Standard Pillow Size: 20 x 26 Inches, Queen, King, Body and Euro Sizes and How Cases Fit
Quick answer: a standard pillow is usually 20 by 26 inches. A queen pillow is about 20 by 30 inches, a king pillow about 20 by 36, a body pillow about 20 by 54 and a Euro pillow about 26 by 26. Brands vary by an inch or two, and pillowcases are cut a little larger than the pillow.

Pillow sizes look simple until you shop. A “standard” pillow can be 20 by 26 or 20 by 28. A queen pillow may fit a standard case or not. And you have to match the pillow to the bed and the case. This guide lists the common pillow sizes, how they relate to bed sizes, how cases fit, how to choose a size for your sleep style and why brand charts matter. It overlaps with the pillow cases guide, which covers cases and fabrics, while this one focuses on the pillow itself. Several search results were low-quality mirrors and were ignored.
Common Pillow Sizes
On the core sizes, with some variation between brands.
| Pillow | Typical size (inches) | Notes |
|---|---|---|
| Standard | 20 x 26 | Most sources. One brand lists 20 x 28 |
| Queen | 20 x 30 | Slight variations by brand |
| King | 20 x 36 | One guide gives 20 to 21 by 36 to 41 |
| Body | 20 x 54 | Listed in one source |
| Euro (square) | 26 x 26 | Decor and sleeping |
| Jumbo square | 18 x 18 | Mainly decor |
Some longer standard cases can take a 20 by 30 queen insert, but a true queen case is a more consistent fit. A standard case on a queen pillow will be tight and compress the fill. For decorative pillows and sizes like 18 by 18 and 20 by 20, see the decorative pillows guide.
How Pillows Match Bed Sizes
Bedding sets typically come with: One standard pillowcase for twin, twin XL and full sets. Two for queen, king and California king sets, per a source in the pillow cases guide.
Choose pillow sizes by the width of your bed: Twin or full bed: standard pillows fit well. See the twin mattress dimensions and twin vs full guides. Queen bed: standard or queen pillows. Two queen pillows cover most of the width. King bed: king pillows or two standard pillows per side. See the king vs queen guide.
Personal preference matters more than rules. A king pillow is long, so it can feel big on a smaller bed.
Pillow Size by Sleep Style
Key points: side sleepers. Often prefer a taller, firmer pillow. Size is less important than loft; back sleepers. Medium loft; stomach sleepers. Low loft; reading and lounging. See the reading pillow guide; pregnancy or side support. Body pillows. Ask a doctor for pregnancy advice.
The search covered sizes, not loft. Loft (height) and firmness matter as much as length and width. Check the loft in inches on the product page.
Pillowcase Fit
Pillowcases are generally a little larger than the insert, so a standard pillow in a standard case fits snugly without bunching. For lofty or gusseted inserts, sizing up by 1 to 2 inches is a common suggestion. Always check the case’s listed size and the pillow’s measured size. See the pillow cases guide for fabrics and closures.
Tips:
- Measure your pillow flat, not fluffed.
- Compare with the case’s chart.
- If between sizes, choose the next size up for the case.
- A snug fit looks neat, a loose case wrinkles.
Euro and Square Pillows
Euro shams are 26 by 26 inches and are used for decor at the head of a bed. Square decor pillows come in 18, 20 and 22 inch sizes. See the decorative pillows guide for insert-to-cover rules and arrangement.
Body Pillows
A body pillow is long, about 20 by 54 inches in one source, and used for side sleeping support or hugging. I found only one source for this size, so check the product. Body pillow cases are sold in matching sizes.
Travel and Toddler Pillows
Smaller pillows exist for travel and toddlers. The search did not give sizes. For toddlers, ask a pediatrician about safe sleep and pillow use. Do not use pillows with infants. This is general safety advice.
Care
Key points: wash cases weekly or more often; wash pillows as the label says. See the can you wash pillows guide; replace pillows when flat or lumpy; use pillow protectors.
What are the main strengths and weaknesses?
| Size | Pros | Cons |
|---|---|---|
| Standard | Fits most cases and beds | Smaller on large beds |
| Queen | Slightly longer, good for queen beds | Needs the right case |
| King | Covers more of a large bed | Bulky |
| Body | Full-body support | Takes space |
| Euro | Decorative | Not for sleeping on for many |
How to Choose a Pillow Size
Check your bed size. Choose standard, queen or king. Check loft and firmness for your sleep style. Check the brand’s size chart. Match the pillowcase. Consider a body or reading pillow if needed. Check the return policy.
What mistakes should you avoid?
A few common mistakes are worth avoiding: assuming all standard pillows are the same size; putting a queen pillow in a standard case; choosing by length alone, ignoring loft; measuring a fluffed pillow; buying king pillows for a twin bed; ignoring brand charts.
