At a healthy BMI (18.5–24.9) most people look slim to average. At 25–29.9 (overweight) there is usually some extra weight around the waist, hips or face. At 30 and above (obesity) the extra weight is clearly visible. But muscle, frame and fat distribution mean two people with the same BMI can look very different.

| 22 – 24.9 | Healthy (upper half) | Average build; softer shape, especially in women. |
| 25 – 29.9 | Overweight | Some extra weight on the tummy, hips or face; clothes sizes often go up. |

| 35+ | Obesity class 2–3 | Weight affects movement, breathing and joints for many people. |
Why the same BMI looks different
Muscle
A muscular person looks leaner than someone with more fat at the same BMI.
Fat distribution
Apple shapes carry fat around the waist; pear shapes on hips and thighs. See body shape types.
Height
Very tall and very short people can look different at the same BMI.
Age
With age we lose muscle and gain fat, so an older person may look softer at the same BMI.
Frequently asked questions
What does a BMI of 25 look like?
A BMI of 25 is the top of the healthy range. Many people at 25 look “average” – often with a little extra weight around the middle.
What does a BMI of 30 look like?
At BMI 30 most people look noticeably larger around the waist and hips. It is the threshold for obesity.
Can I upload a photo to see my BMI?
