How big is a king size bed?

A king size bed in the US is 76" wide and 80" long (approximately 193cm wide and 203cm long), which is the size of two twin XL beds pushed together. They tend to suit bed-sharing couples and co-sleeping families, along with spacious bedrooms. 

They are much larger than twin, full, and queen beds, and are wider but shorter than California King beds. However, a standard king mattress and Cal King mattress are usually priced the same.
