Mattress Size Guide: Twin, Full, Queen, King



Finding the right mattress can mean the difference between a good night's sleep and interrupted sleep that eventually leads to a lower quality of life. Simply put, finding the correct mattress size is just as essential to one's well being as finding a mattress with just the right amount of firmness and support. So if you're looking for a mattress for yourself, your child, or for you and your partner, here is a guide to help understand the differences in mattress sizes.

Twin Mattresses

The twin or single bed became popular in the 1890's as an alternative to the standard, couple sized beds. Its popularity amongst the younger generations during the Victorian age eventually led to its use in shared rooms with siblings and in college dorms. Nowadays, the twin mattress is customary for a child, residential housing, a guest room for one adult, or as a mattress for some day beds. Approximately 38 by 75 inches, the twin is the smallest mattress size other than the crib-sized mattress. The twin can also come extra long (approximately 38 by 80 inches).

Full Mattresses

A full mattress, also known as a double mattress, is 53 by 75 inches. It's ideal for a growing child or teenager, or for one adult. Although obviously larger than a twin, it's still recommended for one person. That's because a full mattress is only about 15 inches wider than a twin, leaving just 27 inches or so of personal space for each person if two individuals occupied the bed.

So if you're on the market for a mattress for one person, here are some points you should consider:

  • If you're looking to save space in a dormitory or spare room, or to furnish a shared bedroom for siblings, you'll want a twin.
  • If you're looking for a bed for a growing child or teenager, or for one adult, a full size mattress offers a little more room for larger bodies.
  • Depending upon the brand, the length and/or width of twins and full size mattresses can vary by an inch.
  • Finally, even though a full size mattress is also known as a double bed, it's not usually considered wide enough for two people to sleep comfortably.

Queen vs. King Mattresses

It should go without saying that of course a king size bed is going to be larger than a queen, but how much larger, and do you need it? First of all, it's important to note that both queen and king sized beds are the same length. Both measure at 80 inches, and both require a center support to keep the bed from sagging in the middle. This means the only real difference is the width.

Queen Mattresses

Queen sized beds have a width of 60 inches, which makes them great for a single person who is particularly tall, or couples who are comfortable getting close to one another. Smaller people won't have much trouble resting beside each other comfortably however. Queen sized beds are a great choice for guest rooms, and smaller master bedrooms.

King Mattresses

King sized beds measure in at 76 inches wide. Because of their increased size, king sized beds typically are reserved for master bedrooms, though if you have the floor space they make great accommodations for guests as well. Their width is also ideal for couples who are taller or that occupy more space on the bed. The last difference is of course cost, a king is going to cost more than a queen. Due to the wide variety in mattress construction and manufacturing costs, it's difficult to say what the exact difference is going to be.
