Most boards measure 84 to 150 centimetres (33 to 59 in) in length while widths vary from 22.8 to 25.4 centimetres (9.0 to 10.0 in). There are several longboard shapes, such as pintails, swallowtails, flat-nose riders, drop-through decks, drop decks and boards with the same shape as a standard skateboard.
For additional info visit our. Skateboard Decks Buying Guide. Length is measured from the tip of the nose to the tip of the tail. Average board length is 28- 32 and longboards can range 32 and larger, but length is only referred to by advanced skaters.
