What size snowboard should I get?

Don't listen to Tmonster ...some horrible advice......Your height means very little. At your weight I would go anywhere from 140 to 148 range. And as the other poster recommended I would have to disagree and say go for a true twin snowboard over a directional board especially if you plan on riding park and learning to ride switch it will be a huge help. If you plan to learn park go closer to the 140 range if your looking to ride all around lookin in the higher range
