If you’re shopping for a new bed, you might be wondering which mattress size is the largest. The simple answer is the Alaskan King, but the full story involves more than just one name.
There’s a whole world of oversized and specialty mattresses beyond the standard ones you know. Choosing the right one depends on your room, your needs, and who’s sleeping in it. Let’s break down all the options so you can make the best choice for your space.
Which Mattress Size Is The Largest
The undisputed champion for the largest standard mattress size is the Alaskan King. It measures a massive 108 inches wide by 108 inches long, creating a perfect 9-foot by 9-foot square. This size provides an incredible amount of space for families, couples with pets, or anyone who simply loves sprawling out.
Standard Mattress Sizes: From Smallest to Largest
Before we get into the true giants, it’s helpful to review the common mattress sizes. These are the ones you’ll find in most furniture stores.
- Twin: 38″ x 75″ – Ideal for a single sleeper, often used in children’s rooms or bunk beds.
- Twin XL: 38″ x 80″ – Offers extra legroom, popular for college dorms and taller individuals.
- Full (Double): 54″ x 75″ – Fits two people somewhat cozyly, but better for a single adult who wants more space.
- Queen: 60″ x 80″ – The most popular size. It offers good space for two people and fits in most bedrooms.
- King: 76″ x 80″ – The standard “large” size. It gives each person in a couple as much width as a twin bed.
- California King: 72″ x 84″ – Narrower but longer than a standard King. Best for very tall individuals over 6’4″.
The “Bigger Than King” Category: Specialty Sizes
This is where we find the largest mattresses. They are not as commonly stocked and are often considered custom or specialty items.
Wyoming King
A step up from a standard King, the Wyoming King measures about 84 inches wide by 84 inches long. It’s a large square that provides significant extra width and length compared to a California or standard King. It’s a great compromise before jumping to the very largest options.
Texas King
The Texas King is designed for length and width. It typically measures 80 inches wide by 98 inches long. This makes it ideal for tall basketball players or families who like to pile into bed together for movies. It’s longer than an Alaskan King but not as wide.
Alaskan King
As mentioned, the Alaskan King is the largest standard mattress size available. At 9 feet by 9 feet, it’s essentially four Twin XL mattresses put together. You need a very large bedroom to accommodate it, along with specialized bedding that can be harder to find and more expensive.
How to Choose the Right Large Mattress for You
Biggest doesn’t always mean best for your situation. Here are the key factors to consider before investing in a giant bed.
Measure Your Bedroom
This is the most critical step. A good rule of thumb is to have at least 2 to 3 feet of walking space on each side of the bed and at the foot. For an Alaskan King, your room should ideally be at least 14 feet by 14 feet to feel comfortable. Don’t forget to account for other furniture like dressers and nightstands.
Consider Who Will Use It
- Couples: A standard King or California King is usually perfect. If you both move a lot or sleep with pets/kids, a Wyoming King offers more luxury.
- Families: For frequent family cuddles or movie nights, the square footage of a Wyoming or Alaskan King can be a wonderful investment.
- Tall Individuals: Prioritize length. A California King or Texas King is better than a wider, shorter Alaskan King.
Think About Practicalities
Oversized mattresses come with logistical challenges. Make sure you can get it up your staircase and through doorways. Also, check the availability and cost of sheets, mattress protectors, and bed frames. These items are often custom-order and carry a higher price tag.
The Pros and Cons of an Extra Large Mattress
Advantages
- Ample Space: No more fighting for blankets or bumping into each other. Everyone has plenty of room.
- Great for Families: Perfect for weekend morning cuddles with kids or pets.
- Ideal for Combination Sleepers: If you toss and turn, you have the whole surface area to do so without disturbing your partner.
Disadvantages
- High Cost: The mattress, frame, and bedding are all significantly more expensive.
- Bedding Challenges: Finding fitted sheets, duvet covers, and mattress pads can be difficult and requires specialty retailers.
- Space Hog: It dominates the bedroom, leaving little room for anything else.
- Difficult to Move: Getting it into your home and maneuvering it during a move is a major undertaking.
Steps to Buying a Specialty or Oversized Mattress
- Confirm Your Room Dimensions: Measure twice, and tape out the dimensions on your floor to visualize the space.
- Research Retailers: Not all companies make these sizes. Look for brands that specialize in custom or oversized mattresses.
- Check Return Policies: Due to their custom nature, return policies are often strict or non-existent. Some may offer exchanges only.
- Order Bedding First: It sounds backwards, but secure your sheets before the mattress arrives. You don’t want a 9-foot bed with nothing to cover it.
- Plan the Delivery: Ensure you have a clear path and, if necessary, hire professional movers to handle the installation.
FAQ Section
What is bigger than a king size bed?
Several sizes are bigger than a standard King. The California King is longer. The Wyoming King (84″x84″) and Texas King (80″x98″) are both larger in total area. The absolute largest is the Alaskan King (108″x108″).
Is a California King bigger than a King?
It depends on what you mean by “bigger.” A standard King (76″x80″) has more width, making it better for couples who want personal space. A California King (72″x84″) is narrower but longer, making it the better choice for very tall single sleepers or couples.
What is the biggest mattress you can buy?
The Alaskan King is the biggest standard specialty mattress size at 9 feet by 9 feet. However, you can technically order custom mattresses in even larger dimensions if you have the space and budget, though these are extremely rare.
Can you get sheets for an Alaskan King mattress?
Yes, but you typically cannot find them in regular stores. You need to purchase them from the mattress manufacturer or from online specialty retailers that cater to oversized bedding. It’s a good idea to order them well in advance of your mattress delivery.
Caring for Your Large Mattress
Protecting your investment is key. Always use a high-quality, waterproof mattress protector designed for its dimensions. Rotate the mattress head-to-foot every 3-6 months to ensure even wear, especially since these mattresses are so heavy and hard to move. Vacuum the surface reguarly to keep dust and allergens at bay.
Choosing the largest mattress size is a big decision that goes beyond just the label. While the Alaskan King holds the title, the right “largest” mattress for you is the one that fits your life, your room, and your sleep needs perfectly. Take your time, do the math, and you’ll find a bed that offers years of comfortable and spacious sleep. Remember to account for all the extra costs and logistics, from bedding to delivery, to avoid any suprises.
