If you’re here, you might’ve brought home a new mattress and now need the perfectly sized pillow to go along with your purchase. Or, you have the sneaking suspicion that you’ve been sleeping on the wrong size pillow for too long (perhaps your whole life?), and it’s time to make a change. Well, you’ve come to the right place: this is your go-to guide to find the pillow size that’s just right for how you sleep—and even how you want your bed to look and feel.

Let’s start with the basics.

How pillow sizes stack up: a chart

Standard size pillows

Standard pillow size dimensions are 20 x 26 inches (or 51 x 66 cm). Its convenient size makes it one of the most versatile – and most popular size – pillows. Look around any bedroom and this is the pillow you’re most likely to find.

Mattress match: This size goes best with a twin (one pillow) or full-size mattress (with two pillows). If you have a queen bed, you’ll need two; for king beds, three pillows are ideal to cover the width of the mattress.

Best for: Those who alternate sleeping on their stomach and side and tend to bunch up their pillows for added support. (Note: if you flip and turn a lot at night, you may want to shop a few sizes up, so you have more surface area to sleep.)

Pillowcase needed: Standard size works best, but a queen size pillowcase works in a pinch.

Jumbo size pillows

Jumbo pillow sizes — also known as Standard XL or Super-Standard — are a tad larger than Standard (at 20 x 28 inches), and a few inches smaller than a Queen pillow.

Mattress match: It’s perfect for smaller beds—use one pillow on a twin or full-size mattress, and it’ll be all you need. If you like to double up your pillows or just need one for a queen bed, go for two jumbo pillows.

Best for: Sleepers who go from side to stomach throughout the night and need a bit more sleep area than the typical Standard. (If you know, you know.)

Pillowcase needed: Jumbo or Queen.

Queen size pillows

A queen pillow typically measures 20 x 30 inches, which means it’ll fill out your bed surface and provide much more space to spread out and get comfy.

Mattress match: Surprise, surprise…it’s best for a queen bed. Two will look great side by side, with a few inches in between. If you like just one pillow on your twin bed, this could work, too.

Best for: The toss and turners who need more real estate to sleep or for those who are looking for more comfort and luxury—because who doesn’t love the feeling of being in a fancy hotel?

Pillowcase needed: We suggest a queen-size case, so your pillow doesn’t bunch up inside; try a standard or jumbo pillowcase if you’re wanting a firmer, loftier feel.

King size pillows

King size pillow dimensions are generally 20 x 36 inches, and they’ll make you feel positively royal. These are the biggest size, which makes them feel the most luxurious.

Mattress match: Get two of these for your king or California king, and you’re golden. Bonus: If you like the feel of one pillow to fill the frame of a smaller bed (like a twin), here’s a great alternative.

Best for: Back or side sleepers—because it provides added loft without having to fold over a pillow, or to pile on two pillows, for the comfort you’re after. It could even be used as body pillow for kids!

Pillowcase needed: King pillows need a king pillowcase. Game, set, sleep.

Body pillows

This size typically clocks in at 20 x 54 inches and serves as a much-needed “extra pillow” that can be used in a variety of surprising ways—like providing excellent lower-back support or for when you’re sitting up in bed to read or watch TV.

Mattress match: Due to its extra-long length, it can feel like having an additional body in bed, meaning it’s best for a queen- or king-sized bed.

Best for: Side sleepers who want body-hugging comfort; pregnant women who need added support and to stay in the side-sleep position; or for anyone looking to perfect their “pillow-scape” (as a decorative flourish).

Pillowcase needed: Body-size cases only.

How to choose a bed pillow size

A great pillow is an essential part of your total sleep solution. Each size — from standard to king — offers up its own unique benefits. But there are a few key questions you’ll want to ask yourself first before hitting “buy now”:

What’s your mattress size? Typically, it’s either a twin, full, queen, king or California king. And as a rule of thumb: the smaller the bed, the smaller the pillow. But having a variety of sizes around the house won’t hurt — mix, match and combine as you please.

What kind of sleeper are you? We all sleep differently — it could be on your side, your back, on your stomach or a mix of all three. Knowing which one will be key to finding the right pillow size. Plus, if you suffer from other common sleep disruptors, read on for pillow types that can help.

What do you want your bed to look like? It’s all about aesthetics when it comes to our ideal sleep haven. You want a bed that looks as good as it feels, which is why choosing the right number and variety of pillows is important as well.

How much do you want to spend? If you’re looking for a budget option, your best bet is a standard pillow. As you progress up in sizes, the more you’ll need to spend. (But it’s an important investment in your overall quality of life, so well worth it.)
