Quick answer: A California King bed is 72 inches wide by 84 inches long (about 183 × 213 cm). That makes it 4 inches longer but 4 inches narrower than a standard King (76" × 80"). It suits tall sleepers up to about 6'2" and rooms that are long rather than wide. A California King bed frame must be built for 72" × 84" specifically, because a standard King frame will not fit it.
Key takeaways
- California King: 72" × 84". Standard King: 76" × 80". Both have about the same sleeping area (42 sq ft).
- The California King trades 4" of width for 4" of length, so it is the better choice for tall sleepers.
- King and California King frames, sheets and mattresses are not interchangeable.
- Recommended room size: at least 10 × 12 ft, and 12 × 12 ft or larger with nightstands.
- Candace & Basil builds California King bed frames in solid maple, in any of our designs.
California King bed frame dimensions
The mattress is 72" × 84". The frame's outside footprint depends on the design. A slim platform bed adds only a few inches. A bed with a wide, padded headboard or wraparound upholstered rails can add 6" to 10" to the width and length. Always check the overall dimensions of a frame, not just the mattress size, before you measure your room.
| Bed size | Width × length | Best for |
|---|---|---|
| Queen | 60" × 80" | Couples in smaller rooms |
| King | 76" × 80" | Couples who want width |
| California King | 72" × 84" | Tall sleepers, long and narrow rooms |
| Split California King | 2 × 36" × 84" | Adjustable bases, different firmness on each side |
| Wyoming King | 84" × 84" | California King length with 12" more width |
| Texas King | 80" × 98" | Sleepers 6'4" and taller |
California King vs. King: which is bigger?
Neither is clearly bigger. They have almost the same surface area (6,048 sq in for a California King and 6,080 sq in for a King). The California King is longer, by 4", and the King is wider, by 4". Choose a California King if you or your partner are over about 6 feet tall, or if your room is longer than it is wide. Choose a King if you want more shoulder room. If you want both, look at a Wyoming King (84" × 84").
Will a King frame fit a California King mattress?
No. A California King mattress is 4" too long for a King frame and would hang over the foot. It would also leave a 4" gap at the sides. You need a frame made for 72" × 84". The same is true for fitted sheets. California King sheets are widely available, but King fitted sheets will not fit.
What size room do you need for a California King?
- Minimum: 10 × 12 ft, with the bed's 7-foot length running along the 12-foot side.
- Comfortable: 12 × 12 ft or larger, if you want nightstands and 24" to 30" of walkway.
- Measure from the wall, and include the headboard's depth.
What to look for in a California King bed frame
- Solid hardwood construction, not particleboard or MDF, so the frame stays quiet and does not sag over time.
- A center support rail with legs. It is essential at 72" wide, especially with a heavy hybrid mattress.
- A slatted platform, so you do not need a box spring.
- Adjustable-base compatibility, if you use one. For split adjustable bases, see our Split California King guide.
- Headboard height and style that suit the room. Tall upholstered headboards suit high ceilings.
- Storage options, such as a lift-up storage base, if closet space is tight.
Upholstered vs. wood California King bed frames
An upholstered California King frame has a padded headboard that is comfortable to lean against. It softens the look of a long bed and comes in any fabric, from performance linen to velvet. An exposed wood frame has a more minimal look. Every Candace & Basil bed is upholstered over a solid maple frame, so you get a strong wood frame underneath with a soft, tailored finish on the outside.
