Sizing a surf skate is not the same as sizing a regular skateboard or longboard. The rules are different, the numbers that matter are different, and getting it wrong is more consequential because the surf skate's front truck system is far more sensitive to wheelbase than a standard skateboard truck. Here is how to get it right.
The Number That Actually Matters — Wheelbase, Not Length
Most people approach surf skate sizing by looking at deck length and comparing it to their height. This is the wrong starting point. Two boards can be the same length but have completely different wheelbases and feel entirely different underfoot. The Carver Omni and the Carver Black Tip are both 32 inches long — but their wheelbase differs meaningfully, making them suit different riders and different riding styles. The Carver RNF is 29.5 inches — shorter than both — yet has a wheelbase of 16 inches, larger than many 32 inch boards.
The wheelbase — the distance between the inner bolt holes of the front and rear truck mounting positions — determines how the board turns and how it feels when you pump. A shorter wheelbase produces tighter, snappier turns with a shorter arc. A longer wheelbase produces more drawn-out, flowing turns with more stability at speed. On a surf skate, where the front truck can swing through a wide range of motion, a few centimetres of wheelbase difference is felt immediately.
Lead with wheelbase. Then consider deck length. This is the order that produces the right board.
Matching Wheelbase to Your Surf Stance
If you surf, the most precise way to size a surf skate is to match the wheelbase to your surf stance — the distance between your feet when you are in your natural surfing position on a wave. When you stand on the surf skate with your feet at the same width as your surf stance, and your rear foot positioned over the tail, your front foot should sit approximately over the rear bolts of the front truck. This is the functional surfing position and the one from which the pump technique operates correctly.
How to measure your surf stance: stand on a surfboard on land in your natural riding position. Measure from the middle of your rear foot to the middle of your front foot. That is your stance width.
As a general guide based on average stance widths by height:
- Under 165cm height: approximately 14 to 16 inch wheelbase
- 165 to 175cm: approximately 16 to 18 inch wheelbase
- 175 to 185cm: approximately 17 to 19 inch wheelbase
- Over 185cm: approximately 19 to 21 inch wheelbase
These are starting points, not fixed rules. Your actual surf stance, your surfboard length and your riding style all affect the ideal wheelbase. Shortboard surfers typically want a shorter wheelbase matching their narrower surf stance. Longboard surfers and those who ride mid-lengths typically want a longer wheelbase to match their wider stance.
Note on Truck System Measurements
One important technical point: wheelbase and truck distance are not always the same measurement, and different brands measure differently. YOW and most spring-loaded systems measure truck distance as wheelbase plus approximately 2 inches. Carver measures true wheelbase between the inner bolt holes. When comparing specs across brands, check which measurement the brand is using — otherwise you will be comparing numbers that mean different things.
Deck Length — How It Relates to Wheelbase
Once you have a target wheelbase range, deck length becomes a secondary consideration. For most adult riders, a deck length in the 30 to 34 inch range covers the full wheelbase range needed. Outside this range:
Under 30 inches: suits younger riders, smaller frames and those who want a very tight, manoeuvrable setup for technical riding in limited space. Not the right choice for taller riders regardless of how surfy it looks.
34 inches and above: suits larger frames, longboard surfers who want a more relaxed flowing style, or riders who want maximum stability for cruising at higher speeds. At the top end of the range the board starts to behave more like a longboard cruiser than a surf training tool.
Deck Width
Deck width affects how much platform you have underfoot. Most surf skates run between 9 and 10.5 inches wide. Wider decks give more stability and suit a wider surf stance — the feeling is closer to standing on a surfboard. Narrower decks are lighter, more responsive and suit technical riding and smaller frames.
For most adult surf skate riders, a width between 9.25 and 10 inches covers the range well. Go narrower for a more technical feel, wider for more stability and a more surfboard-like platform.
Choosing by Riding Goal
Surf training — shortboard: prioritise matching your wheelbase to your actual surf stance. A shorter wheelbase in the 15 to 17 inch range suits most shortboard surfers. Carver CX for controlled training, Carver C7 or YOW Meraki for maximum surf simulation.
Surf training — mid-length or longboard: longer wheelbase in the 18 to 21 inch range. More flowing turns, more stability, matches the wider stance of longboard surfing. Carver Kai Lenny Atmosphere or similar longer shapes.
Cruising and lifestyle riding — not surf training: deck length and width matter more than precise wheelbase matching. Choose something comfortable underfoot in the 31 to 34 inch range with a width that suits your foot size. Globe and Landyachtz completes in this range are well suited.
Technical riding and skateparks: shorter wheelbase for tighter turns, more concave deck for foot lock-in, harder wheels for skatepark surfaces. YOW Performance series or shorter Carver shapes.
Beginners — Start Longer and Wider
A common mistake beginners make is choosing a shorter board because it looks more like a high-performance surfboard. Shorter wheelbases are more reactive and more difficult to control when you are still developing the pump technique. A slightly longer wheelbase with a wider deck is more stable, more forgiving and more enjoyable when you are learning. You can always move to a shorter wheelbase as your technique develops — going the other direction is much harder.
For beginners: 30 to 33 inches deck length, 9.5 to 10 inches wide, 16 to 18 inch wheelbase, Carver CX truck system. This is the setup that gives you the most margin for error while still delivering genuine surf feel.
Not Sure? Come In
Sizing a surf skate from a spec sheet is harder than it sounds. The best way is to stand on a few boards, feel the wheelbase under your feet, and get a recommendation from someone who rides them. Come into our Richmond store — we have the Carver, YOW, Landyachtz, OBFive and Globe ranges in stock and staff who surf skate and can match you to the right setup based on your height, surf background and what you want to do with the board.
