Full size bed dimensions and mattress size
A Full mattress, also sold as a Double in the US, is 54 × 75 in on Target's chart: 137.2 × 190.5 cm, or 4 ft 6 in × 6 ft 3 in. One Sleep Foundation guide gives 54 × 74 in, so both appear below. Two people sharing a Full get 27 inches each; one sleeper gets the whole 54.
What we found
Four published lengths for one size
Most references we checked give a width of 54 in (IKEA states a 53⅛ in mattress for its Full frames); the length varies more. These are the Full lengths we found, each on its own page:
The 17 pages (read on 30 September 2026) compared on Mattress size disagreements give a Full width of 54 in on 10 pages and 53 in on 5.
- 75 in: Target's chart and Sleep Foundation's double-bed guide.
- 74 in: the chart in Sleep Foundation's twin guide.
- 74½ in: Tuft & Needle's Original Mattress II, sold as a Full (54 × 74½ in).
- 74⅜ in: the length of the 53⅛ × 74⅜ in mattress IKEA states for its MALM and TARVA Full frames.
A frame made for 53⅛ × 74⅜ in and a mattress labelled 54 × 75 in differ by ⅞ in of width and ⅝ in of length. If the fit is tight, go by the frame's stated mattress size and the mattress's product size, not the size name.

Full size bed dimensions in inches, cm and feet

| Inches, second source | 54 in | 74 in | Sleep Foundation |
| Centimetres | 137.2 cm | 190.5 cm | Our conversion |

First row: Target mattress size chart; second row: Sleep Foundation twin guide, both checked 2026-09-24. The other rows convert Target's figure; its surface is 4,050 sq in (28.1 sq ft, 2.61 m²). On Sleep Foundation's 54 × 74 in, the Full is 137.2 × 188 cm (4 ft 6 in × 6 ft 2 in).
Can two people sleep on a Full bed?
They can, with 27 inches each. That is 11 or 12 inches less than a Twin gives one person (38 or 39 in, depending on the source) and 3 inches less per person than a Queen. Length is the other limit. The National Bed Federation advises a bed 10 to 15 cm (4 to 6 in) longer than the tallest person in it, which on a 75 in Full means sleepers up to about 5 ft 9 in to 5 ft 11 in (176 to 181 cm). On the 74 in figure it drops to 5 ft 8 in to 5 ft 10 in.
A Queen (60 × 80 in) adds 6 inches of width and 5 of length, which raises that height limit to about 6 ft 2 in to 6 ft 4 in. Both beds are drawn to scale on Queen vs Full.
Will a Full bed fit a 10 × 10 ft room?
Yes. With a 30-inch walkway on both sides and at the foot, the mattress needs 9 ft 6 in × 8 ft 9 in, which leaves 6 in across a 10 ft wall and 15 in along the other. Pushed against a wall on one side, it needs 7 ft × 8 ft 9 in. A frame adds to both figures, as the second column shows.
| Layout | Mattress only (54 × 75 in) | On the IKEA MALM bed frame (59 × 78⅜ in) |
|---|---|---|
| Walkway on both sides and at the foot30 in (76 cm) on both long sides and at the foot | 9 ft 6 in × 8 ft 9 in2.90 m × 2.67 m, 7.72 m² (83.1 sq ft) | 9 ft 11 in × 9 ft ⅜ in3.02 m × 2.75 m, 8.32 m² (89.6 sq ft) |

Walkway: 30 in, from Which? (2ft 6in) and the 2010 ADA Standards (305.3 and 806.2.3). For this Full with both sides open, that is 54 + 30 + 30 = 114 in wide and 75 + 30 = 105 in long, or 9 ft 6 in × 8 ft 9 in.
Full size sheets, comforters and frames
| Item | Size | What it means for this bed |
|---|---|---|
| Fitted sheet | 54 × 75 in | Sold under the same size name as the mattress. Check the mattress's stated size and the pocket depth. See fitted sheet pocket depth. |
| Comforter | 78 to 88 × 86 to 92 in | Hangs 12 to 17 in over each side of a 54 in mattress. A side is covered only if the overhang is at least the mattress depth. |
Comforter range: Sleep Foundation comforter sizes, read on 2026-09-25; the overhang is our arithmetic. Parachute sells one Full/Queen duvet cover, which on a Full hangs about 3 inches further over each side than on a Queen.

Figures: Target mattress size chart, checked 2026-09-24. Areas, differences and per-person widths are our arithmetic on those figures.
The two share a 75 in length, so a child moving up from a Twin gains width only. On Sleep Foundation's 38-inch Twin the Full is 16 inches wider, not 15. See Twin bed dimensions for the smaller size.
A US Full and a UK Double differ slightly
Both are called "double", and a UK Double has the imperial size 4ft 6in × 6ft 3in, equivalent to 54 × 75 in. But it is sold as 135 × 190 cm, which is 2.2 cm narrower and 0.5 cm shorter than a Full. Which? lists the UK Double fitted sheet at 135 × 190 cm; see UK Double bed size.
| Market and name | Size | Compared with the Full |
|---|---|---|
| UK Double | 135 × 190 cm53.1 × 74.8 in | 2.2 cm (0.9 in) narrower, 0.5 cm (0.2 in) shorter |
| French Double 140 × 190 | 140 × 190 cm55.1 × 74.8 in | 2.8 cm (1.1 in) wider, 0.5 cm (0.2 in) shorter |

Common questions
Is 60 × 80 a Full size bed?
No. 60 × 80 in is a Queen on Target's chart; a Full is 54 × 75 in. See Queen bed dimensions.
Is a Full bed the same as a Double?
In the US, yes: Sleep Foundation writes "full/double" for 54 × 75 in. In the UK, a Double is 135 × 190 cm.
How big is a Full bed in metres?
1.372 × 1.905 m on Target's figure, or 1.372 × 1.88 m on the 74 in figure.
How thick is a Full mattress?
The size name sets only width and length. Depth is the maker's choice: Tuft & Needle's Full is 12 in deep. Check it before buying fitted sheets.
