Body Type (Frame) accuracy and testing
This page documents how Calwarden builds trust for this calculator: source notes, regression-style default tests, limitations, assumptions, unit handling, rounding, and visible change history.
Formula source
- This tool uses data from the Metropolitan Life Insurance Company tables. It compares wrist circumference to height. For example, a man over 5'5" is considered 'Medium' frame if his wrist is between 6.5" and 7.5". Below is Small, above is Large.
Test cases
Default input regression check
Generated from the checked-in default inputs and calculate function.
Inputs
- Gender: Male
- Height Category: avg
- Wrist Circumference: 6.5 in
Expected outputs
- Frame Size: Medium
Known limitations
- This page documents the checked-in calculator logic and does not certify results for every real-world edge case.
- Use the result as a planning estimate unless the calculator page states a stricter purpose.
Assumptions
- Frame size is estimated from height and wrist circumference rather than from full skeletal measurements.
- The categories are broad screening labels, not clinical diagnoses or body-shape classifications.
- Body frame does not directly measure body fat, muscle mass, or athletic performance.
Unit handling
- Gender accepts one of the configured options.
- Height Category accepts one of the configured options.
- Wrist Circumference accepts values in in.
Rounding rules
- Number displays use up to 2 decimal places in the calculator UI.
