Enter the total screen area (mm^2) and the total body area (mm^2) into the Screen to Body Ratio Calculator. The calculator will evaluate and display the Screen to Body Ratio. 

Screen to Body Ratio Formula

The following formula is used to calculate the Screen to Body Ratio.

SBR = SA / BA * 100
  • Where SBR is the Screen to Body Ratio (%)
  • SA is the total screen area (mm^2) 
  • BA is the total body area (mm^2) 

To calculate a screen to body ratio, divide the screen area by the body area. Multiply by 100 to present a percentage.

How to Calculate Screen to Body Ratio?

The following example problems outline how to calculate Screen to Body Ratio.

Example Problem #1:

  1. First, determine the total screen area (mm^2).
    • The total screen area (mm^2) is given as: 400.
  2. Next, determine the total body area (mm^2).
    • The total body area (mm^2) is provided as: 500.
  3. Finally, calculate the Screen to Body Ratio using the equation above: 

SBR = SA / BA * 100

The values given above are inserted into the equation below and the solution is calculated:

SBR = 400 / 500 * 100 = 80 (%)

Example Problem #2: 

For this problem, the variables required are provided below:

total screen area (mm^2) = 600

total body area (mm^2) = 800

Test your knowledge using the equation and check your answer with the calculator above.

SBR = SA / BA * 100 = ?
