Standard Pillow Sizes Chart: Queen, King & Euro

A standard pillow measures 20 × 26 inches. Queen pillows are 20 × 30 inches, king pillows are 20 × 36 inches, Euro shams are 26 × 26 inches, and body pillows are 20 × 54 inches.

Those five sizes cover nearly every bed and every sleeper. Standard and queen pillows suit most adults, king pillows stretch across wider beds, square Euro shams dress up the bed by day and prop you up for reading by night, and long body pillows give side sleepers something to curl around. Once you know the numbers, shopping for pillows — and the cases that fit them — gets dramatically simpler.

In this guide, you will find the full pillow size chart in inches and centimeters, advice on matching pillows to your bed, a rundown of throw-pillow sizes, and practical tips for measuring and buying. No guesswork, and no dreaded return trip to the store.

A note on units: the bedding world runs on inches, even in countries that otherwise use metric. Every size in this guide is given in inches first, with centimeter conversions alongside, so you can shop confidently wherever you are.

1. Standard Pillow Sizes Chart

The standard pillow — 20 inches wide by 26 inches long — is the workhorse of the bedding world. It fits the vast majority of adult sleepers, it is the easiest size to shop for, and pillowcases in “standard” are sold everywhere. If you only remember one measurement from this guide, make it 20 × 26.

The queen adds four inches of length (20 × 30), which taller sleepers appreciate, and the king stretches to a full 36 inches long (20 × 36) — nearly a yard of pillow. Euro pillows break the rectangle habit entirely at 26 × 26 inches square, while the body pillow runs 20 × 54 inches: four and a half feet of full-body support.

Pillow type	Dimensions	Best for
Standard	20 × 26 in	Everyday sleeping; suits most adults
Queen	20 × 30 in	Taller sleepers; queen beds
King	20 × 36 in	King and California king beds
Euro	26 × 26 in	Decorative shams; reading in bed
Body pillow	20 × 54 in	Side sleepers; full-body support
Travel pillow	Smaller, U-shaped	Naps on planes and in cars
Throw pillow	Varies; usually square	Decoration on sofas and beds

One thing the chart does not show is thickness, sometimes called loft. Two standard pillows can share the same 20 × 26 footprint while one is flat as a pancake and the other plump as a marshmallow. Dimensions tell you the pillow’s outline; loft tells you how it actually feels under your head. Both matter, but only the outline is standardized.

Each pillow size has a matching pillowcase size, and this is where most shopping mistakes happen. A king pillow stuffed into a standard case will look lumpy and feel overstuffed; a standard pillow swimming in a king case will slide around all night. Match the case to the pillow — 20 × 26 pillow, 20 × 26 case — and everything sits the way it should.

To get a feel for these numbers, remember that 20 inches is just over half a yard and 26 inches is just over two feet. If you want to sharpen your sense of the inch itself, our guide to how long an inch is uses everyday objects to make the unit click.

Children, of course, need smaller landing zones. Toddler pillows are noticeably smaller than standard pillows — sized for little heads and little beds — and they are worth buying rather than folding an adult pillow in half. A pillow that fits the sleeper beats a pillow the sleeper has to fight.

Pillow shopping has one more quirk worth knowing: some brands sell “standard/queen” pillowcases as a single size. These are cut to fit both, which really means they fit standard perfectly and queen adequately. If you sleep on queen pillows, proper queen cases are worth the small extra effort to find — the fit is noticeably cleaner.

2. Matching Pillows to Your Bed

The simplest rule: let the bed decide. A pillow that looks generous on a twin can look lost on a king, and a king pillow on a twin bed will hang off the edges like a diving board. Match the pillow’s width to the bed’s width and the whole arrangement looks intentional.

Bed size	Suggested pillows	Notes
Twin	1–2 standard	One is enough; two looks plush
Twin XL	1–2 standard	Same as twin; bed is longer, not wider
Full / Double	2 standard or 2 queen	Queen fills the width more fully
Queen	2 queen or 2 standard	The classic pair, side by side
King	2 king or 3 standard	King pillows span it perfectly
California king	2 king	Slightly narrower bed; kings still fit
Daybed	2–3 Euro + standards	Euros make a sofa-like backrest
Bunk beds	1 standard per bunk	Keep it simple up top

Two sleeping pillows side by side is the default for any bed two people share — one each, no negotiations required. On a queen bed, two queen pillows fill the width edge to edge; on a king, two king pillows do the same job. It is one of those rare cases where the names actually line up.

Euro shams earn their keep as the back row. Stand two 26-inch squares upright against the headboard, lean your sleeping pillows in front of them, and the bed looks made even on lazy mornings. They double as excellent back support for reading, which is why they migrate from decoration to duty every evening.

If you are not sure which bed size you have, check our bed sizes chart before you shop — matching pillows to the wrong mattress size is an easy mistake to avoid.

Guest rooms deserve the same thought as the main bedroom. Two standard pillows per side of the bed covers nearly every visitor, and a spare Euro sham in the closet handles the reader who wants back support. Guests rarely complain about the mattress; they always remember a bad pillow.

There is also a difference between pillows for sleeping and pillows for show, and a well-dressed bed has both. Sleeping pillows live at the back or in the middle where heads actually land; decorative pillows and shams sit in front, where they look good during the day and get moved aside at night. Nobody expects you to sleep on seven pillows — the front rows are for looks.

3. Throw Pillow Sizes

Throw pillows are the jewelry of the sofa: small, decorative, and entirely about looks. Unlike sleeping pillows, their sizes are not standardized — most are square, most are smaller than a standard sleeping pillow, and they are sold by their cover size. A “20-inch throw” means the cover measures about 20 inches square.

