King vs Queen Bed
Updated November 11, 2026 · By Serge, King Size Bed
King vs queen bed: a king is 76 x 80 inches and a queen is 60 x 80, so the king is 16 inches wider, the same length, and gives 27% more sleeping surface. The same bed model costs a median of $100 more in king size (22.5%), based on 502 beds sold in both.

Thirty inches each on a queen is narrower than a twin mattress, which is 38 inches wide. On a king, each person gets 38 inches: exactly the width of a twin XL.
The industry guideline behind these sizes (International Sleep Products Association) lists both at 79.5 inches long; labels round the length to 80.
King and queen size in feet and centimeters: 6 ft 4 in against 5 ft
A king mattress is 6 feet 4 inches wide and 6 feet 8 inches long (193 x 203 cm); a queen is 5 feet wide and the same 6 feet 8 inches long (152 x 203 cm). The king is 1 foot 4 inches wider, and neither is longer than the other.
| Inches | Feet | Centimeters | |
|---|---|---|---|
| King width | 76 in | 6 ft 4 in | 193 cm |
| Queen width | 60 in | 5 ft | 152 cm |
| Length, both sizes | 80 in | 6 ft 8 in | 203 cm |
| Difference in width | 16 in | 1 ft 4 in | 41 cm |

These are mattress sizes. A frame adds its own border: the median king frame we read was 80.7 inches wide outside, about 6 feet 9 inches, so plan the wall for the frame, not the mattress.
In Europe the names shift: the bed sold as a king in France is 180 x 200 cm, 5.1 in narrower than a US king. Our US vs European bed sizes chart lines the two systems up.
How big is a king size bed?
A standard king size bed is 76 inches wide and 80 inches long: 6 feet 4 inches by 6 feet 8 inches, or 193 x 203 cm, about 42.2 square feet of mattress. The frame around it is bigger: the median king frame sold online in the US measures about 80 x 86 inches, and the king size bed frames we sell run from 76 to 105 inches wide, up to 137 inches for a bed with built-in nightstands.
| King-family size | Mattress | Feet | Centimeters | Against a standard king |
|---|---|---|---|---|
| King (also called Eastern king) | 76 x 80 in | 6 ft 4 in x 6 ft 8 in | 193 x 203 cm | reference size |
| Split king | two halves of 38 x 80 in | two of 3 ft 2 in x 6 ft 8 in | two of 97 x 203 cm | same overall size, two twin XL mattresses |
| California king | 72 x 84 in | 6 ft x 7 ft | 183 x 213 cm | 4 in narrower, 4 in longer |
| Texas king | 80 x 98 in | 6 ft 8 in x 8 ft 2 in | 203 x 249 cm | 4 in wider, 18 in longer |
| Alaskan king | 108 x 108 in | 9 ft x 9 ft | 274 x 274 cm | 32 in wider, 28 in longer |

