Beds have been used for centuries for sleeping purposes. The ancient Greeks and Romans also had their own versions of beds, which were often constructed of bronze or precious metals.

During the Industrial Revolution, beds were made in a significantly different manner. As a result of the introduction of mass production techniques, beds became more affordable and accessible to the general public.

The evolution of single beds continued in the early 20th century. New materials, such as steel and plastic, improved the affordability and practicality of single beds. In addition, box springs revolutionized the way beds were manufactured, providing more comfortable and supportive sleeping surfaces.

5. Modern-Day Single Beds

The single bed now comes in a variety of styles and materials, ranging from traditional wooden frames to modern metal and plastic frames. Single beds remain a popular choice for children’s rooms, guest rooms, and small spaces, as well as for individuals with limited space in their homes or who prefer to sleep alone.

Single beds have evolved and changed with the times, reflecting the needs and preferences of each period, from their earliest beginnings in ancient times to the modern-day designs we know and love today.

What size are single beds?

It is important to consider the size of your bed when buying a new one. In this article, we will examine the standard size of single beds and some variations you may encounter. Single beds are a popular choice for many people, but what size are they?

1. Standard Size of Single Beds

There is typically a 39-inch width by 75-inch length standard single bed in the United States. This size is the same size as a twin bed, which is often interchangeable with a single bed. The size is suitable for children, teenagers, and adults who are shorter than six feet tall.

Compared to their American counterparts, single beds in the United Kingdom are slightly smaller. They are typically 36 inches wide by 75 inches long.

2. Variations of Single Beds

Although a single bed is typically 39 inches wide by 75 inches long in the United States, there may be variations in size. For example, some manufacturers make narrow single beds that are only 30 inches wide. These beds may not be comfortable for adults but are great for children or small spaces.

An extra-long single bed measures 80 inches long instead of 75 inches, making it an ideal choice for taller individuals who find standard single beds too short.

You may also find other types of single beds, such as trundle beds, bunk beds, and daybeds. Each of these beds may have slightly different dimensions based on its design, so please make sure you check the measurements before purchasing.

The small single bed measures 2 feet 6 inches by 6 feet 3 inches (75 cm by 190 cm) and is suitable for children under ten. For taller adults or those who require additional space, the large single bed is 4 ft x 6 ft 3 in (120 cm x 190 cm). It is ideal for taller adults or those who require more space, as it measures 4ft 6in x 6ft 6in (135cm x 200cm).

How to choose the right size single bed?

Choosing the right size single bed for your child requires several factors.

The first consideration should be the size of the room. If the bed is too big or too small, the room will appear cramped and out of place. 


Second, consider the age and height of your child. They will have difficulty getting into and out of a bed that is too large or too small for them. 


As a final consideration, take into account your child’s sleeping habits. Individuals who move around a lot in their sleep may benefit from a smaller bed.


1. What is a single bed size in CM?

It is common for individuals who are considering buying a single bed to be concerned about the dimensions of the bed and mattress. A single bed and mattress typically measure 90cm in width and 190cm in length, which is approximately 3 ft in width and 6 ft 3 inches in length. 

When choosing a single bed, it is important to keep in mind the size of the room and the comfort requirements of the user. Single beds are commonly found in small bedrooms and guest rooms.

2. What is the difference between a small single bed and a single bed?

In selecting a bed, size plays an important role. A small single bed is a narrower version of a standard single bed, measuring 2 feet 6 inches wide by 191 cm long. In comparison, one single bed measures 3 feet wide and 6 feet 3 inches long by 190 cm wide. 

Small single beds are the same length as single beds, but they are 6 inches narrower, so they’re a popular choice for people with smaller rooms. In addition, it is a good option for toddlers who are transitioning from cot beds but are not yet ready for full-size single beds. When choosing the right bed size, it is important to take into account the comfort needs and sleeping habits of the user.

3. What size bed is 160x200cm?

A 160x200cm bed has dimensions of 160x200cm, which makes it slightly longer and narrower than a standard king-size bed in the UK. This bed is also known as a Euro-King bed. This size is popular across Europe, and it has become so popular that many UK retailers have added it to their standard-size options. 

There is enough width and length for two persons to be comfortably accommodated by a Euro-King bed. It is, however, important to note that bed sizes can vary from region to region, so it is always a good idea to double-check the dimensions before purchasing.

4. Why single beds are better?

There are many reasons why single beds are popular choices. In addition to their convenient dimensions, they’re also an affordable option for children’s bedrooms, making them a great choice for parents on a budget. 

Single beds are usually designed for children younger than six years of age, but larger versions, such as twin-sized beds or futon beds, are often found for older children and teenagers. For those seeking a practical and cost-effective sleeping solution, single beds can be a great investment.


The size of a single bed for a child is a pervasive question. There are two reasons why this is important. In the first instance, many parents prefer to avoid adjusting a double bed to be suitable for a single individual. In addition, some children are so excited about the new bed that they want to try it out as soon as possible.