Choosing them is more art than science. Odd numbers look better than even ones, varying the sizes keeps the arrangement from looking flat, and restraint matters: three well-chosen throws beat seven crowded ones. On a bed, place throws in front of your sleeping pillows; on a sofa, anchor the ends and work inward.

One practical tip: the insert and the cover are separate purchases more often than beginners expect. A slightly larger insert inside a slightly smaller cover gives that plump, designer look — the corners stay sharp instead of collapsing. Buy the cover for the look you want, then size the insert to fill it generously.

Mixing patterns is where people freeze up, but the rule is forgiving: vary the scale. Pair one large print with one small print and one solid, keep the colors in the same family, and almost any combination works. The pillows are small enough that even a bold choice is low-risk.

Throws are also the cheapest way to change a room with the seasons. Swap heavier textures in for winter, lighter colors for summer, and the whole sofa feels new for the price of a couple of covers. Store the off-season set flat — not compressed — and they will fluff right back up.

Outdoor throw pillows play by slightly different rules. They need weather-resistant covers and quick-dry fills, and their sizes run similar to indoor throws. Bring them inside during heavy rain even if the label says outdoor-safe — “resistant” is not the same as “waterproof,” and the inserts will thank you.

4. How to Measure a Pillow

Measuring a pillow takes ten seconds. Lay it flat, fluff it so it is not folded or compressed, and run a tape measure from one edge to the other — width first, then length. Measure the pillow itself, not the case, and do not include any decorative flange or ruffle in the measurement.

If you are buying a case for a pillow you already own, measure the pillow and buy the matching case size. If you are buying a pillow for a case you already own, measure the case’s opening edge to edge and match the pillow to it. Either direction works as long as the two numbers agree.

Pillows with gussets — the fabric walls around the edge of fancier pillows — can read a little larger than their stated size when new and fluffy. Press the pillow flat before measuring and you will get the honest number. And if tape measures are not your strong suit, a refresher on how to read a measuring tape will make every measurement in this guide easier.

For the centimeter-minded, the math is simple: one inch equals 2.54 centimeters, so a 20-inch width is just under 51 centimeters. The conversion chart at the top of this guide has the common sizes already translated for you.

Measuring for a sham follows the same routine with one twist: shams often have a flange, a flat border of fabric around the edge. Measure the pillow form that goes inside, not the flange — the stated size (26 × 26 for a Euro) refers to the form. The flange is decoration; the form is what has to fit.

5. Pillow Buying Tips

Start with sleep position, not size. Side sleepers generally want a thicker pillow that fills the gap between shoulder and head; back sleepers usually do better with something thinner; stomach sleepers want the thinnest of all. Get the loft right first, then pick the dimensions from the chart above.

Fill material is the next decision, and it is mostly personal. Down and down-alternative feel soft and moldable, memory foam holds its shape and supports firmly, latex sleeps cooler and springs back. There is no universally best fill — only the one that lets you wake up without a crick in your neck.

Replace pillows when they stop doing their job. A pillow that stays folded when you crease it, that has gone lumpy, or that leaves you achy in the morning is done — no matter what the calendar says. Pillow protectors slow the decline by keeping moisture and dust mites out, and they are far cheaper than new pillows.

When you can, try before you buy. Lie on a display pillow the way you actually sleep, not just a quick hand-squish. Many stores and online sellers offer trial periods, and a few nights of real sleep tell you more than any product description. Your neck will cast the deciding vote.

Washing extends a pillow’s life, but check the label first: many synthetic fills survive the machine, down needs careful drying, and memory foam generally wants spot-cleaning only. Whatever the fill, a pillow protector underneath the case is the single cheapest upgrade — it takes the sweat and the washing so the pillow does not have to.

Budget-wise, pillows are one area where the middle of the range is the sweet spot. The cheapest pillows flatten within months, while the most expensive ones often charge for prestige rather than comfort. A solid mid-range pillow with a protector, replaced when it wears out, sleeps better than a luxury pillow kept years past its prime.

Frequently Asked Questions

What size is a standard pillow?

A standard pillow measures 20 × 26 inches (about 51 × 66 cm). It is the most common pillow size, fits most adults, and standard pillowcases are sold everywhere.

What is the difference between queen and king pillows?

Both are 20 inches wide; the difference is length. Queen pillows are 20 × 30 inches and king pillows are 20 × 36 inches. King pillows suit wider beds, while queen pillows suit queen beds and taller sleepers who want extra length.

What size pillowcase fits a Euro pillow?

A 26 × 26 inch Euro sham. Euro pillows are square, so they need square shams — a standard rectangular case will not fit properly.

How many pillows should I put on a queen bed?

Two sleeping pillows (queen or standard) for actual sleep, plus two Euro shams across the back for the made-bed look. Add one or two throw pillows in front if you like the layered style — but the bed still needs to be sleepable.

Final Thoughts

Twenty by twenty-six, twenty by thirty, twenty by thirty-six, twenty-six square, twenty by fifty-four: five sets of numbers that end pillow confusion for good. The standard pillow handles everyday sleep, the queen and king scale up with your bed, the Euro sham makes the bedroom look finished, and the body pillow keeps side sleepers happy. Measure what you have, match the case to the pillow, and buy for your sleep position first. Get those three things right and the humble pillow — the thing your head trusts for eight hours a night — finally gets the attention it deserves. And the next time you are staring at a wall of identical white rectangles in the store, you will know exactly which one is yours.
