Quick answer: An oversized king bed is any bed bigger than a standard King (76" × 80"). The main options are the Alaskan King (108" × 108"), the largest; the Florida King (108" × 80"), the widest at standard length; the Texas King (80" × 98"), the longest for its width; and the Wyoming King (84" × 84"), a square step up from a King. Choose by whether you need width, length or both.
Key takeaways
- Need width for kids or pets? Look at the Florida or Alaskan King.
- Need length for very tall sleepers? Look at the Texas King.
- Want a bit more of both without a huge footprint? The Wyoming King is the gentlest step up.
- Every oversized king needs a custom frame and usually made-to-order bedding.

Which oversized king bed is the biggest?
The Alaskan King is the biggest. At 9 feet square it has nearly double the sleep surface of a standard King. Read the full Alaskan King bed guide or shop Alaskan King beds.
Alaskan King vs Texas King: which should I choose?
Choose the Alaskan King if several people share the bed and you need width and length. Choose the Texas King if one or two very tall people share it. At 98" long, it fits sleepers well over 7 feet, in a frame only 4" wider than a King. See our Texas King size guide and Texas King beds.
Wyoming King vs California King: what's the difference?
Both are 84" long, but the Wyoming King is 12" wider (84" vs 72"). The California King suits tall sleepers in narrower rooms. The Wyoming King adds room for a partner or pet. Compare our Wyoming King guide with the California King guide.
Is a Florida King the same as two beds pushed together?
Functionally, close: 108" is about a King plus a Twin side by side. The advantage of a true Florida King frame is one continuous headboard and base, so nothing slides apart. Families often fill it with two mattresses, such as a King and a Twin. Shop Florida King beds.
What size room do I need for an oversized king?
Add about 24" to 36" of walkway to each open side and the foot of the bed. As a rule of thumb:
| Bed | Minimum comfortable room |
|---|---|
| Wyoming King | about 11' × 12' |
| Texas King | about 11' × 12' |
| Florida King | about 13' × 11' |
| Alaskan King | about 13' × 14' |
Also measure doorways, stair turns and elevators. Very large frames can be built to assemble in sections.
Do oversized kings need special mattresses and bedding?
Yes. Most oversized kings use a single custom mattress or two standard mattresses side by side, and fitted sheets are usually made to order. Plan your mattress first, then build the frame around its actual measurement.
