California King Bed Dimensions: Will It Fit Your Room?
The real California king bed size, the space it needs around it and a quick way to try it in your room.
A California king mattress is 72 × 84 in (183 × 213 cm). Add 24 in (60 cm) on each side you get in from and the room needs to be about 120 in (305 cm) wide. With one side against a wall it needs about 96 in (244 cm).
California King Bed Size
- Mattress: 72 × 84 in (183 × 213 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 California King is sometimes called a Western King. It is 4 in narrower than a standard King but 4 in longer, so it can fit a room that is narrow but long.
Space You Need Around a California King 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: 120 in (305 cm) wide. 24 in (60 cm) each side.
- Both sides open, tight: 108 in (274 cm) wide. 18 in (45 cm) each side.
- One side against a wall: 96 in (244 cm) wide. Only one person gets in without climbing over the other.
- Length with a walkway at the foot: 108 in (274 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 California King Bed Fits
A California king suits a tall sleeper in a long, narrower main bedroom. A California King is the choice for a tall sleeper, or a room that is longer than it is wide. Its extra 4 in (10 cm) of length means more room at the foot than a King, so check the walkway there.
The King is 4 in (10 cm) wider and 4 in (10 cm) shorter. If you are between two sizes, measure the room first and test both.
