Frequently Asked Questions
Which formulas does it use?
It uses four widely cited ideal body weight formulas: Robinson, Miller, Devine and Hamwi. Each was created from population data and gives a slightly different figure.
Why do the formulas disagree?
They were developed at different times from different data, so they weight height a little differently. Showing all four, plus the average, gives a fuller picture than any single number.
What is the healthy weight range?
It is the weight range that gives a normal BMI, between about 18.5 and 24.9, for your height. It is often wider than a single ideal figure and is a useful sanity check.
Is there one correct ideal weight?
No. Ideal weight depends on build, muscle, age and health, which these formulas do not capture. Treat the result as a guide, not a strict target.
Is my information sent anywhere?
No. Everything runs in your browser. Your height never leaves your computer and the tool works offline once loaded.
Is this medical advice?
No. It is for general guidance only. For a target suited to you, speak with a doctor or qualified professional.
