What is a full size mattress?

Mattresses come in a variety of different sizes and whilst you may be familiar with a twin, queen or king, the full size mattress is right in the middle of that size spectrum. 

A full size mattress is larger than a twin but smaller than a queen, making it perfect for singles who want a bit more space or couples who want to save space within their bedroom. A full size mattress is also known as a double mattress and measures 75 inches long and 54 inches wide (for those who like to work in centimetres that’s 191cm long and 137cm wide). 

It’s worth noting that not all mattress brands make beds in a full size and instead jump straight from twin to queen. If you’re unsure what bed size is best for you, take a look at out twin vs full size mattress buying guide and our full vs queen size mattress buying guide.
