CAL. GOV. CODE § 420 : California Code - Section 420

The Bear Flag is the State Flag of California. As viewed with the hoist end of the flag to the left of the observer there appears in the upper left-hand corner of a white field a five-pointed red star with one point vertically upward and in the middle of the white field a brown grizzly bear walking toward the left with all four paws on a green grass plot, with head and eye turned slightly toward the observer; a red stripe forms the length of the flag at the bottom, and between the grass plot and the red stripe appear the words CALIFORNIA REPUBLIC.

Dimensions, excluding heading and unfinished flag ends: The hoist or flag width is two-thirds of the fly or flag length; the red stripe width is one-sixth of the hoist width. The state official flag hoist widths shall be two, three, four, five, six and eight feet. The diameter of an imaginary circle passing through the points of the star is one-tenth of the fly length; the distance of the star center from the hoist end is one-sixth of the fly length and the distance from the star center to the top of the flag is four-fifths of the star-center distance from the hoist end. The length of the bear diagonally from the nose tip to the rear of right hind paw is two-thirds of the hoist width; the height of the bear from shoulder tip vertically to a line touching the bottoms of the front paws is one-half the length of the bear; the location of the bear in the white field is such that the center of the eye is midway between the top and bottom of the white field and the midpoint of the bear's length is midway between the fly ends. The grass plot in length is eleven-twelfths of the hoist width and the plot ends are equidistant from the fly ends; the average width of the plot between the rear of the left front paw and the front of the right rear paw is one-tenth of the grass plot length. The height of the condensed gothic letters, as shown on the representation, is one-half of the red stripe width and they occupy a lineal space of two-thirds of the fly length with the beginning and ending letters of the words equidistant from the fly ends.
