Healthy weight range for your height

The weights that give a BMI from 18.5 to 24.9 at this height.
For adults aged 18 and over. BMI is a screening number, not a diagnosis. Calculated in your browser, nothing is sent or saved.
The range is the weight that gives a BMI from 18.5 to 24.9 at your height, which is the WHO healthy weight range for adults. It is a range, not a target, and it says nothing about your build or health.
How the range is worked out
BMI is weight divided by height squared. Rearranged, the lowest healthy weight is 18.5 times your height in meters squared, and the highest is 24.9 times it. At 170 cm, for example, that is about 53.5 kg to 72.0 kg.
How to read it
- The range is wide on purpose: people of the same height can be healthy at very different weights.
- Muscle weighs more than fat, so a muscular person may sit above the range without excess fat.
- Being inside the range does not guarantee good health, and being outside it does not mean poor health. Use it as one reference point.
To see where your own weight falls, use the BMI calculator.
Frequently asked questions
Why is the range so wide?
Frame size, muscle mass and body composition vary between people of the same height. The BMI band is deliberately broad.
Is this my ideal weight?
No. It is a reference range for adults, not an ideal or a goal. Your doctor can help you decide what is right for you.
