Twin XL Mattress vs. Full/Double Mattress

Quick Overview

There are several factors to consider when deciding on the best mattress size, including bedroom size, shopping budget, and the number of people who plan to sleep on the bed. Most mattresses sold today are available in six standard sizes: Twin, Twin extra long (XL), Full/double, Queen, King, and California King. Additionally, select brands and models offer specialty and custom sizes.

This guide will compare the Twin XL and Full/Double sizes. To start, let’s look at the basic differences between these two sizes.

Key Differences and Similarities Between Twin XL and Full/Double Sizes

The table below highlights key aspects of Twin XL and Full/Double mattresses.

Mattress SizeTwin XLFull/Double
Standard width38 in.54 in.
Standard length80 in.74 to 75 in.
Ideal bedroom sizeMinimum: 7.16 ft. wide x 10.66 ft. longMinimum: 8.5 ft. wide x 10.25 ft. long
Average price$500 to $750$550 to $800
Ideal sleeping arrangementSingle sleepers who are too tall for a standard Full/Double, but do not require extra sleeping space in terms of mattress width.Single sleeper who is average height and prefers some extra sleeping space.

Pros and Cons of a Twin XL Size

A Twin extra long, or Twin XL, measures eighty inches (80″) long, which is five inches (5″) longer than a standard Twin and Full/Double; both a Twin and Twin XL measure roughly thirty-eight inches (38″) wide. The Twin XL is equivalent to one-half of a standard king-size mattress (76W” x 80L”), and is ideal for sleepers who are too tall for a standard Twin-size mattress. However, the Twin XL is usually too narrow to accommodate more than one person.

Benefits of a Twin XL mattress include the following:

  • Less space required:Although a Twin XL is five inches longer than a Full/Double, they take up less overall space. A Twin XL measures a total of 3,120 square inches, while a Full/Double measures 4,050 square inches. This makes the Twin XL more suitable for narrower bedrooms.
  • Lower price-point:A Twin XL mattress is normally priced $50 to $300 lower than a Full/Double version of the same model. In rare cases, the Twin XL and Full/Double sizes will share the same price-point.
  • Long enough for most sleepers:A Twin XL will accommodate anyone who stands at 6’7″ or shorter; in contrast, the Full/Double will be too short for anyone who stands 6’3″ or taller.

Some drawbacks of a Twin XL mattress include the following:

  • Less width for single sleepers:A Twin XL mattress is roughly sixteen inches (16″) narrower than a Full, and is not ideal for single sleepers that prefer extra space.
  • Not couple-friendly:A Twin XL measures roughly thirty-eight inches (38″) wide, making it too cramped for most couples.
  • Limited availability:Although Twin XL sizes are fairly common, this size is not as widely available as the Full/Double size.

Pros and Cons of a Full/Double Size

Also known as a Double, the Full-size mattress measures fifty-four inches (54″) wide by seventy-four to seventy-five inches (74-75″) long. The Full/Double is ideal for individual sleepers who require a wider sleeping space. For this reason, Full/Double beds are often used in hotels and motels, college dorms, healthcare facilities, and other commercial establishments. Like the Twin XL, Full/Double beds are typically not suitable for couples.

Benefits of a Full/Double mattress include the following:

  • Extra space:A Full/Double mattress is five inches (5″) shorter than a standard Twin XL, but the size is roughly sixteen inches (16″) wider. For this reason, a Full/Double is suitable for single sleepers who feel too cramped on Twin XL sizes.
  • Wide availability:Most mattresses sold today are available in a Full/Double size, including models that are not offered in a Twin XL.

Drawbacks of Full/Double mattresses include the following:

  • Higher price-point:The average Full/Double mattress costs $50 to $300 more than a Twin XL version of the same model, though some brands assign the same price-point to Full/Double and Twin XL mattresses.
  • Not long enough for exceptionally tall people:While a Twin XL is suitable for anyone who stands under 6’8″, a Full/Double is too short for anyone who stands at 6’3″ or taller.
  • Not couple-friendly:Like the Twin XL, a Full/Double will be too narrow for most couples to sleep comfortably, and should be considered suitable for single sleepers only.

