How do you choose the right ski pole length?
To find out which size you need, hold the pole upside down and vertically, with your hand under the basket. Your arm should be at a 90° angle with your body.
If you are purchasing your poles online and don't have the opportunity to try them out, measure your height in centimetres and multiply it by 0.7. The result will give you an approximate of the ski pole length you need in centimetres. if you're 1.80 m tall (i.e. 180 cm), they should be approximately 126 cm long (180x0.7).
Note that when ski touring, pole length varies: you will appreciate having longer poles to help you on the ascent. Telescopic ski poles are a good solution for varying their size when climbing or descending.
