Trekking Pole Length Calculator
Find your ideal trekking pole length from your height, with adjustments for climbing and descending.
How it works
flat length ≈ 0.68 × height · uphill ≈ −5 cm · downhill ≈ +7.5 cm (elbow at 90°)
The right trekking-pole length puts your elbow at a comfortable 90-degree bend when the tip is on the ground beside you, which works out to roughly 68% of your height. On sustained climbs you shorten the poles a few centimeters to keep that angle, and on descents you lengthen them so you are not hunched over. Adjustable poles let one pair cover the whole range, which is why the recommended span here spins around the flat-ground figure.
Worked example
At 68 in (173 cm) tall: 173 × 0.68 ≈ 118 cm on flat ground. Shorten to about 113 cm going up and extend to about 125 cm coming down.
Frequently asked questions
How do I know the length is right?
Stand on flat ground and hold the pole with the tip by your foot; your forearm should be roughly horizontal, elbow bent 90°. If your hand is above your elbow, shorten the pole.
Why change length on hills?
On climbs, shorter poles keep the 90° elbow angle and let you push efficiently; on descents, longer poles reach downhill so you stay upright and save your knees.
Do I need adjustable poles?
Fixed-length poles are lighter but only ideal on flat terrain. Adjustable poles are more versatile for varied trails and let more than one person share a pair.