Is a Twin XL or Full/Double Size Right for You?

Do you sleep alone or with a partner?

When deciding between a Twin XL or Full/Double mattress, you should first decide who will be sleeping on it. If you’re a single sleeper, a Twin XL will be comfortable. If you sleep with a partner, the extra space on a Full/Double mattress will help both of you get into a more comfortable sleeping position. Twin XL mattresses are ideal for temporary sleeping arrangements, and for single teenagers who don’t share their bed with a partner. If you don’t have plans to sleep alone, consider moving up to a Full for comfort’s sake.

What is your body type?

A Twin XL mattress can sleep a single adult or generally most body types. From heavier sleepers to lightweight bodies, a Twin XL is ample enough for a regular sleeper who doesn’t need to stretch or move around the bed frequently while resting. If you have a large body type or require more legroom, a Full/Double mattress will feel much roomier than a Twin XL. The same goes for your height. The taller you are, the more a few extra inches at the feet become welcome.

Do children and/or pets frequently share your bed?

Pets are often welcome additions to the sleeping environment, so long as they fit. Sleeping with animals can disrupt your sleep, especially when they take over the bed. The same goes with children who curl up in their parent’s bed. A Twin XL is probably better suited for a single adult with a small pet or child. A Full/Double mattress can comfortably fit pets, small children, and up to two adults. If you enjoy snuggling up for family time on your bed, plan to size up so that everyone can get a good night’s rest.

How do you position your body when you sleep?

Sleeping on your side, back, or stomach means you’ll have different mattress needs. Depending on how you like to fall asleep, a larger mattress may or may not be something you need. Back sleepers usually stay in a more narrow position, although if you’re tall you might require more length. Stomach and side sleepers will have more room to sprawl out their hands and legs on a Full/Double mattress than they would on a Twin XL.

How much bedroom space do you have?

No matter which mattress you like best, it ultimately will have to fit your living space. Both Twin XL and Full/Double mattresses are suited for standard size bedrooms. Both of these mattress sizes are ideal for shared guestrooms and children’s rooms. If you live in a studio apartment, both the Twin XL and Full/Double options will leave you will enough room to add some more furnishings as well.

What is your mattress shopping budget?

Larger mattresses always cost more than their smaller models, so if budget is a concern you might choose to stick with the Twin XL instead of buying a more expensive Full/Fouble mattress. Keep in mind prices for mattresses vary significantly based on the mattress brand and special features. If you’re willing to choose a lower-cost model you can shave off some of the additional expense of upgrading sizes.

Once you’ve set your expense cap, you can begin shopping. Be sure to pay attention to specialty mattress sales and events to find the perfect mattress for your budget and needs.


The choice between Twin XL and Full/Double mattresses is essentially a trade-off. The Twin XL is a slightly longer option that is suitable for anyone who stands at 6’7″ or shorter, while the Full/Double offers a more expansive sleep surface that is sixteen inches (16″) wider.

Prices are usually negotiable between the two sizes, and neither one will usually cost more than $800. Neither the Twin XL nor the Full/Double are intended for use by more than one sleeper, though — in a pinch — both can accommodate two sleepers with very limited sleeping space.

It’s important to note that these findings are largely subjective. If you are unsure which size will work best for you, we recommend testing both the Twin XL and Full/Double sizes in brick-and-mortar mattress stores. In addition, mattress sleep trials allow you to sleep on both sizes in the comfort of your own home for prolonged periods of time. Simply return the size you are least satisfied with before that sleep trial ends.

          Twin XL vs. Twin Bed Size: Things to Consider When Purchasing

          When it comes to furnishing your guest room or your kid’s one, the choice might seem quite easy – right? Well, you’d better think again. Are you purchasing atwin-sized or a twin-XL one? There is a size difference between these mattresses, and you should be aware of it.

