Quick Answer: An Alaskan King bed measures 108" x 108" (9 feet by 9 feet), providing 81 square feet of sleeping surface, nearly double a standard King. You'll need a bedroom of at least 14' x 14' to accommodate it comfortably. Prices start around $3,000-5,000 for the mattress alone.
Updated May 2026. The Alaskan King has become a status symbol in the sleep world. With searches up 22% this year, more people are asking the question: is all that space actually worth it?
The honest answer: for most people, no. But for the right situations, it's life-changing. Let's figure out which camp you're in.
"An Alaskan King is the largest standard oversized bed sold in North America. At 108 inches by 108 inches, it carries 81 square feet of surface, roughly 93 percent more than a standard King. The trade-off is real. Custom sourcing, custom bedding, custom delivery. After helping families in Brantford fit this size, the honest call is that fewer than one in ten buyers genuinely need it. The Alberta King at 96 by 96, or a Wyoming King at 84 by 84, solves the same family-and-pet problem for thousands less and fits actual Canadian rooms."

Research Finding: The Canadian Sleep Society identifies partner movement as one of the leading causes of nighttime waking for couples who share a bed. A wider sleep surface limits physical contact and reduces motion transfer between partners. This is particularly relevant for Alaskan King buyers where one partner is a light sleeper or moves frequently during the night.
How does an Alaskan King compare to other bed sizes?
Understanding the Alaskan bed size relative to other mattress sizes helps you decide if this oversized option is right for your space.
Let's put the Alaskan King in perspective with other bed sizes:
| Size | Dimensions | Square Feet | Room Needed | Price Range |
|---|---|---|---|---|
| Queen | 60" x 80" | 33 sq ft | 10' x 10' | $400-1,500 |
| King | 76" x 80" | 42 sq ft | 12' x 12' | $600-2,000 |
| California King | 72" x 84" | 42 sq ft | 12' x 12' | $600-2,000 |
| Texas King | 80" x 98" | 54 sq ft | 13' x 13' | $2,000-4,000 |
| Wyoming King | 84" x 84" | 49 sq ft | 13' x 13' | $2,500-4,500 |
| Alaskan King | 108" x 108" | 81 sq ft | 14' x 14'+ | $3,000-6,000+ |
| Alberta King | 96" x 96" | 64 sq ft | 13' x 14' | $2,800-5,000 |

The Alaskan King provides 93% more sleeping surface than a standard King. That's roughly the equivalent of adding two Twin beds worth of space.
Should Canadians buy an Alberta King or an Alaskan King?
Canada's Oversized Secret: While Americans debate Alaskan versus Wyoming Kings, Canadians have their own contender: the Alberta King at 96" x 96". It was designed as a more practical alternative to the full 108" Alaskan, and for most Canadian homes, it's actually the smarter choice.
| Feature | Alberta King (96" x 96") | Alaskan King (108" x 108") |
|---|---|---|
| Sleeping surface | 64 sq ft | 81 sq ft |
| Extra space vs. standard King | 52% more | 93% more |
| Minimum bedroom | 13' x 14' (fits more Canadian homes) | 14' x 14'+ (fits fewer homes) |
| Typical mattress cost | $2,800-5,000 | $3,000-6,000+ |
| Bedding availability | Custom online, slightly more options | Custom only, fewer suppliers |
| Delivery difficulty | Very difficult | Extremely difficult |
| Comfort for | 2 adults + 1-2 kids or large pets | 2 adults + 2-3 kids or multiple pets |
| Canadian sourcing | Some retailers can source | Almost always custom order only |

