How to Measure Your Waist Size

Not all brands size the same, and many countries have varying standards for size, which is why knowing your numerical waist size can definitely help you find the best underwear. Follow the below steps to figure out how to measure your waist size:

Step 1: Remove your shirt. You’ll get a much more accurate reading of your waist size– that is, unless you normally tuck your shirt into your underwear.

Step 2: Locate your waist. Seems like a silly step? Well, a lot of people don’t actually know where the waist lies, which leads to some of the biggest sizing issues. If you feel around a bit, looking for where the top of your hips meets the bottom of your rib cage, and the area in between, which should feel more fleshy, and less bony, is your waist. It will generally be right below your belly button. Now you’ll need some measuring tape, which you can find at most stores. All you have to do now is hold the end of the tape against your waist, wrap the tape around, and check out the number. We find it best to let the measuring tape loose and then try again one more time to see if the results match.

      It’s not about what shop has a better product. I am very much into underwear, and have tried MANY brands and styles. I’m a size 28, and not all styles look great on me. It’s about what I feel comfortable in, and what complements MY body type.

    It’s not about the best online shops; it’s more on what makes you feel good… What style best complements YOUR body type.

    I find it strange that you would measure your WAIST when finding your size in a piece of clothing which will sit on your HIPS. There is not an absolute relationship between your waist circumference and hip circumference? This way of measuring seems like an heirloom of a time when underwear actually sat around the waist (if any).

    Personally, I have pretty wide hips, but a fairly trim waist. I suppose for others it might be opposite. You could be fat, but your hips narrow?
