Owning a suitable couple’s mattress provides both you and your partner a long, relaxing, restful sleep.
According to several studies, one of the most important factors in checking suitability is the bed size: if you’re sleeping with a partner on a bed size that does not isolate motion properly, chances are you are likely to have a bad time.
Though there are other factors besides size that are also important, bed size can be the leading factor as it’s simply one of those things that are a personal preference.
One of the reasons you and your partner probably are going to need a bigger bed is if one of you tend to sleep crossways or tend to do this in your sleep, as sleeping habits of partners play a critical role in deciding the size of bed that is best suited for them.
There are other ways to save money, but don’t go for a smaller bed hoping it’ll work out.
This will only cause the stress of having to choose different mattress all over again and going through (sometimes tedious) return processes.
You should also measure your bedroom space to see where the bed will best fit: measure if you will be able to open and close all doors, comfortably, and if you will be introducing additional items such as new furniture into the bedroom, etc…
It will be easy to choose a bed size that fits your bedroom if you think about the following questions:
- How much space should be left to be comfortable for walking around?
- How will you fit a couple’s bed in a small bedroom without making it look or feel cramped?
- What is the best size mattress for couples?
The Common Sizes of Beds for Couples
The following are the mattress sizes most commonly found online and in brick & mortar shops alike:
Twin and Twin XL
After the crib, Twin is usually the first size for young kids, which will stay with them for several years.
In fact, with a size of 38 by 75 inches, it will be long enough for kids up to their mid-teens and beyond.
The Twin XL variant, is simply a bit longer coming at 38 x 80, which fits taller kids and is commonly found in tight spaces like dorm rooms (by the way, check out our page dedicated to dorm room sheet sets).
Full/Double and Full/Double XL
The Full size (also called Double size) is a good choice for shorter people who don’t need much foot room, as with 54 x 75 inches is the same length as the Twin but a bit wider.
The Full XL (or Double XL) however gives you more foot room, measuring 54 by 80 inches, which is 5 inches more than the normal size mattress.
Although not very spacious, the Full XL size mattress can work for a couple where one or both of them are tall ( thus need an extra foot room) but don’t want the extra width that comes with a Queen bed.
This bed size also suits those couples who like to cuddle and don’t mind about needing personal space while they sleep.
Bedroom space should measure about 10’ by 12’ to 10’ by 16’ depending on preference for walking room.
This is the most common size bed in the world, big enough to fit two people comfortably, with each one having optimal room to move around and re-position, and also gives the opportunity to be close enough to one another for cuddling.
Standard queen bed size measures 60 by 80 inches, which is enough space to even have kids and pets sleep in occasionally.
Standard queen beds are popular in guest rooms and teenagers room.
Although not very large, it still requires adequate space in the bedroom to fit in, especially if two persons will use it.
You can check out our Best Mattress Guide for the top picks of this seasons in this size.
Although not very common in the US, sometimes people ask us about this odd size.
The Olympic Queen bed provides an extra 6 inches of foot space thanks to the measurement of 80 by 66 inches.
It is ideal for taller couples who also need the width to be bigger.
Olympic Queen bed should be fitted in rooms that have a longer length than width, usually measuring 10’ by 10’ to 10’ by 14’.
This bed size accommodates pets that love to lay on the end of the bed.
Also rare, the California Queen is for couples who need an extra space for movement, but don’t need added foot space.
This bed size measures 84 by 60 inches, which provides couples personal space while they are in bed.
One unique thing about California Queen size bed is its space can accommodate a child cuddling up next to the parents if the child wakes up at night.
The bed size fits bedroom space measuring 12’ by 10’ to 12’ by 14’.
Standard King and Split King
The regular King Size is very common after the Queen size.
This bed size provides the maximum amount of sleeping space and also gives more than enough space for other activities such as relaxing in a comfortable, stretched out position.
Standard King bed space is 76 by 80 inches, which is about as large as two twin XL beds combined, which is exactly how a Split King is usually made.
This variant has the advantage of being foldable, so it can be placed in rooms with tighter access.
Homes with larger bedrooms would benefit from this bed size or those couples who frequently share the bed with a child.
You can lay sideways to watch television or read a book. The possibilities with what you can do with the space in this bed size are endless.
The right bedroom space for this bed size should measure at least 10’ by 12’ to 13’ by 13’.
If you are looking for the longest size you can possibly get, California King bed is the one for you (also abbreviated to Cali King by the aficionados).
Measuring 72 by 84 inches, it’s for those who appreciate more length than width.
The bed measures 6 inches wider than a Queen bed, which provides couples more than enough room to sleep or cuddle.
This bed size gives couples optimal space for just about anything, and the kids or pet can occasionally jump in without compromising the space.
For the more creative, even a third person would fit in to sleep comfortably!
Motion Isolation Beds for Couples
Motion isolation is another important factor to consider when choosing a bed for couples, as it can be a nightmare if the mattress transfers motion to well instead of absorbing it.
If you are a light sleeper, you will feel the pinch of your partner constantly turning and tossing during the night.
Mattress for couples should have minimal motion transfer. Many modern memory foam mattresses handle this issue very well. It also keeps both you and your partner “in place” during the night.
Benefits of Having a Good Mattress Size for Couples
Couples owning a good mattress make their life simply better. Here is how:
Healthy, Restful Sleep
Having the right size bed, and having a mattress that isolates motion well, are some of the factors that provide a conducive environment for a couple’s restful, upbeat night’s sleep.
A night of good sleep translates to better health as you will be stress-free. You won’t be waking up every now and then because of your partner turning and tossing.
There is nothing more frustrating than having to move to use furniture to have sex with your partner just because the bed size is not fitting or conducive enough.
A good bed should have properties conducive or that promote better sex.
Not being able to have sex before sleep or when waking up in the morning can be frustrating!
Prevent Back Pain
In some cases, a mattress too small will force you into weird positions which could lead to back pain.
Of course there are many other factors leading to this type of issue (which we cover in our dedicated back pain page), but this is of those things so obvious that get ignored.
Ways to Fit Big Beds in Small Rooms
You have to get a larger bed if you are a couple, but your bedroom may be the limiting factor. Be smart and conserve space for a larger bed the following ways:
- Be organized: Use every inch of closet space to save space for a larger bed to fit in the bedroom.
- Eliminate the Dresser: You can eliminate that big chest of drawers, replacing it with a conventional bed frame with a platform bed that houses storage underneath. Store items from the drawers in the storage space underneath.
- Replace Swinging Doors: You can replace closet and bedroom doors with curtains to save space. Actually, a heavy fabric curtain also provides privacy and sound barrier in much less space than swinging doors and closet.
The Best Bed Size for Couples: There Isn’t a Perfect Model
As with so many things, there is no perfect bed size as it’s a very personal matter.
Not only it’s a matter of taste, but also a matter of space, so there are a lot of possible combinations.
In summary, we’d say that you should get the largest mattress possible considered your room size and your body size.
Believe us: it’s better to sleep with a couple inches to spare than having to regret your stingy choice every night!
