A Closer Look at The Different Mattress Sizes

Now that we have the basics covered, let us dig deeper about the different mattress sizes available in the market:

  • Crib

This mattress size is perfect for your baby’s first bed. If you are worried that the mattress might not fit the crib that you have bought, there’s nothing that you should worry. The dimensions depicted in the table are considered to be standard across the US, so it will fit the standard size of cribs (unless of course, the size of your crib is not standard).

What you would notice about crib mattresses is that they are firmer than most adult mattresses to prevent SIDS (Sudden Infant Death Syndrome). When looking for a crib mattress, you may also want to go for a lightweight one so you can easily remove it from the crib in case of spills.

  • Small Single

Not all US mattress brands offer this size because it is a UK standard bed size, but this is worth mentioning in this guide simply because it is the mattress size of choice for taller toddlers and bigger babies.

This is also the bed size of choice of parents who are trying to save space in a small room or for toddlers who are now ready to transition from a crib to a cot bed.

  • Twin

Also known as the single mattress size, it is the most common size of the mattress being used by toddlers during their entire childhood. In fact, they may even use this up to their teenage years, except of course, when growth spurts take place.

The mattress’ slim size makes it easy for the users to fit two mattresses side-by-side for a shared kid’s bedroom. This is also the go-to size for bunk beds.

Since this is the next bed size for toddlers, it is recommended that you attach safety rails on the side of this mattress to prevent your child from falling or rolling off the bed.

If you have a smaller guest bedroom, this is the perfect size for a day bed. You can also easily incorporate this bed size in odd-shaped bedrooms or spaces.

If you want to accommodate more than one kid in a bed but you do not want to shell out money for a queen or full-size mattress, your next best option is to buy foam bridge pads so you can attach two Twin beds together. The resulting size is suitable for two kids but is not recommended for an adult because its length won’t be enough.

  • Twin XL

This is also known as Single XL and has the same width as that of the Twin size but is considered to be 5 inches longer, so it has the same length as that of Queen or Full mattresses.

Because of its length, this mattress is perfect for adults who are trying to save space in a narrow room. That is why you would most commonly see this mattress size being used in college dorm rooms.

If your kid’s room is large, you may want to invest in this mattress size instead of the Twin as your child can be able to use it even during his growing years.

  • Full

You may also hear some people call this mattress size double bed but don’t be confused. This mattress size has the same length of Twin but does not have twice the width of a Single mattress.

A Full size mattress is not recommended for accommodating two people. Instead, it is the best size for single adults who want to enjoy extra width and has lots of space to spare in his room.

If you usually sleep with your child or a pet, you can truly benefit from the extra width that this size offers.

Young graduates would also appreciate both the mattress’ affordability and size.

So once again, you should remember the Full or double size is not for two people—but for a single adult with a pet or child and have lots of space and a bit of money to spare.

  • Queen

According to statistics, this is the most common mattress size in the US right now. That is totally understandable given the fact that this mattress provides couples enough space to move around, but at the same time, it still fits a standard sized master’s bedroom.

If you and your partner love to sleep close together, there is no doubt that this is the mattress size for you. But with its price point, this mattress can be quite versatile. It is also perfect for adults who want to enjoy the luxury of space or for people who sleep with two kids or a large pet.

Since the queen size is the most popular mattress size of all, you can enjoy the advantage of choosing from a wide array of choices—from the materials, styles, and price points. You are also provided with an excellent opportunity to choose from a diverse range of beddings and accessories.

  • Olympic Queen

Six inches wider than the Queen, this mattress offers a size that goes in between the size of the King and the Queen. Because of this, it is the perfect option for couples who still want to enjoy their individual spaces when they sleep but do not have space or money to buy a King size mattress.

However, this mattress size is not as common as the queen size. Because of this, you may experience some difficulties in choosing bedding accessories and covers for this mattress.

