To measure your waist accurately, you only need a flexible tape measure and a mirror or someone to help.

Quick Scoop

Measuring your waist tells you both your clothing size and gives a rough clue about health risks linked to belly fat. Most health organisations and clothing brands now use a very similar method , based on the midpoint between your lowest rib and the top of your hip bone.

Step‑by‑step: how do you measure waist

  1. Stand up straight, feet hip‑width apart, stomach relaxed and breathing normally.
  1. Find your “waist point”: feel for your lowest rib and the top of your hip bone on one side, then find the halfway point between them; this is usually around or just above your belly button.
  1. Wrap a soft tape measure around this point, all the way around your body, keeping it level (use a mirror or ask someone to check the back).
  1. Make sure the tape is snug but not digging into your skin; don’t pull your tummy in and don’t hold your breath.
  1. Breathe out normally, then read the number on the tape where it meets; that is your waist measurement.
  1. Repeat once more and, if the two numbers differ, use the average.

Mini notes for clothes vs health

  • For clothing size charts, brands usually ask for your “natural waist”: the smallest part of your midsection, typically just below the rib cage and above the belly button.
  • For health checks (like waist‑to‑height ratio or cardio‑metabolic risk), guidance often uses the midpoint between lowest rib and top of hip bone, which is very close to the belly‑button level.
  • Many health tools suggest your waist should be no more than about half your height (waist‑to‑height ratio of 0.5 or lower) as a simple rule of thumb.

Simple example

Imagine you are 170 cm tall and you measure your waist at that midpoint and get 80 cm. Your waist‑to‑height ratio is 80 ÷ 170 ≈ 0.47, which many tools class as within a healthier range (under 0.5).

TL;DR: Find the midpoint between your lowest rib and hip bone, wrap a level, snug (not tight) tape around it, breathe out normally, and read the number—that’s how you measure your waist.
