How Big Is a Pregnancy Pillow? Sizes vs Bed Size
Of the 14 pregnancy pillows we track, 4 publish a length, and those run 50 in to 69 in long, with widths from 9 in to 30 in. All of them are no longer than a 75-inch twin or full mattress, so width is the number to watch: on a 60-inch queen, the widest published pillow (30 in) leaves 30 in for everyone else.

A queen mattress is sold as 60 inches wide. Two people, a stack of pillows, and now one long curved one that needs a place to go.
We line up the 14 pregnancy pillows we track against common mattress widths, from each maker’s published size.
Length is easy. Width is the question.
Every pillow that publishes a length is no longer than 75 inches, the length of a mattress sold as twin. Width is what comes out of the bed you share. Here’s how the shapes compare.

How much bed is left?
Tap your bed and who sleeps in it. We check every pillow with a published size against it.
Mattress sizes are common US sizes and can run an inch or so off, so measure yours. Pillow sizes come from each maker and can change; a dimmed card is wider than your half or longer than the bed. Check the maker’s label and instructions.
How to read the numbers
We read the longer number a maker lists as length and the shorter as width. With two sleepers, halve the mattress width: a mattress sold as queen at 60 inches wide gives each of you 30 inches, one sold as full at 54 inches gives 27. The bed sizes here are nominal US sizes; measure your own mattress.
Tracked, but the maker doesn’t list a size: Boppy Total Body Pregnancy Pillow, Boppy Side Sleeper Pregnancy Pillow, Boppy Pregnancy Body Pillow, Boppy Cuddle Pregnancy Pillow, Boppy Pregnancy Support Wedge, Frida Mom Full Body Support Pregnancy Pillow, Momcozy U-Shaped Maternity Pillow, Cheer Collection Wedge Pillow for Pregnancy, Frida Mom Compact Support 4-in-1 Pregnancy Pillow, Momcozy J-Shaped Maternity Body Pillow. Check the product page or the maker’s site.

Questions parents ask
Answers come from makers' published specs and official sources linked below.
How big is a full-body pregnancy pillow?
It depends on the maker. The table in this guide shows each maker’s published length and width; some makers don’t list a size.
Will a pregnancy pillow fit on a queen bed?
Compare the published sizes with your mattress. A mattress sold as queen is nominally 60 by 80 inches, so with two sleepers each half is about 30 inches wide; compare that with each pillow’s published width in the table. Measure your own mattress.
Does a U-shaped or C-shaped pillow take more room?
Compare the published widths in this guide, because size varies by maker as much as by shape. Some makers don’t publish a width, so check the product page.
Can I use a pregnancy pillow on a full or twin bed?
It depends on the pillow’s width and who shares the bed. Mattresses sold as full and twin are nominally 54 and 38 inches wide; measure yours and subtract the pillow’s published width to see what’s left.
Can you wash a whole pregnancy pillow?
It depends on the maker. Some list the whole pillow as machine washable, some the cover only, and some say hand wash for the pillow. Check the care label.
Can a pregnancy pillow be used for nursing later?
Some makers list nursing use; the table in this guide shows which. Follow that maker’s instructions and warnings. For sleep guidance, see the AAP’s safe sleep guidance on HealthyChildren.org and ask your pediatrician.
