Free health tool
Your healthy weight band, and where you carry it.
Weight on its own tells half the story. Adding your waist measurement gives a clearer picture of risk, particularly for people of South Asian descent.
Your measurements
Health risk can start at a lower weight for some backgrounds, so UK and WHO guidance uses lower BMI cut-offs. We only use this to pick the right range.
Measure your waist halfway between your lowest rib and the top of your hip bone, standing relaxed after breathing out.

50.4–67.8 kg
Healthy weight band for your height (WHO, BMI 18.5–24.9). If your family background is South Asian, East Asian, Middle Eastern or Black, a lower band of 50.4–62.3 kg applies.
Waist-to-height ratio: 0.5
Increased risk range. Keeping your waist to less than half your height is the rule of thumb UK guidance uses.
You are about 0.2 kg above that band. A steady change of 0.25–0.5 kg (½–1 lb) a week is usually realistic and sustainable.
Reference ranges used
- Healthy weight band: BMI 18.5–24.9 (WHO), or 18.5–22.9 if you choose a South Asian, East Asian, Middle Eastern or Black family background (NICE, UK).
- Waist-to-height ratio: below 0.5 is the healthy range, 0.5–0.59 is increased risk and 0.6 or more is high risk (NICE, UK).
