The below calculator will be your absolute best bet for correct sizing. If for some reason you cannot view it, please read on to manually size yourself. Correct sizing is essential for comfort and product effectiveness. Buying a Belly Wrap that is too large will not wear well under clothing and may affect end results.

How your Belly Wrap should fit

When you try on your Belly Wrap for the first time the ends should barely be touching. That's right if you can pull the Velcro closed it is too big! If the ends of the band are 1-2 inches shy of closing DO NOT EXCHANGE for a larger size. Simply lay down on a flat surface with the band beneath you and try closing it or get a little help from your partner! If you find the band to be extremely tight you can wear it for a few hours each day until you begin to shrink into the size. You’ll soon be wearing it around the clock!