          Want to learn about even more sizing differences? This post covers all the different mattress dimensions available.

          While both solutions are typically designated for those exact purposes, the difference could turn out to be quite substantial. This is why it is incredibly beneficial for you to be perfectly aware of what separates those beds to make an informed choice.

          This is why we’ve decided to provide you with a detailed overview of both types and see how they stack against each other. The hope is that you’ll be able to differentiate between them easily and, ultimately, make the best call when the time comes to purchase one. So, without any further ado, let’s dive right into it.

          Twin vs. Twin XL Detailed Comparison


          Obviously, as you can probably figure it out from the name, the size difference between the models is the main factor when purchasing one of these beds.

          Starting off with the regular twin mattress, it measures 38 x 75 inches, making it one of the most common choices for kid’s rooms. They would usually outgrow the length when they hit high-school, and that’s when their parents would consider buying a new, larger mattress. Up until then, it’s a great solution as it’s space saving and it allows you to furnish the kid’s room with a lot of different accessories.

          The extra long Twin measurements, on the other hand, are also quite convenient for a kid’s room, even though people often use it for a college room bed or a guest-room solution. The reasons are simple – it’s almost as space-saving as its counterpart, but it is capable of accommodating the higher length of older people. It’s as simple as that.


          In terms of comfort, both mattresses perform comparatively the same given their intended purposes. A twin bed would be ideal for a small kid up until he or she outgrows the length, making it the best choice for your kid’s room. They are also quite affordable so investing in one wouldn’t disrupt your personal finance.

          On the other hand, the added comfort of the 5 extra inches in the length of the twin XL makes it perfect for college rooms and guest rooms. This is because they would accommodate people who can be over 6 feet tall and their feet wouldn’t have to be hanging loosely in the air.


          The prices are a bit different with the twin XL being a bit more expensive. However, this is only related to the bed itself as well as some serious spare parts such as frames, springs, and others of the kind.

          When it comes to the accessories as well as the sheeting for the bed, it’s fair to say that there is no significant difference. While twin bed XL accessories tend to be ever so slightly more expensive, it’s not a difference that would ultimately determine your overall choice. Therefore, this is not a differentiating factor that you ought to account for as it certainly won’t make a serious difference.

          Recommended Room Size

          This is another thing that you would have to account for when you’re making the call. The recommended room size for a regular twin size bed is 7 x 10 feet or 10 x 10 feet if you have two of those fit in the same room. If you have a twin XL mattress, you can fit one within 7 x 10 feet, but you’d be jeopardizing on the length quite a bit, leaving you with less room to maneuver.

          Twin Bed Pros and Cons

          Twin mattresses come with a slightly shorter length which is the main differentiation. They do, however, have a lot of benefits.

          • It’s a very common and easy to shop for bed size
          • It’s quite affordable
          • It’s available and fits almost any room size
          • It is very easy to move around
          • It is way too narrow for two people
          • It may be slightly shorter for adults or taller teens

          Twin XL Pros and Cons

          The twin size XL reveals a 5-inch length difference which may just be the turning stone when you make your final call.

          • It allows more foot space
          • It is virtually the same price as a twin-sized bed
          • It is quite easy to move around
          • Requires more length of your room

          Our Final Thoughts

          If we’d had to choose a mattress between both of these right now, the purpose of it would be the main differentiation criteria. Since you can always sacrifice 5 inches of length in your room, the only thing that would really make a difference is who would be sleeping on that bed.

          If you are looking for a single bed for your only child who’s just turned 2 years of age and is ready to sleep independently, the regular twin mattress would be a great option, provided you don’t have the extra room.

          If you have the extra room, however, or you are looking for a quick and space-saving solution for a college room or a guest room, the twin XL is the most obvious option that we’d prefer to stick with every day.

          As you can see, the choice is really not that hard, and all you have to do is make up your mind regarding the use of the bed. It’s that simple. We hope that you’ve found those mentioned above useful and that you can easily make up your mind without wasting hours in searching.

