Estimate a healthy target weight and range based on your height and gender.
This calculator estimates a reasonable target body weight based on height and gender, using the widely referenced Devine formula, plus a healthy range around that figure. It is a general estimate, not a medical diagnosis.
This calculator converts your height in centimeters to feet and inches automatically, then applies the formula. A healthy range of roughly ±10% around this figure is also shown.
A man who is 175 cm tall (about 5 ft 9 in) has an ideal weight of 50 + 2.3 × 9 ≈ 70.7 kg using the Devine formula. Enter "175" with gender "Male" above to see this result along with a healthy range.
Ideal weight formulas are general estimates based on height alone. They do not account for muscle mass, bone density, or body composition. For a personalized assessment, consult a healthcare professional, and consider pairing this with the BMI Calculator or Body Fat Calculator.
Common formulas (like Devine, Robinson, or Hamwi) estimate a target weight based primarily on height and sex, sometimes adjusted for frame size.
No — they're general population-based estimates, not personalized medical targets. Healthy weight depends on many individual factors like muscle mass, bone structure, and overall health, best discussed with a healthcare provider.
Each formula was developed using different reference populations and methodologies (some originally for medication dosing, not health goals), so results can vary meaningfully between them.
