Standard Pillow Size: Dimensions for Every Bed

A standard pillow size in the United States is 20 inches by 26 inches. That is the default you will find on most beds and the size most "standard" pillowcases are cut for. From there the sizes step up in length rather than width: a queen pillow is 20 by 30 inches, a king pillow is 20 by 36 inches, and a body pillow runs about 20 by 54 inches. Width stays at 20 inches across nearly all of them.

Knowing the number matters for two practical reasons: pillowcases are sized to the pillow, not to your mattress, and the pillows you choose need to span the width of your bed without crowding each other. Here is the full chart, plus how to match it to your bed.

Standard pillow sizes chart

These are the dimensions used across the U.S. bedding industry. Individual pillows vary by an inch or so depending on fill and construction.

Two of those deserve a note. "Super standard" is an in-between size that not every brand makes, and it is easy to mistake for a queen on a shelf — check the tag. Euro pillows are square and sold in a range of sizes, most commonly 18, 20, 22, 24 and 26 inches on a side; they are for looks and for sitting up in bed, not for sleeping.

Standard vs. queen vs. king, side by side

All three are 20 inches wide. The difference is length:

• Standard, 26 in. Compact. Keeps your head centered and leaves clear space on a narrow bed.
• Queen, 30 in. Four extra inches of room to move at night without rolling off the edge of the pillow.
• King, 36 in. Ten inches longer than standard. Also the size people use upright as a backrest for reading.

Which pillow size fits your bed?

The simple test is to multiply the pillow length by two and compare it to the width of your mattress. Two pillows laid side by side should roughly fill the bed without overhanging it.

A few things that chart does not capture. Two standard pillows on a queen bed leave an eight-inch gap in the middle, which some people like and others find untidy. Two king pillows on a king mattress line up almost exactly edge to edge, which is why king pillows exist at all. And on a split king — two twin XL mattresses side by side — each sleeper usually gets a queen or king pillow of their own, chosen independently, since the whole point of the configuration is that the two sides can differ.

If you are shopping by size, it is easiest to filter that way: standard pillows, queen pillows and king pillows each list what we carry in that size.

Pillowcase and sham sizes

Pillowcases are cut a few inches longer than the pillow they hold so the pillow can be tucked all the way in. Common U.S. pillowcase dimensions:

• Standard case: about 20 x 30 in, for a 20 x 26 pillow
• Queen case: about 20 x 34 in, for a 20 x 30 pillow
• King case: about 20 x 40 in, for a 20 x 36 pillow

Sheet sets bundle the cases that match the set's name, so a queen sheet set normally arrives with queen cases. If you sleep on standard pillows in a queen bed, the cases in the set may be slightly roomier than you need — not a problem, just looser. Going the other direction is the real mismatch: a king pillow will not fit in a standard case, and forcing it compresses the fill and distorts the shape.

Shams are the decorative covers with a finished border and a back opening instead of an open end. They are sold in the same standard, queen, king and euro sizes, and they are meant to sit on display rather than be slept on.

Loft matters as much as length

Length determines fit. Loft — the pillow's height when your head rests on it — determines whether your neck stays in line with your spine. Many pillows, including several latex and memory foam models, are sold in low, mid and high loft rather than one height.

The usual starting points for general comfort:

• Side sleepers have the widest shoulder-to-ear gap to fill and often prefer a higher loft or a firmer pillow.
• Back sleepers usually do well with a mid loft that supports the neck without pushing the chin toward the chest.
• Stomach sleepers generally want the lowest loft available, since a tall pillow tips the head back.

Fill changes how a given loft behaves. Shredded foam and down alternative can be adjusted or fluffed, so the same pillow works for different positions. Solid memory foam and latex hold one shape, which means the loft you buy is the loft you get — worth checking before you order. Plenty of pillows in our pillow collection come in more than one loft for exactly this reason.

One note on what is actually available

Standard, 20 x 26, is the most common size in bedding overall, but it is not the most common size in specialty pillows. Most contoured, zoned, latex and cooling foam pillows are manufactured only in queen and king, because the molded cores are tooled for those lengths. If you have your heart set on a particular foam or cooling model, check which sizes it actually comes in before you plan around a standard case.

Frequently asked questions

What is the standard pillow size in inches?

Twenty inches by 26 inches. That is the U.S. standard, and it is the size "standard" pillowcases and shams are built to hold.

Is a queen pillow the same as a standard pillow?

No. A queen pillow is four inches longer — 20 by 30 inches versus 20 by 26. Both are 20 inches wide, which is why they look similar until you measure them.

Will a king pillow fit on a queen bed?

It fits, but two king pillows measure 72 inches across a 60-inch queen mattress, so they will overhang the sides by six inches each. One king pillow laid sideways across a queen bed works if you like a single long pillow.

How many pillows should go on a bed?

For sleeping, one per person is the practical answer: one on a twin, two on a full, queen or king. Anything beyond that is decorative — euro squares against the headboard, shams in front of them — and comes down to taste.

How do I measure a pillow I already own?

Lay it flat without a case, smooth it out, and measure the width and length seam to seam with a tape measure. Do not stretch the tape into the fabric or compress the fill. Compare the result to the chart above; being an inch off is normal.

Try them before you commit

A pillow is hard to judge from a product page. At our Glendale showroom you can put your head on a standard next to a queen, feel the difference between low and high loft, and test a pillow on the mattress you actually sleep on — or the one you are thinking about. We serve Glendale, Burbank, Pasadena and the greater Los Angeles area, and delivery and setup in LA are free.

Every mattress we sell comes with a 120-night sleep trial, so there is real time at home to be sure of the whole setup, pillow included. Come in and compare, or start browsing pillows by size and loft online.
