Crib Bed/Mattress

Crib bed has a dimension of 28" x 52" and it is ideal for toddlers or infants. This is the standard dimension across the United States, so it would fit into any standard crib frame you purchase for your young ones.

Twin Bed/Mattress

Twin bed has a dimension of 38" x 75". It is the mattress size suitable for most kids through childhood as it is ideal for a child who has outgrown toddler bed. A twin mattress provides adequate sleeping space for solo sleepers from toddlerhood through the teen years, though an upgrade may be necessitated by adolescents.


Also known as a single mattress, twin mattress is slim in size This mattress is commonly used for bunk beds, daybeds or small guest bedrooms. It can easily be fitted side by side in bedrooms shared by kids.

Though twin bed may seem restrictive for most sleepers, it is the best choice for space optimization. Twin bed may be best for you if you have a small apartment or share a room.

Most twin bed frames are lightweight and highly portable. This makes it easy for you if you enjoy frequent rearranging of your room. Twin bed also provide a luxury feel of a larger mattress without costing much nor taking up much room, which makes it suitable for sleepers on a tight budget.

 

Twin XL Bed/Mattress

Twin XL mattress has a dimension of 38" x 80". It has the same width as the Twin mattress but 5 inches longer in length. The extra length makes the bed accommodate taller sleepers.

Bed frames for Twin XL differ from that of a Twin mattress. Many buyers make the mistake of purchasing a standard Twin mattress frame for a Twin XL mattress and find it hard to fit in their mattress. In the same vein, not all sheets or comforters come in the Twin XL sizes. So, it is important for buyers to double-check the length of bed accessories before purchasing for a Twin XL size mattress.

Two Twin mattresses could also be combined to form a King size mattress. The mattresses could be used with a King size mattress frame or an adjustable frame. Likewise, a King size sheet or individual Twin XL sheets could be used when you opt for two Twin XL mattresses on a King frame. 

Joining two Twin XL mattresses is a nice option for sleeping partners who have different firmness preferences. It also prevents the disturbance of the other partner by the movement of a partner.

 

Full Bed/Mattress

A Full mattress has a dimension of 54" x 75". It serves as a compromise between the Twin mattress and the Queen mattress. The Full bed has the same length as a Twin bed and 16 inches wider. The extra width allows for sleeping companions.

Also known as Standard double or Double bed, the Full mattress is the best fit for single sleepers who wants additional space for spreading out. It is often referred to as the standard bed size, in terms of comfort and economy, for single sleepers. 

For couples with small apartments, the Full bed may be considered suitable. A sleeping space of 27 inches per sleeper is provided which is 11 inches lesser than that of a Twin bed. This may not be conducive for most sleepers.

Full-size bed frames are not as mobile as twin frames but it is inexpensive, lightweight and compact. It is economical and a great investment as it can be moved to the guest room if there is a need to upgrade the bed size.

 

Full XL Bed/Mattress

The Full XL bed has a dimension of 54" x 80". It is sometimes called the Double XL. It has the same width as the standard Full bed, but with extra five inches of length. Just like the Twin XL bed, the extra length gives room to accommodate taller sleepers.

Full XL mattress has the same length as a Queen bed, but narrower by 6 inches. This makes it ideal for tall and active sleepers as it prevents the dangling of feet's off the bed.

Shopping for Full XL bed size frame or sheets requires a double check on the lengths so as not to purchase a shorter frame or sheets that a standard Full sized bed.

 

Queen Bed/Mattress

Queen mattress has a dimension of 60" x 80". The queen mattress is the most popular mattress size in the United States. In the UK, it is referred to as King bed.

The Queen mattress is comfortable for single active sleepers, couples, and those that have a sleeping companion (either children or pets). Due to the extra width and length, queen mattress provides more support and comfortability to couples and taller people that feel a little cramped on the Full bed size.

To accommodate a Queen mattress comfortably in a bedroom, it is recommended that the bedroom must be at least 10' x 10'. Bedding accessories for a Queen sized mattress are widely available at various price points, materials, and styles due to the popularity of the mattress. 

For sleeping partners, the Queen bed will provide a 30" of sleeping space per person which is 8' less than that of a Twin mattress. A Queen mattress is a mattress you cannot outgrow easily, and most master's bedroom can accommodate a Queen mattress easily.

 

King Bed/Mattress

The King bed has a dimension of 76" x 80". It is 16 inches wider than the Queen bed. King mattress is the widest bed on the market and it provides the most luxurious sleeping space. King beds are ideal for master bedrooms that are spacious. A bedroom is recommended to have, at least, a dimension of 12' x 12' for it to comfortably fit a King size mattress.

King mattress is ideal for sleepers who enjoy the luxury of a large mattress. It is extremely comfortable for single active sleepers, has there is enough room to toss and turn. The King mattress is considered the best for couples.

Couples who find the King bed lacking in space or those who share a bed with children or pets would find it comfortable. In cases where one of the sleeping partners is an active sleeper, the other partner need not worry as the tossing of the other partner will not disturb. For exceptional light sleepers, King mattresses are also good as one partner typically can’t feel when another gets into bed or tosses and turns at night.

