Body pillows need covers just like standard pillows, but finding the right one is more complicated. Body pillows come in several shapes and sizes that standard pillowcases simply do not fit. A cover that does not match your pillow’s dimensions bunches up, slides off, or restricts the pillow’s natural shape. Here is a complete guide to body pillow case sizes, shapes, and materials so you can find the right match for your specific pillow.
Standard Body Pillow Dimensions
A standard full-length body pillow measures approximately 50 x 137 centimetres (20 x 54 inches). Most body pillow cases labelled “standard” or “full-length” are designed for these dimensions. However, actual body pillow sizes vary between manufacturers by up to 10 centimetres in both length and width, so always measure your specific pillow before ordering a case.
Some body pillows are oversized, reaching 50 x 150 centimetres or longer. These require XL or king-size body pillow cases. Putting an oversized pillow into a standard case compresses the fill and restricts the pillow’s natural loft, reducing both comfort and support.
Shaped Body Pillow Cases
U-Shaped
U-shaped body pillows require a specifically designed U-shaped cover that wraps around both arms and the connecting base. Standard rectangular cases cannot accommodate the curved shape. U-shaped covers typically come in two sizes: regular (roughly 130 x 70 cm) and large (roughly 150 x 80 cm). The cover must match the exact U-shape of your pillow model, as the curve radius and arm width vary between brands.
C-Shaped
C-shaped body pillows use covers that follow the single curved shape from top to bottom. C-shaped covers are not interchangeable with U-shaped covers even if the overall dimensions appear similar, because the curve geometry differs. Some C-shaped pillow manufacturers sell proprietary covers designed specifically for their product. Check whether your pillow brand offers replacement covers before buying a generic one.
J-Shaped
J-shaped body pillows have a hook at one end and a straight body. J-shaped covers must accommodate the curved head section while fitting snugly along the straight length. The hook section varies significantly in size between different J-shaped pillows, making fit even more model-specific than other shapes.

Materials for Body Pillow Cases
Cotton
Cotton body pillow cases are the most common and versatile option. Breathable, soft, and machine-washable at high temperatures. Cotton in percale weave sleeps cool, while sateen weave feels smoother but retains slightly more warmth. For pregnancy and maternity pillows that tend to trap body heat, percale cotton offers the best breathability. A thread count between 200 and 400 provides a good balance of comfort and durability.
Bamboo Rayon
Bamboo-derived rayon body pillow cases are exceptionally soft and moisture-wicking. The fabric draws sweat away from skin contact points, which matters more with body pillows than standard pillows because the larger surface area creates more heat trapping. Bamboo rayon works especially well for pregnancy pillows where body temperature often runs higher than normal.
Jersey Knit
Jersey knit (T-shirt fabric) body pillow cases have natural stretch that makes them easier to fit over large or unusually shaped pillows. The stretchy fabric conforms to the pillow’s shape without bunching. Jersey feels soft and casual, though it tends to pill after repeated washing. A good choice for everyday use where easy fitting matters more than premium feel.
Minky or Plush
Minky fabric (a soft, plush polyester) creates an ultra-cosy body pillow cover popular with side sleepers and those using body pillows for comfort rather than purely for support. Minky does not breathe well and can feel hot during warm months. Reserve it for cold-weather use or air-conditioned bedrooms.
Closure Types
Zippered
A full-length zip along one side makes fitting and removing the cover quick and easy. The zip also keeps the cover securely in place all night, which matters for body pillows because the larger surface area creates more friction-driven movement during sleep. Look for hidden zips with a fabric flap over the teeth to prevent the zip from pressing against skin.
Envelope
An envelope closure tucks the fabric under the pillow at one end, similar to a standard pillowcase. Simpler and cheaper than zippered designs, but the cover can work loose from the pillow during the night, especially on shaped body pillows where the pillow moves with you as you shift positions.
Tie Closure
Some body pillow covers, particularly for U-shaped and C-shaped pillows, use fabric ties at intervals along one side. Tie closures allow you to partially open the cover for ventilation or partially remove it for washing without taking the entire cover off. Slower to put on than zips but more adjustable.
Care and Washing
Body pillow cases need washing more frequently than you might expect. The larger contact area against your body means more sweat and oil transfer per night. Wash body pillow cases weekly, or every five days if you sleep hot or use the pillow without a top sheet. Machine wash at 40 to 60 degrees on a gentle cycle. Tumble dry on low or air dry to prevent shrinkage, especially for bamboo and jersey fabrics. Our pillow care and washing guide covers fabric-specific instructions.

Buying Tips
Always buy at least two body pillow cases so you have a clean one available while the other is in the wash. Measure your pillow length, width, and girth (circumference) before ordering. For shaped pillows, check whether the manufacturer sells matching cases — these guarantee the best fit. Generic cases often fit approximately but leave loose fabric in the curves.
