Alaskan King vs Wyoming King vs Texas King: Which Oversized Bed Do You Have?
A standard king felt roomy — until the kids, the dog, and your own six-foot frame all showed up for the night. If you've started shopping oversized beds, the Alaskan King vs Wyoming King question comes up fast. Here's how all three giant kings actually compare.
All three beds are named after big U.S. states for a reason: they're the largest mattresses you can buy, well beyond the 76″ × 80″ standard king. But "oversized" isn't one size — the shape and footprint are wildly different, and the right one depends on your room, your height, and how many people (and pets) pile in. Let's settle it.
Oversized Bed Dimensions at a Glance
Before we get into the personalities of each bed, here are the exact oversized bed dimensions side by side. This one table answers most of what people mean when they search "alaskan king vs wyoming king."
| Bed | Dimensions | Shape | Sq ft | Best for |
|---|---|---|---|---|
| Wyoming King | 84″ × 84″ | Square | 49 | Couples + 1 kid |
| Texas King | 80″ × 98″ | Rectangle | 54 | Tall sleepers |
| Alaskan King | 108″ × 108″ | Square | 81 | Whole family |
Quick answer: the Alaskan King is the biggest bed size on the market. The Wyoming King is the most room-friendly. The Texas King is the one for very tall sleepers.
Meet the Three Oversized Kings
Wyoming King (84″ × 84″) — The Square Compromise
The Wyoming King bed size is a tidy 7-foot square — a full foot wider and longer than a standard king, but without swallowing the whole room. It's the smallest of the oversized trio, which is exactly its appeal: it fits a normal-ish master (about 12 × 12 ft) and still sleeps two adults plus a small child or a dog. If the Alaskan King feels like too much, this is your starting point. See the Wyoming King mattress.
Texas King (80″ × 98″) — Built for Tall Sleepers
The Texas King keeps a standard king's 80-inch width but stretches to a generous 98 inches long — 18 extra inches so tall sleepers over 6′5″ stop hanging off the end. It's the only rectangular option here, which makes it a smart fit for a long, narrow bedroom. Couples who sleep with a big dog at their feet love the extra length too. Browse the Texas King mattress.
Alaskan King (108″ × 108″) — The Biggest Bed You Can Buy
Then there's the giant. The Alaskan King bed dimensions are a jaw-dropping 9 × 9 feet — 81 square feet of surface, the biggest bed size you can order. This is the true family bed: two adults plus three or four kids and pets, with room to spare. It's the ultimate oversized king bed for co-sleeping households and anyone who's tired of negotiating for territory. Explore the Alaskan King mattress.
FAQs: Alaskan King vs Wyoming King (and Everything In Between)
Which is bigger, an Alaskan King or a Wyoming King?
The Alaskan King is far bigger. At 108″ × 108″ it's the largest mattress made, while the Wyoming King is 84″ × 84″. That's two full feet more in both width and length — roughly 32 more square feet of sleeping space.
What room size do I need for an oversized bed?
Plan on about 12 × 12 ft for a Wyoming or Texas King, and 16 × 16 ft for an Alaskan King, so you still have room for nightstands and a walkway. Measure your master before you buy any oversized mattress.
Do oversized beds need special sheets?
Yes. None of these sizes use off-the-shelf king bedding, so budget for custom oversized bedding — fitted sheets, duvets, and mattress protectors sized to match.
Which oversized king is best for tall sleepers?
The Texas King, hands down. Its 98-inch length is built for anyone over 6′5″. If you also want more width, the square Alaskan King works — but the Texas King fits more rooms.
How to Choose Your Oversized Bed
With the specs settled, the alaskan king vs wyoming king vs texas king decision really comes down to three honest questions:
How much floor space do you have? Your room decides more than anything. A snug master rules out the Alaskan King no matter how tempting it is — the Wyoming King is the graceful compromise. Not sure what fits? Our mattress size chart lays every dimension out.
Who's sleeping on it? A couple who wants elbow room leans Wyoming. A very tall sleeper or a couple with a big dog leans Texas. A co-sleeping family with kids and pets should go Alaskan — it's the only family bed roomy enough for everyone.
What's your all-in budget? Remember the mattress is just the start. Add an oversized bed frame and custom bedding, and the total climbs with the size. Buy the bed that fits your life, not just the biggest one on the page.
If you measured a perfect 7-foot square, you've got a Wyoming King. A long rectangle at 80″ × 98″ is a Texas King. And a room-filling 9 × 9 ft? That's the Alaskan King — the largest mattress money can buy. Whichever giant king you're leaning toward, match it to your room first, your sleepers second, and your budget third, and you'll land on the right one.
