How do I select my ski size?

Backcountry skis sizes (cm) are recommended based on skier height. The lowest height range for a ski (ex. 5'2 for a 163cm ski) is recommended for advanced/expert skiers. The high end of the suggested height range (ex. 5'9" for a 163cm ski) is recommended for beginner skiers.
