To measure your waist, stand upright and wrap a flexible tape around your abdomen midway between the bottom of your ribs and the top of your hip bones. Keep it level, snug but not tight, and read it after a normal exhale without sucking in your stomach. Use the same landmark and technique whenever you repeat the measurement.
How to measure your waist step by step
- Stand naturally. Keep your feet together or comfortably close, your weight evenly distributed, and your arms relaxed at your sides.
- Find the measurement point. Feel for the bottom of your ribs and the top of your hip bones. For the WHO STEPS method, measure at the midpoint between the last palpable rib and the top of the hip bone.
- Wrap the tape around your abdomen. Use a flexible measuring tape and keep it horizontal, parallel to the floor, and at the same height across your front and back. For standardized measurements, WHO recommends a stretch-resistant tape.
- Adjust the fit. Let the tape rest against your body without pinching or compressing your skin. Keep your abdomen relaxed.
- Take the reading. Breathe normally for a few breaths, then read the tape after a normal exhale. Do not force your breath out or pull your stomach in.
- Record the result. Note the value and units. For precise measurements using the WHO protocol, read to the nearest 0.1 cm.
Where exactly should the tape go?
Instructions differ because measurement protocols use different landmarks. WHO’s STEPS method places the tape midway between the last palpable rib and the top of the hip bone. The CDC’s simpler public instruction is to place it just above the hip bones. NHLBI’s NHANES III protocol uses the uppermost lateral border of the right iliac crest and keeps the tape horizontal at that level.
These sites are not necessarily interchangeable. If you are comparing readings from a clinician, health survey, or another source, find out which method was used. For personal tracking, pick one method and repeat it consistently.
Common measuring mistakes to avoid
- Measuring at the narrowest visible point or the navel by default: neither is the standard landmark in the cited protocols.
- Letting the tape slope: check that it stays level around your back as well as across the front.
- Pulling the tape tight: it should be snug without pressing into the skin.
- Sucking in your abdomen or holding your breath: keep your stomach relaxed and breathe normally.
- Changing technique between readings: differences in landmark, posture, tape tension, or breathing can make measurements harder to compare.
What a waist measurement can—and cannot—tell you
Waist circumference can help assess health risks associated with excess belly fat, but it is not a direct body-fat measurement or a diagnosis by itself. The CDC says that, in its U.S. guidance, women with a waist measurement more than 35 inches and men with a measurement more than 40 inches are at higher risk. These are not universal diagnostic cutoffs; thresholds and guidance can differ by population, ethnicity, and clinical framework. If you are concerned about your result, discuss it with a qualified clinician.
