A California King mattress measures 72 inches wide by 84 inches long, making it one of the longest standard mattress sizes available. In feet, California King dimensions are approximately 6 feet wide by 7 feet long, while the metric measurements are about 183 centimeters wide by 213 centimeters long. This extra length provides more room to stretch out, making a California King mattress a popular choice for taller sleepers, couples who prefer additional legroom and bedrooms with a narrow, elongated layout. The California King size offers four inches more length than a standard king mattress, but it is four inches narrower, so comparing mattress measurements is important before choosing the right bed. A California King bed requires more than 72 by 84 inches of open floor space because the bed frame, headboard and clearance around the mattress add to its overall footprint. For comfortable movement, many bedrooms should be at least 12 feet by 10 feet, although the best room size depends on the frame style, furniture placement and desired walking space. Shoppers should also confirm that California King sheets, mattress protectors, comforters and bed frames match the 72-by-84-inch mattress measurements, since standard king bedding and foundations are not interchangeable. Measuring doorways, stairways and hallways before delivery can also help ensure that the California King mattress and bedroom furniture can be moved into the room easily.

What are the standard measurements of a California king mattress? + -

A standard California king mattress measures 72 inches wide by 84 inches long, or 6 feet by 7 feet.

How does a California king compare with a standard king in length? + -

A California king is 4 inches narrower and 4 inches longer than a standard king, making it a better fit for sleepers who prefer additional length.

What room measurements work well for a California king? + -

A room that is at least 12 feet by 12 feet generally provides enough space for a California king, surrounding furniture and comfortable movement.

How much space should be left around a California king bed? + -

Leave at least 24 to 30 inches of walking space along the sides and at the foot of the bed whenever possible.

Do California king bed frames have the same measurements as the mattress? + -

No. A California king bed frame is usually slightly wider and longer than the mattress to accommodate the frame materials and support system. Check the frame's listed dimensions before arranging the room.
