If you want to get an all-inclusive view into all sizes of beds on the market, this is your ultimate guide. 

I’ll list all the key features of every all mattress sizes in order so you know what you’re getting into.


typical crib bed size

  • Dimensions: 27 x 52 inches
  • Mattress thickness: 2–6 inches
  • Mattress weight: 7–25 pounds
  • Price range: $100–$1000

Crib beds are the smallest among the standard sizes on the market. 

They’re meant for babies and toddlers, and they can fit into virtually any room, thanks to their small size. 

On top of that, they have no headboard, which allows you to hang wall decor above them comfortably.

Crib beds’ prices can go anywhere from $100 to $1000, depending on what you want.

You can find pretty solid options in the $200–$500 range.

The main disadvantage of these beds is the bars on their sides.

They make it hard for you to make the bed and replace the linens.


twin bed size ex

  • Dimensions: 38 x 75 inches
  • Mattress Thickness: 5–8 inches
  • Mattress Weight: 40–45 pounds
  • Price range: $100–$3000

Twin beds are suitable for kids, at least until they grow up.

A kid can sleep on them until his teenage years, and then they’ll be a bit too short and slim.

The benefits of twin beds are countless. Here’s why:

They’re slim, so you can fit multiple beds in one room. On top of that, you can place absolutely any rug under them. 

Most standard rug sizes will work, thanks to their compact dimensions.

Moving on to the disadvantages, twin beds don’t allow for many pillows.

You can get one large pillow on the bed, not more than that. 

These beds typically cost between $200 and $1000, and more expensive options come with mattresses included.

Twin XL

  • Dimensions: 38 x 80 inches
  • Mattress Thickness: 5–8 inches
  • Mattress Weight: 43–48 pounds
  • Price range: $200–$3000

Twin XL beds have the same width as twin beds, but they’re a bit longer for older kids. 

They’re mainly meant for school dorms because they’re compact and easy to move around.

These beds are highly convenient because they save space yet allow a comfortable sleeping room. 

They also allow for bedside tables because they’re slim, and you can place rugs under them comfortably. 

If I were to list their disadvantages, I’d say they don’t fit multiple pillows because they have the same width as twin beds.

Full or Double

double bed size ex

  • Dimensions: 54 x 75 inches
  • Mattress Thickness: 8–20 inches
  • Mattress Weight: 50–60 pounds
  • Price range: $300–$2000

Full beds are ideal for adult single sleepers.

They may fit a couple, but there won’t be enough room for comfortable sleeping. 

Still, they’re a good balance between twin and queen beds.

Plus, they allow for multiple pillows, and there are endless linen options on the market.

While you may face difficulty buying linens for some large-sized beds, full-size beds are easy to shop for. 

The main disadvantage of full beds is that they may be considered short for tall users.

They aren’t as common, but you can also get a Double XL bed, which is just a bit longer at 80″. 

This makes it easier to use a full to sleep a taller adult.


queen size bed ex

  • Dimensions: 60 x 80 inches
  • Mattress Thickness: 8–20 inches
  • Mattress Weight: 120–160 pounds
  • Price range: $300–$3000

Queen beds are the standard choice for couples, and they’re the most popular beds in the US. 

Their dimensions are convenient for small rooms yet large enough to allow couples comfortable sleeping. 

They’re also large enough to use decorative pillows plus your regular sleeping ones. 

Because these beds are popular, you’ll be able to shop for linens, pillows, and accessories easier than ever.


king bed size ex

  • Dimensions: 76 x 80 inches
  • Mattress Thickness: 12–20+ inches
  • Mattress Weight: 130–180 pounds
  • Price range: $500–$4000

King beds are precisely double the size of twin XL beds.

So, for a couple, each one gets to sleep in a bed of their own with ample legroom. 

Needless to say, these beds are highly comfortable, but they need large rooms. 

In most cases, you’ll want to check your master bedroom size to see if the dimensions of this larger bed fit practically there.

Aside from that, they’re hard to move around, and their linens may be a bit costly.

The cheapest options may exceed $100.

You’ll also need to put a lot of thought into decorating the room. 

There may not be enough space for bedside tables, and the headboard will likely eat up the wall, not allowing for wall decor.

The good news is, you’ll be able to put as many pillows on the bed, thanks to its size. 

It may be a bit tricky to adjust the linens, though. You’ll have to go around the bed multiple times!

California King

  • Dimensions: 72 x 84 inches
  • Mattress Thickness: 12–20+ inches
  • Mattress Weight: 150–200 pounds
  • Price range: $500–$5000

California beds are considered larger than king beds because they’re taller. 

However, they’re actually slimmer, so they offer less sleeping room than the former. 

These beds are mainly for tall users who won’t be comfortable in an 80-inch mattress. 

They’re convenient because they fit better in smaller rooms, unlike king-size beds.

In addition to that, they allow for bedside tables because they’re slimmer.

Still, it would help if you put some thought into the room decoration, including the rug placement and wall decor. 

Here’s why it’s not easy to decorate a room with California beds:

  • Their length takes up most of the room
  • Most standard rug sizes won’t fit underneath
  • Most of them have extra-large headboards

You should also bear in mind that making California beds is a bothersome process. Not that in most cases a king sheet set will fit a Cal King bed.

Due to their length, adjusting the linens won’t be a piece of cake.

Believe it or not, there are even larger beds than this (well, at least mattress sizes).

The Wyoming King comes in at an impressive 84″ x 84″, and is a true-square bed sizes.

Larger even than the Wyoming is the biggest whopper of them all: the Alaska King bed. 

The Alaska is also a square bed that measures 108″ x 108″.

This is the only mattress that can almost comfortable sleep four adults. Finding sheets and comforters for this bed is hard, to say the least.

