This article is all about king mattresses. If you’re here wanting to know how wide is a king size bed, you can find that answer below, along with plenty of other information from king size bed dimensions to the best rooms suited for these large, luxury beds.

King Bed Dimensions: What are Standard King Size Mattress Dimensions?

There are two king bed sizes. There is the standard king, sometimes referred to as the eastern king, and then there is the longer, California king. The standard king is the same length as a queen size bed, but it’s much wider. The specifics are 76 inches wide by 80 inches long. While the length remains the same, the king is 16 inches wider than your standard queen mattress.

If you upgrade and get the California King, you will add some inches in length and lose some in width. The California king bed dimensions are 72 inches wide by 84 inches long. Both are large enough for a couple. It just depends on how long or wide you’d like your bed to be.

King Bed Size: Who is a King Bed Made for?

Just about anyone will fit in a king size bed. Due to its size, it’s best for couples. You wouldn’t buy a king size bed for your children and it’s highly unlikely that you’ll see a king size bed in most guest rooms. Overall, a king size bed is usually found, and is most well suited, in master bedrooms.

What Rooms Work Best for King Size Mattress Dimensions

If you have the space, you really could put a king size bed in any bedroom you wanted. However, due to the more expensive cost, and the overall size of a king bed, you’re most likely going to find it in a master bedroom. Generally, guest rooms and second or third bedrooms are smaller and less likely to accommodate a king size bed. Additionally, as queen size beds are close in size, but usually cheaper, it often makes sense to have them in guest bedrooms.
