What size snowboard should I ride?

I post this every month as it gets a tremendous number of views.

This is the site I send people to  most of the time. It's got a formula that calculates your needs based on a variety of criteria. I'd add 2 - 3 cm if you ride a lot of powder. It even recommends boards. This is a great place to start. But, you're spending a lot of money. Check thoroughly.

Here's a much deeper look at the subject, including (if you go to the bottom) information on board widths. There's some good info here.

Finally, here's the backcountry.com data.
