What is a healthy waist-to-height ratio?

For most adults, keeping the ratio below 0.5 — i.e. waist less than half your height — is associated with lower cardiometabolic risk. Higher ratios indicate more central fat.

Where do I measure my waist?

Around the narrowest point or at the navel, after breathing out normally, without holding the tape too tight.
