See the healthy weight range for your height — and how much you would need to lose or gain to reach it.

For healthy adults. These are estimates, not medical advice. Ask a doctor or dietitian about your own targets — especially if you are pregnant, have a health condition or are under 18.

How the healthy weight range is found

lowest healthy weight = 18.5 × height (m)²
highest healthy weight = 24.9 × height (m)²

Example: at 1.75 m the range is 18.5 × 3.0625 = 56.7 kg to 24.9 × 3.0625 = 76.3 kg.
