Paddles with blades included historically measured over 200 cm, but now usually measure between 185 and 205 cm. Also the industry has begun to offer bent shafts that are ergonomically shaped to relieve stress off of the paddlers wrists. Many companies also offer specialized rubber grips to ease the paddlers grip and provide a place to feel where hands should hold the shaft. Small and regular shaft thicknesses may be available as well to offer smaller paddlers more comfort while gripping the paddle.
