Paddleboard size by weight

Volume carries a paddler; length and width make the board stable or quick. iRocker sizes volume from body weight in kilograms, Alpkit from total weight in pounds, and the two rules do not quite agree, so each page shows both.

Board ratings come in two kinds: Red Paddle Co and Alpkit state a rider maximum in kilograms, ISLE a beginner capacity in pounds. iRocker's advice to stay 10 to 15% under the stated maximum is applied to all of them. Size a board with your own profile
