what is the measurement of a california king quilt
California or Western King Bed. A California or western king bed's mattress measures 72 inches in width and 84 inches in length. For the best fit, choose a comforter that's 86 to 102 inches wide and 94 to 102 inches long. If your mattress is extra deep -- greater than the standard 7 inches -- pick a longer, wider comforter that will cover it on all sides.
