Enter the wrist circumference (in) and the body height (in) into the Calculator. The calculator will evaluate the Wrist To Height Ratio. 

Wrist To Height Ratio Formula

WTH = W / H

Variables:

  • WTH is the Wrist To Height Ratio (in/in)
  • W is the wrist circumference (in)
  • H is the body height (in)

To calculate the Wrist To Height Ratio, divide the wrist circumference by the body height.

How to Calculate Wrist To Height Ratio?

The following steps outline how to calculate the Wrist To Height Ratio.

  1. First, determine the wrist circumference (in). 
  2. Next, determine the body height (in). 
  3. Next, gather the formula from above = WTH = W / H.
  4. Finally, calculate the Wrist To Height Ratio.
  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.

wrist circumference (in) = 5

body height (in) = 60

FAQs

What is the significance of the Wrist to Height Ratio?
The Wrist to Height Ratio can help in assessing body frame size and may also be used in determining the most suitable types of physical activities or sports for an individual based on their body build.

How can I accurately measure my wrist circumference?
To accurately measure your wrist circumference, use a flexible measuring tape and wrap it around the smallest part of your wrist, just above the wrist bone. Ensure the tape is snug but not tight, and record the measurement to the nearest quarter inch or half centimeter.

Is the Wrist to Height Ratio used in medical assessments?
While the Wrist to Height Ratio is not commonly used in standard medical assessments, it can provide insights into body composition and frame size. However, other measurements like BMI, waist-to-hip ratio, and body fat percentage are more frequently used in medical contexts.

Can the Wrist to Height Ratio change over time?
The Wrist to Height Ratio is relatively stable in adults since wrist circumference (bone structure) does not significantly change. However, changes in height due to age-related factors could slightly alter the ratio over time.
