The History Behind Mattress Sizes

Mattress sizes used to be inconsistent and confusing until the late 1800s. They would come in different builds and were not standardized, making it harder for the consumers to know what size mattress they needed or wanted. This is where manufacturers came in and tried redefining the dynamics of the mattress industry.

Here is a brief history of original mattress sizes and what they looked like.

The late 1800s were a simpler time. The two most prominent mattress sizes in the market were the infamous:

  • Double or Full Mattresses (measuring 54 inches wide and 75 inches long)

  • Single Mattresses (measuring 38 inches wide and 75 inches long) 

So it was simple back then – single mattresses (today’s twins) were meant for one person who could sleep comfortably by themselves, while double or full size beds took up two people together as they are today.

Modern Mattress Sizes

People were significantly smaller before the mid-20th century, so modern mattress measures were needed to keep up with the growing support needs. And that’s how the king and queen mattresses were invented to meet the markets’ demands.

Mattresses that offered extra sleeping spaces for a family of 3 and more to accommodate a single bed instantly became a rage amongst people. This substantially replaced full size mattresses. But, a full size mattress, even to date, remains an infamous choice for couples who like to sleep cozy and closer to their partners or for single adults who desire more space in their beds. 

Given the popularity of all bed sizes, the queen size undoubtedly remains the most sought-after choice for couples with king and full mattresses withstanding as runner-ups.
