Sorry 1 more post haha size and width are both preference. my boyfriend likes longer/wider boards, i like shorter/wider boards. I am 5'5 and I weigh 190... I know I'm overweight lol but I'm a hell of a snowboarder and I have a lot of muscle
I'm also a size 8. I find it easier on a shorter board because I have more control (or so I think in my head). My boyfriend prefers longer for speed I think.
