There is a 54-inch by 75-inch difference between a double bed and a large mattress. Double beds and full-sized mattresses are frequently used interchangeably..

The terms “double” and “full,” when used to describe mattress sizes, mean the same thing. Full-sized beds, which are referred to as doubles, can’t comfortably accommodate two adults.

During the 1870s, American furniture manufacturers standardized the dimensions of double beds, and the term “full” was coined. Full mattresses became the normal size for a double bed in the United States whereas twin beds were the standard size for a single bed.

What is a Double Bed?

Before the introduction of queen and king size beds, couples preferred double beds. It’s difficult to get a decent night’s sleep when you’re sharing a double mattress because the surface area is only 27 inches by 75 inches for each person.

Standard twin and full-size mattresses were the most common bedding in the United States in the 1940s. King and queen beds were introduced in the 1950s and quickly became popular. Because the average height and weight of Americans were rising during this time, the demand for larger-sized beds grew as a result.

This boom occurred in the United States following World War II. The vast bedrooms of well-to-do suburbanites necessitated a more substantial mattress. As a result of all these new trends, double-sized beds have fallen out of favor.

What is a Full Size Mattress?

A double bed is the same size as a full mattress. In college dorms, full-sized beds are the norm. Studio apartments and smaller rooms are also suitable places to put them because of their compact size.

A 10-foot-by-10-foot space is ideal for a queen-size bed. Consider the amount of room needed for furniture and strolling around when deciding where to put your bed. On all except one side of the bed, it’s recommended to leave at least 2 to 3 feet of clearance.

Our Amerisleep Full Size Mattresses

It is possible to choose from five different firmness levels for our Amerisleep Mattresses. All of them come in a variety of softnesses, from medium-soft to hard and everything in between.

Bio-Pur®, a plant-based foam, is used in all of our mattresses, making them cooler than memory foam mattresses. To keep you dry and comfortable, we use a material that is both soft and absorbent for our mattress coverings.

Affinity with HIVE® technology makes up the second layer of protection. This layer alleviates aches and pains by relieving pressure on specific areas of the body. It accomplishes this by providing additional head, back, and leg support, as well as shoulder and hip padding. The Bio-Core® layer is found at the bottom of our mattresses, offering both strength and durability.

Our hybrid beds are a great option if you like a more springy mattress. Airflow is enhanced and motion transfer is minimized thanks to a foundation layer of individually wrapped pocketed coils. Each of our hybrids is available in three different levels of firmness.

Double XL and Full XL mattresses are available in both double and full sizes. 5 inches longer than a regular double or full-size mattress, these mattresses are 54 inches wide by 80 inches long. A few more inches are useful for those who sleep on their sides.

Variations of the Full Size Mattress

This size is rarely found in mattress stores or on the internet. When looking for a full-size mattress, we recommend doing some research on the brands that carry them before going to a store or shopping online. These sizes are so uncommon that it may be difficult to obtain bedding that is appropriate.

Other Standard Sizes

While twin and twin XL beds are broader than a full, queen, and California king beds, a double or full size bed is narrower. Other common mattress sizes are available if a double or full size does not meet your needs.

Twin Size Mattress

The dimensions of a twin mattress are 38 inches wide by 75 inches long. Small in stature, this is an excellent choice for children’s bedroom. Even though single adults can use a twin mattress, there isn’t much room for limbering up and unwinding on it. To make the most of a limited amount of room, twin beds make excellent bunk beds.

Twin XL Size Mattress

Mattresses in the Twin XL size are 5 inches longer than those in the standard twin size. For teenagers who are still growing, the extra length is a boon. Twin XL mattresses, which measure 38 inches by 80 inches, are typically found in children’s rooms and even in adult bedrooms where two people share a space. When compared to a full-size mattress, the twin XL’s dimensions are 5 inches longer and 16 inches narrower.

Queen Size Mattress

The dimensions of a queen-sized mattress are 60 inches wide by 80 inches long. Compared to full-size beds, queen mattresses are 6 inches wider and 5 inches longer. Because they may be used by a single person as well as a couple, queen-sized mattresses are the most popular of all mattress sizes. Your guest room or master bedroom can each have a queen-sized bed. Restless sleepers benefit greatly from the extra space.

King Size Mattress

In terms of normal size mattresses, a king-sized mattress is the most expansive. For couples that need extra room to sleep, king-sized beds are an excellent option. The king-sized bed has ample room for children to join their parents for a few nights at a time. Compared to a full-size bed, a king’s mattress is broader and taller by 5 inches.

California King Size Mattress

Standard-size California king mattresses are among the longest in existence. For tall people, cal king beds come in 72 by 84 inches. When it comes to large master suites, Cal king beds fit the bill. This mattress is 18 inches wider and 9 inches longer than a typical full-sized mattress.

Full vs Double Mattress: What’s the Difference?

You may be wondering why there are two different names for 54″ by 75″ mattresses.

When it comes to a full vs. double bed, there really isn’t any other distinction to be made.

Twin-sized and Full-Sized originate from the dimensions of this mattress in respect to a full-sized bed. There are two names for the same mattress size: a queen and a king.

  • Shortly after the Civil War, mattress manufacturers began standardizing their sizes. A “single” (what we now refer to as a twin) and a “double” were the only two mattress sizes available in the late nineteenth century.
  • This mattress is only 16 inches wider than a 38 by 75-inch twin mattress, despite its name suggesting it is twice as large as a twin.
  • Mattresses referred to as “full” or “double” are so termed because they can accommodate two persons instead of just one.

Up to the 1950s, couples slept in regular double or full beds. As the population grew taller, manufacturers began to lengthen the traditional king and queen bed proportions.

Those who are taller than 6’4″ may find a full-sized bed uncomfortably close to their shoulders.

FAQs

Can a double bed accommodate two people?

What size mattresses are most comfortable for couples?

If you have two adults who sleep together, you should opt for a king-sized bed rather than a queen. In comparison to a queen, the king size bed provides 38 inches by 80 inches (the size of a twin XL) of area for each sleeper. A queen-sized mattress is an excellent choice if your space is too tiny for a full-sized bed.

Can you easily find bedding accessories for full size mattresses?

You may readily get bed frames and bedding accessories for full size beds in mattress stores or on the internet, because full or double size mattresses are the common mattress sizes. Bed frames and bedding items for full XL sizes are a little more difficult to come by.

Is a double bed the same as a queen?

Queen-sized beds are wider and taller than double-sized beds by 5 and 6 inches, respectively. For couples, a double (or full) bed was the norm until the arrival of the queen size mattress. Until recently, double beds were mainly used by couples.

What is a full double bed size?

It is 54 inches broad by 75 inches long, or 137 by 190.5 cm, to be precise.

Conclusion

The dimensions of a double or full-size mattress are the same. You’re not sure what size you need? You’re not the only one. Even if you’re familiar with mattress sizing concepts, the variety of bed sizes might be difficult to navigate when shopping for a new mattress. Knowing the dimensions of a standard-sized bed’s mattress can assist you in making the best decision for your specific needs.
