Underpads are typically sold by dimensions and fluid capacity, so the most common questions are about coverage and how much they hold. Standard sizes run around 17" x 24" for chair and wheelchair use up to 23" x 36" and larger for full mattress protection. Higher fluid-ounce ratings suit overnight use and heavier incontinence, while lighter pads work well for daytime changes, procedures, or as an extra layer under a fitted brief. Buying by the case is the norm here — frequent changing keeps skin healthy, so most caregivers plan for regular use rather than stretching a single pad.

These disposable pads lay flat and are easy to place, remove, and discard, which makes routine changes faster and cleaner for both caregiver and patient. They also protect furniture and linens during wound irrigation, spills, and other messy tasks beyond incontinence care.
