This pattern is for the beanie/chemo cap only. Beanie is approx. 7 1/2 inches in length (top-bottom) and approx. 20inches in circumference. This is an adult female size. Rows 1 - 7 is the crown and measures approx. 7in x 7in. To get your gauge, complete the crown (rows 1 - 7) and then measure the circumference. You may need to go up a hook size and/or use a looser tension if your crown is smaller than 7 x 7 or go down a hook size if you have looser tension and your crown is larger than 7 x 7.
