NHS-Aligned BMI Checking
In the UK, the NHS recommends using BMI as a screening tool for weight categories. Our metric-based calculator makes it easy to input your weight in kilograms and height in centimetres for an instant, NHS-style result.
NHS BMI Guidelines
The NHS follows WHO BMI classifications: Below 18.5 (underweight), 18.5–24.9 (healthy), 25–29.9 (overweight), 30–39.9 (obese), and 40+ (severely obese). Pregnant women, children, and some ethnic groups may require adjusted ranges.