  • King

This mattress size is called King mainly because people believe that it is fit for a king and that does not come as a surprise considering that it gives you the width of two Twins, perfect for a couple who likes to stretch it out. It is also a good choice for couples who usually sleep with a small kid or pet.

However, there are three things that you need first to consider before you invest in a King size mattress—budget, room size, and the moving and assembly process.

Since it offers the luxury of space, you can expect this mattress to be a bit expensive, so it may not be suitable for people with a tight budget.

Because of its dimensions, King mattress size may be a bit too big for standard sizes of Master’s bedrooms. That is why it is vital that you measure your bedroom first before making a decision.

Lastly, the King mattress size may not also fit in the stairs. It is also heavier than the Queen mattress and may require more people to carry it up the stairs. To make the assembly and moving process as easy as possible, it would be best that you buy from a company which offers delivery services. You may also want to look for mattresses that can be easily folded or rolled so you can easily carry it up the stairs.

  • California King

One thing you should understand about this mattress size is that it is the longest mattress of all, but it is not the widest (that is the King mattress size). This mattress is designed not to offer a luxury of space to the user. It is engineered to accommodate the height of taller sleepers.

If your feet have always hung off the edge of your mattress when you sleep, this mattress size can help solve your problem. While it is considered to be narrower than the King mattress size, it can still offer you more space than the Queen size.

This is also the go-to mattress size for rooms that are longer than they are wide. The difference in its width makes the California King a perfect fit for most regular rooms which are not able to accommodate the width of a King mattress size.

If you are confused as to which mattress size you should choose—King or California King, it is advised that you consider your bedroom size, the size, and placement of your bedroom furniture and the way that you want to maneuver the mattress.

A Guide on Choosing You Mattress Size

Now that you know all the critical information about the different mattress sizes available in the market, you may already think that you are ready to buy a mattress. But wait, you may wish to consider these few factors before you make the decision:

  • Number of Sleepers

Before purchasing a mattress, you need to determine if you will be sleeping on the bed alone or with a partner. In addition to that, you also need to know the size and length of the other person who will sleep on the bed.

For single sleepers, the suitable mattress sizes are Twin, Twin XL, and Full. For two sleepers, the most recommend mattress sizes are Queen, King, and California King.

In general, Twin and Twin XL are less wider than Full mattresses. If you do not need too much space, Twin and Twin XL sizes will do while the Full sized mattress is recommended for people who toss and turn around at night.

For couples who do not mind sleeping too close together, the Queen size would suffice. But if you prefer to have more space, California King or King sizes are recommended.

  • Body Type

If you have standard height or weight, any mattress size will do. But for people with larger bodies, you need to consider the width of the mattress. The best options that you have are either a Queen or Twin.

If you are taller than most people, then you need to factor in the length of the mattress. For people who are less than 6 feet, twin or full mattress is recommended. If you are 6 feet and 7 inches tall, the best mattress size for you would be either Queen or King. On the other hand, the California King Size is perfect for people who are 6 feet and 11 inches (or less) tall.

  • Children and Pets

Aside from your partner, are there other people or pets who would be sharing the bed with you? If you are sleeping with one small child, go for Queen or Twin size. If there were an older child or two small children with you in the bed, it would be wiser if you will invest in a Full size mattress.

If you share the bed with one adult and another children or pet, you may need to shell out money for the King or California King size mattress.

  • Sleeping Position

How do you sleep at night? You have to make sure that the mattress size that you will choose can accommodate all the movements that you will make throughout the night.

If you are a single person who sleeps on your stomach or back, the best sizes would be Twin XL. If you sleep on your side, the Twin size would be enough for you. But if you are a combination sleeper (you toss and turn at night), Full size mattress is most recommended.

If you are sharing the bed with another person, you have to take into consideration their sleeping positions too. If anyone of you is a combination sleeper, go for the broadest mattress size available.

