Calculate your foot-to-height ratio from barefoot foot length and height in cm or ft and in, or estimate foot length or height from a ratio you enter.

Measure barefoot foot length from heel to longest toe.

Optional reference comparison
Decimal ratio, such as 0.15, from your chosen reference. Required for reverse solves; blank omits comparison in ratio mode.

Optional. Requires a reference mean ratio; blank omits the normal-model comparison and scenario bounds.

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 โ‰ˆ 0.153846, or approximately 15.385% of height.

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 = 12 / 75 = 0.16, or 16% of height.
