About this tool
Enter your waist and hip measurements and the tool divides one by the other to give a single ratio. The result is grouped into a broad band so you can see where it sits at a glance. This is a general wellness figure, not a diagnosis, and it works best alongside other health measures.
Frequently asked questions
Should I measure over clothes?
No, measure over bare skin or light clothing with the tape level and snug, not tight, for a steadier reading.
Does this replace a doctor's check?
No. It is a simple shape indicator only and cannot diagnose any condition.
