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.
Most types of board are available in 9.5 or 12.5mm (3/8 or 1/2 inch) thicknesses, the thicker size is most often used and has increased rigidity. The usual sheet size is 0.9 or 1.2 m (3 or 4 ft) wide and length vary from 1.8 to 3.6 m (6 to 12 ft) long but other sizes may be available-often just cut down sheets.Most plasterboards come with a white paper face and the other side a grey, thicker paper face.he usual sheet size is 0.9 or 1.2 m (3 or 4 ft) wide and length vary from 1.8 to 3.6 m (6 to 12 ft) long but other sizes may be available-often just cut down sheets.
