Find your ideal weight by height and sex, with four classic formulas and the healthy weight range based on BMI.
Enter your data
Enter your height and pick your sex. We show four classic estimates plus the healthy weight range.
The Devine, Robinson, Miller and Hamwi formulas differ slightly; the healthy-BMI range is the most practical reference.
Ideal weight ≈ 56.7–76.3 kgInformational estimates, not medical advice. We use standard formulas (WHO, Mifflin-St Jeor, US Navy method). Instant in-browser calculation, no account, no data sent. For medical decisions, consult a professional.
Ideal weight is estimated from height and sex. Classic formulas start from a base weight and add a fixed amount for each inch above 152 cm:
At 1.75 m (male), the Devine formula gives ≈ 70.5 kg, and the healthy weight range (BMI 18.5–24.9) is about 57–76 kg.
It is the weight estimated to be healthiest for a given height and sex. There is no single “right” value but a range, which is why we show several formulas plus the healthy-BMI range.
Classic formulas start from a base weight at 152 cm and add a fixed number of kg for each inch above it. The Devine formula, for example: men 50 kg + 2.3 kg/inch, women 45.5 kg + 2.3 kg/inch.
All use height and sex but with different coefficients from different studies. Results usually vary by a few kilograms; their average is a reasonable estimate.
At the same height, men on average carry more muscle and bone mass, so the reference weight is a few kilograms higher.
The classic formulas do not include age. The healthy weight range based on BMI (18.5–24.9) applies to adults regardless of age.
It is the weight matching a BMI between 18.5 and 24.9 for your height. At 1.75 m that is roughly 57–76 kg. It is the most widely used reference in medical practice.
No. Very muscular people can exceed their “ideal” weight without being overweight. Body-fat percentage gives a truer picture in those cases.
1 foot = 30.48 cm and 1 inch = 2.54 cm. For example, 5 ft 9 in = 5 × 30.48 + 9 × 2.54 = 175.3 cm.
No. It is a guideline. Health also depends on body composition, activity level and other factors; discuss goals with a doctor or dietitian.
