Enter the thigh circumference and height into the calculator to determine the thigh to height ratio. This ratio can be used to assess body composition and distribution of body fat.

Thigh to Height Ratio Formula

The following formula is used to calculate the thigh to height ratio.

THR = TC / H

Variables:

  • THR is the thigh to height ratio
  • TC is the thigh circumference (inches)
  • H is the height of the individual (inches)

To calculate the thigh to height ratio, divide the thigh circumference by the height of the individual.

What is a Thigh to Height Ratio?

The thigh to height ratio (THR) is a measure that compares the circumference of an individual’s thigh to their height. It is sometimes used as an indicator of body composition, particularly the distribution of body fat. A higher ratio may indicate a greater proportion of body fat stored in the lower body, which can be relevant for health assessments and fitness evaluations.

How to Calculate Thigh to Height Ratio?

The following steps outline how to calculate the Thigh to Height Ratio.


  1. First, measure the circumference of the thigh (TC) in inches.
  2. Next, measure the height of the individual (H) in inches.
  3. Use the formula THR = TC / H.
  4. Finally, calculate the Thigh to Height Ratio (THR).
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

Thigh Circumference (TC) = 24 inches

Height (H) = 70 inches
