most boards are in length. widths vary from . longboard are made in many shapes. these include pintails, swallowtails, flat-nose riders, drop-through decks, drop decks and boards with the same shape as a regular skateboard. pintails have looser trucks and larger wheels. they are better suited for carving or a "smooth" feel. drop decks and drop throughs let the rider be closer to the ground. this gives them a lower center of gravity which increases stability. this also makes the boards better for downhill racing. mid-length boards, have many different uses. they have more weight and bulk. this makes them move with a fluid motion by providing more momentum. the longboard's design lets rider make big turns or quick short carves. these movements are similar to the motions of surfers or snowboarders.
