BMI Chart in Stone & Pounds
Find your BMI and NHS category from your weight in stone and your height. No calculation needed.
Note: BMI is a screening tool, not a diagnosis. It does not account for muscle mass, bone density, pregnancy, or ethnicity. Athletes and older adults should interpret results cautiously and speak to a GP with concerns.
BMI by Stone Weight and Height
Find your stone weight on the left, then read across to your height.

Understanding Your Result
The NHS defines four adult BMI categories: underweight (below 18.5), healthy (18.5 to 24.9), overweight (25 to 29.9), and obese (30 and above). These thresholds are the same worldwide; only the weight unit on your scale changes.
Notice how dramatically height changes the picture: 12 stone is overweight at 5ft 6in but healthy at 5ft 10in. This is why "is X stone overweight?" has no single answer. For personalised detail, see our ideal weight guide or check your exact figure with the BMI calculator.
