Shortboard Size Calculator

Enter your weight and height, your surfing level and the waves you surf most. The calculator works out the shortboard volume in litres from a skill factor, a range to try and a board length.

Small, weak waves need a little more volume. Big, powerful waves need a little less.

On a shortboard, volume matters more than length. Multiply your weight by a skill factor: about 0.40 litres per kg for an intermediate. A 75 kg intermediate needs about 30 litres. For a 178 cm surfer, boards of about 5'8" to 6'0" suit.

A fish or hybrid of the same volume is shorter and wider, and easier in small waves.

Volume, for paddling and catching waves.

How long should a shortboard be?

Usually within a couple of inches of your height.

What if my shortboard is too small?

You will sink, paddle slowly and catch fewer waves.

Do beginners ride shortboards?

Most start on longer boards and step down later.
