When it comes to understanding the size difference between a California king and a king bed, it's important to note that the California king is longer and narrower than a standard king bed.
A standard king bed measures at 76 inches wide and 80 inches long, whereas a California king bed measures at 72 inches wide and 84 inches long. This means that the California king is 4 inches longer than a standard king bed, but 4 inches narrower.
So, to answer your question, a California king is 4 inches longer and 4 inches narrower than a standard king bed. This makes it a great option for taller individuals who need the extra length, but it may not be as wide as a traditional king bed.
Ultimately, the size difference between the two beds comes down to personal preference and the specific dimensions of the space in which the bed will be placed. It's important to consider the measurements and how they will fit into your bedroom before making a decision.
