Olympic Queen Size Mattress Dimensions

Casper King Size Mattress Unboxing
  • Dimensions: 66 x 80
  • Recommended Minimum Room Size: 10 x 10

Olympic Queen Mattresses are a bit wider than Queen mattresses, which is perfect for couples, or individuals, who like to spread out during the night. Olympic Queen mattresses also are a good middle ground between a Queen and a King in regards to width, so if your room isnt accommodating of a King, you could still get a wider mattress by buying an Olympic Queen. The one thing about Olympic Queens is that they can be hard to find because theyre not considered to be a standard size, and most mattress brands only carry standard sizes. To find an Olympic queen, you may need to shop around at mattress retailers in your area. Another thing to note is it may be harder to find accessories, such as sheets and mattress covers, for Olympic Queen mattresses.

All in all, these mattresses are ideal for taller couples or couples who would like a little more room without fully upgrading to a King size mattress.

Do Queen Mattresses Come In Different Sizes

Yes, there are numerous variations of the traditional queen bed size. If youre looking for an RV size mattress, the Queen RV is about 5 inches shorter than a regular queen bed.

An Olympic queen mattress is 6 inches wider than a standard queen, while a California king is 4 inches longer than a traditional queen. There are also split queen mattresses with the same dimensions as a regular queen bed, but the bed is divided into halves to promote greater customization on an adjustable bed.

Choosing The Best Mattress Size

So how does one choose the best mattress size? It mostly comes down to four factors:

  • How many people will sleep on the mattress

  • Your budget

A good mattress size gives you space to move and stretch out, ensuring your arms or legs arent hanging over the mattresss sides.

While theres no set answer to this, the mattress size most couples opt for usually boils down to the size of their room. If you have a spacious master bedroom, then a king or California king-sized bed is going to provide you ample space, and a comfortable nights sleep.

Olympic Queen Mattress Size

Get Wyoming King, Texas King &  Alaskan King Beds Here

Olympic queen-sized mattresses have dimensions of 80-inches in length and 66-inches in width. They provide an additional 6-inches of width when compared to a standard Queen mattress.

The extra width is suitable for times when couples need some personal space when they are in bed and six additional inches helps with that. Olympic queen size also accommodates your child who needs some cuddling too if they wake up during the night, which is an added advantage of this size.

Olympic Queens are not a common size which means you wont have as large of a selection of sheets to choose from when you purchase sheets.

You can use flat sheets for a king and tuck them under the mattress if you cant find fitted sheets that match your décor.

Overall Height Of The Mattress

The top of your mattress will be a combination of the height of the bed or platform plus the height of the mattress. If you will use a box spring, you have to also add the height of the box spring. Some beds are so tall you need steps to get into them. While this may look romantic, if youre planning to have a baby, consider the difficulty of safely navigating the steps holding an infant who wants to nurse in the middle of the night when youre exhausted.

Too much height can also be difficult for someone who has mobility issues.

However, a mattress that is too low to the ground can present other issues that make it difficult for someone with mobility issues to stand up from the bed. If mobility issues are a concern, youll want a total height close to that of most chairs which is about 20 22-inchs above the floor.

Whos Using The Mattress

This is one of the most critical factors to be considered while choosing the perfect mattress size. If you are an individual sleeper who does not share a bed with anyone, you can eliminate king and California king mattresses from your list queen, full, or full XL beds would likely be the most fitting. We recommend queen and full XL mattresses to those who prefer some space to sprawl, and full and twin XL options to sleepers who need to save space.

However, if you plan on sharing your mattress with a partner or child, youll want to choose a queen, king, or California king. If you and your partner like to co-sleep with your children, a king or California king would be better accommodating.

What Size Is A Twin Mattress

Some people incorrectly think a single bed is smaller than a twin. The terms are actually interchangeable for the same sized mattress. Standard twin mattresses are 39 inches wide. Regular twin mattresses are 74 inches long, and a twin XL mattress is 80 inches long.

Extra-long twin beds are commonly used in college dorm rooms. Theyre ideal for taller people who may not be able to accommodate a wider mattress in their space.

Room Size

A twin size bed, and even a twin XL, can comfortably fit in a 7-by-10-foot room. It can also fit in a smaller room of about 6.5 by 6.5 feet but note this room will not be to code when it comes to real estate. It would also be quite cramped and only be able to fit a small wardrobe and desk.

If you need to fit two single or twin beds in one room, it needs to be at least 9 by 9.5 feet. This minimum size doesnt offer much space between beds. Any added furniture, like desks or wardrobes, would need to be quite small.

If you have it, a 10 by 9.5-foot room or 10 by 10 room would fit two twin beds much more comfortably. Another way to fit two twins in a small space is to consider bunk beds. Kids bunk beds will need at least a 3-foot clearance, and theyre between 4 and 5 feet tall. The minimum ceiling height for kids bunk beds is about 7.5 feet.

For adult bunk beds, youll need a bit more clearance, and they run taller between 5 and 6 feet. Make sure your ceiling is at least 8 feet and 6 inches tall.
