Buy a 160 x 50 cover expecting it to fit a normal bed pillow and you’ll end up with a sack that swallows the insert whole. The number on the label is a body pillow size, a format closer to a dakimakura case than anything in a standard pillow aisle, and it has almost nothing in common with the 20 x 30 in pillow sitting on your bed right now.
The good news: matching a cover to an insert is a two-measurement job, and once you know which measurement matters, the whole thing takes about a minute.
What Insert Does A 160cm x 50cm Cover Actually Fit?
A 160 x 50 cm cover is designed for an insert measuring 160 cm long and 50 cm wide — the same nominal dimensions, nothing more. Listings in this size appear under three interchangeable labels: 160 cm x 50 cm, 63 x 20 in, and 20 x 63 in. They’re the same product class written in two measurement systems.
The conversion is the part that trips people up. 160 cm works out to roughly 63 inches, and 50 cm to roughly 19.7 inches, which most sellers round to 20. So a cover listed as “20 x 63 in” and one listed as “160 x 50 cm” are describing identical dimensions.
Where this size shows up in practice:
- Side sleeping — the length supports the full spine and hip line.
- Pregnancy support — commonly used for belly and back positioning through the second and third trimester.
- Hugging and positioning — a straight rectangular body pillow rather than a curved maternity shape.
Is 160cm x 50cm The Same As A Standard Body Pillow?
No — 160 x 50 cm is longer than the body pillow size most US bedding guides describe. That’s roughly 9 inches shorter than a 160 cm insert.
This matters more than the width difference. For a straight rectangular body pillow, the long dimension is the compatibility factor that decides whether a cover fits at all. A 54-inch insert inside a 63-inch cover leaves a flopping, empty end; a 63-inch insert stuffed into a 54-inch cover won’t close.
Width is the quieter mismatch. Both formats sit near 20 inches wide, so a cover can look right at the opening and still be the wrong length.
Size Comparison At A Glance
| Label | Length | Fits |
|---|---|---|
| 160 x 50 cm | About 63 in | 160 cm insert only |
| 20 x 63 in | 63 in | Same insert, US labeling |
| Standard body pillow | 54 in | Shorter inserts |
| Queen bed pillow | 30 in | Not a body pillow |
| King bed pillow | 36 in | Not a body pillow |
| Standard bed pillow | 26 in | Not a body pillow |
| Travel pillow | 12–14 in | Not a body pillow |
Regular pillowcases, including queen and king, won’t work here. Body pillow covers are their own category.
How Do You Pick The Right Cover Size?
Measure the insert, then match the cover to those numbers — not to the size name printed on your old cover or the one you slept on at a hotel. Covers come in a few standardized lengths, and the two must line up.
- Lay the insert flat and measure from end to end for the long dimension.
- Measure across the middle for the width.
- Compare both numbers against the cover listing in inches or centimeters, converting as needed.
- Confirm whether the seller means exact insert size or finished cover dimensions — a finished cover may run slightly smaller than the insert it holds.
If the insert measures 63 x 20 inches, a 160 x 50 cm cover is the match. A manufacturer’s pillow size chart in the US typically lists bed pillows rather than body pillow formats, which is why 160 x 50 cm won’t appear on most of them — that absence isn’t a red flag, it just means you’re shopping outside the standard chart.
One more check before ordering: straight rectangular covers and curved maternity pillows aren’t interchangeable. A curved full-body pillow won’t slide cleanly into a straight 160 x 50 tube.
Frequently Asked Questions
Will a 160 x 50 cm cover fit a 54-inch body pillow?
No. A 54-inch insert is about 9 inches shorter than a 160 cm (63 in) cover, so the cover will have several inches of empty fabric at one end. The two sizes are different formats and aren’t interchangeable.
Are 160 x 50 cm and 20 x 63 in the same size?
Yes. They’re the same dimensions described in metric and imperial units. Most sellers list both, since 160 cm converts to roughly 63 inches and 50 cm to roughly 20 inches.
Can I use a regular pillowcase on a 160 x 50 cm insert?
No. Standard, queen, and king pillowcases top out around 36 inches and can’t cover a 63-inch insert. You’ll need a body pillow cover sized for the full length.
