Ideal Body Weight
Devine, Robinson and Miller formulas side by side.
This ideal body weight calculator estimates a reference weight range from your height and sex using common published formulas. Enter your height and details and read the result as a general guide to where weight might sit for someone of your build and height. It is useful for curiosity, for setting a rough starting point before talking to a health professional, or for understanding what an ideal body weight formula or chart is based on. Treat the result with care. This is an educational estimate, not medical advice, and ideal body weight formulas ignore muscle mass, bone structure, age and medical history. A healthy weight for one person can differ from the number shown. Please consult a doctor or dietitian before making decisions about your weight, diet or health. The tool is free, needs no account, and runs in your browser, so your height and weight details are not uploaded. It works offline after loading.
Frequently asked
What is the ideal body weight formula?
Several formulas exist, and most estimate weight from height and sex. They give a rough reference, not a personal target, so treat the result as an educational estimate.
Is ideal body weight the same as a healthy weight?
Not necessarily. Formulas do not account for muscle, frame size, age or health conditions, so please consult a clinician about what is healthy for you.
Is this ideal body weight calculator for women too?
Yes. You can enter your sex and height, since many formulas use different values for men and women.
Is my data uploaded?
No. The calculation runs in your browser and your details stay on your device.
