The first and most obvious piece of equipment involved in wakeboarding is the wakeboard itself. A good wakeboard should satisfy various different factors, being large enough to provide a good surface area for the wake boarder to stand on and light enough to make jumps easy. When choosing your wakeboard then it very much comes down to your individual size and shape as well as your level of expertise. If you are a beginner then and are having difficulties balancing on your wakeboard, you should look into getting a larger/wider wakeboard in order to make balancing easier and prevent yourself from falling over or into the water.
At the same time though, a larger and wider wakeboard is going to obviously be heavier than a smaller and narrower one. This means that jumps become more difficult both for beginners and for the more experienced wake boarder.
