Size Guide

Deck Sizing

Choose deck width based on your style, terrain, and shoe size.
Length and wheelbase vary by shape; width is the key starting point.

Deck Width Best For Notes
7.5″ – 7.8″ Youth, smaller riders Lighter, quicker flips; less foot space.
8.0″ - 8.125" All-around street/park Great starting point for most skaters.
8.25" – 8.3″ Street & park balance More landing room; still flicks well.
8.5″ - 8.75 Park, bowls, transition Extra stability and control at speed.
9.0" + Vert, cruise, bigger feet, Swampy Stable ride; flips feel heavier.

Shoe size tip: US Men’s 6–8 ≈ 7.75–8.0″ • 9–11 ≈ 8.0–8.5″ • 11.5+ ≈ 8.5″+. Preference varies.

Truck Sizing

For best performance, match truck axle width to deck width.
Sizing Labels vary by brand—use this as a quick reference.

*Size names differ slightly by brand/series—check each product page for exact fit.

Wheel Sizing

Pick diameter for terrain/speed and durometer for hardness/grip.

Diameter Use Ride Feel
50–53 mm Tech street, smooth parks Quick pop & flip; least speed over cracks.
52–54 mm All-around street/park Balanced speed/control; most popular.
54–56 mm Park, bowls, small transition More roll speed; stable landings.
56–60+ mm Rough streets, cruiser, big transition Faster over cracks; heavier feel.
  • Durometer: 99A = classic street; 101A = harder/faster (smooth parks); 78A–87A = soft/cruiser/rough ground.
  • Contact patch: Wider = more grip/stability; narrower = easier slides.
  • Wheelbite tip: Bigger wheels may need risers and/or firmer bushings.

Clothing Sizing

Clothing sizes vary by manufacturer/brand. For the most accurate fit, please refer to the Size Guide on each product page—measurements are provided per brand and style.
