If you are wondering how many feet a queen size mattress is, a standard queen mattress measures approximately 5 feet wide by 6 feet 8 inches long.
The standard queen mattress dimensions are:
- Width: 60 inches = 5 feet
- Length: 80 inches = 6 feet 8 inches
- Surface area: approximately 33.33 square feet
So, a standard queen size mattress is 5 feet wide and 6 feet 8 inches long.
Queen mattresses are one of the most popular mattress sizes because they provide a good balance between sleeping space and bedroom space. They are large enough for two adults while generally taking up less room than a king-size mattress.
Quick Answer: How Many Feet Is a Queen Size Mattress?
A standard queen mattress is:
5 feet wide × 6 feet 8 inches long
In decimal feet, the dimensions are approximately:
5 feet × 6.67 feet
The calculation for the length is:
80 inches ÷ 12 = 6.67 feet
Therefore:
60 inches = 5 feet
and:
80 inches = 6 feet 8 inches
What Are the Standard Queen Mattress Dimensions?
The standard queen mattress dimensions in the United States are:
| Measurement | Inches | Feet |
|---|---|---|
| Width | 60 inches | 5 feet |
| Length | 80 inches | 6 ft 8 in |
| Width in decimal feet | 60 inches | 5 ft |
| Length in decimal feet | 80 inches | 6.67 ft |
| Surface area | 4,800 sq in | 33.33 sq ft |
These dimensions refer to the mattress itself. The actual size of a bed frame can be slightly larger.
How Many Feet Long Is a Queen Mattress?
A standard queen mattress is 80 inches long.
To convert inches to feet:
80 ÷ 12 = 6.67 feet
Since 0.67 of a foot is approximately 8 inches:
A queen mattress is 6 feet 8 inches long.
This makes a queen mattress 6 feet 8 inches from one end to the other.
How Many Feet Wide Is a Queen Mattress?
A standard queen mattress is 60 inches wide.
Convert inches to feet:
60 ÷ 12 = 5 feet
Therefore:
A queen mattress is 5 feet wide.
The standard dimensions are therefore:
5 feet wide × 6 feet 8 inches long
How Many Square Feet Is a Queen Mattress?
To calculate the surface area, multiply the width by the length in feet.
A queen mattress is:
5 feet × 6.667 feet
Therefore:
5 × 6.667 ≈ 33.33 square feet
So, a standard queen mattress has approximately:
33.33 square feet of surface area
The exact calculation using inches is:
60 × 80 = 4,800 square inches
Since:
144 square inches = 1 square foot
Then:
4,800 ÷ 144 = 33.33 square feet
How Many Inches Is a Queen Size Mattress?
A standard queen mattress measures:
60 inches × 80 inches
That means it is:
- 60 inches wide
- 80 inches long
These dimensions are the standard queen mattress measurements in the United States.
How Many Feet Is a Queen Mattress Compared With a King?
A standard king mattress measures approximately 76 inches wide × 80 inches long.
In feet:
- Queen: 5 ft × 6 ft 8 in
- King: 6 ft 4 in × 6 ft 8 in
Both mattresses have the same standard length of 80 inches.
The primary difference is width.
A queen is:
60 inches wide
A king is:
76 inches wide
Difference:
76 − 60 = 16 inches
So, a standard king mattress is 16 inches wider than a queen mattress.
Queen vs. Full vs. King Mattress Dimensions
Comparing common mattress sizes makes it easier to understand the size of a queen mattress.
| Mattress Size | Width | Length | Approx. Size in Feet |
|---|---|---|---|
| Twin | 38 in | 75 in | 3 ft 2 in × 6 ft 3 in |
| Twin XL | 38 in | 80 in | 3 ft 2 in × 6 ft 8 in |
| Full | 54 in | 75 in | 4 ft 6 in × 6 ft 3 in |
| Queen | 60 in | 80 in | 5 ft × 6 ft 8 in |
| King | 76 in | 80 in | 6 ft 4 in × 6 ft 8 in |
| California King | 72 in | 84 in | 6 ft × 7 ft |
The queen mattress is wider than a full but narrower than a king.
How Big Is a Queen Mattress in Feet?
A queen mattress occupies approximately:
5 feet × 6.67 feet
of floor space before considering the bed frame.
Its surface area is approximately:
33.33 square feet
This makes it a practical choice for many primary bedrooms, guest rooms, and larger apartments.
Can Two Adults Sleep Comfortably on a Queen Mattress?
Yes. A queen mattress is specifically popular among couples because it provides substantial sleeping space while taking up less room than a king.
A queen mattress provides:
60 inches of total width
If two adults divide the width evenly, each person would have approximately:
60 ÷ 2 = 30 inches
of mattress width.
Actual comfort depends on sleeping habits, body size, bedroom space, and personal preference.
How Much Space Does a Queen Mattress Need in a Bedroom?
The mattress itself takes up about 33.33 square feet, but a bedroom needs considerably more space to accommodate walking areas and furniture.
For example, a queen mattress measuring approximately 5 × 6.67 feet will need additional clearance around the sides and foot of the bed.
