Having the right size surfboard is an essential factor to maximize your time and effort in the surf. The surfboard calculator featured below allows you to calculate the size of your board by knowing the stock dimensions only.

# Surfboard Volume Calculator

### 45.9 LITERS

Surfboard Volume = The space surfboard occupies In Liters

**VOLUME = BUOYANCY = SIZE**

Although, what many beginner surfers don’t know, is that it’s not ultimately the VOLUME, but also the TYPE of surfboard that plays a huge role in your performance.

Finding the suitable surfboard **volume** according to your** skill level** and **types of waves** are the most important factor when choosing a surfboard!

### How To Choose The Right Size Surfboard?

**Type of waves.**

*Are the waves small and slow, or fast and hollow? Point, or beach break? Do you need a fish/hybrid for small and slow or a shortboard for fast and hollow waves?***Skill level.**

*Are you a beginner, intermediate, or advanced surfer? Check the volume recommendation chart above to find the most suitable range for you***Riding style.**

*Do you want a sporty shortboard for sharp turns or a cruisy longboard?*

**How To Choose a Surfboard?**

**TYPE**of surfboard – A shortboard, fish, hybrid, or a longboard? Epoxy or fiberglass?**VOLUME**– Get a board with the right amount of volume.**SIZE**– Lastly, once the type and volume are fine, choose a suitable size.

## Surfboard Volume Size Calculator – How It Works?

*How to manually find the Surfboard Volume by knowing the stock dimensions only?*

*STEP 1 – Convert* the surfboard sizes from feet and inches to centimeters ( x’y” to cm)

*STEP 2 – Multiply*:

**L**ength

**x**

**W**idth

**x**

**H**eight ( L x W x H )

*STEP 3* – **Get** **54%** to **58%** out of the sum by multiplying the result with **0.54** or **0.58 **(515151 x 0,54)

### Symbolistics:

**1** feet = **1‘** = **30,5 **centimers = **30,5** cm

**1** inch = **1“** = **2,5 **centimeters = **2,5** cm

**1 **feet **1** inch = **1‘1“** = **33 **centimeters = **33** cm

To know how much volume does the surfboard occupy, you need to do some simple calculations. We have converted the most used surfboard dimensions * down below *to make things easier.

### STEP 1:

### Convert Surfboard Dimension from *imperial* to *metric*

First, to calculate the volume, you need to convert the surfboard size from feet and inches to centimeters.

*So, how to calculate the surfboard volume to liters by just knowing the stock dimensions?*

The * length*,

*and*

**width,****on surfboards are measured in**

*height***feet**and

**inches**(

**Imperial**)

The surfboard volume is calculated in liters (

**Liters Is Metrical**)

**From Imperial 6‘0 x 20“** **x 2 1/2“**

**To metric** **182,8cm** **x** **50,8cm x** **6,3cm**

### STEP 2:

Multiply the sizes

*Once you have multiplied the dimensions, you get a rough 5-digit answer. Round it down to xx,x L*

**182,8 x 50,8 x 6,3 = 58503,3**

### STEP 3:

Get 54–58% out of the sum ( x 0.54 / x 0.56 / x 0.58)

Surfboard typically occupies approximately 54-58 percent out of the perfect cube.

54% – narrow surfboard

56% – average size surfboard

58% – round shaped surfboard

**58503,3 x 0,54 = 31591 ≈ 31,5Liters**

Here’s Why You **Shouldn’t Hire** a Surfer

### Published by:

I created Nulltuul to share my experience, research and analysis with other surf enthusiasts out there. If I'm not surfing on my travels - I like to photograph waves, surfers, and the surf lifestyle in general.

NicoHi !

the calculator is great ! I use it all the time, thanks for making it available.

I have a couple of suggestions to make it even better:

– could you add more options in the width and thickness please? Many boards come up with widths like 18 5/8 or thickness like 2 5/16

– this one might be harder, but could we have an option for a more precise adjustment bar, so we can match dimensions from a website? I’ll explain that second one:

Say for example I have a board which is not stock dimensions. The Shaper’s website might list stock dimensions like 6’0 x 19 x 2 1/2 and 30.5 litres, but the board I have (custom) is 6’0 x 18 3/4 x 2 7/16.

If I enter these stock dimensions in your calculator, it gives me 30L for a shortboard or 31.1 for a fish. We could have the option to change the multiplier by sliding a bar, until the stock board is displayed as 30.5 litres. Then, with that multiplier set, we could enter the custom board dimensions (6’0 x 18 3/4 x 2 7/16) and have a good guess of the volume of the custom board.

I hope it makes sense

EJHi Nico

Thank you for your suggestion, I’ll make it happen soon! Stay tuned

Orson b marksAnd how about making more lengths for longboards.

Ermo JoelehtDone, thanks for noting.

PanxoEsto es espectacular

CoreyHey EJ this is super cool! I’m messing around trying to program my own surfboard calculator tool as a cool little portfolio project in JS and React. May I ask how you calculated the algorithm between the different skill levels? Rad stuff you got here.

-Corey

EJHi Corey

Thanks for reaching out. I pretty much copied the skill level/volume recommendation by many charts online, and simply rounded to get the average of about five different recommendations. Good luck with your calculators & portfolio!

CoreySweet, cheers dude

MikeBravo! Your calculator is brilliant. I’ve been interested in volume for many years, and I was so pleased to see that it has become a standard measurement since the widespread use of CAD for board design. Of course I have some surfboards that were hand shaped or otherwise don’t have the volume stated, and your calculator works great for estimation. as an engineer and a passionate surfer, I really appreciate this tool!

GaryGnuuFinally math I understand!

Simey LamezeHey there, nice tool! I used it all the time!

Wondering if you could add 2 1/8 and 2 9/16 to the list of thickness? Many surboard models use these fractions.

Cheers

LUCAS MACHADO SENAGreat Tool. Just remind, for small/weak waves more volume, better/powerful waves less volume.

CautionIt is helping us mostly for the shapers and thank you so much for this link.
