At 110 kg an intermediate shortboarder sits around 53 liters, a fish about 58, a midlength about 74 and a longboard about 92. Volume is the number every brand now prints on its boards: the liters of foam, which set how easily a board paddles and floats. These tables come from SurfCalc's own model, fitted to the published guides of major brands, for an average adult: 30 to 39, average fitness, surfing weekly in average waves. The calculator adjusts for your age, fitness, how often you surf, wave power and size, wetsuit and construction, and gives a ±5 % range to shop with.
