King Bed vs. California King Bed

Shopping for a mattress can be a very a tough decision, especially if you have a large master bedroom. In most cases, the choice comes down to two types of king beds: a standard king size bed and a California king size bed. Both kinds are meant to create maximum comfort and bring perfect balance to a big bedroom. However, there are some important factors worth weighing when choosing between a king or California king bed.

King Size Beds

Advantages of a King Size Bed

  • Wider mattress - The additional width creates more space for sleepers to spread out. It also makes a king bed the best option for couples.
  • Available bedding - Since standard king models are more common, sheets, comforters and other bedding can be found in a wider variety of styles and colors.
Limitations of a King Size Bed
  • Short surface for very tall sleepers - While king size beds can accommodate most tall people, very tall people might require more length.
  • Harder fit in narrow bedrooms - If you have a narrow master bedroom, the width of a regular king bed might make the room cramped.

California King Size Beds

Advantages of a California King Size Bed

  • Best for tall sleepers - A California king bed is meant for sleepers that are extremely tall. Its longer mattress provides more leg room, especially if you are taller than 6 feet 4 inches.
  • Easier fit in narrow bedrooms - If you still want plenty of space to spread out but your master bedroom is too narrow, a California king bed is a good compromise. While it's longer, a California king is four inches narrower than a standard king bed.
Limitations of a California King Size Bed
  • Less space for couples - The smaller width might create tighter space for couples sharing a bed.
  • Limited selection of bedding - Since a California king has unique dimensions, its bedding accessories could be more difficult to find than those for a regular king size bed.
