Mattress Size Guide

 Twin Mattress Size – 39″ x 75″

A Twin mattress is commonly found in children’s rooms, guest bedrooms, and some college dorm rooms. The twin size mattress dimensions are 39 inches wide by 75 inches long. It’s a great option for overnight guests and fits well in small spaces in general.


Twin XL Mattress Size – 39″ x 80″

The Twin XL mattress is the most common bed size in traditional college dorms. It’s called the “Twin XL” because it’s 5 inches longer than standard Twin mattresses. It’s 39 inches wide by 80 inches long. This size is perfect for tall adults with a small bedroom.


Full Mattress Size – 54″ x 75″

A Full mattress is an ideal option for a guest room or a teenager who has outgrown their kid bed. It’s 54 inches wide and 75 inches long, which is 15 inches wider than a Twin and 5 inches shorter than a Queen. This size is fit for someone who loves a balance of living space and sleeping space.


Queen Mattress Size – 60″ x 80″ 

The Queen mattress is the most popular size mattress. It’s 60 inches wide and 80 inches long, making it 6 inches wider and 5 inches longer than a Full-size bed. This is a great bed for two adults to sleep in a small Master Bedroom (at least 10 feet wide by 10 feet long) comfortably.


King Mattress Size – 76″ x 80″

The King mattress is the best option if you want a lot of sleeping space. It’s 76 inches wide by 80 inches long. It’s 16 inches wider than a queen, which is best for two people or one person with a dog. That’s over a foot wider!
