Full vs Queen Mattress: Size Difference, Couples, Room Size, Price and How to Choose

Full and queen mattresses are two of the most popular sizes in the country, and they look close on a size chart. In real life, the gap between them is big enough to change how two people sleep, how a room feels and how much you pay. Pick the full when you need a queen and you will feel cramped every night. Pick a queen for a tiny room and you may lose your floor.

This article is part of our bed sizes chart, where you can compare related options.

A full mattress, also called a double, is about 54 inches wide and 75 inches long. A queen is about 60 inches wide and 80 inches long. That makes the queen 6 inches wider and 5 inches longer. This guide compares the two sizes, explains who should choose which, covers room size, price, bedding and frames, and gives a simple way to decide.

Size Comparison

The full at 54 by 75 inches. One source gives the width as 53 inches, so exact figures vary a little by brand. One vendor claims every full mattress sold in the US is exactly the same size, but treat that cautiously and check the label.

The queen has about 750 more square inches of sleep surface. For a single sleeper, that is a lot of extra room. For two people, it is the difference between tight and comfortable.

Per-Person Space

A full bed gives two adults about 27 inches of width each. That is less than a crib mattress (about 28 inches). A queen gives each person about 30 inches. A king gives about 38 inches each. If you like to sprawl, stretch or sleep with pets, those inches matter.

Who Should Choose a Full?

Key points: single sleepers who want more room than a twin; teens who have outgrown a twin; guest rooms and small bedrooms; tight budgets. A full mattress is typically cheaper than a queen, and so is the bedding; short-term setups like first apartments; couples who like to snuggle and do not mind close quarters.

Zoma’s comparison rates a full as cramped for two adults. If you share a bed, test it before you commit.

Who Should Choose a Queen?

Couples. Sleep Foundation’s guidance is that queens are best suited for couples, parents sharing with children and taller people. Taller sleepers. The extra 5 inches of length helps people over about 6 feet tall. Single sleepers who like to spread out. Master bedrooms with enough floor space. Anyone with pets who share the bed.

Some couples find even a queen tight and move up to a king. Puffy notes that people who prefer more personal sleeping space may struggle on a queen. See the how to choose a mattress guide and the Alaskan king guide for larger sizes.

Room Size

Recommendations differ by retailer.

One retailer suggests a room of about 10 by 12 feet for a full and 10 by 14 feet for a queen. Another lists 10 by 10 feet as the minimum for a queen. Casper says queens typically work best in medium to large bedrooms.

These are rough guides. The real test is what fits with the frame, nightstands and walking space. Leave at least two feet of space around the bed if possible. Tape the bed outline on the floor to see how it feels.

A full bed leaves more floor in a small room. That can matter for a desk, a dresser or a reading chair. See the small desk and small dresser guides for small-space ideas.

Price and Bedding

A full-size mattress is typically cheaper than a queen. Sheets, comforters, toppers and protectors are also usually less expensive and widely available in both sizes. Queen bedding is the most common size in stores, so you will have more choices. Full bedding is easy to find too, but sometimes in fewer styles.

Remember to price the whole setup: mattress, frame, foundation, bedding, protector and delivery. See the mattress cover, fitted sheet and mattress topper guides.

Frames and Bases

Make sure the frame matches the mattress. A full frame will not hold a queen mattress. Platform beds, bed frames and headboards come in both sizes. If you plan to upgrade later from a full to a queen, you will need a new frame, headboard and bedding. See the headboard queen guide and the upholstered bed frame guide.

Full vs Queen at a Glance

Special Cases

Tall sleepers: a full is 75 inches long, which is tight for anyone over about 6 feet. A queen is 80 inches. A twin XL is also 80 inches long but narrower. See the twin vs twin XL guide. Kids’ rooms: a full lasts longer than a twin, but a queen may be too big for a small room. College dorms: many are twin XL only. Check the school’s rules. Guest rooms: a queen is more comfortable for couples. A full works for single guests. RVs and boats: check the specific size, because some use short queens or other variations. Hot sleepers: more space means more room to move and stay cool.

Mattress Types

Both sizes come in all mattress types: memory foam, hybrid, innerspring and latex. See the memory foam, hybrid mattress and how to choose a mattress guides. The bigger the mattress, the heavier it is, so a queen can be harder to move or flip. Foam and hybrid beds that ship in a box can be easier to bring into a small apartment.

How to Decide

Count the sleepers. Two adults usually want a queen. Measure the room. Include the frame, nightstands and walking space. Check the tallest sleeper’s height. Think about pets and kids who share the bed. Set a budget for the mattress and bedding. Think about the future. Will you move to a bigger room? Test it in a store, if you can, or use a home trial.

If you are between sizes, a queen is the safer choice for most adults, as long as the room can handle it.

What mistakes should you avoid?

A few common mistakes are worth avoiding: choosing a full for two adults (and then regretting the lack of space); buying a queen for a room that cannot fit it; forgetting about the frame and bedding; ignoring height (a full may be short for tall people); not checking the actual dimensions (they vary slightly); skipping a trial period.
