You can find a "Size Guide" link on each product web page or another good starting point is to measure your height and inseam. There are many other factors necessary to ensure the perfect fit and the most accurate way to find out what size bike you need is to be fit by a shop professional. Shop staff will take all the necessary measurements to determine a rider's requirements for top-tube length, seat-tube length and saddle height, as well as other factors such as stem length and angle, crank length and saddle fore/aft positioning. These measurements vary significantly from person to person — even if the same height. We, therefore, strongly recommend that you visit your local Fuji store to determine the perfect size for you.
