King Size Bed Dimensions | Sleep Foundation
July 16, 2025 - King and California king size beds are large mattresses that cater to different needs. The California king is narrower and longer than the standard king, so it’s best for tall sleepers and those who prefer a mattress with extended length.

January 27, 2023 - A standard king-size bed, also known as an Eastern king bed, measures 76" wide by 80" long. A king-size bed is the largest standard bed size, measuring one full size larger than a queen-size bed.
Is There a Bed Bigger Than a King?
Yes, there are several bed sizes that are bigger than a standard king mattress:
- Texas King (80" x 98") — wider +4", longer +18"
- Wyoming King (84" x 84") — wider +8", longer +4"
- Vermont/Alberta King (96" x 96") — wider +20", longer +16"
- Alaskan King (108" x 108") — wider +32", longer +28"
- Family Bed (120" x 80") — wider +44", same length
- Family XL (144" x 84") — wider +68", longer +4"
Keep in mind a California King is 72" x 84". It’s 4" longer but 4" narrower than a standard King (76" x 80"), and its total area is actually a bit smaller (6,048 in² vs 6,080 in² for a standard king). So it’s not bigger overall—just longer. Great for tall sleepers or narrower rooms; couples who want maximum shoulder room usually prefer a standard King.
