The three main pillow sizes in the US are standard at 20 x 26 inches, queen at 20 x 30 inches and king at 20 x 36 inches. All three share the same 20-inch short side, so the only real difference is length. Beyond those, you will see Euro squares, body pillows and smaller toddler and travel pillows.
That sounds simple until you stand at a bed with a tape measure, a pile of mismatched cases and a pillow that measures nothing like its label. We fold, measure and pack pillows all day, and most pillow size questions we get are really about fit: on the bed, in the case, and for the person using it.
Pillow sizes chart: standard, queen, king and more
Here are the common pillow sizes and the measurements most US bedding makers use. The standard, queen, king, Euro and body figures match the size guide published by the Sleep Foundation. Super standard, toddler and travel pillows vary more from maker to maker, so treat those rows as typical rather than fixed.
| Size name | Inches | Centimeters (approx.) | Where it usually goes |
|---|---|---|---|
| Standard | 20 x 26 | 51 x 66 | Twin, full and queen beds; the most common sleeping pillow |
| Super standard (jumbo) | 20 x 28 | 51 x 71 | Anyone who wants a little more length in a standard case |
| Queen | 20 x 30 | 51 x 76 | Queen beds; restless sleepers who roll across the pillow |
| King | 20 x 36 | 51 x 91 | King and California king beds; backrest for reading |
| Euro | 26 x 26 | 66 x 66 | Square layer against the headboard, or support behind your back |
| Body | 20 x 54 | 51 x 137 | Side sleepers who like something to hug or put between the knees |
| Toddler | about 13 x 18 | about 33 x 46 | Toddler beds once a child is ready for a pillow |
| Travel | about 12 x 16 | about 30 x 41 | Car trips, camping and carry-on bags |
Two things a pillow size chart cannot show. First, these numbers describe the flat pillow measured seam to seam. Once a pillow is full of fill, the top surface curves and it will measure an inch or two shorter if you lay the tape over the dome.
Second, not every brand sticks to the same pillow sizes. Some cut a pillow slightly narrower or longer and still call it standard. Our own Standard pillow, for example, is 18 x 26 inches, a little slimmer than the 20 x 26 reference size. That is why we always tell people to read the actual measurements on a product page before they buy cases to match. For our own pillows and covers, our pillow size guide lists each size with its matching pillowcase.
What is the difference between standard, queen and king pillows?
On paper it is just length: a queen adds 4 inches to a standard, and a king adds 10. In the hand, those inches change how the pillow behaves.
Standard
A standard pillow is the easiest to move around. You can fold it, push it under your arm or turn it on end without fighting it. That is a big reason so many people with large beds still sleep on standards and keep the bigger sizes for show or for sitting up.
Queen
A queen gives you room to roll from one side to the other without your head running off the edge. If you start the night on your back and end it on your side, those extra 4 inches are where your head lands.
King
A king pillow is long enough to reach across a lot of shoulder, which is why people like it propped against the headboard for reading or watching a show. The trade off is weight and bulk. Some sleepers love the sheer amount of pillow; others find it awkward to adjust in the dark and switch back to queen.
One note from the packing table: a longer pillow holds more fill overall, so a king is heavier and bulkier to handle than the standard version of the same pillow. If you like to scrunch and fold your pillow, sizing up is not always an upgrade.
How many pillows fit on each bed size?
This is the question behind most pillow size searches. Compare the width of the mattress with the length of the pillows laid end to end. Mattress widths below are the usual US sizes.
| Bed | Mattress width | Pillows that fill the width | What it looks like |
|---|---|---|---|
| Twin or twin XL | 38 inches | 1 standard or 1 queen | A standard leaves a little air on each side; a king nearly covers it |
| Full | 54 inches | 2 standard | Two standards total 52 inches, a close fit; two queens hang over |
| Queen | 60 inches | 2 queen | Two queens total exactly 60 inches; two standards leave an 8 inch gap |
| King | 76 inches | 2 king or 3 standard | Two kings total 72 inches; three standards total 78 inches |
| California king | 72 inches | 2 king | Two kings line up edge to edge with the mattress |
Nothing breaks if you ignore the table. Two standard pillows on a queen bed sleep perfectly well; the gap in the middle is only a styling issue. Plenty of couples on king beds sleep on standards and stand a pair of kings behind them as a back row. Bedding threads on Reddit are full of people doing exactly that, usually because king pillows felt too big to bunch up at night.
Building the bed from scratch? Pick the sleeping pillow size you like first, then fill any leftover width with a back row of kings or Euro squares.
What size pillowcase do you need?
Pillowcases carry the same names as pillow sizes, but the fabric is cut longer than the pillow so it can slide on and close or tuck at the open end. That is why a pillowcase rarely measures exactly the same as the pillow inside it.