          Why Buy A Twin XL Mattress?

          You would want to buy a twin XL mainly for the length. A twin size mattress is only 75” long. Taller children and teens might need those extra inches with the Twin XL. Plus, your child or teen may not have the space in their bedrooms to fit a queen size or king size bed. Also, most college dorm rooms have twin XL mattresses. So if you’re a college student who isn’t too keen on sleeping on that awful, springy, plastic-covered dorm bed, you might want to find a whole new mattress. And since those bed frames already accommodate a twin XL size, that’s pretty much what you’ve got to go with. Keep in mind that this will also apply to mattress toppers and sheets.


          BEST FOR:

          • Anyone that likes memory foam
          • Back, side, stomach, and combo sleepers
          • Individuals that weigh under 230 lb

          Nectar is a bed-in-a-box mattress brand that’s up there with Casper and Purple in terms of popularity. This is a multi-layer memory foam mattress that’s about a medium to medium-firm in terms of its day-1 firmness rating. As you can see in the chart below, however, we see firmness on a continuum, so if you’re buying for a kid the mattress will probably feel more like a medium-firm, at least for the first few months while they break it in.

          If you like memory foam (or are open to it) you will likely find this to be a comfortable mattress. You sink in—particularly around your shoulders and hips—creating a little cocoon that makes you feel secure and content in the mattress. In other words, this is not your throwback memory foam mattress.

          A lot of people will really enjoy the Nectar mattress

          For individuals that weigh under 230 lb (maybe 250 lb), the Nectar Sleep mattress should do the trick. And, given its firmness level, this will be a nice mattress for all sleeping positions (back, stomach, and side). The bottom line with this bed is that it’sfor individuals that like memory foam, are on a budget, and need an accomodating mattress.

          BEST FOR:

          • If you want to select the firmness level for your new bed
          • Anyone that wants an American-made product backed by a lifetime warranty
          • People that want/need a general soft-foam bed
          • Back, stomach, and combo sleepers

          The Love & Sleep mattress for Nest Bedding isdesigned to attract budget shoppers and yet, it’s still backed by a lifetime warranty. Even more, it’s available in two firmness levels (Medium and Firm) so that you can select whichever you think is best for you.

          As for how the mattress feels, it’s fairly neutral (i.e. it does not have a memory foam feel). In fact, it feels like a generic slab of foam that’s either firmer or softer depending on which firmness level you select.

          One interesting feature about the Love & Sleep mattress is that it has a special cover which incorporates a phase-change material to help regulate temperature. We wouldn’t consider this a proper cooling bed, but it’s not something that will cause you to drown in sweat in the middle of the night. Love & Sleep is one of very few lower priced beds that has this sort of cover.

          Love & Sleep has a neutral, accommodating feel

          Our experience with the mattress has been that it’s best for back and stomach sleepers, though, individuals that weigh closer to 200 lb can get by on their side. And, keep in mind that all beds soften the more that you sleep on them. The Love & Sleep mattress reminds us a lot of the Tuft & Needle mattress, although, it’s slightly thicker and more expensive. I mention this because Tuft & Needle is an alternative to Love & Sleep if you prefer to shop for an Amazon mattress.

          Lucid Hybrid

          BEST FOR:

          • Petite, medium, and even heavier people
          • If you want a bed with a neutral feel and a hint of memory foam
          • Back sleepers, side sleepers, stomach sleepers, and people that rotate positions at night

          For anyone that weighs around 200-250 lb and is on a tight budget, the Lucid Memory Foam Hybrid is hard to beat, especially if you like shopping on Amazon and want a bed that’s in the middle in terms of firmness. This will be a great option for college students and heavier kids that need a bed with a little more support.

          This is one of few hybrid budget-level beds

          The mattress has more of a neutral feel, though, you can tell it does use memory foam. That said, it’s still responsive and rotating sleeping positions takes hardly any effort.

