Calculator/Surfboard types

Surfboard types

Seven families cover 95 per cent of what gets surfed: softboard, mid-length, fish, hybrid, shortboard, gun and longboard. Which one is yours follows from your level and the waves at your spot, and only then from the dimensions.

Each family exists to solve a different problem, and pushing it outside its dimension range turns it into something else. Choosing the right type matters more than fine-tuning half an inch inside the right type.

Which one is yours

Ranges for each type

Real ranges for each board type
Board Length Width Thickness Fill
Softboard 7'0" – 8'6" 24 % 2¾" – 3¾" 0.60
Mid-length 6'6" – 8'0" 26 % 2⅛" – 3⅜" 0.59
Fish 5'4" – 6'8" 30 % 2⅛" – 3" 0.53
Hybrid 5'6" – 6'5" 28 % 2⅛" – 2⅞" 0.57
Shortboard 5'6" – 7'0" 27 % 1¾" – 2⅞" 0.55
Longboard 8'6" – 10'0" 21 % 2½" – 3½" 0.61
Gun 7'0" – 9'6" 22 % 2⅜" – 3⅜" 0.52

Width is expressed as a percentage of length. The fill factor is the fraction of the length × width × thickness box the board actually occupies: a fish fills 0.53 and a longboard 0.61, which is why two boards of the same length can float completely differently.
