King-size Bed Breakdown: Eastern vs. Western Size

The Ensemble Bed has moveable backrests and side tables with a low leather upholstered frame that could serves as additional seating and allows you to move around the bed even if it was against the wall.


It’s likely you’ve heard a King-size bed called one of four names:

  • Eastern King or Standard King (76″ wide x 80″ long)
  • California King or Western King (72″ wide x 84″ long)

The Standard King and Eastern King are interchangeable and refer to the most typical King-sized bed. The other type of King is the California King or the Western King. These two main types of bed sizes can be really confusing but there aren’t whole lot of differences between them.

The Standard/Eastern King is the most commonly purchased King-sized bed. This bed is basically the size of two Twin-sized beds pushed together. This bed is usually 76 inches wide and 80 inches long. The biggest difference between a Standard/Eastern King and a Western/California King is the narrowness and length. The California King is made specifically longer to accommodate taller people. Although the fact it’s longer is a great option for those over six feet, the design of the bed is lacking in width and is narrower than the Standard King.

The Western/California King is the less popular of the two but is commonly purchased for taller individuals. This bed usually measures at 72 inches wide and 84 inches long. The perks of this size of king is the extra 4 inches added to the bottom but the drawback is the 4 inches taken from the sides that the standard size offers.

Room Size for a Standard King

Based off of the most commonly purchased king, the Standard King, the minimum room size according to is 12 feet by 9 feet 10 inches. Most designers will tell you that you need a minimum of 30 inches all around the bed for movement. Although this is only a suggestion, you can use this measurement as a rule of thumb when determining if your bedroom can accommodate a King-sized bed.

When beginning to shop for a King-sized bed, you’re going to want to take in consideration the size of the bed around the mattress as well as the mattress size. You may be purchasing a platform bed that hugs the mattress and is the size expected. You may also purchase a bed that adds a lot at the end of the bed, such as drawers and storage, which will make it larger than expected.

There isn’t a specific standard size for a room but a minimum size suggestion because all rooms differ so greatly. Even if you compare a room to another room that is identical in size, you may have differently placed windows, closets, and vents for heating and cooling.

Some examples of bedrooms that have worked well to hold a King-sized bed are as follows. A bedroom that is 14 feet by 19 feet can comfortably hold a King-size Bed, two nightstands on either side of the bed, a love seat, ottoman, TV stand and a dresser. Another bedroom that is smaller at 12 feet by 12 feet can hold a King-sized bed with two nightstands and a dresser.
