Wheelbase has an effect on turning radius and stability, but it is minor and should not be a big concern for a beginner driver. Tail and nose: Both are measured between 5 and 7 inches from the center of the outermost truck mounting holes. Except for old school or unusually designed skateboards, the nose can be significantly longer and broader than the tail. Typically, the front of the board is more heavily used than the back and thus wears out first. Length: The length of the board is how far it goes when you step back with both feet. A common length for a skateboard is 14 inches, which is long enough to learn most tricks but not so long that it gets in the way of having fun. There are many different types of skateboards, each with its own unique features.
