Ideal body weight calculator
Calculate your ideal body weight using several formulas: Devine, Robinson, Miller and BMI=22. Just enter your height and sex.
How we calculate ideal weight
Devine formula (men): 50 + 2.3 × (height cm − 152.4) / 2.54. BMI=22: weight = 22 × height² [m].
Example: man, height 180 cm
Devine: 72.7 kg. Robinson: 72.0 kg. BMI=22: 71.3 kg.
Frequently asked questions
What is ideal body weight?
Ideal body weight is a reference value estimating a healthy weight for a given height and sex. It is calculated using formulas such as Devine, Robinson and Miller, or based on BMI=22.
Which formula is most accurate?
No single formula is perfect. Devine and Robinson are widely used in medicine, while BMI=22 reflects the centre of the healthy BMI range. It is best to compare several results.
Does the calculator account for sex?
Yes. The Devine, Robinson and Miller formulas use different base values and coefficients for men and women, so sex affects the result.
Does muscle mass affect ideal weight?
These formulas do not account for body composition. Athletic people with high muscle mass may exceed the calculated ideal weight while remaining perfectly healthy.
Is BMI the same as ideal weight?
No. BMI is a ratio of weight to height squared, while ideal weight is a target weight in kilograms. BMI=22 is simply one way to estimate ideal weight.
Are the calculator results binding?
No. The result is approximate and is not medical advice. Healthy weight is a range that depends on many factors. Consult a doctor or dietitian.
