Custom Mattress Sizes in the US

For those who like to spread out while they take a snooze or people who are over 10 feet tall, there’s some great news.

There are plenty of custom-sized beds and mattresses of gigantic proportions available! 

For when the queen size just isn’t cutting it, you can consider upgrading to the Olympic Queen-sized mattress. This will give you an extra 6 inches of width on the standard queen-size mattress. 

King mattresses also come in a range of non-standard sizes. While these bed sizes aren’t common (and many will require absolutely huge bedrooms to fit them in), they can be easily ordered from many bed manufacturers in the US. 

The next size up from the California King-size mattress is the Texan King which measures in at 8 inches wider and 14 inches longer than a California King. 

Not to be outdone, the great state of Wyoming chipped in and submitted their slumber monster-sized mattress.

The Biggest Mattress in the World

While the Alaskan King-sized mattress takes the prize for the biggest commercially available bed in the US, some very tall folk in a faraway land were not prepared to accept the “largest bed” claim lying down.

With the pursuit of no longer bumping ankles on bed boards, a small group within the world’s tallest nation, The Netherlands, took matters into their own hands.

In 2011, the 166 inhabitants of a tiny little Dutch village called Hertme decided to get cozy and make the world’s largest bed.

The colossal bed measures 26.5 m (86 ft 11 in) long, 16.44 m (53 ft 11 in) wide, and is large enough to sleep the entire village.

Things to Consider When Purchasing Custom-sized Mattresses

It’s easy to get carried away when looking for a new mattress, but before you get out the credit card and proclaim yourself as slumber king, there are a few things worth considering. 

Room Size

First and foremost, your new mattress has to fit on your bed frame, and more importantly, in your bedroom! When sizing a new mattress, you’ll want to allow plenty of room on at least 3 sides.

Allow a minimum of 3 feet to easily move around the mattress and any furniture in your bedroom. Don’t forget to consider where doors swing and allow enough room. 

Number of Sleepers

Most commonly, there’s going to be two people sharing a king-sized bed of any proportion. However, as any parent or owner of furry friends will know, the bed can get a few extra participants from time to time.

Consider your situation and how many people will normally be frequenting during the nocturnal hours, and make sure no one is left out or woken by a partner’s tossing and turning. 


There is a price to pay when supersizing your sleeping arrangements. The bigger the mattress you buy, the more expensive it is likely to be.

Don’t forget, you’ll also need to buy bedding which also increases in cost the larger you go. 


Gone are the days when you buy a new mattress from the showroom and strap it to the roof of your car and casually drive off into the sunset.

Nowadays, mattresses are delivered and it’s likely that you’ll be quizzed by the sales agent regarding access for delivery before you buy. 

Check the largest door opening size in your home and if a mattress will fit. If you’re living in an apartment block, speak to your building supervisor about the size of the service elevator.

 No one wants to carry a huge Alaskan King-sized mattress up 30 flights of stairs! 


The Californian King is a great-sized mattress for many, but it’s definitely not the biggest mattress available in the US today.

For those with gigantic bedrooms and looking for the ultimate slumber statement, the largest bed you can buy is the enormous Alaskan King mattress, which offers 81 square feet of space!
