A standard queen mattress is 60 inches wide and 80 inches long. That equals 152.4 × 203.2 cm, or about 5 feet by 6 feet 8 inches.
It is the most popular bed size for a good reason. It fits most bedrooms and gives couples real space. This guide covers queen size mattress dimensions, how a queen compares with other sizes, and which frame and room you need.

Standard Queen Mattress Dimensions in Inches, Feet & CM
Here is the queen mattress size in every common unit:
| Unit | Width | Length |
|---|---|---|
| Inches | 60 | 80 |
| Feet | 5 ft | 6 ft 8 in (6.67 ft) |
| Centimeters | 152.4 | 203.2 |
| Millimeters | 1,524 | 2,032 |
| Meters | 1.52 | 2.03 |
Multiply 60 by 80 and you get 4,800 square inches. That is about 33 square feet of sleep surface, a figure Leesa also uses for floor space.
Two sleepers get about 30 inches of width each. That is the main limit of a queen.
Queen bed dimensions describe the mattress only, not the frame. Mattress thickness is separate. It runs from about 8 to 14 inches, and most beds sit between 10 and 11 inches, per Leesa.
Brands can differ by a small amount. Check the product page before you buy sheets or a frame.
Queen vs. Full, Twin, King & Other Mattress Sizes
This chart shows standard mattress sizes in the US, using Leesa’s measurements:
| Size | Inches (W × L) | Centimeters |
|---|---|---|
| Twin | 38 × 75 | 96.5 × 190.5 |
| Twin XL | 38 × 80 | 96.5 × 203.2 |
| Full | 53 × 75 | 134.6 × 190.5 |
| Queen | 60 × 80 | 152.4 × 203.2 |
| King | 76 × 80 | 193.0 × 203.2 |
| California King | 72 × 84 | 182.9 × 213.4 |
Is a queen mattress bigger than a full? Yes. It is 7 inches wider and 5 inches longer. Sources list a full at 53 or 54 inches wide, so the gap is 6 to 7 inches. SweetNight uses 54.
Just as choosing the right mattress depends on knowing its exact width and length, everyday items also come in standard sizes that are useful to understand. For another practical measurement guide, explore standard beverage can dimensions to compare can heights, diameters, and capacities in inches, millimeters, and centimeters.
Two sleepers on a full get about 26 inches each. A queen gives each of them about 30.
A queen and a king share the same 80-inch length. The king is 16 inches wider. A California king is 4 inches longer than a queen, so it suits very tall sleepers.
Queen Bed Frame Size & Room Space You Need
What size bed frame do you need for a queen mattress? A queen-size frame. Frames and mattresses are compatible across the industry.
The frame itself is wider than the mattress. With a headboard, side rails or a thick upholstered design, the full bed can be about 62 to 86 inches wide. Many headboards stand 48 to 60 inches tall.
Check the support type too. A platform bed, foundation or adjustable base works well. A box spring is not advised for foam or hybrid mattresses.
Room size for a queen bed:
- Minimum: 10 × 10 feet.
- Better: 12 × 12 feet (144 square feet).
- Walking space: about 2 feet on each side, says SweetNight.
A queen takes about 33 square feet. Leesa estimates a nightstand, dresser and clutter use roughly 23 more. That leaves about 85 square feet of open floor.
Two quick checks help. Outline the bed on the floor with painter’s tape. Then measure doorways, halls and stairs before delivery.
Buy queen sheets. If your mattress is thick, choose deep-pocket fitted sheets. Check the comforter size on the label.
Queen Size Variations: Olympic, California, Split & RV Queen
Not every queen is 60 × 80. These queen mattress sizes exist too, per Leesa:
| Type | Inches (W × L) | Best for |
|---|---|---|
| California Queen | 60 × 84 | Tall sleepers |
| Olympic Queen | 66 × 80 | Extra width, kids or pets |
| Split Queen | 30 × 80 (two beds) | Adjustable bases |
| RV / Short Queen | 60 × 75 | Campers and small spaces |
These sizes are harder to shop for. Frames and sheets are limited. Confirm that the mattress, frame and bedding match before you order.
Queen sizes can differ outside the US, so check the label if you buy from abroad.
