of cabinets and the dimensions of the cabinet.
For example: The customer wants to buy a P8 outdoor full-color LED screen with length of about 9.5 meters and height of about 4.5 meters. The customer will use a waterproof cabinet to make the whole led screen, size of P8 outdoor led module is 256*128mm. we must calculate the number of modules required for each of the length and height before we can calculate the size and quantity of the cabinet. The length of the cabinet is 512, 768, 1024, 1280mm, and the height of the cabinet is 512, 640, 768, 896, 1024, 1152, 1280mm. The following is the specific calculation method:

LED Video Wall Calculator Method
Length: 9500mm / 256mm = 37.109375 (37 long, divided by the length of the screen)
Height: 4500mm / 128mm = 35.15625 (35 hheight, divided by the length of the screen)
Total number of modules: Length 37*Height 35=1295
The actual length of the led display is: 37 pieces * 256mm = 9472mm
The actual height of the led display is: 35 pieces * 128mm = 4480mm
The actual area of the led display is: 9472mm*4480mm=4243456mm2
The length, height and area of led display are all calculated. At this time, the size and quantity of the cabinet need to be calculated. But how do you calculate it? with Excel , you have to know what is the size of the cabinet you need, I take the length of the cabinet is 768mm, then write in the Excel 768 , And then use the led screen length 9472mm divided by the cabinet length 768mm = 12, then use the mouse to click the first 768 do not let go, pull until the last 768, then look at the figure in the lower left corner of the Excel, see 9216, This represents the length of the screen, as shown below:
LED display cabinet calculation method
Then the original calculated screen length is 9472. Using 9472 minus 9216 equals 256, then we will find that the length of 256 is just the length of led module. Obviously it cannot be made into the length of the cabinet, so the 12th cabinet length of the 768 (3 modules) is obviously wrong, then the length of the 12th and 13th cabinet should be changed to 512mm (2 modules). Then we click on the first 768 with the mouse. Let go, until the last 512, found the size of the bottom left corner is 9472, just to meet the length of led screen, the length needs 13 cabinetes, as shown below: So the next step we have to calculate the height of the cabinet.
LED display cabinet height calculation method
Similarly, the height calculation method of the cabinet is the same. First, the screen height is 4480mm divided by the height of the cabinet is 768mm equals 5 cabinetes. As shown in the figure below, the height of the cabinet is 3840mm, and the cabinet is subtracted from the screen 4480mm. 3840mm is equal to 640mm. The height of the cabinet is exactly the height of the screen, as shown in the following figure:
LED display cabinet height
As shown in the figure below, we can see that the following cabinetes of different colors represent four types of cabinetes with different sizes: 768*768mm, 512*768mm, 768*640mm, and 512*640mm.
LED display cabinet size and quantity
1, cabinet size and quantity:
(1) 768*768mm: length 11* height 5=55;
(2) 512*768mm: length 2* height 5=10;
(3) 768 * 640mm: length 11 * height 1 = 11;
(4) 512*640mm: length 2*height 1=2;
Total cabinets: 55+10+11+2=78
the number and size of the cabinet are calculated. Of course, the number and size of the cabinet are not only the same, but can also be made into other cabinet sizes. For example, when the cabinet length is 1024 mm, the cabinet can be calculated according to the above algorithm. Size and quantity, as shown below:
The number of cabinets required
The number and dimensions of the cabinet heights are shown in the following figure:
The number of cabinets required
the length and height of the cabinet have been calculated. As shown in the figure below, we can see that there are 9 colors of the cabinet, so the 9 different colors of the cabinet represent 9 different sizes. The cabinetes are: 1024*1024mm, 768*1024mm, 512*1024mm, 1024*768mm, 768*768mm, 512*768mm, 1024*640mm, 768*640mm, 512*640mm.
The total number of cabinets required
2, cabinet size and number:
(1)1024*1024mm: length 8*height 3=24
(2)768*1024mm: Length 1*High 3=3
(3)512*1024mm: length 1*height 3=3
(4)1024*768mm: length 8*height 1=8
(5)768*768mm: length 1* height 1=1
(6)512*768mm: length 1* height 1=1
(7)1024*640mm: length 8*height 1=8
(8) 768*640mm: Length 1* Height 1 = 1
(9) 512*640mm: Length 1* Height 1 = 1
The total number of cabinets: 24+3+3+8+1+1+8+1+1=50
the cabinet size and quantity calculation method has been introduced, of course, this method is not only for P8 outdoor full color LED display, you can also apply to other different models of led display calculations, if you learn this method, It can be calculated analogously to calculate more cabinet sizes and quantities.
