What size skateboard do I need?
Contrary to what you might think, width is the most important part of choosing a skateboard deck, not length or wheelbase. Skateboard decks vary in width from 7.5" to 8.25". The width you need depends on your height, shoe size, skating style, and personal preferences.
Perhaps one of the most important factors in choosing the proper board width is shoe size. Turning, ollieing, and doing technical tricks requires a good fit between foot and board. This is why "skate shoes" are actually a thing. Selecting a deck that is not too wide for your feet and not too narrow is important. Check out this graphic for some help:

If you choose a board with a too-large width for you, you will need to exert excessive power, which can make skateboarding and trick riding difficult. If you choose a board with a too-small width for you, you'll have trouble balancing and won't feel stable. Most teen and adult riders will want at least a 7.5" width, but a wider board may feel more stable depending on your build and shoe size. Below are some general guidelines.
