Height to Hip Width Formula
The following formula is used in this calculator to estimate hip width from height.
Variables (as used by the equation):
- HW is the estimated hip width (inches)
- H is the height of the person (inches)
- If you enter other units in the calculator (ft/cm/m), they are converted internally to inches before applying the formula.
To estimate hip width, multiply height (in inches) by 0.246 and then add 0.5 inches. Because this is a simplified estimate, avoid treating the output as an exact measurement.

What is Hip Width?
“Hip width” can mean different measurements. In everyday use, people often mean hip breadth (standing): the horizontal distance across the widest points of the hips (often near the greater trochanters). This is not the same as hip circumference (a tape-measure distance around the hips).
How to measure (general guidance): Stand relaxed with feet about hip-width apart. Measure the widest left-to-right distance across the hip area, keeping your measuring tool level and parallel to the floor. Different protocols (standing vs. sitting, bony landmarks vs. soft-tissue “widest point”) will produce different values.
How to Calculate Hip Width from Height?
The following steps outline how this calculator estimates hip width from height:
- Enter the person's height (H) in any supported unit (in/ft/cm/m).
- The calculator converts height to inches internally (because the equation constants are in inches).
- Use the formula HW = H × 0.246 + 0.5 to estimate hip width (HW) in inches, then convert back to your selected unit.
- Compare the result to a direct measurement if you need higher accuracy.
Example Problem:
Consider this example to test your understanding of the formula.
Height (H) = 70 inches
Using the formula, the estimated hip width (HW) would be:
HW = 70 * 0.246 + 0.5 = 18.22 inches (approximately)
