Features of Skateboard Decks
Width
The key measurement of every skateboard is the width and this is how most boards are divided up into groups. Narrower decks for smaller feet and shorter riders, wider decks for bigger feet and larger riders. It is very important to select the correct skateboard truck size to fit the width of your deck. The axles of your trucks (full width of the truck) should not exceed the width of the deck.
Length and Wheelbase
The length of a skateboard deck is most obvious as a tip-to-tip measurement. Generally speaking, the wheelbase will increase in proportion to this and is the measurement from the inner to inner bolt holes. Short wheelbase for kids or those that want a quick responsive board for flip tricks, longer wheelbase for taller riders and those that want to skate faster and larger transition ramps and bowls
Concave
The concave is the radial curve across the width of the deck that locks your feet into the board. It also allows you to have a greater feel of where your feet are on the skateboard
Nose and Tail Kicks
Nose and tail kicks are a feature of skateboards so you can complete tricks like ollies and kickflips. Generally speaking, the tail kick is shorter and steeper to allow extra leverage and the nose is shallower but longer to make it easier to catch it with your front foot. The difference between the nose and the tail is subtle but important.
Construction
Most skateboards are made from 7 plies North American hard rock maple. This material allows for the best strength-to-weight ratio for good performance. For a premium ride, manufacturers will often add a layer of carbon fiber to the deck to increase the torsional stiffness and add an extra level of pop that lasts longer than an entirely hard rock maple deck. Occasionally a single veneer of some more exotic wood is added to the top or bottom layer purely for aesthetic purposes like teak, oak, bamboo, zebrawood, or some other material
