Enter the leg-to-body ratio and the total body length (in) into the Leg Length Calculator. The calculator will evaluate the Leg Length. 

Leg Length Formula

The following two example problems outline the steps and information needed to calculate the Leg Length.

  • Where LL is the Leg Length (in)
  • LBR is the leg-to-body ratio 
  • BL is the total body length (in) 

To calculate the leg length, multiply the leg-to-body ratio by the body length.

How to Calculate Leg Length?

The following example problems outline how to calculate Leg Length.

Example Problem #1:

  1. First, determine the leg to body ratio.
    • The leg to body ratio is given as: 1.25.
  2. Next, determine the total body length (in).
    • The total body length (in) is provided as: 60.
  3. Finally, calculate the Leg Length using the equation above: 


The values provided above are inserted into the equation below and computed.

LL = 60 * 1.25 = 75 (in)

Example Problem #2: 

For this problem, the variables required are provided below:

leg to body ratio = 1.5

total body length (in) = 70

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

LL = LBR * BL = ?
