What is BMI?
BMI or Body Mass Index is a calculation to see if your bodyweight is healthy. It uses you weight and height.
Use our simple BMI calculator below:
BMI ranges
- below 18.5 – you’re in the underweight range
- between 18.5 and 24.9 – you’re in the healthy weight range
- between 25 and 29.9 – you’re in the overweight range
- between 30 and 39.9 – you’re in the obese range
According to the NHS.
Be aware, although your BMI is a good indication as to if you’re carrying too much weight. It cannot tell you if you are carrying too much fat.
This means:
- If you are a muscular adult you may be classed “overweight” or “obese” even though your body fat is low.
- As you get older and lose muscle, you may fall into the “healthy weight” range even though you may be carrying excess fat.
