How to use this calculator
1. Choose metric or imperial
Toggle the unit system at the top. Enter your height in centimetres, or in feet and inches — the form switches without you re-typing anything.
2. Enter your height
Use your standing height measured without shoes. Even a few centimetres changes the range, so be as accurate as you can.
3. Read the range and target
The headline shows the lowest and highest healthy weight for your height. The target card gives a single mid-range weight at a BMI of 22.

About healthy weight
How is the healthy weight range calculated?
It is the weight that puts you in a BMI of 18.5 to 24.9 for your height. Low weight = 18.5 × height(m)², high weight = 24.9 × height(m)². The target uses the middle of the range at a BMI of 22.
Does a healthy weight depend only on height?
No. This range is a height-based screening guide. Age, sex, muscle mass, frame size and overall health all matter, so treat it as a starting point rather than a fixed goal.
