Ideal Weight Calculator
Enter your height and sex to see ideal-weight estimates from four well-known formulas, alongside the healthy weight range for your height based on BMI.
How to use
Pick your sex and enter your height in centimeters. The tool shows the healthy BMI range and the Devine, Robinson, Miller and Hamwi ideal-weight figures.
Use the healthy BMI range as your main guide — the formulas give a single target that doesn't account for build, muscle or age.
FAQ
Which formula is best?
There's no single 'best' — Devine is the most widely used, but they all give rough single numbers. The healthy BMI range is usually more practical.
Why do the formulas differ?
Each was derived from different data, so they weight height slightly differently. Seeing all four gives a sensible range rather than one number.
Does it account for muscle or frame?
No — like BMI, these use only height and sex, so very muscular or large-framed people may read high. Treat it as a guide, not a diagnosis.
Is this medical advice?
No — it's a general estimate. For personal targets, talk to a doctor or dietitian.
