Surfboard sizes shouldn't be determined by age, but rather, their height, size, and experience. For example, if you're a beginner, you might want to look into a long board. Usually, you would get a long board 3 feet longer than your own height. A funboard should be a foot or two taller than your height. A fish board should be just under 1 foot and a shortboard should be about 3-6 inches taller than your height.