Choose an Alberta King When:
- Your bedroom is 13' x 14' to 14' x 14': The Alberta King fits; the Alaskan often won't
- Budget matters: Save $500-1,500 on the mattress, plus less on custom bedding
- Family of four: Two adults and two young children sleep comfortably, you'd need the Alaskan when the kids are teenagers and everyone's bigger
- You value slightly easier logistics: Still custom, but marginally more suppliers carry Alberta King dimensions
The Alaskan King Is Worth It When:
- You have a confirmed 14' x 14'+ bedroom with 3 feet of clearance on all sides
- You're co-sleeping with multiple children or several large dogs and those extra 12" per side genuinely matter
- You're building or renovating and can design the room around the bed (it happens)
Who Actually Needs an Alaskan King?
You Might Need One If:
The Wyoming King bed is the most popular oversized bed alternative in Canada. At 84" x 84", a Wyoming King bed offers significantly more room than a standard King while still fitting in most master bedrooms. For Canadians who want extra sleeping space without the commitment of a full Alaskan King, the Wyoming King bed is often the practical sweet spot.
- Co-sleeping families: Parents who want kids nearby without everyone's elbows in everyone's faces
- Large breed dog owners: Great Danes, Mastiffs, and other bed-hogs finally have room
- Couples who need maximum separation: When a Split King still isn't enough space
- Very tall or large individuals: Standard Kings can feel cramped
- Multi-pet households: When the "no pets in bed" rule has completely failed
You Probably Don't Need One If:
- Your bedroom can't comfortably fit it (most can't)
- You're a couple without kids or pets in bed
- Budget is a primary concern (everything costs more: mattress, sheets, frames)
- You move frequently (good luck getting it through doorways)
"When a couple comes in asking about an Alaskan King, I always ask who else is in the bed. If it is two adults and a single small dog, a Wyoming King or even a standard King with an adjustable base does the job and they sleep just as well. Where the Alaskan King actually earns its keep is the family co-sleeping with two or three kids, or someone with a Great Dane and a partner who is a heavy mover. Surface area only matters if every square foot is being used."

Does an Alaskan King fit in a typical Brantford home?
Let's be honest about local housing: most Brantford master bedrooms won't fit an Alaskan King comfortably.
Typical Brantford Bedroom Sizes:
- Older homes (pre-1980): 11' x 12' average, sometimes smaller
- 1980s-2000s builds: 12' x 13' typical
- Newer developments: 13' x 14' becoming more common
- Custom/luxury homes: 14' x 16'+ possible
For an Alaskan King (9' x 9'), you need at least 2-3 feet of clearance on three sides for walking and furniture. That means a minimum room size of 14' x 14', ideally larger.
More Realistic Options for Most Brantford Homes:
- Wyoming King (7' x 7'): Fits rooms 13' x 13' and up
- Texas King (80" x 98"): Extra length, moderate width increase
- Standard King with adjustable base: Maximizes existing footprint
How much does an Alaskan King really cost?
The sticker price is just the beginning. Here's what to budget:
| Item | Standard King Cost | Alaskan King Cost |
|---|---|---|
| Mattress | $800-2,000 | $3,000-6,000 |
| Bed Frame | $200-800 | $800-2,500 (custom) |
| Sheet Set | $50-150 | $150-400 |
| Duvet/Comforter | $100-300 | $300-800 |
| Mattress Protector | $50-100 | $150-300 |
| Total Setup | $1,200-3,350 | $4,400-10,000+ |

Ongoing costs are higher too: sheets need replacing, dry cleaning an Alaskan King comforter is more expensive, and replacing the mattress in 8-10 years means another major investment.
What are the delivery and bedding challenges for an Alaskan King?
Delivery and Installation:
- Won't fit through standard doorways in one piece
- Usually requires removal of door frames or window delivery
- Stairs can be impossible; crane delivery for second floors isn't unheard of
- Many delivery services won't handle oversized mattresses
Moving Day:
- Plan to leave it behind or sell with the house
- Moving companies charge premium rates for oversized items
- May not fit in your next home
Sheet Availability:
- Not available in most stores
- Online ordering only for most brands
- Expect 2-3 week shipping times
- Returns are complicated
What if you're set on an oversized bed?
For most families, here are better-value alternatives that solve the same problems:
Option 1: Wyoming King (84" x 84")
- 49 square feet (vs 42 for standard King)
- Fits most larger bedrooms
- Easier to find bedding
- $2,500-4,500 for mattress
Option 2: Two Queens Pushed Together
- Combined: 120" x 80" (wider than Alaskan King, but shorter)
- Uses standard, affordable bedding
- Each person controls their own mattress firmness
- Total cost: $1,500-3,000 for two quality Queens
Option 3: King + Quality Mattress + Adjustable Base
- Invest in the best King mattress rather than a mediocre oversized one
- Add adjustable bases for versatility
- Better sleep per square foot

