#1 - Alaskan King
Things might be big in Texas, but they are even bigger in Alaska.
You asked what the biggest mattress size is, and THIS IS IT!
How Big Is an Alaskan King?
108″ x 108″ (274.32cm x 274.32cm)
This model clocks in at a whopping 108” x 108”. That’s a magnificent 9 feet by 9 feet of pure comfort. For perspective, the Alaskan King is almost twice the sleeping space of a queen bed.
In fact, the Alaskan King bed is the largest mattress available on the market.
(However, if you ask us really, really nicely, we could probably fabricate something custom that’s even bigger. After all, we love a good challenge!)
Why Is an Alaskan King Bed So Big?
People seek out the largest mattress size on the market for various reasons.
For some, the visual impressiveness and aesthetics of these marvelous beds seal the deal. For others, it’s the usability with a large family or for a couple who enjoy sprawling out.
In other cases, people who toss and turn or who sleep with pets may prefer the extra space this mattress affords.
Lastly, those with large luxurious homes often have large master bedrooms that make even a standard King-Sized bed look small in comparison. In such spaces, an Alaskan King can appear more proportional to the living space.
#2 - Alberta King
When a regular King bed just won’t cut it, an Alberta might be the missing puzzle piece needed for you to get the best sleep of your life.
How Big Is an Alberta King?
96″ x 96″ (243.84cm x 243.84cm)
The mighty Alberta — measuring in at a boisterous 96” x 96” — is a massive bed perfect for sprawling out and rolling around.
From big and tall folk, to co-sleeping families and even polyamorous throuples — if extra space is what you’re after, then the Alberta is a popular choice and certainly worth consideration.
#3 - Texas King
It might be cliché, but everything is bigger in Texas… even the mattresses!
The good news? You don’t need to go to Texas to sleep like a king on a cloud!
How Big Is a Texas King?
80″ x 98″ (203.20cm x 248.92cm)
The Texas King bed measures the same length as a traditional King-size mattress, but that’s where the similarities end.
Compared to a standard King, the Texas is nearly two feet wider.
However, as a fairly uncommon size, not many manufacturers carry this model. Similarly, you might find it harder to locate bedding that properly fits.
What’s Bigger — a Texas King or a California King?
“Texas is not only bigger. It’s arguably better,” we say, tipping our imaginary cowboy hat.
A Cal King measures 72″ x 84″. For comparison, the Texas King measures 14” longer and 8” wider than a traditionally designed California King. It’s no secret tall sleepers love the extra length on the Texas King Mattress.
The Texas King Bed is also a bit narrower than the Alberta, but it’s not to be outdone on length — out-measuring the Alberta by 2” in that department.
Overall, the Texas King Bed is a fantastic choice for ample room to stretch out!
#4 - Wyoming King
It seems odd to say, given its overly large size, but the Wyoming King bed is the ‘smallest’ of the oversized mattresses on the market.
Clocking in at a not-very-humble 84” x 84”, this larger mattress might be the runt of the big-bed litter, but it still has ample space to spread out on.
How Big Is a Wyoming King?
84″ x 84″ (213.36cm x 213.36cm)
Compared to a California King, the Wyoming is just as long — but a generous whole foot wider.
When compared to a traditional King-size mattress, it measures 4” longer and 8” wider, making it a great option for couples who want a little more personal space as they sleep.
#5 California King
A split California king mattress offers a unique solution for couples with differing sleep preferences and wanting more space on their bed.
How Big is the California King?
72″ x 84″ (183cm x 213.5cm)
This king mattress size variation is ideal for taller sleepers who need that extra length for comfort. The split design caters to individual preferences and provides an innovative way to enhance overall sleep quality in a shared bed setting. Whether it’s providing relief from pressure points or accommodating different sleeping habits, a split California king mattress is an excellent choice for couples looking to upgrade their sleeping experience.
BONUS: The ‘Family Bed’
“BEEP BEEP!” Back it up with this oversized mattress!
As the name implies, the Family Bed is designed for co-sleeping with a big family!
It’s perfect for those with lots of kids and not enough bedrooms, or for vacation properties where you need to sleep a lot of people in limited space.
Just How Big Is the Family Bed?
Actually, Family Beds are available in three sizes:
- EXTRA LARGE: 144″ x 84″ (365.76cm x 213.36cm)
- LARGE: 120″ x 80″ (304.80cm x 203.20cm)
- MEDIUM: 108″ x 80″ (274.32cm x 203.20cm)
As you may have assumed from those measurements, Family Beds aren’t so much tall or long as they are wide.

FAQs
Where Can You Buy Oversized Mattresses?
Good question! You’ve probably noticed that most stores don’t carry anything other than ‘standard’ mattress sizes.
And, although some boutique shops might offer a few models, they also tend to charge an arm and a leg.
MattressInsider specializes in custom mattresses and mattress sizes to accommodate virtually any space or need. We carry every size mentioned in this guide, engineered to the highest standards and guaranteed to help you get a better night’s sleep!
Where Can You Find a Bed Frame or Bedding for Oversized Mattresses?
You’ve got the mattress, but now what? Fact is, these mattresses will be incompatible with traditional foundations and bedding made for smaller sizes.
Often, the company that makes the mattress will also offer frames, foundations, and accessories that are compatible.
If that’s not the case, you may need to seek out custom fitted sheets that are tailor-made for your new bed.
You may also be able to move two smaller bed frames together to fit underneath your oversized mattress. Some oversized beds don’t even need a frame, and have been designed to lay directly on the floor!
