Find the correct paddle length for your height and paddling discipline.
Unlike generic "add 10 inches" advice, this calculator adjusts paddle length for five different disciplines — recreational paddles are shorter for comfort, racing paddles longer for reach and power.
How long should a SUP paddle be? Your height plus 8–12 inches (20–30 cm). For a 175 cm (5'9") paddler: 195–205 cm paddle for all-around, 190–195 cm for surf, 200–210 cm for touring/racing. Adjustable paddles let you fine-tune on the water. Enter your height and discipline below for an exact recommendation.

Shorter paddle → higher cadence, more control in surf. Longer paddle → more reach, better endurance for touring.
Paddle length is a starting point. Personal preference, arm length and technique all affect the ideal length. Adjustable paddles allow fine-tuning on the water.
Stand the paddle vertically with the blade on the ground. Raise one arm straight up; the handle should reach your raised wrist. This method works for recreational and all-around paddling. Different disciplines require slightly different sizing (see the add-on chart).
Discipline-specific tips
Surf: Handle reaches your forearm, shorter for quick strokes and turns
Recreational: Handle reaches your raised wrist, versatile default
Touring: Handle reaches your raised palm, more reach per stroke
Racing: Add 2–3 cm more than touring for maximum reach and power
If you're between sizes, go shorter for surf and flat-water fitness; go longer for touring and efficiency-focused paddling.
Why discipline changes paddle length
The base formula is: your height plus a discipline-specific add-on. The add-on accounts for how you use the paddle. Surf requires quick, low strokes close to the board; touring requires a longer reach for efficient, powerful strokes.
Add-on values (cm above height)
Surf (+15 cm): Short for fast turns, low paddle angle
Recreational / Yoga (+20 cm): Standard versatile length
Touring (+25 cm): More reach for efficient long-distance strokes
Racing (+30 cm): Maximum reach for power and endurance
The comfortable range (±3 cm) shown in the result accounts for individual preference and arm length variation.
Choosing your paddle type
Adjustable paddles are ideal for beginners and shared use, as you can dial in the exact length on the water and change it between disciplines. Fixed paddles are the performance choice for racing and serious touring because they are lighter and stiffer, transferring more power per stroke.
When to choose each
Adjustable: You're new to SUP, you share a board, or you want one paddle for multiple disciplines
Fixed: You have a dedicated discipline, race competitively, or want to optimise weight and stiffness
Most recreational paddlers never need a fixed paddle. If you're still learning your preferred length, always start adjustable and lock in the fixed size later.

Adjustable paddles let you fine-tune within these ranges. Cut a fixed paddle 2 cm longer than your target and trim down after a few sessions.
Fixed vs Adjustable vs 3-Piece Paddles
Get an adjustable paddle as your first (lets you find your ideal length), then switch to fixed once you know your preferred length (lighter and stiffer). Fixed paddles are the lightest (300–500g), stiffest, and offer the best performance — but they can't be shared or adjusted. Adjustable paddles are heavier (500–700g), offer a 15–20 cm adjustment range, and have slight flex at the joint. 3-piece paddles are the heaviest (600–800g), pack down for travel, have the most flex, and are OK for recreational use only.
Paddle Material — Aluminum vs Fiberglass vs Carbon
Aluminum paddles ($30–80) are heavy at 800–1000g but durable; carbon paddles ($200–500) weigh 300–500g and reduce fatigue on long sessions. Fiberglass ($80–200) sits in between at 500–700g with some flex, a good balance of price and performance for the casual paddler. Carbon is worth it if you paddle 2+ times per week. A carbon shaft with a nylon blade is a good mid-range compromise.
Blade Size — Small vs Large
Smaller blades (80–85 sq in) cause less fatigue at higher cadence; larger blades (90–100 sq in) deliver more power per stroke but tire you faster. Smaller blades are better for light paddlers, surf, and long distance. Larger blades are better for heavy paddlers, racing, and short sprints. Most all-around paddles have medium blades (85–90 sq in), which work for the widest range of paddlers and conditions.
Common Paddle Length Mistakes
A paddle too long causes shoulder pain and early fatigue; too short causes lower back pain from hunching forward. With a long paddle the blade also enters the water at the wrong angle and you'll feel arms tiring quickly. With a short paddle the blade doesn't fully submerge and you lose power. Using the same length for all activities is a third common mistake — surf needs shorter, touring needs longer; an adjustable paddle solves it cheaply.
How to Measure Without a Calculator
Stand straight, raise one arm overhead: the paddle T-grip should reach your wrist for all-around or your palm for touring and racing. This is the traditional "raise your arm" method. It works for all-around but underestimates racing length and overestimates surf length. The calculator above is more precise because it accounts for discipline-specific differences.
Frequently asked questions
How do I measure paddle length?
Stand your paddle vertically with the blade on the ground. Raise one arm straight up; the handle should reach your wrist. This is the classic recreational method. For touring, the handle should reach your fully extended palm; for racing, add 2–3 cm more for extra reach and power.
Fixed or adjustable paddle?
Adjustable paddles are ideal for beginners and shared use because you can dial in the exact length. Fixed paddles are lighter and stiffer, making them the performance choice for racing and serious touring. If you are new to SUP, start adjustable and only move to fixed once you know your preferred length for a specific discipline.
Can I use one paddle for multiple disciplines?
Yes, with an adjustable paddle. Shorten 2–3 cm for surf; lengthen for touring. Fixed paddles are optimised for one discipline, which is why serious racers and surfers use separate paddles. If you primarily paddle one discipline, a fixed paddle at the correct length is the better choice.
Does blade size affect paddle length?
Yes. This calculator assumes a standard recreational blade (≈75–85 sq in / 480–550 cm²). Larger blades need a slightly shorter shaft; smaller blades may work better slightly longer. Blade size also affects joint strain. Smaller blades suit long sessions and recreational use, while larger blades provide more power per stroke for experienced paddlers.
What if my paddle feels wrong after sizing?
Try adjusting ±2–3 cm from the recommendation. If you feel hunched or overreaching on each stroke, the paddle is too long. If you are bending forward excessively and losing power, it is too short. Most issues resolve within a 4–5 cm adjustment range. The comfortable range shown in the result covers most individual variation.
How long should a SUP paddle be for my height?
Height plus 8–12 inches (20–30 cm). For 175 cm tall: 195–205 cm paddle. Shorter for surf (height + 8"), longer for racing (height + 12"). The calculator above gives exact length for your discipline.
Should I get a fixed or adjustable SUP paddle?
Adjustable for your first paddle — it lets you find your ideal length and share with others. Switch to fixed once you know your preferred length, for lighter weight and better performance. 3-piece only if you need to pack it for travel.
What's better — carbon or fiberglass SUP paddle?
Carbon if you paddle 2+ times per week (lighter, less fatigue on long sessions). Fiberglass if you paddle occasionally (good performance at half the price). Aluminum only as a starter or backup paddle.
