What Size Skateboard Do you Need? 
Skateboard Size Chart

Most skateboards are around 7.5” to 8" wide, but can be wider or narrower. If you have larger feet, get a wider skateboard deck.

Once you have the basic size in mind, you can tweak it a little depending on what you want to do with your board. If you want to skateboard transition or vert, if you want to ride a lot of ramps or spend most of your time riding at the skate park, then a wider board is a good choice (8” wide or more). If you want to ride around streets more, and do more technical tricks with your board then try to keep it under 8” wide. If you are looking for a skateboard to cruise around on, and don't plan on branching into tricks too much, then a bigger, wider board is always better.
