Size Guide

Which mattress size is right for you?

When picking your next mattress, it’s more than just personal preference—two key things to keep in mind are how much room you have and who’s sleeping in the bed.

King Dimensions 76"x80", California King Dimensions 72"x84"

Upgrading to a King mattress is a game-changer if you’re sharing space with kids or pets. And if you’re tall, the extra length of a California King could be just right.

Full Dimensions 53"x75", Queen Dimensions 60"x80"

A Full size mattress is ideal for young adults or those with a smaller bedroom, while a Queen is the top pick for couples or anyone who enjoys extra space to sprawl out.

Twin Dimensions 38"x75", Twin XL Dimensions 38"x80"

The Twin is the smallest option, ideal for single sleepers. While the Twin XL is a dorm favorite it can also create a Split King if you purchase two.

Which pillow size is right for you?

Standard vs King Pillow Sizing
Pillow sizes can vary, but standard pillows, also known as queen pillows, are typically suitable for all types of sleepers. If you prefer extra space or need to fill the width of a larger mattress, king-size pillows, which are about 30% larger, are a great choice.

Upgraded edge support.

Added edge support makes it easier to get in and out of bed, and gives you more surface for sleeping.

An image of a person lying on her side on the Casper Cloud One mattress with her head on a pillow. A visual diagram placed on top of the mattress in the image shows indentations on the top layer of the mattress under her shoulders and hips, while the layer of foam underneath that remains fully supportive to help maintain spinal alignment.

Enhanced pressure relief.

Thicker layers of premium foam better cradle your body for a boost of soothing comfort.