How do you buy an Alaskan King mattress in Canada?
Most Canadian mattress retailers do not stock Alaskan Kings. This isn't a supply problem, it's a demand problem. We've helped people source them over the years, and there are a few things you should know before committing.
Canadian Retailers and Sourcing Options
Your main paths for buying an Alaskan King mattress in Canada:
- Custom order through a local retailer (like us): We can source custom-sized mattresses and coordinate delivery. Lead times are typically 8-12 weeks. This is usually the best option for Canadians because you get local service and support if anything goes wrong.
- Order from a Canadian online mattress company: A few Canadian manufacturers will produce custom sizes on request. Expect 10-14 week lead times and higher shipping costs for oversized freight.
- Import from a US supplier: Some specialty US companies make Alaskan Kings. Be aware that you'll pay import duties (typically 9.5-18% on mattresses depending on materials), plus international freight for an oversized item can add $400-900 to the cost. Warranty claims on US-purchased mattresses can also be complicated across the border.
The Canadian Shipping Reality
An Alaskan King at 108" x 108" is not a standard freight item. Here's what shipping actually looks like:
- Standard furniture delivery trucks can usually accommodate them lying flat, but only if rolled or in two pieces
- Memory foam Alaskan Kings can be compressed and rolled for shipping; innerspring or hybrid versions generally cannot
- White-glove delivery (where the crew brings it to your room and sets it up) adds $200-500 but is usually worth it for this size
- Budget an additional $150-400 for delivery within Ontario; western provinces often add another $100-200
Doorway and Staircase Math
This is where most buyers get an unwelcome surprise. Let's look at actual numbers:
- Standard Canadian interior doorway: 32-36 inches wide, 80 inches tall
- Alaskan King compressed for delivery: Still typically 40-50" wide when rolled
- Unrolled in the room: 108" wide, you need a room large enough to unfurl it before placing
- Standard exterior door: 36 inches, still too narrow for an unrolled Alaskan King
Most deliveries require removing the bedroom door from its hinges, and in some cases removing the door frame trim. For second-floor bedrooms with tight staircases, this becomes a significant challenge. We've seen buyers have to use window delivery (crane or careful maneuvering through a window opening) for second-floor master bedrooms.
Before ordering, measure your hallway width, staircase width (if applicable), bedroom door width, and the path from your front door to your bedroom.
Bedding: Where Canadians Actually Buy It
Standard retail stores, Winners, HomeSense, IKEA, Hudson's Bay, do not carry Alaskan King sheets or duvets. Your options:
- US online specialty retailers: A few US companies make them. Shipping to Canada adds $40-80 per set; returns are complicated
- Etsy custom sewn: Some Canadian and US sewers make custom bedding. Quality varies; budget $250-500 for a sheet set
- Custom from fabric: A local seamstress can make custom sheets and duvet covers from materials you choose. Often the best quality option, but the most effort
Budget $400-700/year for bedding replacement on an Alaskan King, versus $100-200/year for a standard King.

What are the exact dimensions of an Alaskan King?
9 feet by 9 feet (108" x 108"). That's bigger than two California Kings side by side. It's massive, only makes sense if you have a very large bedroom.
Where can I buy an Alaskan King mattress in Canada?
They're custom orders. We can help you get one, but expect 6-12 weeks for manufacturing and delivery. Most standard mattress retailers don't stock them.
Can I find sheets for an Alaskan King?
You'll need custom sheets. A few online retailers make them, or you can have them sewn. Budget $200-400 for a quality set. Blankets and duvets also need to be custom.
How much does an Alaskan King cost?
Expect $3,000-8,000+ depending on materials and construction. Plus custom bedding, custom frame (if needed), and potentially delivery challenges. It's a significant investment.
Will it fit in my bedroom?
You need at least a 14' x 14' room to have walking space around it. Measure doorways, hallways, and stairs too, you might need to bring it in pieces.
