What is a Twin Size Mattress?

Twin mattresses, sometimes called single mattresses, are the smallest mattresses available in the market (excluding the crib mattress). They are 75 inches in length and 38 inches in width and are suitable for a single person, child, or teen. People generally buy them for children’s bedrooms.

Pros

  • Cheapest mattress for children’s room after crib mattress
  • Great for kids, toddlers, growing teenagers
  • Ideal for bunk beds, kids room, and hostels

Cons

  • Not suitable for tall teens and adults
  • Cannot accommodate couples

What is a Full Size Mattress?

Full size mattresses, also popularly known as double bed mattresses, are 74 inches long and 54 inches wide. Full mattresses are perfect for a single person with average height and adults who want extra space while sleeping. 

Couples who like to cuddle while sleeping can also choose a full-size mattress. However, queen size mattresses are more popular among couples as they offer more personal space. 

Pros

  • Perfect for taller teenagers and adults who like to sleep alone
  • Best-suited for guest rooms, dorm rooms, and smaller apartments
  • Accommodates more accessories compared to twin beds

Cons

  • Too small for couples who need personal
  • Takes more room space compared to a twin
  • Costlier than a twin mattress

Things to Consider Before Deciding Between Full Size vs Twin Size Mattress

 Room Size

Both twin and full bed mattresses can adjust in most rooms. Twin mattresses, which are 38 inches by 75 inches, are smaller and can fit perfectly in a room that is at least 9 by 9.6 feet. Twin mattresses are best-suited for kids’ rooms, hostels and can also be used by adults in studio apartments.

A full size mattress fits in a room that is at least 10 by 10 feet but is better suited for a room that is 10 by 12 feet. Using a full size mattress in a bigger room gives you the extra space to furnish your room. Full size mattresses are commonly bought for college dorm rooms, apartments, and small master bedrooms. 

Accessorise 

Accessories for twin mattresses are cheaper compared to full mattresses since they are smaller in size. While a twin mattress can fit only one pillow, a full mattress can fit in two pillows allowing more space to accessorize the bed. Twin size bedding such as duvets, covers, waterproof covers, and throw pillows is also cheaper than bedding for a full-sized mattress as they are different dimensions.

Budget


Full size mattresses are costlier than twin mattresses as they are bigger. The price difference between a twin vs full bed is anywhere between $200 or more, depending on the brand you choose.  The Dream cloud full size mattress costs about $899, and a twin mattress costs $699. Other factors that affect pricing are brand, quality, and type of material used in manufacturing the mattress. 

Bed Size

A full size mattress fits perfectly on a full or double bed which is 54 inches wide and 75 inches long. If your bed is anything smaller than a full bed then it will cause the mattress to hang from the sides and cause discomfort while sleeping.

 A twin mattress can fit in the children’s room on a bed that is at least 38 inches wide and 75 inches long. A standard bunk bed or a loft bed for children measures 39 by 75 inches, making a twin mattress ideal for these beds. 

Height

Full-size mattresses are broader than twin size mattresses which allows more sleeping area for taller individuals. However, twin and full mattresses are both 75 inches or 6.2 feet long, so it doesn’t provide enough room to stretch the legs out for individuals taller than 6 feet 2 inches. Check out other sizes such as queen or king size mattresses for such cases. 

Choosing Between Full vs Twin

A standard twin size mattress at 38 inches wide can only accommodate one person comfortably. Because of its compact size, it’s perfect for children transitioning from a crib mattress. It can also fit an adult but is better suited for teens and children due to the limited sleeping space.  

A standard full size mattress, the size right after twin size mattresses, is a great option for a single adult or a single adult with a child or a pet. 

Between full bed vs twin, a twin is better suited for a teen while a full mattress is for an adult. We hope this guide helps you choose the right bed for you. 

What is the difference between a twin and a full mattress?

Twin and full mattresses are equal in length. However, a mattress for a full size bed is 16 inches wider than a twin mattress. The former is more suitable for children and growing teenagers, whereas the latter is perfect for taller teenagers and young adults sleeping alone.

Is a full mattress enough for couples?

Couples who like to cuddle while sleeping or have a limited budget can purchase a full mattress. Yet, a queen size mattress at 60 x 80 is ideal for two adults who share the bed because it is wider and a few inches longer than a full bed.

Is a twin mattress too small for an adult?

A twin mattress is too small for couples and people of height more than 5’5 feet. You can look at a twin XL mattress if you are an adult who likes compact sleeping spaces. It is also small if you are considering it for your master or primary bedroom. However, it is the perfect size for kids transitioning from a crib to a bigger bed.
