If you’re a single sleeper looking for a space-efficient mattress, the first step is to determine which mattress size is right for your needs. The two most common bunk bed-sized mattresses are known Single and Twin. 

But what exactly is the difference between a Single vs Twin bed?

Single and twin mattresses are exactly the same sizes—38 inches by 75 inches. But, notably, a single bed is an individual piece of a mattress, whereas a Twin bed is a pair.

What is the Difference between Single vs Twin Beds?

Single vs Twin beds are the same. However, a single bed is an individual mattress whereas a twin bed is a set of two mattresses. Both the mattresses are of the same size measuring 38 inches wide and 75 inches long.

The term ‘twin’ originated from hotels where they used to place two single beds together in the same room to make a double bed. Twin beds are often supposed to be used in pairs, but they can be used independently. Either way, the dimensions of single and twin beds are the same, and they barely share any difference.

Single vs Twin Bed: Mattress Dimensions

Single bed dimensions are 38″ x 75″, which is the same as twin bed dimensions. However, sometimes twin beds can be 39″ x 75″. So, single vs twin bed size: there is no difference. A single bed or single mattress is the same as a twin bed or twin mattress. However, it is available only as an individual product. You can buy two twins as twin beds or one twin as a single bed. Many hotels use the term “Twin Bed,” two single beds of the same design used in pairs. 

A decade ago, “single bed” or “single mattress” was quite popular. Today, people favor “twin bed” or “twin mattress” even when they talk about only one bed or mattress and not half of a pair.

Single vs Twin Bed: Pros and Cons

What is a Single Bed?

Single beds measure 38 inches wide and 75 inches long. It happens to be the smallest bed size in the market. These beds can accommodate one sleeper easily and have a surface area of 2850 square inches to follow.

Pros

  • Best for small spaces
  • Unlike bigger beds single bed can be used for other purposes
  • Comfortable for small children, teens, and older adults who don’t move too much when asleep

Cons

  • Not useful for kids who have hit the high-school-age
  • Uncomfortable for couples or two people (even slimmest) who want to share the bed 
  • Adults won’t get the best sleep unless they sleep like the dead

What is a Twin Bed?

Like a Single Bed, even Twin beds measure 38 inches wide and 75 inches long. However, if you merge two single aka twin beds together, you can get a bed size close to a king mattress.  

Pros

  • Ideal for kids and toddlers
  • Can move easily
  • Easy to use in bunk beds
  • Less expensive than a full mattress

Cons

  • Kids may grow out of them in a few years
  • Not useful for teenagers and adults
  • Less versatile than a full bed

Factors To Consider While Buying Between a Single vs Twin Bed

Confused about which one to buy? Here are some factors to consider:

Number of Sleeper

For a single sleeper, both single and twin size beds are comfortable. But, buying two twin-size beds is a good idea for two sleepers who want to share the bed. 

Room Size

You can purchase a single bed for a guest room or children’s room, or your hotel room. A twin bed is better for a hostel or kids’ room. If your room size is 10 feet by 10 feet or more, you can buy twin XL or full or queen mattresses. 

Budget

Single vs Twin Bed: Which one is expensive? Well, both are budget-friendly. A larger mattress is costlier than a smaller size mattress. If your room is spacious, but you want to enjoy the space, you may opt for a twin size bed, which is also pocket-friendly. On the other hand, you may opt for a single size bed if available at a lower price than a twin bed. 

Personal Preferences

Twin and single mattresses well suit the needs of a child, teen, or young adult. Will you be more comfortable buying a bed as a single product or two beds with an identical design to make a twin bed? Will you be more comfortable with a twin XL or full mattress instead of a single size bed? The answer to these questions will tell you what is better suited to your needs.

Conclusion

There is hardly any difference between a single and twin bed. Their dimensions are identical, and both types are spacious enough for one child or adult. However, the purpose of both types of beds is slightly different. While a single bed is ideal for kids and toddlers, a twin bed is mainly used for matching pairs in hotels or bed bunks in hostels. In addition, a twin bed is the best fit for siblings sharing the same bed to sleep together or couples who aren’t comfortable sharing the bed but want to sleep together. 

Before buying anyone, please consider your budget, personal preferences, and room size.
