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:

- First, determine the total screen area (mm^2).
- The total screen area (mm^2) is given as: 400.

- Next, determine the total body area (mm^2).
- The total body area (mm^2) is provided as: 500.

- 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** = ?**
