Spine Support
A King mattress is 16 inches wider than a Queen (76" vs 60") but exactly the same length (80"). That extra width gives each partner the sleeping width of a Twin bed, which is why the King is the top pick for couples who want real space. The Queen is still the most popular of all mattress sizes in the US, because it fits most bedrooms, costs noticeably less, and still sleeps two adults comfortably.
The short version: if your bedroom is at least 12 x 12 feet and you share the bed every night, go King. If your room is closer to 10 x 10 feet, or you share with a partner who sleeps still, the Queen is the smarter buy. This guide breaks down the dimensions, price, room fit, and bedding differences so you can decide with confidence.
Queen vs King at a Glance
The two sizes share the same 80-inch length. Everything else, from sleeping space per person to the room you need, comes down to that 16-inch difference in width.

What Is a Queen Size Mattress?
A standard Queen mattress measures 60 inches wide by 80 inches long (about 152 x 203 cm). Shared between two people, that is 30 inches of personal sleeping space each: 3 inches more per person than a Full, and 8 inches less than a King.
The Queen is the best-selling mattress size in the US because it balances space, price, and room fit better than any other size. It is long enough for sleepers up to about 6'2", and it works with the widest range of frames, sheets, and bedroom furniture.
Pros
- Fits a 10 x 10 foot bedroom with walking space on both sides
- Lower price for the mattress, frame, and every piece of bedding
- Easier to move through narrow doorways and staircases
- The widest choice of sheets, duvets, and headboards
Cons
- 30 inches per person can feel tight for two adults
- Little room for kids or pets to join the bed
- Restless sleepers are more likely to disturb each other

What Is a King Size Mattress?
A standard King mattress, sometimes called an Eastern King, measures 76 inches wide by 80 inches long (about 193 x 203 cm). It is the widest standard mattress size, giving each person 38 inches of sleeping space when shared, the same width as a Twin bed each.
The King is not longer than a Queen, only wider. If you are over about 6'4" and need extra length, a California King (72" x 84") is the better fit. We cover that trade-off in King vs California King.
Pros
- 38 inches per person, so each partner barely feels the other move
- Room for a child or a pet to join without crowding
- Space to spread out for side, stomach, and combination sleepers
- Comfortable for reading, working, or watching TV in bed
Cons
- Needs a bedroom of at least 12 x 12 feet
- Costs more for the mattress, frame, and bedding
- Heavier and harder to move once it is set up
Price and Value
On BedStory, a King usually costs about 30% more than the same mattress in Queen. The exact gap depends on the model and height you choose, so compare the same mattress in both sizes before you decide.
The mattress is only part of the cost. Moving up to a King also means:
- A wider bed frame or platform, which usually needs a center support leg
- King-size fitted sheets, flat sheets, a duvet, and a mattress protector
- King pillows, or three Standard pillows across the headboard
- Often, wider nightstands or a new headboard to match the bed
Delivery is not part of the difference. Every BedStory mattress ships free, compressed in a box, in every size.
Which Size Fits Your Bedroom?
Room size usually decides this before personal preference does. Plan for at least 24 inches of walking space on each side of the bed and 36 inches at the foot, plus room for nightstands and any closet or bedroom doors that swing into the space.
Minimum room size
- Queen: 10 x 10 feet. Fits nightstands on both sides with basic walking space.
- King: 12 x 12 feet. Needed for comfortable walking space and matching nightstands.
Ideal room size
- Queen: 10 x 12 feet or larger, which leaves room for a dresser or a bench at the foot.
- King: 13 x 13 feet or larger, which fits a full bedroom set without feeling crowded.
If your bedroom is smaller than 10 x 10 feet, a Full is the better fit. If you can only keep one side of the bed clear, choose a Queen even if the room looks big enough for a King.
Who Should Choose a Queen?
A Queen is the right call if any of these describe you:
- You sleep alone and want room to spread out without filling the whole room
- You share with a partner who sleeps still and stays on their own side
- Your bedroom is around 10 x 10 or 10 x 12 feet
- You rent or move often and need a bed that fits through tight spaces
- You want the lowest total cost for the mattress, frame, and bedding
- You are furnishing a guest room
Who Should Choose a King?
Upgrade to a King if any of these apply:
- You share the bed and one of you tosses, kicks, or sprawls
- Children or pets often join the bed at night or on weekend mornings
- Either of you is broad-shouldered or changes position a lot through the night
- Your bedroom is 12 x 12 feet or larger
- You like to read, work, or watch TV in bed
Sheets, Frames, and Accessories
The size you choose also decides what goes on and around the mattress.
- Sheets: Queen and King fitted sheets are not interchangeable. BedStory mattresses are 12" to 14" thick, so look for fitted sheets with pockets of at least 15".
- Comforters and duvets: a King comforter hangs too low on a Queen, and a Queen comforter leaves the sides of a King exposed. Match the bedding to the bed.
- Pillows: a Queen fits two Standard or Queen pillows side by side. A King fits two King pillows or three Standard pillows.
- Bed frames: both sizes work on platform, slatted, and upholstered frames. BedStory mattresses are not recommended for adjustable bed bases.
- Mattress protector: the cost rises with size, so include one in your budget.
If you are upgrading from a Queen to a King, plan to replace your sheets, duvet, frame, and often your nightstands as well.
Queen or King? Our Verdict
Choose a Queen if your room is around 10 x 10 feet, your budget is tight, or you share with a still sleeper. Choose a King if you share the bed every night, your room is 12 x 12 feet or larger, and you want the biggest improvement in sleeping space a mattress size can give.

Frequently Asked Questions
Can two adults sleep comfortably on a Queen?
Yes, if both partners are average-sized and tend to stay on their own side. A Queen gives each sleeper 30 inches, which is enough for still sleepers but tight for anyone who sprawls or shares the bed with kids or a dog.
Is a King worth the extra cost?
If you have the room and share the bed every night, yes. Each sleeper gets 38 inches instead of 30, which is the biggest improvement in personal space you can get from a mattress size. For solo sleepers and guest rooms, the money is better spent on a higher-quality Queen.
Will a King fit in a 10 x 10 foot room?
It will fit, but only just. A King leaves about 22 inches on each side in a 10 x 10 room, which is less than the recommended 24 inches of walking space. If you want nightstands or other furniture, a Queen is the better choice.
Is a King longer than a Queen?
No. Both are 80 inches long. A King is only wider. If you need more length, a California King is 84 inches long.
Do I need a special bed frame for a King?
You need a King-size frame, ideally with a center support leg to keep the mattress evenly supported. Platform, slatted, and upholstered King frames all work with a BedStory mattress. Adjustable bases are not recommended.
