Most muslin changing pad liners are made from cotton muslin and are often labeled 100% cotton. Product listings typically state “cotton” or “100% cotton muslin” as the primary material.
Common sizes include roughly 32" × 16" and 36" × 18", with some smaller liners around 27" × 13"—dimensions intended to fit standard changing pads and shorter liners.
Most liners use elasticized edges—some advertise 360° elastic—so the cover stretches around the pad and stays snug during use.
Options range from single-layer lightweight muslin to two-layer muslin and quilted liners. Some quilted or multi-layer styles pair a cotton top with a waterproof backing (often labeled PVC-free) for extra protection.
Care varies by product, but most liners are machine washable. Listings commonly recommend washing before first use, washing with like colors, and following the item-specific drying or ironing instructions printed on the label.
You’ll find single liners as well as multi-packs—common options include two-packs and sets of three covers—so you can choose based on how often you want backups.
Muslin liners are versatile: use them on bassinets, in strollers or car seats, or keep one in your diaper bag for on-the-go diaper changes.
