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.
Tagboard Defined. Tagboard is a lightweight cardboard that comes in many sizes, styles and colors. It is thinner than true poster board and is made from virgin wood pulp. It is not acid-free, so it should not be used for projects that involve keepsakes or photos. It has a smooth surface and can be written on easily.
