Adult diapers come in a variety of sizes. If you’ve never purchased them before, you may not know where to start with sizing. Like many types of clothing, diapers come in sizes from XS to XL and beyond. Often, these sizes are based on waist measurements. For instance, size XS may measure between 20 and 26 inches at the waist. The XL will be larger—as an example, 43 to 67 inches at the waist. Some manufacturers also include body weight in their size charts to help you choose correctly.
Adult diaper sizing can vary from one manufacturer to the next. It is always best to refer to the size chart provided by the brand to make sure that you’re getting the correct size.
