Americans want more room in bed. Increasingly, shoppers are looking for bigger bed sizes for their homes: A 2020 study showed that millennial shoppers prefered larger mattresses.
Manufacturers are listening, and slowly, bigger mattress sizes have started to join the market. A California king is well-known, but what about a family king or an Alaskan king? There are mattress sizes larger than a king mattress, and it helps to know what they are before you begin shopping.
If you have the room, these are your options for an oversized mattress.
There are several bed sizes available beyond the standard king, including custom sizes for more unique spaces.

California King
Measurements: 72″ x 84″
A California king is not quite as wide as a standard king bed, falling 4 inches short, but it is 4 inches longer. It is designed for taller people, especially if you are a stomach sleeper or back sleeper. Because it is more narrow than a standard king, it can be a good fit for more narrow rooms in your home. California king mattresses generally range in price from $950 to $2,000, on average.
Also known as a grand king, a Texas king is larger than a California king. It is both wider and longer, best accommodated by larger rooms measuring 12 by 14 feet or more. Because it is rectangular, it is best suited for rooms that are a little more narrow than most. Couples sleeping with a child or pet will find that a Texas king gives much more room to move around. For a Texas king, be prepared to spend between $2,000 and $4,000, on average.
Wyoming king
Measurements: 84″ x 84″
A Wyoming king is a square mattress that is as long as a California king but much wider. It is the smallest square mattress, but it is big enough to fit two adults and a child or pet comfortably. Because of its square shape, it could work for most master bedrooms and is one of the more affordable oversized mattresses, with average prices falling between $1,500 and $4,000.