Different Types of Beds and Their Sizes

Aside from the standard bed sizes you find on markets, there are different bed sizes depending on special purposes.

Here’s a list of them.


day bed size ex

  • Dimensions: 42 x 78 inches (average)
  • Price range: $200–$2000

Daybeds are typically made for guest rooms, living rooms, and maybe home offices. 

They’re not meant for sleeping—they’re more of hybrids of sofas and beds. 

They serve well for decorative purposes, but they’re not functional when it comes to sleeping, unless then convert into a full-sized bed.

Some twin-size daybeds can double as sleeping beds, making them convenient for tight spaces and guest rooms.

Fold-up Beds

  • Average dimensions(Folded): 31W x 11L x 40H inches
  • Price range: $25–$2000

Fold-up beds are mainly convenient for guest rooms.

If you don’t have enough room for a full-fledged bed, a foldable one is always a good option. 

It may also be ideal for student dorms and tight apartments with multiple tenants.

Just like with fold-out sofa beds, there are multiple sizes available of fold-up beds, from twin size and up to king-size beds.

Bear in mind that you’ll need a foldable mattress for a fold-up bed.

Most of them already come with mattresses, but it adds to the cost.

Cot Beds

cot bed example

  • Dimensions: 29 x 58 inches (for kids) and 30″ x 80″ (on average for adults)
  • Price range: $100–$1000

Cots beds are great for having something small to bring out of the closet for guests or while traveling.

You probably know them most for their portability when camping.

These types of beds can also be similar to cribs, except they would be meant for toddlers as they wouldn’t have sides.

They also offer a larger sleeping room than cribs, making them more convenient for bigger kids. 

Some cot beds need mattresses that measure 28 x 56 inches on average, but it depends on the size you get.

Otherwise, cots are their own mattress as they support the weight of a person comfortably enough for temporary sleeping situations.

Inflatable Beds

  • Price range:

Inflatable beds are meant for camping and outdoor activities.

They’re not too comfortable to sleep on, but they have multiple benefits. 

Here’s why inflatable beds are highly convenient:

  • Easy to use 
  • Lightweight
  • Easy to store
  • Affordable

They’re also available in all sizes with different weight limits. Some options can carry up to 600 pounds.

Air mattresses are another type of inflatable bed designed for a quick “instant” bed for indoors, usually for guests. They come in every standard bed size, from Twin to King.

RV Beds

rv bed sizes

There are multiple types of RV beds, depending on the size of your trailer and your budget. 

Here’s a brief list:

  • Sofa beds
  • Convertible dinettes
  • Bunk beds

For starters, sofa beds work perfectly well for RVs.

They don’t take much room, and they can be used for sitting during the day.

There are also convertible dinettes, which are initially tables that convert to beds by night.

These are more common for motorhomes, campervans, and fifth wheels.

Other RVs, mainly the ones with families, have bunk beds

The thing with these beds is, they fit multiple users in a compact space because they come in levels. 

However, they’re mostly only suitable for kids or young teens because they’re narrow.

Special Bed Sizes

Now that we’ve listed all the standard bed sizes from smallest to biggest, let’s take a look at special bed sizes.

These aren’t easy to find on the market; you’ll likely need to custom-make them.

They’re also hard to shop for, regarding linens and accessories.

Olympic Queen

  • Dimensions: 66 x 80 inches
  • Mattress Thickness: 8–20 inches
  • Mattress Weight: 120–180 pounds
  • Price range: $300–$3000

Olympic queen beds are the same length as queen beds, but they’re six inches wider.

They’re the perfect balance between queen and king beds. 

You can choose them if your room fits a bed larger than a queen but not as large as a king.

They offer more sleeping room, so they’re typically the better choice.

The thing is, these beds are a hassle to deal with. Here’s why:

  • It’s hard to find them on the market
  • It’s hard to buy linens for them

Full XL

  • Dimensions: 54 x 80 inches
  • Mattress Thickness: 8–20 inches
  • Mattress Weight: 50–80 pounds
  • Price range: $300–$1000

Full Xl sizes are five inches longer than full ones, with the same width. 

They’re not common on the market because users looking for larger beds typically go for a queen size.

However, full XL beds are ideal for tall users—those who find full beds uncomfortable for their height. 

Seeing as they’re more compact and affordable than queen beds, they’re typically the first choice for these users. 

Full XL beds have the same disadvantages as all special sizes:

  • They’re not readily available on the market
  • Their linens are hard to find
  • They need large rooms

Bed Size Chart

Now that you have all the data you need, here’s a bed size chart to summarize everything I listed above.

Size Dimensions Suitable Room Size Number of Pillows Sleep Comfort Rating
Twin 38 x 75 inches 7 x 9 feet 1 (Plus a small one) 3.5/5 (Single user)
Twin XL 38 x 80 inches 8 x 10 feet 1 (Plus a small one) 4/5 (Single user)
Full 54 x 75 inches 10 x 11 feet 2–3 5/5 (Single user)
Queen  60 x 80 inches 10 x 11 feet 3–4 4/5 (Couple)
King 76 x 80 inches 12 x 11 feet 4–8 5/5 (Couple)
California 72 x 84 inches 12 x 12 feet 4–8 5/5 (Couple)

As you can see, there are endless options when it comes to bed sizes. 

Whether you’re sleeping alone, with a partner, or you only need a bed for your kid, you’ll find an option that suits you on this list.

Beds made for single users are mostly twin, twin XL, and full-size ones. 

Meanwhile, queen beds and larger ones are meant for couples. Some beds even fit a couple and their kid or pet.

As long as you know your needs, your room size, and the bed sizes in order, you should be able to make a choice easily.
