Enter your inseam length and height into the calculator to determine your inseam to height ratio. This ratio can help you find the right clothing fit and understand body proportions.

Inseam to Height Ratio Formula

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

IHR = I / H

Variables:

  • IHR is the inseam to height ratio
  • I is the inseam length (inches)
  • H is the height (inches)

To calculate the inseam to height ratio, divide the inseam length by the height.

What is an Inseam to Height Ratio?

The inseam to height ratio is a measure of how an individual's leg length compares to their total height. This ratio is often used in tailoring and clothing design to ensure a proper fit for pants and other garments. It can also be indicative of body proportions and may be used in ergonomics and athletic training to customize equipment and training programs.

How to Calculate Inseam to Height Ratio?

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


  1. First, measure the inseam length (I) from the crotch to the bottom of the leg in inches.
  2. Next, measure the total height (H) in inches.
  3. Use the formula IHR = I / H to calculate the inseam to height ratio.
  4. Finally, compare the ratio to standard clothing sizes or use it for custom tailoring.
  5. After inserting the measurements and calculating the result, check your answer with the calculator above.

Example Problem : 

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