What is the correct trekking pole height for a 1.70m tall person?

For a 1.70m (5'7") person, the correct flat-ground length is approximately 115–120 cm. The rule: stand upright with the tip on the ground beside your foot; adjust until your elbow is at a 90° angle. For ascents, shorten by 5 cm (to 110–115 cm); for descents, lengthen by 5 cm (to 120–125 cm). Arm length, posture, and footwear can affect the exact height. Mark your ideal flat-ground length with tape for quick reference.

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 1.70 m, 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

1. Stand upright – Wear the shoes you will be walking in. This is important because shoe thickness can affect the length.
2. Place the tip on the ground – The tip should be beside your foot, on the ground.
3. Adjust the pole – Move the sections until your elbow is at a right angle (90°). Your forearm should be parallel to the ground.
4. 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 1.70 m 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.

8. Pro tips for Brazilian hikers

• Try before you buy – Visit Decathlon or Adventure Sport and test the length.
• Mark your poles – Use tape to mark your flat length.
• Adjust for terrain – Shorten for ascents, lengthen for descents.
• Use lever locks – They are easier to adjust than twist locks.
• Check length before each walk – Locks can slip; check and adjust if needed.

9. Final verdict

For a 1.70 m 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. With the correct height, your poles will provide comfort, support, and efficiency on any terrain. Happy hiking!
