Pillows are a very important part of your sleep health, and having a good pillow to pair with your mattress is vital. In this pillow size guide we will go over everything from pillow dimensions to pillow cases.

One could easily assume that matching a pillow to a mattress is simple business, but everything can vary when you are talking aesthetics, economics and feel. If you are in the market for a new pillow, make sure to keep reading!

How to Choose the Right Pillow Size

Finding the right sized pillow can be hard, but sometimes it can make all the difference in the quality of sleep you get. In this section we’ll list a few things to look for when shopping.

  • Support. It is important to find a pillow that will support your head all night, so if you are a restless sleeper you might want to buy a bigger pillow.
  • Aesthetics. If you care about style, it’s often beneficial to consider the size of your mattress and pillows.
  • Budget. Buying smaller pillows just because they are cheaper might be a mistake you are forced to live with for a long time. It is often beneficial to pay for a better pillow because they will hold up longer and generally improve your sleep.

Standard Size Pillow

A standard size pillow is the smallest of the most common bed pillows offered for sleeping (though there are smaller decorative pillows). They are solid options for sleepers who don’t shift sleeping positions at night.

Standard Pillow Dimensions

The standard pillow is 20 inches x 26 inches. This pillow fits nicely on a twin size bed, and two can fit comfortably across a full or even a queen size mattress. That said, to fill out a king or California king, you will need three standard size pillows.

Sleeping Position

The standard pillow is a comfortable and suitable option for all of the major sleeping positions, but it is simply too small for restless sleepers. If you change sleeping positions, you might find yourself sliding off the side and waking up with neck pain because your head isn’t supported.
