Find Your Perfect Ostomy Belt Size
If you're between sizes, choose the larger one for comfort. The belt should be snug, not tight — this prevents it from rolling up.

If you're between sizes, size up for comfort. The belt should not be too snug, as a tight fit may cause the belt to roll up.

*All SIIL Ostomy sizes are equivalent to your usual clothing size. Clothes are designed to fit your body without compressing your stoma. When selecting your size, keep in mind that the garments are stretchy. If you like to wear looser fitting garments, we suggest choosing a size larger than yours, keeping in mind that the waistband will have a softer fit to your body.