The king, the split king and the California king are the standard US sizes; the Texas and Alaskan kings are not, so their mattresses, frames and sheets are harder to find. For the king next to every smaller size, frames included, see our chart of mattress sizes.
Price difference between a queen and a king bed
To measure the price difference between a queen and a king bed, we compared 502 bed models sold in both queen and king by US furniture stores (September 2026). The king was more expensive in 98% of them. The median gap was $100, and for the middle half of the models it ran from $74 to $138, or 16% to 31% more than the queen.
Check the bedding too: if the sheet or comforter set you like comes in both sizes, compare its queen and king price. You buy the bed once; you replace bedding several times.
Room size: the width is what changes
Both beds are the same length, so the question is only the wall. A king frame is usually around 80 inches wide outside (median of 545 king frames we read), so it needs about 16 inches more wall than a queen with a similar frame. With the headboard on a 12-foot wall, a median king frame leaves 32 inches on each side, enough for small nightstands. On a 10-foot wall it leaves 20 inches each side, and a queen becomes the easier choice.
Our king size bed dimensions guide has the full room table and a fit calculator, and our queen size bed dimensions guide has the same figures for a queen. To check your own room, use our king bed room calculator.
Disadvantages of a king bed
- It costs more. The same model cost a median of $100 more in king than in queen (502 models compared), and 16% to 31% more for the middle half of them.
- It needs more wall. Count about 16 inches more than a queen with a similar frame. On a 10-foot wall, a median king frame leaves 20 inches on each side, too little for standard nightstands.
- It is bigger to carry in. The mattress is 76 inches wide, 16 more than a queen: measure stairs and doorways if it is not delivered compressed in a box.
Is a king bed too big for one person?
Not in itself: one sleeper gets 76 inches of width, twice a twin XL. The limit is the room. With the headboard on a 12-foot wall, a median king frame leaves 32 inches on each side; on a 10-foot wall, only 20 inches. If your headboard wall is 10 feet or less, a queen is the better fit for one sleeper.
Which one should you buy?
- Two adults who wake each other up, or a child or dog who ends up in the bed: king. The 8 extra inches per person are the whole point.
- One sleeper, or a room where the only wall for the headboard is 10 feet or less: queen. You keep the walkway and save around $100 on the bed.
- Tall sleepers: both beds are 80 inches long. A California king adds 4 inches of length (84 in) but is 4 inches narrower than a king: see our king vs California king guide.
- Couples with different firmness preferences: a split king, two twin XL mattresses on one king frame.
If the choice is really between a queen and the size below it, our full vs queen bed guide sets the 60 x 80 inch queen against the 54 x 75 inch full.
King vs queen: frames, headboards and bedding
The mattress is 16 inches wider in king, and the things around it grow with it. The figures below come from our other guides: US store listings and bedding size charts read in September and October 2026.
| King | Queen | |
|---|---|---|
| Median frame, outside size (one store's listings) | 80.7 x 87 in (309 models) | 64.5 x 87 in (265 models) |
| Headboard width, at least | 76 in (80.7 in with the frame, at the median) | 60 in (64.5 in with the frame) |
| Fitted sheet | 76 or 78 x 80 in | 60 x 80 in |
| Pillows across the bed | two king pillows, 20 x 36 in | two queen pillows, 20 x 30 in |

A queen headboard does not move up to a king: it is 16 inches too narrow for the mattress, and its bolt holes sit about 16 inches closer together than a king frame's, so it has to go on the wall or on adapter brackets. Details are in our headboard sizes chart; sheet and comforter sizes are in our king size bedding dimensions guide, and pillow sizes in our pillow sizes guide.
King beds to compare in your room
If the king fits your wall, compare frames by their outside size, listed on every product page: start with all king bed frames, or narrow it down.
- Tight room or low window: low profile king beds and king platform beds
- Giving up a dresser for the bigger bed: king beds with storage
- Tall sleepers who need 84 inches of length: California king bed frames
Full measurements, frame sizes and room sizes are in our king size bed dimensions guide. Settled on a king? Every one of our king bed frames lists its outside size, plus its slat spacing and weight capacity whenever the maker publishes them.
Prefer to browse by style first (upholstered, platform, wood or tall headboard)? Start from our king size bed shop.
Moving up from a queen to a king changes the wall space you need, not the nightstand height, which follows the mattress top.
Once the size is settled, our king bed cost guide adds the mattress, bedding, delivery and sales tax to the price of the frame.
King vs queen questions
How much bigger is a king than a queen?
16 inches wider and the same length: 76 x 80 against 60 x 80 inches, which is 27% more surface.
Which bed size is better, king or queen?
For two adults, a king: each gets 38 inches of width instead of 30. For one person or a narrow room, a queen.
Do most couples sleep on a king or queen bed?
We have not found an official count of this, so we will not guess. What we can measure is the cost: going from queen to king adds a median of $100 to the same bed.
Is a king bed worth the extra cost?
If two people share it every night, usually yes: $100 more for 27% more space. If one person sleeps alone most nights, the queen is the better use of the money.
Is a king bed the same as two queens?
No. Two queens side by side would be 120 inches wide. A king is the width of two twin XL mattresses, 2 x 38 inches.
Will king sheets fit a queen?
They will go on, but loosely: a king fitted sheet is 16 inches too wide for a queen and will bunch up.
