How Big Is a Queen Vs. a King Mattress?

There is one standard size for queen mattresses and two standard sizes for king mattresses, eastern and California. Choosing a mattress size depends on the size of your room and the size of the people sleeping on the mattress.
  1. Size

    • A queen-size mattress measures 60 inches wide by 80 inches long. A California king mattress measures 72 inches wide by 84 inches long. An Eastern king mattress measures 76 inches wise by 80 inches long.

    Function

    • Both queen- and king-size mattresses can accommodate two sleeping adults; however, a king-size mattress will probably be more comfortable as long as your room is large enough to hold one.

    Considerations

    • There should be room to walk around on either side and in front of the mattress. If you will not have at least 2 feet of clearance around a king-size mattress, a queen-size mattress will probably be better-suited to your room.

    Tip

    • In addition to measuring your room to see if your mattress will fit, always measure the spaces the mattress will need to fit through to get to your room.

    Warning

    • It is hard to discern the difference between a California and eastern king mattress by just looking. Always measure your mattress before purchasing a bed frame.
