Enter the waist and hip circumference into the calculator to estimate the leg size. This calculator helps to approximate the size of one’s legs based on the difference between waist and hip measurements.

Leg Size Formula

The following formula is used to estimate the leg size:

LS = (H - W) * 0.85

Variables:

  • LS is the leg size (inches)
  • H is the hip circumference (inches)
  • W is the waist circumference (inches)

To estimate the leg size, subtract the waist circumference from the hip circumference and multiply the result by 0.85.

What is Leg Size?

Leg size is an informal measurement that can be used to estimate the size of a person’s legs based on the difference between their waist and hip circumferences. It is not a standard measurement used in tailoring or clothing design but can be a useful reference for fitness enthusiasts or individuals tracking their body measurements.

How to Calculate Leg Size?

The following steps outline how to estimate the Leg Size.


  1. First, measure the waist circumference (W) in inches.
  2. Next, measure the hip circumference (H) in inches.
  3. Use the formula LS = (H – W) * 0.85 to calculate the leg size (LS).
  4. Finally, compare the estimated leg size with the calculator above.

Example Problem:

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

waist circumference (W) = 30 inches

hip circumference (H) = 40 inches
