The standard pillow measures 20 x 26 inches (51 x 66 cm). It is the most common bed pillow in US homes.

This guide gives you the exact standard pillow size for every type, plus how each one fits your bed. It also shows how to measure a pillow and pick the right one.

Key takeaways:

• Standard is 20 x 26 in. King is 20 x 36 in.
• Most bed pillows are 20 inches wide. They differ in length.
• Pillow length runs across the bed, so bed width decides your size.
• Sizes vary by brand and by country.

Brands vary by an inch or so. Check the label before you buy.

Is the “standard” size the same everywhere? No. In the UK, the standard pillow is about 50 x 75 cm (roughly 20 x 30 in). In Australia, it is 48 x 73 cm. So a US queen pillow matches a UK standard.

Pillow dimensions help you get the perfect fit at home, while accurate measurements matter just as much on the playing field. Explore standard soccer pitch dimensions and field markings to understand how professional and recreational football spaces are measured.

Standard Pillow Size by Type

Bed pillows share one width. Only the length changes.

According to the Sleep Foundation, most bedding brands sell four sizes: standard, queen, king and Euro. Here is how each one works.

• Standard (20 x 26 in): The most common size. It suits side, back and stomach sleepers. It is also the most budget-friendly and widely available size.
• Super standard (20 x 28 in): Two inches longer. It is rare, and it fits a standard case.
• Queen (20 x 30 in): Four inches longer than a standard pillow. It gives restless sleepers more room. A standard pillowcase can also hold a queen pillow, with a slightly higher, firmer feel.
• King (20 x 36 in): The largest of the four common sizes. It works well for active sleepers and for sitting up to read. It needs a king case.
• Body (20 x 54 in): A long pillow for hugging. Side sleepers and pregnant sleepers often use it.

Pillowcase fit: A standard case measures about 20–21 x 30–32 inches. It holds standard and super standard pillows, while king pillows need a king case that runs 20–21 x 36–41 inches. A snug case keeps the pillow from bunching.

Loft matters too. Loft is the pillow’s height, and most bed pillows run about 4 to 7 inches. One sleep brand suggests about 6 inches for side sleepers, 4 to 5 for back sleepers and 2 to 3 for stomach sleepers. Treat this as a starting point.

Pillow Sizes by Bed Size and Specialty Pillows

Pillows lie across the bed, so their length adds up to the bed’s width. That makes the fit easy to check with simple math.

Bed size	Width	Pillows that fit
Twin	38 in	One standard, super standard or queen
Full	54 in	Two standard, or one king
Queen	60 in	Two standard, super standard or queen
King	76 in	Two king, or three standard
California king	72 in	Two king, or three standard

Two king pillows side by side measure 72 inches, which is a tight fit on a 60-inch queen bed. Two queen pillows (60 in) match that bed exactly. King beds are 76 inches wide and California king beds are 72 inches wide. Two king pillows (72 in) fit the California king with no gap.

What other pillow sizes exist? Some pillows are not for sleeping.

• Throw pillows: Square, most often 18 x 18 in (46 x 46 cm). Sizes run from 16 to 28 inches.
• Euro pillows: 26 x 26 in (66 x 66 cm). They sit at the headboard.
• Lumbar pillows: About 12 x 20 in. They support the lower back.
• Travel pillows: About 12 x 16 in (30 x 41 cm). They fit a carry-on.
• Toddler pillows: Typically about 13 x 18 inches. A toddler should not use an adult pillow. Babies should sleep with no pillow at all. A pediatric sleep expert says a child does not need a pillow until the move to a big-kid bed.

How to Measure a Pillow and Choose the Right Size

A pillow label can be missing or wrong. A quick check takes one minute.

How do you measure a pillow?

1. Take off the pillowcase.
2. Lay the pillow flat.
3. Use a rigid ruler or meter stick. A soft tape can warp the reading.
4. Measure corner to corner along the edge.
5. Write the short side first, then the long side. That gives width x length.

How do you choose the ideal pillow size? Check these five things:

• Bed width: Use the table above.
• Sleep position: Side sleepers need more loft than stomach sleepers.
• Movement: Restless sleepers do better with queen or king length.
• Sharing: Make sure two pillows fit side by side.
• Filling: Down, memory foam, latex and polyester feel different at the same size.

Many sleep experts suggest replacing a pillow every 1 to 2 years. Look for lumps, flat spots and neck pain.