A sleeping space of 38" per person is provided by the King mattress, just the same as with a Twin mattress. A Split King mattress could be a nice option for sleeping partners who have different sleeping preferences since the mattress allow different feel on each side of the bed. For sleepers who are considering an adjustable frame, the Split King mattress is suitable. The larger size of the King bed makes it difficult for movement.

 

California King Bed

The California King mattress has a dimension of 72" x 84". While it has an extra 4" to the length when compared to the King Size mattress, it is also 4" lesser at the width. Compared to the Queen size mattress, the California King mattress is 12" wider.

California King size is suitable for tall sleepers or sleepers who wants an extra length to the mattress. It is also ideal and extremely spacious for active sleepers or sleepers that have sleeping partners, children or pets.

Your bedroom is recommended to be at least 12' x 12' in order to be able to fit in a California King mattress comfortably. Often considered as the longest bed you can buy, very tall sleepers may want to invest in California King bed so as to prevent dangling of their feet off the bed.

Lovers of large beds may want to consider the California King mattress. The mattress allows for a sleeping space of 36” per sleeping partner for couples, which is 2" lesser than a Twin size mattress.

It is pertinent to note that shopping for a California King bed frame and bed accessories can be a bit tricky. Shoppers should ensure they get the right frame that fits the California King mattress dimension.

How to Compare or Convert Between Bed Standards

Bed standards vary from country to country. America and Europe have a different standard. In the same vein, the UK and Ireland sizes differ from continental European sizes.

It is not difficult to compare European and America bed sizes, however, conversion can be made between the sizes. The American makes use of names such as; Twin, Full, Double, Queen and King for the bed sizes,  UK or Ireland make use of name such as; Single, Double, King, and Super King, while European sizes are often referred to by their width and length in centimetre.(e.g., 90 x 200).

When comparing bed standards, below are steps to be followed.

  1. Determine the dimension of your beds and the system in which they are measured (inches or centimetres).
  2. Locate a conversion chart, which will indicate the width and length of bed sizes either in inches or centimetres.
  3. Convert all the sizes into one measurement system (inches or centimetres) to measure the width and length of a bed
  4. Compare the resulting measurements with the dimensions of your bed. 

For instance, a U.S. Twin bed is 38" x 75" (96.5 x 190.5 cm), which roughly compares with UK/Ireland's single (36" x 75" or 91 x 191 cm).

  

What Bed Size is Right for Me?

One of the important decisions you can make when updating your bedroom is choosing the right mattress size. Many things are to be considered when deciding the right bed size for you.

In order for you to be able to choose the right bed size, we have put a comprehensive guide on factors to consider when choosing the right bed size.

 

Factors to Consider When Choosing Bed Sizes

Choosing the right bed size can have a big impact on your sleep, your health, and your relationships. Therefore, these factors should be put into consideration before sleepers choose bed sizes.

  1. Sleep preference
  2. Your body
  3. Sleep partners or companions
  4. Wallet
  5. Bedroom Dimension
  6. Your home
  7. Your Furniture
  8. Your future

 

  1. Sleep Preference:Are you an active sleeper? Do you toss and turn all through the night? Considering your sleep style or preference is important before you make the decision of buying that mattress. If you toss and turn and would be sharing the bed with a partner, will there be enough room for you to toss and turn without disturbing the sleep partner?
  2. Your Body:Sleepers should consider their height and weight, as well as that of sleeping partners before deciding on the mattress size and frame to go for. Tall sleepers would have to pick a mattress that will prevent dangling off of their feet. A strong bed frame also has to be selected for sleepers that fall into the heavyweight group.
  3. Sleeping Partner or Companion:Before deciding on the mattress size you want to go for, sleepers have to factor in other sleepers. Will you share the mattress with a partner, children or pet?. A mattress with adequate sleeping space for each sleeper should be selected.
  4. Wallet:The price of a mattress has to be considered before you go for that mattress. You don't want to spend extra dollars on sleeping space you won't make use of.  For instance, if you are single, you don't need to spend extra cash on a Queen bed. A Full bed is right, A Twin bed is considered affordable if you don't want to spend that much.
  5. Bedroom Dimension: It is time to get a tape measure and get the dimensions of your bedroom if you don't know it. Knowing your bedroom dimensions would help in picking a mattress size that would fit in comfortably.

Get the length, width and doorframe measurements and decide on the dimension of your potential mattress size. Define the length of the wall the bed will be set against and take into account for clearance needed for doors while also considering the windows.

 

  1. Your Home:Sleepers should put into consideration their homes before making the decision on bed sizes. Will you be able to move the bed through the door? Can you move the bed up the stairs? These are a few questions to answer before picking a bed size.
  2. Your Furniture:If you decide on fixing a reading chair, a bigger dresser as an addition to your bedroom, be sure to identify the space required as well. Add the dimension of the furniture that is available or that you plan to purchase later in future.
  3. Future:Before making the decision on big beds now, take note that beds are hard to move and can easily get damaged. It is advisable to make that big investment in a new bed when you settle in your forever home.

 

Comfort is the most important factor to be considered when choosing bed sizes and dimensions. So, focus on the bed that is going to give you the rest rejuvenation you require.
