Frequently asked questions
Why do ideal weight formulas give different answers?
Each was designed for different purposes and populations, mostly using height alone. Looking at the spread of results is more sensible than trusting one.
Do these formulas account for muscle?
No. They use only height and sex, so a muscular person can weigh more and still be healthy. Treat the result as a rough guide.
Which formula should I trust?
None is exact. Look at the overlap between the formulas and use that range instead of one number.
