The Ultimate Mattress Sizing Guide

According to some research, about 50 to 70 million Americans suffer from sleep issues.

If you are suffering from sleep issues, the cause might be the size of your mattress. 

Thankfully, we have the perfect mattress sizing guide to help you figure out what size would be perfect to get a good night’s rest, so make sure you keep reading!

Crib Mattress

If you have a child, you may want to buy a crib mattress so they don’t have too much room to roll around. 

These mattresses are normally about 27 by 52 inches. They’re best for toddlers and babies. They’re also designed to fit into any standard crib.

You can find innerspring mattresses, but you can also buy foam ones. These are normally a little bit firmer to make sure the baby is safe. 

Twin Size Mattress

Twin size mattresses are great for children or teenagers. These mattresses are about 39 by 75 inches. 

They’re also a popular option for adults who are living in a small apartment or home and don’t have much space. A regular twin will be comfortable for most adult men or women, but you may want to upgrade to a twin XL.

Twin XL Size Mattress

A Twin XL is about 39 and 80 inches. It’s a little bit longer, and it’s normally made for college dorms.

However, it can be great for children or teenagers that are taller. If you’re an adult sleeping alone, this should be enough space to fit one person. 

These mattresses aren’t widely available as other sizes, but you’ll still be able to find a lot of options for sheets and toppers.

Full-Size Mattress

A full-size mattress is something that’s in the middle between a twin and a queen.

It was popular during the ’60s and ’70s. It was popular for married couples when bedrooms were a lot smaller, but they’re only about fifteen inches wider than your average twin bed. 

If you and your partner are both small and have a small bedroom, this bed may be the best option. The sheets are also cheaper as well!

Queen Size Mattress

The queen mattress is the most popular out of all of the options out there. It became popular in the 80’s when people realized the full wasn’t enough to share with someone else.

This bed is sixty by eight inches, and the extra six inches in width and length from a double make it better to have a sleeping environment that won’t be disturbed. 

Many people choose a queen size bed because it fits well into a lot of bedrooms, and it’s also enough space for most couples. 

King Size Mattress

If you’re one of those couples who doesn’t want to be touching your partner at all, you should get a king-sized mattress. This mattress has recently started becoming popular, and they actually come in two different sizes.

They’re a standard king and a California King. If you’re really tall, you’ll want to get the California King because it’ll be 76 by 80 inches. A standard king is 72 by 80 inches.

However, the downside of these beds is that they can be difficult to maneuver and transport. Sheets and toppers are also more expensive for this kind of mattress. 

Before you buy one, make sure that you measure your bedroom to ensure that it will fit. You’ll need a bedroom that is at least ten to twelve feet, but it’ll still feel tight in there. 

Factors to Consider

Now that you know the different sizes to choose from, you’ll have to decide which one to get.

When making a decision, there are a few factors you’ll want to consider.

Number of Sleepers

For example, how many people are you going to be sharing a bed with? If it’s just you and your partner, a queen would be best.

But if you’re going to be sharing with a child or a pet, you’ll definitely need a king. 


You should set a budget before you start looking at different mattresses. 

A new quality mattress could cost anywhere from $400 to $3,000. The size of the mattress will be the biggest factor, but it’ll also depend on what kind of mattress you want to get.

Keep in mind that you’ll also need to set a budget for blankets, sheets, and other accessories, like a frame.

Room Size

If you’re planning to stay in one house for a while, you’ll have confidence in picking the right size.

But if you’re moving, you may want to figure out if a king would fit in the next room. Most rooms are built to hold at least a queen, so might be the safest option. 

Sleep Position

How do you sleep each night? Do you lay on your side or on your back?

If you’re experiencing pain, you’ll want to find the best mattress for pressure relief. But you’ll also want to consider how much room you need. For example, if you like to spread out and not touch your partner, you should get a king. 

If you sleep curled up, you’re probably okay with a queen size.