- Standard case: made for a standard pillow. A queen pillow will usually squeeze in, and the Sleep Foundation guide notes it can feel a bit higher and firmer that way.
- Queen case: fits a queen comfortably. A standard pillow inside one leaves a loose flap at the end that tends to fold under your cheek.
- King case: the only case that properly covers a king pillow. A king will not fit a standard case; you simply run out of fabric.
- Euro and body cases: these pillow sizes need their own cases, which do not swap with the rectangular ones.
King sheet sets almost always ship with king cases, which annoys people who sleep on standards. You can tuck the extra length inside, as most of us do, or buy a separate set of standard cases.
Under the pillowcase, a zip cover is worth thinking about. It keeps sweat and skin oils off the pillow itself, and it has to fit just as well as the case on top. Our zippered cotton percale pillow cover is listed in Standard and Queen sizes, with the zipper hidden along the seam so you do not feel it through the case. Match the cover to the pillow first, then the case to both.
How to measure a pillow you already own
Old pillows lose their tags, and plenty of people have no idea which pillow size is on their bed. Measuring takes about a minute.
- Take the pillow out of its case and cover. Fabric layers add bulk and throw off the reading.
- Lay it flat on the bed or the floor and press the fill down gently along one long edge.
- Run a soft tape measure along the seam, corner to corner, not over the top. Do the same for the short side.
- Round to the nearest inch. A long side close to 26 is standard, close to 30 is queen and close to 36 is king.
If you get something odd, such as 28 inches, you probably have a super standard or a brand that does its own thing. In that case, measure your current case too, and buy the next one by its stated size rather than its name.
While you have the tape out, look at how the pillow springs back after you press it. If it stays flat, size is not your problem. Our pillow sleep science guide covers loft, support and when a pillow is ready to go.
Picking the right pillow size for you
Bed width settles most pillow size decisions, but the person on the pillow matters too. Here is how we talk it through with customers.
- You sleep alone on a twin or full: a standard is easy to handle. A queen works if you roll a lot.
- You share a queen bed: two queens line up neatly. Two standards are fine if you each like to grab and fold your pillow.
- You share a king bed: kings look the most finished. If either of you finds them bulky, sleep on standards or queens and use kings as a back row.
- You read or work in bed: keep at least one king or Euro behind you, whatever you sleep on.
- Your child is moving out of the crib: start with a toddler pillow and step up to a standard later.
Fill matters as much as size. A queen pillow full of dense fill can feel bigger than a soft king. If you are still deciding on the inside of the pillow, our guide to choosing a down alternative pillow walks through the feel of the main synthetic fills.
Our own pillow sizes are Standard at 18 x 26 inches, Queen at 20 x 30 inches and King at 20 x 36 inches. Our washable microfiber pillow in Standard, Queen and King has siliconized microfiber fill inside a 233 thread count cotton percale shell. Queen is the size we suggest most often, because it suits most beds and most sleeping positions.
Bigger pillows need a little more care in the wash. The care steps on the product page are a cold, gentle machine wash with mild liquid detergent, then a low heat tumble dry with dryer balls and a good shake by hand. With a king, give the dryer extra time so the middle dries fully. If the pillow size turns out wrong, you can return it within 30 days of delivery.

Frequently Asked Questions about pillow sizes
Are all standard pillows the same size?
No. Standard pillow sizes in the US sit close to 20 x 26 inches, but brands cut them slightly differently, and some measure closer to 18 inches on the short side. Check the listed measurements, not just the name, before you buy cases.
Can a queen pillow go in a standard pillowcase?
Usually yes. A standard case is cut longer than the pillow, so a queen will slide in snugly. Expect it to feel a little higher and firmer because the fill is squeezed into less space.
Will a king pillow fit in a standard pillowcase?
No. A king pillow is 36 inches long, and a standard case is made for a pillow around 26 inches long, so several inches of pillow stay exposed. Use a king case.
What pillow size is best for a full bed?
Two standard pillows fit a full bed best. Together they measure about 52 inches across a 54 inch mattress. Two queens will hang slightly past the edges.
Should I use king pillows on a king bed?
Only if you like them. Two kings fill the width neatly, but many people prefer standards or queens because they are easier to move, then use kings behind them for looks and reading.
What size is a toddler pillow?
Toddler pillow sizes are usually around 13 x 18 inches, though some makers go a little smaller. They are thinner and smaller than adult pillows, so they need their own toddler pillowcases.
What is a Euro pillow used for?
A Euro pillow is a 26 inch square. In the US it mostly sits against the headboard as a back layer or support for sitting up, while in parts of Europe square pillows are common for sleeping.
Do pillow sizes differ outside the US?
Yes. The UK, Europe and Australia measure in centimeters and use their own pillow size names, which do not line up neatly with US standard, queen and king. Compare the centimeter measurements, not the names, when you buy bedding abroad.
