Enter the length (in), the width (in), and the thickness (in) into the Surfboard Volume Calculator. The calculator will evaluate and display the Surfboard Volume. 

Surfboard Volume Formula

The following formula is used to calculate the Surfboard Volume. 


  • Where SV is the Surfboard Volume (in^3)
  • L is the length (in) 
  • W is the width (in) 
  • T is the thickness (in) 
  • SF is the shape factor
    • Typically between .45 and .65 depending on the shape

How to Calculate Surfboard Volume?

The following example problems outline how to calculate Surfboard Volume.

Example Problem #1

  1. First, determine the length (in). The length (in) is given as 40.
  2. Next, determine the width (in). The width (in) is calculated as 12.
  3. Next, determine the thickness (in). The thickness (in) is found to be 5.
  4. Next, determine the shape factor. This is provided as .55.
  5. Finally, calculate the Surfboard Volume using the formula above: 


Inserting the values from above yields: 

SV = 40*12*5*.55 = 1320 (in^3)

Example Problem #2

The variables needed for this problem are provided below:

length (in) = 50

width (in) = 15

thickness (in) = 3

shape factor = .45

Entering these values and solving gives:

SV = L*W*T*SF =1012.5 (in^3)
