Nowadays it is easier to find this type of information online. Also you can ask your local skateboard retailers. For beginners it is always better to go for wider boards. They should also buy a cheaper skateboard to learn the basics on, because not everyone is comfortable with this sport. So you don’t want to place too much investment into that initial skateboard. You should look into every aspect of it. How does the deck feel when you stand on it? Are the size and style of wheels going to work for you as well? Take it for a spin to try out the types of events you want to perform on it. If the retailer isn’t willing to let you do so, then go find one some where else.
