What snowboard size do i need?

Question

am 5foot10in and 120 what size what length width and that stuff

Answer 1

I'd go with a 152cm, with a soft flex, since you are kinda on the light side.  Width is based on boot size.  If you are boot 11 and up consider getting a wide board.  I'm gettin one, and I wear size 11 boot.

Answer 2

Im 5 10 and weigh 140 and i ride a 157.. It depends though on what you like to do...If i were to only ride freestyle i would prolly get a 154, but i ride all around so i think 157 fits me perfect. Since you weigh 120 a softer board would work good for you....but it all depends one what type of boarding you want to do.
