What is the correct trekking pole height for a 170cm person?

For a 170 cm (5'7") person, the standard flat‑ground length is approximately 115–120 cm. The rule is: elbows at 90° when the tip is on the ground. Here is a step‑by‑step guide to finding the correct height, with adjustments for ascents and descents.

1. The standard rule – elbows at 90°

The most widely accepted rule for setting trekking pole height is:

• Stand upright with the tip of the pole on the ground beside your foot.
• Adjust the pole until your elbow is at a 90° angle.
• This is your correct flat‑ground length.

For a person of 170 cm, this typically results in a length of 115–120 cm. However, this can vary slightly depending on arm length and torso proportion.

2. Step‑by‑step adjustment

a. Stand upright – Wear the shoes you will be walking in. This is important because shoe thickness can affect the length.
b. Place the tip on the ground – The tip should be beside your foot, on the ground.
c. Adjust the pole – Move the sections until your elbow is at a right angle (90°). Your forearm should be parallel to the ground.
d. Check both poles – Ensure both poles are set to the same length.

3. Adjustments for terrain

• Flat ground – Use your standard length (115–120 cm for a 170 cm person).
• Ascents – Shorten the poles by 5 cm (to 110–115 cm). This lowers your hands, giving you better leverage to push up the slope.
• Descents – Lengthen the poles by 5 cm (to 120–125 cm). This allows you to plant the pole ahead of your feet, creating a braking effect that reduces knee impact.

4. Marking your poles

Once you have found the correct length for flat ground, mark it on the pole with a piece of tape or a permanent marker. This makes it easy to reset the length on the trail.

5. Factors that affect the perfect length

• Arm length – Someone with longer arms may need a slightly longer pole; someone with shorter arms may need a shorter pole.
• Posture – If you have a stooped posture, a slightly longer pole (117–122 cm) may help you stand straighter.
• Footwear – Thicker soles (e.g., walking boots vs. trainers) will affect the length. Adjust accordingly.

6. Testing the length

The best way to find the perfect height is to try a few settings on a flat surface. Walk a few steps, plant the poles, and see how it feels:

• Too short – You will have to lean forward, straining your back.
• Too long – You will have to reach up, straining your shoulders.
• Just right – Your arms are relaxed, elbows at 90°, and the poles feel natural.

7. Pro tip for older adults

For older adults or those with reduced strength, a slightly shorter pole (2–3 cm less) can lower the centre of gravity, improving balance. For those with a stooped posture, a slightly longer pole can encourage a more upright stance.

8. Final verdict

For a 170 cm person, the correct flat‑ground length is 115–120 cm. This is based on the 90° elbow rule. Adjust by 5 cm for ascents and descents. Mark your poles for easy reference, and test the length on a flat surface before hitting the trail. The perfect length is the one that feels natural and allows you to walk with a relaxed, upright posture. With the correct height, your poles will provide comfort, support, and efficiency on any terrain.
