How should I measure my waist circumference?

According to WHO guidance, waist circumference should be measured:

  • At the midpoint between the lower margin of the last palpable rib and the top of the iliac crest

  • With you standing, arms relaxed at sides

  • At the end of a normal expiration (breathing out)

  • Using a non-elastic measuring tape held snugly without compressing the skin

NowPatient recommends measuring your waist at the same time of day each month β€” for example, first thing in the morning β€” for the most consistent results.

Step 1 At the midpoint between the lower margin of the last palpable rib and the top of the iliac crest

Step 2 With you standing, arms relaxed at sides

Step 3 At the end of a normal expiration (breathing out)

​Step 4 Using a non-elastic measuring tape held snugly without compressing the skin
