Simply put, for all-round paddling, the paddle should be about 10-20 cm longer than you. When paddling in waves, most people use a much shorter paddle, and skilled distance paddlers often use a slightly longer paddle. But everything is personal and depends on paddling technique. The shape, material and size of the blade also have a big impact. Today, it is common to use a large blade for paddling in waves, where It usually takes a couple of big strokes to get going. Smaller blades are most often used by distance paddlers on flat water where they strive for a high frequency and short strokes. Factors that influence the choice of paddle are technique, area of use and the person's weight and physique.