          In terms of firmness, we’d set this at about a medium, give or take. For petite individuals it will feel firmer, and for heavier individuals it will feel softer—that’s the case with all beds. Still, we don’t see hardly anyone saying that this is a “soft mattress” or a “firm mattress.” It really is in between, and we think that’s a good thing.

          What sets this apart from a lot of cheaper mattresses is that it has a base layer of coils, not foam. This provides bounce and support, and means that the bed should be far more durable over the long run than a comparable foam bed. This is the reason that we think it will be a wonderful option for bigger kids, teens, and college students.

          How Do We Know?

          Here at the Slumber Yard, we’ve reviewed dozens of mattresses. We’ve got the cheapest beds on the market, to some of the most luxury mattresses, and everything in between. If you’re looking to invest at or under $1,000 on your sleep experience, you’ve come to the right place. Heck, even if you’re only looking to spend under $500 on your new bed, you’ve come to the right place. We tend to take into account the small details that the average consumer may not even think about when shopping for a new bed, such as edge support for couples that like to spread out, mattress weight for people who move frequently, or if you can still get that latex mattress if you have a latex allergy (spoiler: you probably can). We also have a very diverse set of team members here at the Slumber Yard, that vary in shape, size, and sleeping position, so that we can appeal to almost anyone.

          What Is A Twin XL Mattress?

          A twin XL mattress is just like a twin mattress, but longer. A twin size is the smallest bed available on the market, and is typically used for children and teenagers. A Twin XL has about 5 more inches tacked onto the end of the bed, because sometimes our teens grow taller than us. A Twin XL is 39” wide by 80” long, which is exactly tall enough for someone who is 6’8”. Here’s a chart with the dimensions of all the most common sizes, incase you want to compare mattresses.

          Typical Twin XL Mattress Pricing

          A twin XL mattress is typically always going to cost a tad bit more than the twin mattress. On the budget end of the spectrum, we found twin XL’s for about $120 from Linenspa, and then at a more premium level like Avocado, they’ll cost you up to $1,000. A middle ground price would be around $645, which is what Casper offers.

          Now, while we do understand wanting the finer things in life, do keep in mind that twin XL mattresses are usually used for teens, college students, or guest bedrooms. Teens and college students will eventually grow out of this mattress, so just think realistically about how many years you’ll get out of this bed before needing to upgrade to a larger size. Then, after you think about that, decide how much you want to spend on your new twin XL mattress.

          Your Body Type

          Body type and weight plays a big part in how you will perceive your new mattress, because unfortunately, there’s no one size fits all when it comes to beds.

          A basic rule of thumb is that the larger the body type and/or the heavier you are, the softer the bed will feel for you, because you’re exerting more weight onto it, and sinking in more. On the opposite side of that, the less you weigh and/or the smaller body type you have, the firmer the bed will feel to you, because you’ll be laying more on top of the bed, rather than sinking in.

          For this post, we assume that most people sleeping on a twin XL are doing so because they have a tall frame, which means they might be on the heavier side. Keep this in mind when you buy a new mattress that’s on the firmer and/or thicker side.

          Your Sleeper Type

          How you sleep also has a big impact on which mattress is right for you. Most people fall within the category of side sleepers, back sleepers, stomach sleepers, or combination sleepers (which means you switch positions through the night).

          Side sleepers generally need a softer mattress that will provide pressure relief for their hips, neck, and shoulders. If a bed is too firm, it can leave you with a pins and needles feeling because of a lack of circulation.

          Back and stomach sleepers are the exact opposite. They need a firm surface that will support the heaviest points of their body, which is the head, shoulders, and hips. If a bed is too soft, it’ll let the hips and shoulders sink too deep into the surface, which will make the spine curve or arch, which can lead to aches or soreness.

          Combo sleepers are a little more difficult. We recommend either going for something with a medium firmness, or catering to the position you predominantly sleep in.

          Intuitively, the different sizes of beds seem easy enough to understand, right? The truth is,choosing the right size of your mattresscan be more complicated than you may think. Does it fit nicely in my bedroom? Is there enough leg room? And many other.

