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.
