Frequently asked questions
- Which formulas are used?
- Devine, Robinson, Miller and Hamwi - the four classic height-based formulas, plus the BMI healthy range for your height.
- Why do the formulas disagree?
- They were built on different studies and populations. The spread between them is normal, so aim for the overall range.
- Is the BMI range more reliable?
- It is a useful sanity check, but BMI does not distinguish muscle from fat and ignores frame size.
- Is my height uploaded?
- No, the calculation runs entirely in your browser.