          To help you make the best decisions when selecting a mattress, we’ve put together a summary of the most common measurements you will see online and in a store so you can have an idea if it’s a perfect bed for you and your bedroom.

          What is important to note about a Twin bed versus a larger toddler bed, is that comfort is taken more into account. It’s common that, once you reach the Twin size, more quality materials are used, and more engineering centered on comfort takes place. This is because, the older we get, the more we consider comfortable sleeping to be a necessity.

          Twin XL

          There are subcategories of double beds to consider as well. The Twin XL istypically 80” L while still maintaining the 38” W. If you’re an adult looking for a bed that saves space and still is a comfortable choice, an XL Twin may be perfect for you.

          Can I use Twin XL mattress on a King Size Bed Frame?

          Yes, you can use two double/twin XL beds in a king frame. If you are in a relationship where one partner requires a different firmness than the other, usually end up being big fans of this setup. This is because Two XL beds can fit snugly alongside each other within a King sized bed frame.

          This is good to know for partners who are tired of the fluffiness or firmness of their spouse’s mattress.

          Full Bed Dimensions

          Full-size mattress measures54’ width x 75” in length, and these are also commonly referred to as “standard double.” Sufficient for adults that need more room than what a Twin can offer.

          If you are in a relationship, this may not be the best choice for you, as the fit will be exceedingly tight. Likewise, if you have a dog, cat, or you have a child that sleeps next to you, you may want to consider a wider option.

          Full (Double) XL

          A XL option is54” x 80”giving you anextra 6 inchesof leg space. If you do not require extra width but want some more room for your legs this is a perfect option.

          Queen Bed Dimensions

          Queen size mattresses are60” width x 80” length. Ideal for almost anyone, in that it’s long enough and wide enough to suit most any sleeper. For those who sleep with their spouse, child or pet, it might be perfect for you.

          When thinking about these larger types, it becomes necessary to consider the living space. These take up much more room than the Twin or the Full, and thus, the ability to freely move around the bedroom may become restricted.

          If you have a larger bedroom, then this won’t be a factor for you.

          Olympic Queen

          These are slightly wider andmeasure at 66”W x 80” L. Olympic queen is perfect for taller individuals, but you don’t want to upgrade all the way to King, but you could use some more width.

          If you want to compare this to other options,King is same as 2x Twin XL.

          A nice fact is that box springs are split for this type, and it makes it easier to carry around and maneuver.

          California King Bed Dimensions

          Bedroom Size Requirements

          Ok, so you have decided that you need a new bed. But, can you actually put it in your room and still be able to open the door and walk around it?

          Let’s take a look at the following illustrations showing how certain mattress sizes will fit in your room.

          Frequently Asked Questions

          Which size is best for me?

          Bigger isn’t always better, but in most cases it can’t hurt. More space could mean fewer sleep interruptions, but if you always prefer to cuddle up rather than spread out, that extra space might not be worth it, especially if you’re on a tight budget.

          In many cases, couples will opt for a bigger version of a cheap bed, but if you don’t need the extra space, that money could be better spent on features like cooling or motion isolation. For a better understanding of getting your money’s worth, take a look at our mattress budget guide .


          When trying to find the right mattress size to fit the needs of you or your family, these are a few things to have in mind.

          • First, if you’replanning on upgrading, make sure you know the dimensions of your current bed. You wouldn’t want to shop for a larger option and accidentally choose the same type.
          • Second,if you’re moving, don’t forget to measure the room that you’ll be sleeping in. It is awful to have a mattress that is too big for space. You’ll have issues getting around the room, and your space won’t be as aesthetically pleasing.
          • Third,who will be sleeping in it? If it’s just you, you are good to go with a Double. But, if you have a spouse, kids or pets you might want to opt for a larger option such as Queen. King is the ultimate comfort size if your room can accommodate it.

          Now that you know more about the sizes you can check out our other guides, researched for specific needs and types.

          Hope this guide was helpful and that it cleared any doubts.
