Ideal Weight Calculator
Estimate a healthy target weight for your height using the Robinson, Miller, Devine and Hamwi formulas, plus the healthy BMI range.
Enter your height to see healthy-weight estimates.
There's no single 'ideal' weight — this shows several well-known estimates for your height and sex, alongside the range that corresponds to a healthy BMI. Use it as a rough guide, not a target to obsess over.
Frequently asked questions
None is definitively 'correct' — they were derived for different purposes and give slightly different numbers. The healthy BMI range is often the most practical guide because it gives a band rather than a single figure. Use the formulas for rough comparison.
These formulas depend only on height and sex, so a very muscular person can weigh more than the 'ideal' figure while still being healthy. Body-composition measures like body fat percentage give a fuller picture.
