A Guide to Standard Pillow Dimensions

A Guide to Standard Pillow Dimensions

Knowing standard pillow dimensions is essential when picking out new bedding. Not only does the size of a pillow affect the look and feel of your room, but it can also impact the quality of your sleep.

In this comprehensive guide, we'll take a deep dive into standard pillow dimensions — answering everything from what size is a regular pillow to what type of pillowcases you'll need. 

We'll also cover how to measure your pillows and what to consider when picking out a new set.

Standard Pillow Dimensions

The size of a standard pillow is 20 by 26 inches. These regular-size pillows are ideal for smaller to mid-size beds. One standard pillow snuggly fits a twin or twin XL mattress, and two standard pillows, placed side-by-side, take up a full-size or queen-size bed. Since it takes three regular-sized pillows to cover a king-size mattress, they’re not the best choice for bigger beds. 

Standard pillows are great for people who like to sleep on their side, back, or stomach. They’re also ideal for children. However, people who move around while sleeping might find them too small and uncomfortable, slipping off them while they slumber. 

For pillowcases, use a standard size for a snug fit (queen and king-size pillowcases will hang loosely).

Super Standard Pillow Dimensions

The size of a super standard pillow is 20 by 28 inches. Two inches longer than a regular-size pillow, the super standard adds a bit of extra volume. They're a great option if you want a longer pillow than a standard but not as long as a queen. Like a regular pillow, one standard-size pillow fits twin and twin XL beds, while it takes two for a full or queen-size mattress. 

Super standard pillows are great for a combination sleeper who doesn't have a set sleeping style. However, the added length can help sleepers who toss and turn through the night. 

For pillowcases, a standard or super standard works well. Anything larger will have a looser fit. 

Queen Pillow Dimensions

The size of a queen pillow is 20 by 30 inches. True to their name, queen pillows are made to fit queen-size mattresses, and they do so more precisely than other larger pillows. Two fit nicely on a queen bed and are even big enough for a king mattress. One queen pillow also provides a fuller look for twin-size beds.

Queen pillows are ideal for restless sleepers that move around at night and need more surface space. Four inches longer than a standard pillow, they also offer an affordable choice for people who want a big pillow without paying king pillow prices.

For pillowcases, queen pillows fit snuggly in a standard-size pillowcase, so you don’t have to buy a bigger size unless you prefer a looser look. 

King Pillow Dimensions

The size of a king pillow is 20 by 36 inches. These pillows are 10 inches longer than a standard-size pillow and fit perfectly on a king mattress. The bigger size also makes them suitable for California king beds and split king mattresses. While you can put king pillows on smaller-sized beds, they may hang over the edges of your mattress in a more disheveled look. 

King pillows are great for adults with broad shoulders or people who have back issues and want extra support. 

For pillowcases, king pillows will not fit in standard-size pillowcases. You’ll have to buy  pillowcases that are clearly made for king pillows. 

Body Pillow Dimensions

The size of a body pillow is 20 by 54 inches. Because of their larger size, body pillows can only fit across queen and king-size mattresses. These pillows are typically used for health reasons and not for their stylistic nature. 

For example, pregnant women use a body pillow to help with back pressure and hip pain. Side sleepers may also use a body pillow to help prevent them from moving around in the night. Others find body pillows helpful in supporting their neck and spine. 

For pillowcases, body pillows will need their own specifically sized pillowcase.

How to Choose the Right Pillow Dimensions

There are a few things to consider when choosing the size of your pillows, including the following: 

  • Your mattress - Your mattress size will affect which type of pillows you select, depending on how full or minimalist you want your bed to appear when made. For example, perhaps you like a fuller look and opt for a queen pillow for a twin-size bed.
  • Your sleeping position - While a regular-size pillow with standard dimensions offers the most versatility to support a variety of sleeping positions, other pillows could suit a certain need. For instance, a wider pillow could provide more stability and support if you sleep on your side or toss and turn at night. 
  • Your bedroom’s style - The size of your pillows can also impact the aesthetics of your bedroom. Layering and stacking different shapes and sizes can create a certain look and feel. Understanding what vibe you’re trying to achieve will help you decide which size is best for your room.
  • Your budget - Larger pillows and pillowcases tend to be more expensive. If you're furnishing a bedroom that will get less use (like a guest bedroom), you may opt for standard-size pillows and pillowcases. That way, you can splurge on bigger ticket items for the bedrooms you use daily, like your primary suite.

  • How to Measure a Pillow

    While measuring a pillow is pretty straightforward, you'll want to be precise since incorrect dimensions can completely throw everything off. So here are a few standard steps to take: 

    1. Place your pillow on a flat surface, outside of its case. 
    1. Use a flexible measuring tape, like the kind a tailor or seamstress uses. 
    1. Measure the inside seams across the length and width of your pillow. Go along the bottom edges instead of the center for more precise measurements. 
    1. Note the exact measurements for your pillowcases and keep them documented for future reference. 

    Final Thoughts on Standard Pillow Dimensions

    The right pillow size can impact your comfort by supporting various sleeping positions. Pillow dimensions can also affect the aesthetics of your bedroom — a space where you spend time every night. By following this simple guide and investing in quality pillows and pillowcases, you’ll be able to get the beauty sleep you deserve.
