A clear guide to picking the right size so you feel stable, paddle straighter, and enjoy your first sessions.
Ever stepped on a paddle board and instantly wobbled into the water? Nine times out of ten, it’s because the board’s the wrong size for you. The right length, width, and thickness can turn that shaky first try into a confident, smooth ride and that’s exactly what we’re going to help you find.
If you’re a beginner, the wrong size can make learning frustrating. The right size will have you standing confidently, paddling straight, and smiling like you’ve just mastered a new superpower.
Below, we’ll break down the three key measurements length, width, and thickness, so you can find your perfect match. We’ll also share real examples from the Aquaplanet range so you can see how these specs translate into real-world boards.
1) Length: How Long Should Your Paddle Board Be?
Length plays a big role in speed, tracking, and manoeuvrability.

- Shorter boards (under 10’): More manoeuvrable and easier to turn, but slower in a straight line. Great for kids, lighter paddlers, or narrow, twisty waterways.
- Medium (10’–11’): The beginner sweet spot. Stable, still playful, and good in mixed conditions.
- Longer (11’+): Straighter tracking and more glide per stroke, ideal for touring or covering distance.
SUGGESTED boards
Medium: MAX 10'6": versatile all-rounder for most beginners.
Long: MAX Plus 11’8”: extra glide for long rivers or coastal stretches.
2) Width: Why Stability Starts Here
Width determines how stable your board feels underfoot.

- Narrow (under 30”): Faster and more efficient for experienced paddlers, but less forgiving for beginners.
- Mid-width (30”–32”): The sweet spot for most new paddlers.
- Wide (33”+): Maximum stability, slightly slower due to more surface area in the water.
SUGGESTED boards
Mid-width: MAX 10'6" (31" wide): The ultimate all-round SUP with unbeatable balance and standout looks.
Mid-width: PACE 10’6” (32” wide): big, confidence-boosting platform for absolute beginners.
Mid-width: PACE 11'8" (32” wide): big, confidence-boosting platform for absolute beginners or heavier paddlers.
3) Thickness: Float, Stability, and Weight Capacity
Thickness affects how much weight the board can carry and how rigid it feels.

- 4” boards: Lower to the water and lighter, but less volume and capacity. Best for kids or very light paddlers.
- 5” boards: A middle ground, lighter than 6”, with decent capacity for small-to-average adults.
- 6” boards: The default for adults. Rigid, buoyant, and happy carrying pets, kids, or camping gear.
SUGGSTED boards
6" thick: Aquaplanet MAX 10’6” (6” thick): wider outline and full-length deck pad for comfort.
6" thick: Aquaplanet PACE 10’6” (6” thick): wider outline and full-length deck pad for comfort.
4) Putting It Together: Choosing the Right Size for You
- Your height & weight: Heavier paddlers need more volume (longer/wider/thicker).
- Where you’ll paddle: Lakes & canals favour stability; open water & touring reward extra length.
- What you’ll do: Cruising = all-round 10’6”. Long trips = 11’+. Yoga/fishing = wider boards.
- Carrying extras: Kids, dogs, or camping kit? Go bigger.
