Waist Circumference Measurement Protocol
A waist circumference measurement protocol fixes tape site, tension, and timing so monthly trends track central fat—not bloating or inconsistent landmarks.
A waist circumference measurement protocol standardizes where and how you tape the abdomen—same site, same tension, same time of day—so monthly trends reflect fat change, not posture or bloating noise. Measure at the navel or narrowest waist after a normal exhale, tape parallel to the floor, not sucked in.
Common questions
-
Should you measure waist at the navel or narrowest point?
Pick one landmark and never switch—navel is common in research; narrowest waist can differ by an inch. Consistency matters more than which site you choose.