A bedroom might also need space for:
- Nightstands
- Dresser
- Closet doors
- Bedroom doors
- Walking paths
- Chairs or benches
The ideal room size depends on the desired furniture arrangement.
Can a Queen Mattress Fit in a 10 × 10 Room?
A 10 × 10 bedroom has:
10 × 10 = 100 square feet
A queen mattress takes up approximately:
33.33 square feet
So the mattress would occupy roughly one-third of the room’s floor area.
A queen mattress can fit in a 10 × 10 room, but the remaining space can become limited once you add dressers, nightstands, doors, closets, and walking space.
Can a Queen Mattress Fit in a 12 × 12 Room?
Yes.
A 12 × 12 room has:
12 × 12 = 144 square feet
A queen mattress occupies approximately 33.33 square feet.
That leaves approximately:
144 − 33.33 = 110.67 square feet
before accounting for furniture and other fixed features.
A 12 × 12 room can therefore provide more flexibility for a queen bed and bedroom furniture.
Can a Queen Mattress Fit in a 15 × 15 Room?
Yes.
A 15 × 15 room contains:
15 × 15 = 225 square feet
A queen mattress takes up approximately 33.33 square feet.
This leaves approximately:
225 − 33.33 = 191.67 square feet
of floor area before accounting for other permanent features.
A room this size can generally provide substantial flexibility for furniture placement.
How Much Bigger Is a Queen Mattress Than a Full?
A full mattress is generally:
54 × 75 inches
A queen mattress is:
60 × 80 inches
The queen is therefore:
- 6 inches wider
- 5 inches longer
Full mattress area:
54 × 75 = 4,050 square inches
Queen mattress area:
60 × 80 = 4,800 square inches
Difference:
4,800 − 4,050 = 750 square inches
So a queen provides 750 more square inches of mattress surface than a full.
How Much Smaller Is a Queen Than a King?
A standard king mattress is:
76 × 80 inches
A queen is:
60 × 80 inches
The length is the same, but the king is 16 inches wider.
Queen area:
60 × 80 = 4,800 square inches
King area:
76 × 80 = 6,080 square inches
Difference:
6,080 − 4,800 = 1,280 square inches
Therefore, a king mattress provides 1,280 more square inches of sleeping surface than a queen.
Queen Mattress Dimensions in Centimeters
For metric measurements, a standard queen mattress is approximately:
152.4 cm × 203.2 cm
This comes from:
60 inches × 2.54 = 152.4 cm
and:
80 inches × 2.54 = 203.2 cm
Therefore:
Queen mattress = approximately 152 × 203 cm
Actual mattress dimensions can vary slightly by manufacturer.
Queen Mattress Dimensions in Meters
A standard queen mattress is approximately:
1.524 meters wide × 2.032 meters long
So its approximate dimensions are:
1.52 m × 2.03 m
Its surface area is approximately:
1.524 × 2.032 ≈ 3.10 square meters
Queen Mattress vs. Queen Bed Frame Dimensions
The mattress and bed frame are not necessarily the same size.
A standard queen mattress is approximately:
60 × 80 inches
A bed frame may be slightly larger because it needs to support the mattress and may include:
- Side rails
- Headboard
- Footboard
- Decorative trim
- Storage components
If you are measuring a bedroom, measure the entire bed frame, not just the mattress.
How Much Room Is Needed Around a Queen Bed?
The mattress itself measures approximately 5 feet by 6 feet 8 inches.
For comfortable movement, you generally want additional space around the bed.
For example, placing a queen bed against a wall can reduce the amount of clearance needed on one side, while positioning it in the center of the room requires walking space on both sides.
Consider clearance for:
- Getting into bed
- Opening drawers
- Opening doors
- Changing bedding
- Walking around the bed
There is no single required bedroom size because furniture layouts vary.
Queen Mattress Thickness
Unlike width and length, mattress thickness is not standardized.
Queen mattresses may be available in different thicknesses depending on construction and manufacturer.
Common mattress thicknesses can include approximately:
- 8 inches
- 10 inches
- 12 inches
- 14 inches
- 16 inches
A thicker mattress does not change its standard floor dimensions of approximately 60 × 80 inches.
Queen Mattress vs. Olympic Queen
An Olympic queen is wider than a standard queen.
A standard queen is:
60 × 80 inches
An Olympic queen is commonly:
66 × 80 inches
However, Olympic queen mattresses and bedding can be less common than standard queen sizes.
If you’re replacing a mattress, always verify the exact dimensions required by your bed frame.
Common Mistakes When Measuring a Queen Mattress
Mistake 1: Confusing Inches With Feet
A queen is 60 inches wide, which equals 5 feet, not 6 feet.
Mistake 2: Forgetting That 80 Inches Is 6 Feet 8 Inches
80 inches divided by 12 equals 6.67 feet.
In feet and inches, that is:
6 feet 8 inches
Mistake 3: Measuring Only the Mattress When Planning Furniture
The mattress is smaller than many complete bed frames.
Mistake 4: Assuming Every Mattress Is Exactly the Same
Manufacturers can have slight dimensional variations.
Mistake 5: Ignoring Mattress Thickness
When planning headboards, sheets, or bed frames, thickness can matter even though it does not change the floor footprint.
