What is a California king bed?

A California king bed takes a mattress measuring 72 by 84 inches. It is the longest standard size sold in the United States, four inches longer than a standard king and four inches narrower. That trade is the whole point of the size: it suits sleepers over about six feet tall, who run out of mattress before they run out of width.

California king against standard king

A standard king is 76 by 80 inches, so it is wider but shorter. Choose California king for height, standard king for shared width. If two people sleep across the bed and neither is especially tall, a standard king gives each person two more inches of shoulder room. If either sleeper is tall, the four extra inches of length matter more than the width does.

How much floor space does one need?

Allow for the frame, not the mattress. These frames run 83 to 92 inches long and 72 to 78 inches wide, so the largest needs a footprint close to eight feet by six and a half. Leave at least two feet of walking room on both sides and at the foot, which puts the practical minimum room size at roughly twelve by twelve feet for comfortable access.

Do king sheets fit a California king?

No. King fitted sheets are cut for a 76 by 80 inch mattress and a California king is 72 by 84, so a king sheet is too wide and four inches too short. It will not stay on the corners. Buy sheets labelled California king or Cal king specifically. Flat sheets and duvet covers are more forgiving, but fitted sheets are not.

What are these frames made from?

This collection covers solid wood, metal, rattan and upholstered frames in velvet and boucle. Solid wood and metal frames carry weight best at this size, which matters more on a California king than a smaller bed because the span between the side rails is longer. Look for a centre support rail with its own legs on any frame this wide. Construction: engineered wood and MDF on some models, solid wood on others.

Do you need a box spring?

Most California king frames here are platform designs with slats built in, so no box spring is needed. A slatted platform supports a foam, hybrid or latex mattress directly. Check the slat spacing: gaps wider than about three inches let a foam mattress sag between them over time. A box spring is only needed on a traditional rail frame that has no slat deck.

How do you choose one?

Work in this order: confirm the room takes the footprint, confirm you actually need the length over a standard king, then choose the headboard height for the wall behind it. Headboards here run 34 to 47 inches high, and a tall headboard behind a low window or a sloped ceiling will fight the room. Storage models are worth it only if the bed sits away from a wall on at least one side.

Frequently asked questions

What is a California king bed?
A California king bed takes a mattress measuring 72 by 84 inches. It is the longest standard mattress size sold in the United States, four inches longer than a standard king and four inches narrower. The size exists for tall sleepers, who tend to run out of length before they run out of width.
What are California king bed dimensions?
A California king mattress is 72 inches wide by 84 inches long. The frame around it is larger: the frames in this collection measure 83 to 92 inches long and 72 to 78 inches wide, depending on how thick the headboard and side rails are. Always plan the room around the frame measurement rather than the mattress.
Does a king sheet fit a California king bed?
No. A king fitted sheet is cut for a 76 by 80 inch mattress, while a California king is 72 by 84 inches. The sheet is four inches too wide and four inches too short, so it will not hold the corners. Buy sheets labelled California king or Cal king. Flat sheets and duvet covers are more forgiving.
What bed is bigger than a California king?
Nothing in the standard range. Above California king you move into specialty sizes such as the Alaskan king, Texas king and Wyoming king, which are made to order rather than stocked, and need custom bedding. Among standard mattresses a California king is the longest and a standard king is the widest.
Do you need a box spring with a bed frame?
Not with most frames in this collection, which are platform designs with a slat deck built in. Slats support a foam, hybrid or latex mattress directly. Check the slat spacing, because gaps wider than roughly three inches let a foam mattress sag between them. A box spring is only required on a traditional rail frame with no slat deck.
How do you attach a headboard to a bed frame?
Most headboards bolt to two pre drilled brackets at the head of the frame. Line the headboard legs up behind the brackets, start every bolt by hand before tightening any of them, then tighten in a cross pattern so the headboard sits square. Frames sold as a complete bed have the headboard integrated and need no separate fixing.
