When choosing a skateboard, consider your weight and height before deciding what size board to go for. The heavier and/or taller you are the better off you'll be on a larger, wider board, however you may prefer to start off on a larger board anyway to provide you with stability until you decide what style of riding you are going to adopt. Decks are usually made from layers of laminated wood plys (usually 7) and vary in length and size. Most deck widths range between 7.5 and 8.5 inches, and lengths, from around 31 to 33 inches. Your choice will depend on the type of riding you want to do. The smaller, lighter decks are usually easier to control and flip. Whereas the larger, heavier decks are more stable and are good for riding transitions or doing stairs and gaps. The rest is down to personal preference in terms of wheel base, nose, and tail length. Most decks (except for some longboards) have a raised nose, tail, and sides. This is called the concave. The depth and overall shape of the concave has a dramatic effect on the response of the skateboard. The deeper the concave, the more aggressive the skater can be with their tricks. The shallower the concave, the more forgiving the deck is for newer skaters. Grip Tape is applied to the top of the deck and provides you with traction. There are loads of different colors & graphics available but they all do the same basic job.
