Hey, im 6ft 3 and weigh 175lbs my boot size is 13.5 ,I need to know the length+width of a snowboard for me?

i weigh about 175lbs and i freeride, meaning everything on the mountain so i need a snowboard that be good for everything for my size, and i already know that i need a wide board so i dont have overhang meaning my boots dont hang over the board but i need to know how wide it should be. it would be great if someone could help me that might have the same body type or someone that knows about sizes
