How big is a single bed?
A single bed is 39 inches wide and 75 inches long. Its main purpose is to accommodate one person. Obviously, this is where the name "single bed" comes from. These beds are comfortable and convenient for a child's room and will likely fit the child until he enters high school age, as 75 inches may not be enough at that time. It is one of the most popular choices when it comes to furnishing a child's room.
How big is a double bed?
A twin bed is practically the same size as a single bed. However, it is intended to be one of a pair of single beds. They are often placed in guest rooms that are shared by more than one person. They are also commonly chosen by couples who prefer to sleep together but do not want to share a bed because they find it uncomfortable.
It is also important to note that twin beds come in several different variations in size, with the most popular being the double queen.
Twin X
There is only one difference between a regular twin bed and an XL twin bed. The latter has an additional 5 inches in length and is suitable for college students and those who are slightly taller.

Who should have a single bed?
Single beds are usually placed in a child's room. They're also pretty perfect for hotel rooms that are designed to sleep three people. These are so-called "triple rooms" and are very distinctive for low-cost hotels and motels because they are more affordable, but also do not compromise your sleeping comfort.
Also, if you have a smaller guest room and can't afford to place a larger size unit, then a single mattress is preferred.
Who should have a twin bed?
As we have already explained above, twin beds are designed to be used in pairs. Their most common application is a regular double room in a hotel. Many hotels use it instead of a regular king size bed or a regular twin bed to accommodate the multiple needs of both single and couple clients.
Also, as we mentioned above, for rooms shared by siblings, for example, twin mattresses are preferred.
Conclusion
There is obviously no difference in size between a single bed and a double bed, but the intent and purpose of these two beds are completely different. This is something you have to consider when making your decision. Take the above into consideration to make sure that everything is handled perfectly.
