Formula and calculation method
Height-to-wrist ratio = height / wrist circumference, using the same length unit.
Descriptive anthropometric ratio using editable thresholds. It is not a scientifically validated somatotype diagnosis or a predictor of metabolism.
How to use body type calculator
- Set Measurement system by choosing the option that matches your calculation.
- Set Height (cm or inches). The example below uses 175.
- Set Wrist circumference (cm or inches). The example below uses 16.
- Set User-selected small-frame ratio threshold. The example below uses 11.
- Set User-selected large-frame ratio threshold. The example below uses 10.
- Select Calculate to update the result. Reset restores the illustrated inputs. Copy, print or download your own result if you need a record.

Inputs and results explained
Body Type Calculator takes 5 inputs. Fill each one using the same units and conventions, then select Calculate.
- Measurement system: choose one of 2 options, such as Metric (kg, cm), Imperial (lb, inches).
- Height (cm or inches): a number from 1e-06 to 300. The worked example uses 175.
- Wrist circumference (cm or inches): a number of 1e-06 or more. The worked example uses 16.
- User-selected small-frame ratio threshold: a number of 0 or more. The worked example uses 11.
- User-selected large-frame ratio threshold: a number of 0 or more. The worked example uses 10.
The result panel reports Height-to-wrist ratio and Under entered thresholds, so you can see the whole outcome rather than a single figure.
Factors affecting your result
Descriptive anthropometric ratio using editable thresholds. It is not a scientifically validated somatotype diagnosis or a predictor of metabolism.
Changing measurement system changes the scenario being evaluated. Adjust one input at a time when comparing results, keep a copy of the assumptions, and compare values using the same unit and period. A precise arithmetic result does not make an uncertain assumption precise.
Frequently asked questions
How does the body type calculator work?
Height-to-wrist ratio = height / wrist circumference, using the same length unit.
What inputs does Body Type Calculator need?
Enter measurement system, height (cm or inches), wrist circumference (cm or inches), user-selected small-frame ratio threshold, user-selected large-frame ratio threshold. Choose values that correspond to the same situation and measurement convention.
How should I interpret the body type calculator result?
Descriptive anthropometric ratio using editable thresholds. It is not a scientifically validated somatotype diagnosis or a predictor of metabolism.
Are my body type calculator inputs uploaded?
No. The calculation runs in this browser. Favorites, recent tool names, theme and formatting preferences may be saved locally, but calculation inputs are not sent to a calculation server or stored by this website. Shared links do not include entered values.
