Almost all mattress manufacturers have six main standard sizes of mattresses. In descending order of size, they are king, cal king (California king), queen, full, twin XL, and twin. Split king is another size option, just two twin XL beds paired together. The size of the mattress you need depends on many factors. You must consider available space, ease of movement throughout the home, the number of people sleeping on the bed, the size of the people sleeping on the bed, and many more. It’s also important to know that the thickness of each mattress varies from model to model. Generally, they range from 6″ tall up to 22″ tall.
