Twin Bed Dimensions: Will It Fit Your Room?
The real twin bed size, the space it needs around it and a quick way to try it in your room.
A twin mattress is 38 × 75 in (97 × 191 cm). Add 24 in (60 cm) on each side you get in from and the room needs to be about 86 in (218 cm) wide. With one side against a wall it needs about 62 in (157 cm).
Twin Bed Size
- Mattress: 38 × 75 in (97 × 191 cm). This is the standard US size, the same at every shop.
- The frame is bigger than the mattress. A frame often adds a few inches to each side and the foot, and a headboard or footboard adds more to the length. Check the listing for the frame's own size.
- A Twin XL is the same 38 in (97 cm) wide but 80 in (203 cm) long. It is common in dorm rooms and for adjustable bases.
Space You Need Around a Twin Bed
Nooked checks the same gaps this table uses: 24 in (60 cm) is comfortable on each side you get in from, and 18 in (45 cm) is the least that works. Widths below use the mattress size, so add the frame's extra when you know it.
- Both sides open, comfortable: 86 in (218 cm) wide. 24 in (60 cm) each side.
- Both sides open, tight: 74 in (188 cm) wide. 18 in (45 cm) each side.
- One side against a wall: 62 in (157 cm) wide. Only one person gets in without climbing over the other.
- Length with a walkway at the foot: 99 in (251 cm). 24 in (60 cm) at the foot lets people walk past. A wardrobe in front of the bed needs 24 to 36 in (60 to 90 cm) for its doors.
Where a Twin Bed Fits
A twin suits a child's room, a guest room or a small bedroom. A twin is the size to pick when floor space is the problem. It fits in a room under 8 ft (2.4 m) wide, and two of them fit side by side in a guest room. It is a tight fit for an adult over about 6 ft (1.8 m), who will want the Twin XL.
The next size up, the Full, is 16 in (41 cm) wider. If you are between two sizes, measure the room first and test both.
