Single vs Twin vs Full Bed
A single bed

A single bed is usually 39 inches wide and 75 inches long. It is intended for only one person to sleep in and it goes best in a child’s room or in a small guest room. Single beds can also be placed next to a big bed in hotel triple rooms. These are usually the types of beds bunked together to save space in  children’s rooms or in units where more people need to sleep in the same place.

A twin bed is 39 inches wide and 75 inches long. This is supposed to be one of a matching pair of single beds. They are good for a children’s room shared by siblings and for hotel rooms or guest rooms. A room with twin beds is usually the choice of people sharing a room who do not form a couple or simply do not feel comfortable sleeping with another person. Sometimes there can be extra long twin beds for taller people which are 80 inches long.

A full bed is at least 54 inches wide and 75 inches long. This is usually a bed intended for two people to sleep in. In hotels, this is usually referred to as the matrimonial bed. However, its width makes it preferable for people who sleep alone but who like to have some more room to roll around in.

There are other types of full beds, the standard being the smallest one. There is the Queen bed, which is 60 inches wide and 80 inches long, the King bed which is 76 inches wide and 80 inches long and the California king bed which is 72 inches wide and 84 inches long.

Single Bed vs Twin Bed vs Full Bed

So what is the difference between single bed, twin bed and full bed?

It seems that the single bed has the standard measurements. This is the bed designed for one person to sleep in alone, comfortably. The twin bed is the same as the single bed, although this one is supposed to be part of a set. When buying beds for a guest room or for the children’s room, people usually buy two alike, hence the name of the twin bed. Even so, due to the fact that the twin bed has the same measurements at the single bed, people use their names interchangeably.

Hotels will use both twin as well as full beds in their rooms and accommodate people who want to sleep in the same bed in the full beds and people who want to sleep separately in twin beds. Some hotels can even buy only twin beds and place them one next to another to make a full bed.

A full bed’s width is 54 inches, meaning that a person has only 27 inches to sleep on, when the bed is shared. By comparison, a single bed or a twin bed is 39 inches wide, being more comfortable for one person to sleep in. The people who want more room can either choose to sleep alone in a full bed or to go for the wider and longer versions of the full bed, the queen and king beds.
