King Mattress FAQs
What are king mattress dimensions?
A standard king measures 76 inches wide by 80 inches long — the same length as a queen, but 16 inches wider. Full comparison in our mattress dimensions guide.
King vs. California king — what's the difference?
A California king trades width for length: 72" x 84", four inches narrower but four inches longer. Choose Cal king for very tall sleepers or long, narrow rooms; standard king for maximum width.
Should we consider a split king instead?
If you and your partner want different firmness levels — or plan to use an adjustable base — a split king gives you the same total size with independent control of each side.
What room size fits a king bed?
Plan on a bedroom at least 12' x 10' so the bed doesn't crowd the room.
