Your healthy weight is 18.5 × your height (m)² to 24.9 × your height (m)². For example, at 1.65 m (5′5″) it is 50.4–67.9 kg (7 st 13 lb – 10 st 10 lb). Enter your height in the calculator for your exact range.

What your healthy weight range means
The range shows the weights at which your health risk from weight is lowest. It is deliberately wide – often around 2½ to 3½ stone between the bottom and the top – because people of the same height differ in frame and muscle.
Inside the range
Great. Keep active and check your weight every few weeks so slow gains do not creep up.
Above the range
Start with a 5% loss. Losing 0.5–1 kg a week is safe and sustainable. Try the calorie deficit calculator.
Below the range
Gain weight gradually with nourishing meals. See the healthy weight gain guide.
Over 65?
A slightly higher weight (BMI 23–28) is usually fine. Avoid unplanned weight loss.
