About the Ideal Weight Calculator
'Ideal weight' formulas give a rough reference range from height and sex. This shows several (Devine, Robinson, Miller, Hamwi) with their average. No single number is right for everyone — treat it as general context, not a goal.
How it’s calculated
Each formula starts from a base weight at 5 feet of height and adds a set amount per inch above that, differing by sex.
Example calculation
For a 175 cm male, the formulas cluster around 70 kg, with a spread of a few kilograms.
Frequently asked questions
Is there really one ideal weight?
No. These formulas ignore build, muscle, and age, and healthy weight spans a range. Use them as a rough reference, and ask a doctor about what's healthy for you.
How is this different from BMI?
BMI classifies a weight you already have; these formulas suggest a reference weight for your height. Both are general screening tools, not diagnoses.
This tool provides a general, informational estimate only. It is not medical advice and cannot diagnose, treat, or replace guidance from a qualified healthcare professional. Individual health depends on many factors this estimate does not capture. If you have questions about your health, talk to a doctor.
