Tip: Use your real standing height (no shoes).
Measure on bare skin, after a normal exhale. Keep tape snug—not compressing.
Result
Keep it simple: measure the same way each time. Weekly trends matter more than a single reading.
Why WtHR (not just BMI)?
BMI can’t tell where fat is stored. WtHR focuses on abdominal fat, which is strongly linked to cardiometabolic risk. A simple rule of thumb is to keep your waist circumference below half your height.

Quick thresholds (adult rule-of-thumb)
- < 0.40 — very lean (double-check measurement consistency)
- 0.40–0.49 — generally lower risk zone
- 0.50–0.59 — higher risk zone (consider lifestyle adjustments)
- ≥ 0.60 — highest risk zone (consider professional guidance)
FAQ
Can I track progress with WtHR?
Yes—measure the same way each time (same tape position, same time of day). Weekly trends are most useful.
Is WtHR better than BMI?
Often, yes for abdominal fat. BMI can be distorted by muscle mass and doesn’t show fat distribution.
