Freestyle skateboard decks come in a range of sizes and shapes. It's good to know what
Length - The distance from the tip of a skateboard's nose and the end of a skateboard's tail. Freestyle skateboard decks are usually 26" - 30" long.
Width - Freestyle skateboard decks are usually 7.25" - 8" wide.
Wheelbase - The distance between the front truck bolts and rear truck bolts. Freestyle skateboard wheelbases are usually 11.5" - 13.75" long.
Nose - The front section of a skateboard, usually measured from the front truck bolts to the front of the board.
Tail - The back section of a skateboard, usually measured from the rear truck bolts to the end of the board.
Double Kick vs. Single Kick
Although freestyle skateboards come in many unique shapes, most decks feature one of two "kick" styles - Double kick or single kick
"Kick" - This refers to the upturned nature of a tail or nose.
Double Kick - A skateboard that has an upturned nose and upturned tail
Single Kick - A skateboard that has an upturned tail and flat nose
Concave refers to the longitudinal curvature of the skateboard deck. Freestyle skateboard decks come in a range of concave heights and styles. In general, freestyle boards are mellower than the average street skateboard.
Profiles (a.k.a. Shapes)
Freestyle skateboard profiles can be grouped into two categories - Symmetrical shapes and asymmetrical shapes.
Symmetrical - The nose and tail have the same dimensions, kick angles, and curvature
Asymmetrical - The nose and tail have differing dimensions and/or curves
You may have seen a freestyle deck and wondered "What are those plastic things on the nose and tail?"
Skid Plates - Abrasion resistant guards that can be mounted on the underside of the nose and tail of a skateboard to prevent wear.
Why Use Skid Plates? - Freestyle skateboard tricks involve a lot of tail dragging. Skid plates protect the tail of your skateboard from damage caused by tail drags and help you to avoid "razor tail".
