Pillow sizes are confusing because the names do not match bed sizes the way you would expect. A “queen” pillow is not required for a queen bed, and a “king” pillow is mostly a looks choice. And many brands round the numbers differently.
This guide gives you the standard dimensions in one chart, explains which sizes fit each bed, and covers the pillowcase mistakes that make pillows look lumpy or feel cramped.
Pillow Size Chart
| Pillow Size | Typical Dimensions (inches) | Approx. (cm) | Common Use |
|---|---|---|---|
| Standard | 20 x 26 | 51 x 66 | Most beds, sleeping |
| Super standard | 20 x 28 | 51 x 71 | Sleepers who want a little more length |
| Queen | 20 x 30 | 51 x 76 | Queen beds, people who move around |
| King | 20 x 36 | 51 x 91 | King beds, reading, headboard backing |
| Euro | 26 x 26 | 66 x 66 | Decorative backing, reading |
| Body | 20 x 54 | 51 x 137 | Side sleepers, pregnancy |
| Travel | About 12 x 16 to 14 x 20 | About 30 x 40 to 36 x 51 | Travel, kids, small spaces |
These are common industry dimensions. Individual products vary by an inch or two. For example, the Coop Original queen is listed at 29″ x 19″, while the DreamyBlue queen is about 30″ x 20″. Always check the listing.
How Many Pillows Fit Each Bed?
| Bed | Mattress Width | Sleeping Pillows That Fit Across |
|---|---|---|
| Twin / Twin XL | 38″ | 1 standard |
| Full | 54″ | 2 standard |
| Queen | 60″ | 2 standard or 2 queen |
| King | 76″ | 2 king or 3 standard |
| California King | 72″ | 2 king or 2 queen |
You do not have to match pillow size to bed size. Many people with king beds sleep on standard or queen pillows because king pillows are long and can feel bulky.
Which Size Should You Sleep On?
- Standard: the easiest to find cases for, and enough for most people who stay in one position.
- Queen: a few extra inches of room if you move around or have broad shoulders.
- King: good for reading against the headboard or for very active sleepers. Can feel too long for sleeping.
- Body: for side sleepers who want to hug something. See our best body pillow guide.
Size vs Loft: The Measurement That Matters More
Width and length decide how a pillow fits your bed. Loft, the height, decides how it fits your body. A king pillow at the wrong height will hurt your neck just as much as a standard one. As a rough guide:
- Side sleepers: high loft. See our side sleeper loft chart.
- Back sleepers: medium loft, about 3″ to 5″ compressed. See our back sleeper guide.
- Stomach sleepers: low loft, about 2″ to 3″. See our stomach sleeper guide.
Not sure? An adjustable pillow lets you set it yourself. See our best adjustable pillows guide.
Pillowcase Sizes: Avoid These Mistakes
- A standard case on a queen pillow squeezes the pillow, making it firmer and taller than intended.
- A king case on a standard pillow leaves loose fabric. Some people like tucking it in, as one bamboo pillowcase buyer noted.
- Body pillows need a special 20″ x 54″ case. Regular cases do not fit.
- Cube and contour pillows often need their own fitted cases.

FAQ: Pillow Sizes
What size is a standard pillow?
Typically 20″ x 26″.
What is the difference between standard and queen pillows?
Queen pillows are about 4″ longer, typically 20″ x 30″.
Do I need king pillows for a king bed?
No. Two king pillows fill a king bed neatly, but three standard pillows also fit, and many people sleep better on smaller pillows.
Will a queen pillow fit a standard pillowcase?
It will fit, but tightly. It may compress the pillow and make it feel firmer.
What size is a Euro pillow?
Usually 26″ x 26″, used mostly for decoration or as a backrest.
Bottom Line
For most people, a standard or queen pillow is the right size for sleeping. Pick the size that fits your bed and how much you move, then focus on the loft that fits your sleep position. That second choice matters far more for your neck.
