Healthy Weight Range Calculator
Instead of one target number, it is healthier to aim for a weight range. Enter your height to see the weight range that matches the standard healthy BMI band of 18.5 to 24.9, shown in both kilograms and pounds.
How to use
- Enter your height in centimetres.
- Your healthy weight range appears instantly in both kilograms and pounds.
- Compare the range with your current weight to see where you stand.
Good to know
- BMI is a screening guide, not a diagnosis — muscular people can score high while being healthy.
- Waist size and how you feel day to day matter as much as the number on the scale.
- If you are outside the range, small steady changes beat crash diets every time.
Note
The range inverts the standard BMI band: weight = BMI x height (m) squared, at BMI 18.5 and 24.9. BMI bands do not account for muscle mass, frame or fat distribution. Estimate only — not medical advice.
