Foot to Height Ratio Formula

The following formula is used to calculate the Foot to Height Ratio.

FHR = F / H
  • Where FHR is the Foot to Height Ratio ( )
  • F is the foot measurement (in) 
  • H is the height measurement (in) 

To calculate a foot to height ratio (FTH), divide the foot measurement in inches by the height measurement in inches.

How to Calculate Foot to Height Ratio?

The following example problems outline how to calculate Foot to Height Ratio.

Example Problem #1:

  1. First, determine the foot measurement (in).
    • The foot measurement (in) is given as: 10.
  2. Next, determine the height measurement (in).
    • The height measurement (in) is provided as: 65.
  3. Finally, calculate the Foot to Height Ratio using the equation above: 

FHR = F / H

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

FHR = 10 / 65 = .153

Example Problem #2: 

For this problem, the variables required are provided below:

foot measurement (in) = 12

height measurement (in) = 75

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

FHR = F / H = ?
