Parabolic: A parabolic kneeboard angles to a flat nose shape and tail shape. The Hydroslide Phantom Kneeboard is an example of a parabolic kneeboard.

Twin-tipped diamond-shaped: A twin-tipped diamond shaped kneeboard has a nose shape and tail shape that each angle to a point, with straight sides, so the overall appearance of these kneeboard shapes is that of an elongated diamond. The HO Sports Proton kneeboard is an example of a twin-tipped diamond-shaped kneeboard.

Squared-off: Some kneeboard shapes are more like giant rectangles, such as the HO Sports Element kneeboard, which also features hard rails that let you hold a deeper edge.
