The nose length is measured from the forward contact point of the board to the tip of the nose. If you put the board on the ground and measure from where the nose starts to kick up to the end, this will be the nose length. Freeride boards have a longer nose length to help the snowboard float through the snow.
Tail Length
The tail length is measured from the rear contact point of the board to the tip of the tail. If you put the board on the ground and measure from where the tail starts to kick up to the end, this will be the tail length.