  • Bedroom Space

A mattress, regardless of its size, will take up significant space in your room. Because of this, it is essential to make sure that the mattress you will buy will not make your room feel crowded. To ensure that, here is a simple guideline on square footage measurements for different mattress sizes:

– Twin Mattress is recommended for a room measuring 2,925 sq. inch or 20.3 sq. ft.

– Twin XL Mattress is recommended for a room measuring 3,120 sq. inch or 21.7 sq. ft.

– Full Mattress is recommended for a room measuring 4,050 sq. inch or 28.1 sq. ft.

– Queen Mattress is recommended for a room measuring 4,800 sq. inch or 33.3 sq. ft.

– King Mattress is recommended for a room measuring 6,080 sq. inch or 42.2 sq. ft.

– California King Mattress is recommended for a room measuring 6,048 sq. inch or 42 sq. ft.

In addition to the mattress size, you need to consider the mattress and bed height as well. If you have a low ceiling or lighting fixtures, avoid beds that are too high.

  • Age

If you are looking for a child’s mattress, this is one important thing to consider. If your child is 18 months old or younger, the crib or cot size is recommended. But if he is already older than 18 months or taller than his age, the Small single (or Toddler) size is more suitable.

  • Budget

Prices of mattress may vary depending on its size. The broader or bigger the bed is, the more expensive it is. But in addition to that simple fact, you should also remember that the price-points of each size may also vary depending on the brand. Because of this, you should make it a point to compare the price of the different sizes and brands of mattresses.

More Mattress Buying Tips You Need to Know

We are now done with the theoretical part of finding the right mattress size; it is about time that we discover its practical side. With that in mind, here are other mattress size tips that you should know about:

  • Get the actual dimensions of the bedroom.

For this activity, you would need a tape measure. You will use this to measure the width and length of your room. As you do this, it is also best that you define the length of the wall where you plan to set your bed against. In this way, you can determine the needed dimensions for the potential bed space.

When choosing an area where you can prop your bed against, you have to make sure that you won’t be blocking any windows, built-in fixtures, and doorframes. You should also take into consideration the clearance required for your door (if it swings into your room).

For a more detailed guide, please watch this video:

  • Imagine how different bed sizes will look in your room.

The mattress size chart we have provided already gives you the exact dimensions of each mattress size. You can use these dimensions to imagine how much space the bed will take up.

Following these dimensions, block off that space in the intended bed space inside the room. You can do this by tracing the bed using painter’s tape. If you do not have one, you can simply mark the corners of the imaginary bed using four water bottles.

If you have not decided which mattress size to use yet, you can try incorporating your three options into your room.

  • Consider the size and placement of the furniture that you will purchase (or have already bought).

Get the dimensions of these fixtures and plot its placement in your empty room using painter’s tape.

  • Imagine how you will move around the bedroom.

Considering these dimensions and placement, try to imagine how it will be like when you go through the motions of your daily life (get ready for the day, open your closet, sit on your dresser, read or stretch). You may also like to walk around the remaining space in your room.

After doing that, evaluate the entire bedroom space and ask yourself the following questions:

– Does the area feel cramped?

– Did you think that the bed consumed too much space inside the room?

– Do you still have enough space to walk comfortably around the room?

– Is there enough space for your nightstand and dressers to open?

– Do all doors(bedroom door, door to closet or bathroom) in your bedroom open freely?

– Can you open or clean your windows without any blockage?

– Is any of your bedroom furniture blocking your heat and air conditioning systems?

Answering these questions will help you decide which mattress size suits your room size the best.

To have a happy and healthy marriage, your sleeping experience should be enjoyable and comfortable. Now, this does not mean that you should sleep on the widest and biggest mattress available. Instead, you need to think of the way you and your partner sleep.

If you and your partner enjoy sleeping close with each other, a smaller mattress is recommended but if you wish to have enough space to move around, go for the larger mattress.

Sad to say, California King size is already the largest and widest mattress size available in the market. If this mattress size is still not suitable for you, you have no other choice but to have a mattress customized for your size.
