For many Americans, the twin and twin xl constitute their first foray into the world of mattresses. The twins often feature in the bedrooms of children and teenagers, and for many, a twin is typically their first real bed.
Hence, the chances are that if you are shopping for twins, you are looking for a suitable mattress for your children’s room. However, with Twin and Twin XL mattresses, like with other mattress size comparisons, the choice is not always clearcut, and there is more than what meets the eye at first glance.
Which option should you pick for your teenage child? Could an adult use a twin or a Twin XL comfortably? How much room do you need to fit a twin or twin XL mattress?
Read on to get the full scoop about these mattress dimensions, their differences, best use cases, and check out our top-rated picks for both form factors.
Twin vs. Twin XL: Overview
With twins and the more substantial twin XL mattresses, there is no confusing their purpose. Both beds feature proportions that make them excellent for use by a single person.
With either option, you get a slim profile that provides just enough space to accommodate one person comfortably. However, both mattresses differ in their lengths. A Twin XL brings an extra 5 inches over the standard Twin, providing a crucial additional room that can make a world of difference, especially for adults and taller children.
Nevertheless, both mattresses make excellent choices for kid’s rooms as they are the perfect size for an independent bed.
A Twin XL, however, provides even more versatility. Since a Twin XL can fit most average size adults comfortably, it makes an excellent bed for college rooms, guest rooms, or other locations with limited space or where space savings is the top priority.
From their naming system, it is immediately apparent that the Twin and the Twin XL are quite similar, and their dimensions echo the same sentiment. With either mattress, you get the same width, while the XL brings an extra 5 inches in length.
A standard twin mattress measures 75 inches in length and has a width of 38 inches, which a height profile that can vary from product to product. With the Twin XL, however, you get a length of 80 inches, which provides significantly more room, excellent for fitting taller kids or adults.
Pros And Cons
For people deciding between a Twin and Twin XL, the identical width of both mattresses means that you only have to decide on which length is best for your use case.
Furthermore, since both beds are relatively more compact than the other mattress dimensions, you rarely have to worry about space management. Plus, the five-inch length difference between both options is not going to take up much more of your floor space and, hence, it won’t be a significant consideration for most people.
So, what changes should you expect with the extra 5 inches on the Twin XL?
The additional length on the XL is crucial as this small bump elevates the Twin from a children-only bed to one that will fit most adults.
The standard Twin’s Twin’s 75-inch length is too short to fit adults that measure at least 5’9 in height. Additionally, even for children, a Twin XL can be the safer choice as it is significantly more future-proof and better equipped to handle all of your kid’s growth spurts.
However, both mattress sizes are terrible options if you plan to fit a couple, as supporting more than one person on their only 38 inches of width will be a near-impossible task. Here, you are better off opting for broader alternatives like a full size or a queen.
Aside from the difference in length, for Twin and Twin XL mattresses, other variables like firmness and accessories are typically comparable for offerings from the same brand.
- A tiny footprint that will work in most rooms
- The small size works great for bunk beds, perpendicular arrangements, and other children room or guest room setups
- Compact and easy to move around
- One of the least expensive options for your children room
- Too small for adults or tall teens to fit comfortably
- Less future-proof than an XL for growing children
- Small width can be a bit restrictive, even when sleeping one person
- The smallest footprint of any bed that would fit an adult
- The extra length gives kids more room to stretch out and makes the bed conducive for adults and tall teens too
- Compact and easy to move around
- The more future-proof option for growing children
- You can make two Twin XLs into a king size by placing them side by side, providing an alternative use for them when the kids leave home
- The extra length will be unnecessary for most children, especially considering the often slightly higher cost of this mattress size and its accessories
- Small width can be a bit restrictive, even when fitting one person
Room Size Recommendations
If you plan to fit a single Twin or Twin XL in your living space, you rarely have to worry about room sizing recommendations. The tiny size of both mattresses means that, for most homes, either bed will slide right in without any space issues.
However, where things begin to get complicated is when you need to incorporate multiple beds, a common occurrence in children’s rooms and dorms, where these mattresses often feature.
When using two or more Twin or twin XL beds in a space, you must factor in providing sufficient personal space for each child. A good rule of thumb to follow is to allow at least 4 feet of distance between the open end of each bed. However, adding even more space if the room size will allow it is preferable.
Furthermore, you must factor in allowances for other bedroom furniture like dressers, chairs, and desks before choosing to go through with your setup.
In most cases, you will need a room that is at least 10 feet by 8 feet to fit two twin or Twin XLs placed side by side and accommodate both room inhabitants comfortably.
Another everyday use case for twin XL mattresses is making a king bed out of them by placing two units side by side. In this case, you should follow standard room size recommendations for a king-size mattress, which is a space of at least 10 feet, 5 inches by 9 feet.
Price-wise, both Twin and Twin XL mattresses are generally on the low end compared with other mattress sizes. Hence, the chances are that if you are shopping in this segment, you won’t be breaking the bank.
Nevertheless, like with most other sleeping products, across brands, prices can vary widely, with everything from basic 100-bucks offerings to more premium feature-packed options.
However, if you are comparing prices within one brand’s catalog, for mattresses with an identical feature set, you should expect to pay a small premium for a Twin XL over a regular Twin. Typically, price differences between both options will range between $50 to $150.
Similarly, when it comes to accessories like sheets, comforters, box springs, and bed frames, you should expect to shell out a few extra bucks for Twin XL fittings.
Should I get a Twin or a Twin XL Mattress?
While both twin and Twin XL mattresses make excellent children’s beds, the extra length of the XL can be a game-changer in many situations. With the Twin XL, you get more future-proofing to cover your kid’s growth and the added versatility of fitting an adult if the need arises.
However, in many cases, the extra length of the Twin XL is not necessary. You should consider getting a twin if:
- You only need to fit your kids for a few years and don’t have to worry about them outgrowing the bed
- You have minimal floor space and every extra inch counts
- You would instead create more personal space for your kids than provide a few extra inches of bed length
On the other hand, we recommend making the jump to a twin XL if:
- You plan to have a rapidly growing kid that could quickly outgrow a standard twin
- You need a space-conscious option for a college student
- You plan to fit an adult
- You do not have any floor space concerns
- You want to provide your kids with as much room as they need to stretch.
