Body Frame Size: height-to-Wrist Ratio
Calculate a height-to-wrist ratio and show legacy frame-size categories only as a non-clinical heuristic.
Inputs this tool uses
- Sex used by the formula
- Height
- Wrist circumference
What you get
Height-to-wrist ratio.
How to use the Body Frame Size Calculator
- Enter sex used by the formula, height, wrist circumference.
- Select any method, activity level or option shown on this page, then choose Calculate.
- Read the main result together with the supporting values, method, assumptions and limitations below before using the estimate.
How this calculation works
The height-to-wrist ratio is a legacy frame-size heuristic. The ratio is more important than any simplified category label.
Example calculation
The sample values loaded into the calculator produce 10.6. This example exists to show how the output is structured; replace the sample values with your own inputs for your calculation.
Assumptions and limitations
- Anthropometric formulas are estimates and can differ from direct clinical measurements.
- Results are educational screening/reference values and do not diagnose health conditions.
