Surfboard Volume = The space surfboard occupies In Liters
VOLUME = BUOYANCY = SIZE
Although, what many beginner surfers don’t know is that it isn’t ultimately the VOLUME, but 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 is 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: Length x Width x Height ( 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, width, and height on surfboards are measured in 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

x0.56 (Average size hybrid surfboard)
x0,58 (round-shaped surfboard)

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.
Hi !
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
Hi Nico
Thank you for your suggestion, I’ll make it happen soon! Stay tuned
And how about making more lengths for longboards.
Done, thanks for noting.
Esto es espectacular
Hey 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.

Hi 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!
Sweet, cheers dude
Bravo! 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!
Finally math I understand!
Hey 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
Great Tool. Just remind, for small/weak waves more volume, better/powerful waves less volume.
It is helping us mostly for the shapers and thank you so much for this link.
This is an awesome tool. Can we have an option for Waveski’s as well?
It’s a tough nut to crack but I’ll try to find a way!
Excellent thanks!
This is great – thanks so much.
Thanks, perfect
As some shapers write dims using decimals and not fractions, maybe you can just add the corresponding decimal in the chart. Es: 1/4 (0.25)
Would be a extra 😉
I am searching for the guidelines to find out how much does a liter weigh in grams? 175 pounds at a 28-29 surfboard liters is suggested for a purchased surfboard. I am looking to build a surfboard to match the request from a surfer.
