Choose your ideal board size range using your body weight and boot size.
To decide between two sizes, choose the smaller size if your priority is maneuverability and freestyle performance, choose the larger size if you're focused on riding fast and powder performance. A shorter board will be easier to turn and a longer board will offer better float and stability riding off-piste.
