After you've found your perfect mattress, you next will need to find your perfect pillows to go with it. 

Pillows help to complete the feel and look of your bed. They help to improve your sleep and provide you with the right balance of support and comfort for your neck and head region. 

Bed pillows come in various sizes that suit various needs. Choosing the right size for you is a personal choice. It's not as easy as matching the pillow to the size of your mattress. 

In this article, your pillow specialist at Polysleep helps you understand the different sizes of bed pillows and why they matter.

Bed pillow sizes chart

You can broadly categorize bed pillow sizes under Body, King, Queen and Standard. But there might be certain pillow sub-categories too with minor differences in dimensions to look out for.

Pillow Size Measurements (inch) Measurements (cm)
Body 20 × 54  51 × 137 
King 20 × 36  51 × 92 
Queen 20 × 30 51 × 76 
Standard 20 × 26  51 × 56

Body pillow size

Body pillows measure 20 x 54 inches and are ideal for people who sleep on their side. They curve to fit your body's shape and provide adequate support when you sleep on your side.

Body pillows are great for pregnant women who like to use them under their bodies while sleeping on their sides. This helps keep them from rolling onto their backs or stomachs. 

Sleeping on your side is believed to be the best sleep position when you're pregnant.

Queen pillow size

Queen pillows are 20 x 30 inches, but there might be a slight variation in the dimensions, depending on the brands. 

A Queen's extra length compared to a standard is beneficial for restless sleepers.

Queen size pillows fit snug in standard pillowcases. Certain bedding manufacturers might offer other sizes, but popular pillowcase sizes are standard and king.

King pillow size

King pillows are 20 x 36 inches, but they might differ depending on the brands too. 

They are long and are convenient for sleepers who tend to be active in their sleep and toss and turn.

You could also use King pillows to support your back when you're sitting up in bed binge-watching TV or reading. The extra length will come in handy for improved lumbar support.

King size pillows are ideal with King pillowcases that measure 20 to 21 inches by 36 to 41 inches.

Standard pillow size

Standard pillows measure 20 x 26 inches. They're a compact size ideal for people who don't switch sleep positions throughout the night.

If you're a combination sleeper who tends to do a lot of tossing and turning in bed while you sleep, you might slide off your pillow, which can cause neck aches.

But, if you tend to sleep on your back, stomach or side, a standard size might be ideal for you.

A standard size pillow will fit comfortably across a twin bed, while you can place two across on a full and a queen bed. But, to cover a King's or California King's width, you'll require three standard pillows.

Certain bedding companies also have a super standard subcategory that measures 20 x 28 inches. The width is the same, but you obtain an added 2 inches in length. 

Because it's a minor difference, both pillow sizes can fit into a regular standard pillowcase that measures 20 to 21 inches by 30 to 32 inches.

The Polysleep pillow size

You can adjust The Polysleep pillow from 2 inches up to 9 inches in height, depending on how many layers you use. The measurements and dimensions are as follows:

Standard King
19 × 26 inches — 5.5 lbs 34 × 19 inches — 7.7 lbs

Why does pillow size matter?

Most individuals like to sleep all night on their pillow, but if you sleep on the wrong pillow size, you may sleep off during the nighttime.

The proper pillow functions as the ideal support for your head and cradles your shoulders or neck while you're sleeping. You require this support for:

  • Preventing neck ache
  • Maintaining health spinal alignment
  • Preventing upper back pain

Furthermore, you could also mix and match different-sized and colorful pillows to make your bed appear vibrant.

Throw pillow size for your bed?

Throw pillows on a bed

Throw pillows can help to elevate the design of your bed. They come in various shapes, colors, sizes and textures to accommodate your bedroom's design. 

Decorative throw pillows can also be used on chairs and sofas. 

While most throw pillows don't support your head and neck, they can be placed between your knees to ease hip pain. 

Various sizes of throw pillows include:

  • 26x26 inches
  • 20x20 inches
  • 16x26 inches

Bigger size throw pillows are ideal for bigger beds.

When layering your throw pillows on your bed, you'll want to layer the bigger throw pillows at the back and the smaller ones in front, decreasing the number of pillows in every layer. 

For instance, you could have two or four King size pillows in the back, and then you layer three throw pillows in front of those and one smaller rectangular pillow to complete it.

Our tips to choose the right bed pillow cover

Chances are you've put a lot of thought into your pillows. But have you considered your bed pillow covers? These are important because they protect your pillows.

Here are some tips to choose the right pillow cover.

Like with sheets, pillow covers are crafted from various types of fabrics both synthetic and natural. Their fabrics are an important factor in determining your new pillow cover's longevity and comfort. 

For the best possible option that provides both lasting softness and outstanding sleep, you'll want to choose a high-quality and all-natural fabric.

Once you've decided on your bed pillow cover's fabric, next is the size. 

Of course, it should match the size of your pillows. 

Standard size bed pillow covers are 20 x 26, but there are other sizes.

Next, you'll want to decide on which type of bed pillow cover you want. 

Regular pillow cases have openings on one side. 

Shams typically have extra fabric around all four sides and the opening is in the back.
