Trekking Pole Length Calculator

How to Measure Your Trekking Pole Length

The correct trekking pole length places your elbow at a 90-degree angle when the pole tip touches the ground beside your foot. Stand upright in your tramping boots, hold the pole grip with arms relaxed at your sides, then bend your forearm forward. Your elbow should form a right angle with your upper arm. This position allows optimal weight transfer from your upper body to the poles, reducing strain on knees and ankles during long NZ tramping days.

Use the calculator above to find your base pole length using the standard formula: Height (cm) × 0.68. This calculation works for flat terrain and provides a starting point for adjustment. For steep Great Walks routes like the Routeburn Track or Kepler Track, you will need to adjust pole length based on gradient. The calculator recommends your base length, which you then shorten for uphill sections and lengthen for downhill sections throughout your tramp.

Adjusting Pole Length for NZ Terrain

New Zealand's steep, varied terrain demands different pole lengths for different sections of track. On uphill climbs like the Tongariro Alpine Crossing's Devil's Staircase or Kepler Track's Mt Luxmore ascent, shorten poles by 5-10cm from your base length. Shorter poles let you plant poles higher on steep grades, maintaining the critical 90-degree elbow angle while pushing upward. This transfers more power to your legs and helps you maintain balance on loose volcanic scree or muddy bush tracks.

For steep descents like McKinnon Pass on the Milford Track or descending from Key Summit on the Routeburn, lengthen poles by 5-10cm from your base. Longer poles plant farther ahead on downhill sections, reducing forward lean and taking massive strain off knees. On a 1,000-metre descent carrying a 15kg pack, properly adjusted poles can reduce knee impact forces by 25-30%, preventing the joint pain that ends multi-day tramping trips early.

This is why adjustable poles are essential for NZ tramping. You start at your base length, shorten for the climb up, return to base on the saddle, then lengthen for the descent. The Routeburn Track alone requires dozens of adjustments over three days. Telescopic poles with reliable locking mechanisms let you adapt in seconds, optimizing performance for every terrain change without stopping to fumble with pole sections.

Why Pole Length Matters for Great Walks

Great Walks routes showcase New Zealand's most dramatic terrain, from alpine passes to coastal forests, and incorrect pole length creates problems fast. Poles set too short on flat sections force you to hunch forward, causing back pain after hours of tramping. Poles too long on steep climbs make you overreach when planting, wasting energy and reducing stability on technical terrain. River crossings on the Routeburn or Hollyford require precise pole placement, where incorrect length means poor balance in swift water.

Weight distribution becomes critical on multi-day Great Walks tramping. A properly fitted pole transfers 25-30% of pack weight to your arms and core, protecting knees on descents and providing power on climbs. Over a four-day Kepler Track circuit or five-day Milford Track journey, this weight reduction prevents overuse injuries that plague trampers using incorrect pole lengths. Calculate your base length, then invest in quality adjustable poles that let you optimize for every terrain change.

Telescopic vs Fixed Length Poles

Telescopic poles offer infinite adjustment within their range, typically 95-135cm, letting you dial in your calculated base length plus terrain adjustments. Flick-lock or twist-lock mechanisms provide quick adjustments during tramping, essential for routes with varied elevation like the Tongariro Alpine Crossing's 700-metre ascent followed by 1,100-metre descent. Quality telescopic poles lock securely without slipping under load, critical when trusting poles on river crossings or steep scree slopes.

Fixed-length poles eliminate adjustment mechanisms, reducing weight and potential failure points. However, they lock you into one length for all terrain, making them unsuitable for NZ's varied Great Walks. You would need poles set at your base length, then manually swap to longer poles for descents and shorter poles for climbs. This impractical approach is why 95% of Great Walks trampers choose adjustable poles. Our calculator gives you the base length to set your telescopic poles.

Foldable Poles and Pack Size

Foldable trekking poles collapse to 30-40cm via internal shock cord, fitting inside or strapped to backpacks when scrambling or using hands on technical sections. The Routeburn Track's Harris Saddle and Milford Track's Mackinnon Pass both feature sections where poles get stowed for hand-over-hand climbing. Foldable poles deploy in seconds when terrain opens up again, ready for steep descents without fumbling with telescopic sections.

Most quality foldable poles still offer some length adjustment via telescoping top sections, giving you 10-15cm of range from your base setting. This lets you optimize for major terrain changes while maintaining compact pack-down size. Pack-down matters for international trampers flying to NZ for Great Walks. Foldable poles fit in checked luggage without exceeding airline length restrictions, while full-length telescopic poles may need to ship separately.

Choosing the Right Pole Length Range

When buying poles based on your calculated length, ensure the adjustment range covers your needs. If your base length is 115cm, look for poles adjustable from 100-130cm minimum. This gives you 15cm shorter for steep climbs and 15cm longer for steep descents. Poles that barely reach your base length cannot extend for downhill use, while poles that max out just above your base cannot shorten enough for sustained uphill work.

Tall trampers over 185cm need poles extending to 135cm or more for downhill sections. Many budget poles max out at 135cm, forcing very tall trampers toward premium models with extended ranges up to 145cm. Short trampers under 155cm need poles adjusting down to 95cm or less for uphill sections. Our calculator accounts for your height and recommends the appropriate adjustment range when you shop for poles.

Pole Length for Different Activity Types

Easy coastal tracks like Abel Tasman require minimal adjustment. Set poles to your calculated base length and make minor tweaks for beach vs bush sections. Day hikes on varied terrain benefit from your base length as the starting point, with frequent adjustments for elevation changes. Great Walks demand constant optimization, adjusting 10-20 times per day for NZ's dramatic terrain changes.

Alpine and technical tramping requires aggressive adjustment ranges. Steep alpine approaches need poles shortened to 85-90% of base length, while exposed ridge descents require poles lengthened to 115-120% of base. This is why alpine trampers choose poles with maximum adjustment range, ensuring they can optimize for extreme terrain without running out of adjustment capacity. Calculate your base, then add 20cm range both directions for alpine use.
