Pillow Sizes & Dimensions Chart: Standard, Queen, King + Specialty Sizes

If you have ever stood in the bedding aisle wondering what size is a standard pillow — or why your new pillow swims inside its case — this guide is for you. Pillow sizes in the US follow a handful of common dimensions, and knowing them makes everything easier: buying pillowcases that actually fit, filling out a bed so it looks right, and choosing the loft and surface area that match how you sleep. Below you will find a complete pillow size chart in inches and centimeters, side-by-side comparisons of standard vs queen vs king, a quick decision guide by bed size and sleep style, and a look at the specialty support sizes — backrest, body, and bolster pillows — that do not show up on most charts.

Pillow Size Chart: All Common Dimensions (Inches & Centimeters)

Here are the seven pillow sizes you will encounter most often, from the everyday standard to oversized and specialty options:

A quick note on tolerances: pillow dimensions describe the fabric shell, not the fluffed pillow, so a "20 x 26" pillow may measure slightly smaller once filled. An inch of variance between brands is normal.

What Size Is a Standard Pillow?

The standard pillow size is 20 inches by 26 inches (51 x 66 cm). It is the most common pillow sold in the US and the default size for most bedding sets. Standard pillows fit twin, full, and queen beds comfortably: one standard pillow centers nicely on a twin, and two sit side by side across a full or queen mattress with a little breathing room.

Because it is the smallest of the main sleeping sizes, a standard pillow is also the easiest to position. Stomach sleepers and people who like a lower, more compact pillow often prefer it, and it is the size most kids graduate into after a toddler pillow.

Standard vs Queen Pillow: What Is the Difference?

The difference between a standard and a queen pillow is length: both are 20 inches wide, but a queen pillow is 30 inches long — 4 inches longer than a standard’s 26 inches. Width, loft, and fill are otherwise the same category to category.

• Standard (20" x 26"): compact, stays put, fits standard cases with a crisp, full look.
• Super standard (20" x 28"): a less common in-between size; it fills a standard case a bit more generously.
• Queen (20" x 30"): extra length for sleepers who shift positions or slide an arm under the pillow at night.

Here is the wrinkle that confuses almost everyone: most pillowcases are sold as "standard/queen." A queen pillow in a standard/queen case simply fills it fuller, while a standard pillow leaves a few inches of loose fabric at the end. Neither is wrong — it is a matter of how plump you like the finished look.

King Size Pillow Dimensions

King pillow dimensions are 20 inches by 36 inches (51 x 91 cm) — a full 10 inches longer than a standard pillow. Two king pillows side by side span about 72 inches, which is why they fill the width of a 76-inch king mattress so much better than standard pillows do.

King pillows are not just for king beds, though. Their extra length makes them a favorite for:

• Sitting up in bed — more surface to lean against while reading or watching TV.
• Restless sleepers — you can roll across a king pillow without falling off the edge.
• Between-the-knees support — some side sleepers use a king pillow as a shorter body pillow.

Remember that king pillows need king pillowcases (20" x 36"–40"); a standard/queen case will not fit.

Euro, Body & Travel: The Specialty Standards

Euro pillow (26" x 26")

The square Euro pillow is primarily decorative — it is the tall pillow at the back of a layered bed — but it earns its keep as a backrest. Propped against a headboard, a firm Euro gives your upper back a flat, supportive surface for reading in bed.

Body pillow (20" x 54" typical)

Body pillows run the full length of your torso, giving side sleepers something to hug while supporting the top knee and arm in a comfortable, stacked position. Slimmer bolster-style versions — like a 48-inch by 8-inch microbead body pillow — are easier to maneuver in bed than a full 54-inch rectangle, and many expecting moms find the squeezable microbead fill comfortable for side-lying support.

Travel pillow (12" x 16")

The smallest common rectangle, sized for airline seats, car trips, camping pads, and little kids. It is also a handy lumbar cushion for an office chair.

What Pillow Size Do You Need? A Quick Decision Guide

By bed size

• Twin or twin XL: one standard pillow.
• Full: two standard pillows.
• Queen: two standard or two queen pillows — queens fill the 60-inch width edge to edge.
• King or California king: two king pillows, or three standards for a fuller headboard line.

By how you sleep

• Side sleepers generally do best with a wider, loftier pillow — queen or king — so the head stays supported when the shoulder takes up space beneath it. Adding a body pillow keeps the top knee and arm from pulling the torso forward.
• Back sleepers are usually comfortable on a standard or queen with medium loft, sometimes with a slim roll under the neck for extra cradle.
• Stomach sleepers tend to prefer the smallest, softest option — a standard or even a travel pillow — to keep the neck from tilting up.
• Readers, gamers, and laptop-in-bed people need something no sleeping pillow provides: a structured backrest. That is where support sizes come in.

Beyond the Chart: Backrest & Support Pillow Sizes

Standard charts stop at sleeping pillows, but if you spend real time sitting up in bed, the more useful size question is "how big should my backrest be?" Reading pillows — sometimes called husband pillows or boyfriend pillows — are shaped like a high-backed chair with padded arms and come in their own size range. Ours run from compact to enormous:

• Standard+ ($44.95): the Standard+ Husband Pillow measures approximately 18 inches tall and 33 inches wide arm to arm — a plush, right-sized backrest for teens, smaller adults, and tighter spaces.
• Medium ($64.95): about 18 inches tall on its own and roughly 23 inches with the detachable neck roll attached — a step up in structure and arm support without dominating the bed.
• XXL ($79.95): the XXL Husband Pillow is the giant of the line — roughly 31 inches of height with the neck roll in place and a seat back about 13.5 inches deep, weighing in around 9 pounds. It is the size we recommend for taller users or anyone who wants their whole upper back supported.

Every size in the line features padded arms, a detachable neck roll, and a removable, machine-washable cover, with a choice of shredded memory foam (firmer) or fiber fill (softer). You can compare all of them in the bedrest pillow collection.

Two more specialty sizes worth knowing:

• Bolster / neck roll (14" x 8" x 8"): a small cylinder that tucks under the neck, lower back, or ankles — the microbead version ($24.95) has a silky, squishable feel.
• Straight body pillow (48" x 8"): the slim microbead design mentioned above ($79.95), sized to hug without hogging the mattress. You will find it alongside C-shaped, L-shaped, and boomerang styles in our body pillow collection.

If you deal with persistent neck or back discomfort, a well-sized pillow can make lounging more comfortable, but it is always worth checking with a healthcare professional about what is going on.

FAQs — Pillow Sizes & Dimensions

What size is a standard pillow?

A standard pillow measures 20 inches by 26 inches (51 x 66 cm). It is the most common US pillow size and fits twin, full, and queen beds — one pillow on a twin, two side by side on a full or queen.

Are standard and queen pillowcases the same?

Usually, yes — most cases are sold as "standard/queen" and fit both. A queen pillow (20" x 30") fills the case snugly, while a standard (20" x 26") leaves a little loose fabric at the open end. King pillows need their own longer king cases.

What are the dimensions of a king size pillow?

A king pillow measures 20 inches by 36 inches (51 x 91 cm) — 10 inches longer than a standard. Two king pillows span about 72 inches, filling the width of a 76-inch king mattress almost perfectly.

What size pillow is best for sitting up in bed?

A backrest-style reading pillow with arms works far better than stacked sleeping pillows because it will not slump. Sizes range from about 18 inches tall (Standard+) up to roughly 31 inches tall with the neck roll (XXL), so you can match the backrest height to your own height and how upright you like to sit.
