Windsurfing Boards & Windsurfing Sails – What Size?

Following up on my last post giving a buyers guide to choosing windsurfing equipment I came across a very useful tool for figuring out what windsurfing board, windsurfing sail & fin size you should have.

Whether you are just moving on from the learn to windsurf stages and trying to decide what your first windsurfing board should be or you are a seasoned pro trying to fill a gap in your windsurfing sails quiver, this interactive spreadsheet guide to choosing the right windsurfing boards, fins & windsurfing sails is really useful.

Windsurfing Boards
Fire up the spreadsheet in Excel, choose the ‘Board Size’ tab & enter your weight in KG or lbs.
The program tells you:

  • Minimum size beginners board you should be using
  • Ideal first short board
  • Smallest size windsurf board that can be uphauled
  • Windsurfing Boards size Guide

    Know what size windsurfing boards you should have

    Windsurfing Sails
    Move across to the Windsurfing Sail Size tab, enter your wegith in KG or lbs.
    The program displays:

  • Two lists showing different wind strengths & what size sail you should be using
  • A separate list showing wind strength & sail size for a beginner
  • A graph showing ideal sail size v’s wind speed
  • Windsurfing sails size guide

    Finding exactly the right size sail for a given wind strength

    Windsurfing Fins
    Move to the last ‘Fin Size’ tab, enter your weight in KG or lbs & sail size in sq metres.
    The program calculates the recommended fin size for you:

  • Fin size for – underpowered, ideal wind & over powered conditions
  • Adjusted sizes for – freeride, slalom, wave, formula & even sailing where there is weed!
  • Windsurfing fins size guide

    Know the right size windsurfing fin for any sail size

    Having checked through a few examples myself the calculations are pretty accurate to the real world. All credit to James Douglass who developed this number crunching monster. If you want your own copy of this great guide click the following link Ultimate Windsurfing Equipment Size Calculator

    With all that data at your finger tips you should never be stuck trying to figure out what windsurfing kit you should be buying or sailing on!

    1. That’s really cool! …….. I’ll collate each sail size to the wind strength so I don’t have to dither and procrastinate. So simple. Great stuff.

    2. Glad to help. As you say, its so simple to get instant feedback on everything relating to sizing your windsurfing boards, windsurfing sails & fins. No more guess work.

    3. I usually don’t post on Blogs but ya forced me to, great info.. excellent! … I’ll add a backlink and bookmark your site.

    4. Thanks for the comment, its always good to here that people really appreciate the Top Windsurfing Tips & News that we provide.

    5. What’s the url to get this excell file??


    6. Sorry… I meant to say that I need the FIN size calculator as it is not in the excel link…


    7. wow… I’m a moron!

      If you look at the bottom of the file there are tabs for baord and fin sizes!

    8. Hey Chris, glad you figured out how to get to the fin size calculator. As you say, the info is split over different excel page tabs.
      There is tons of info provided in this little windsurf board, sail & fin size calculation system – enjoy!

    9. Wow… quite amazing really. Thanks and well done.

    10. Nice work!! For racing and speed I think the used sail sizes are about 20% bigger

    11. Taking the plunge after 15 years of hiring and in the process of buying lots of second hand kit, rigs, fins, etc…. off ebay and that.
      Lots of head scratching from all the possible variations and then you come along… fabbo!
      James – this is well handy.
      Mouchos Gracias

    12. Glad to help, choosing the right windsurfing equipment can be a challenge at the best of times not to mention when negotiating the maze of the second hand kit market.

    13. A question about the software. When you use it against today’s boards it seems out of sync : basically all board recommendations are 15-20cm longer than what you would find om the market today where boards are classified more by width/volume. Perhaps the excel spreadsheet needs a little upgrade??

    14. You could be on to something there, I will check it out. Board lengths have been getting shorter by the year & it would be good to get the formula working to account for width & volume.

    15. Bonjour,

      J’habite Goma à l’Est de la RDCongo, j’aimerai avoir le prix de la planche uniquement(le moins couteux et savoir s’il est possible de le faire livré?

      Bien à vous

    16. Hi, we specialise in windsurfing lessons & windsurf rental. We do not sell windsurfing equipment but rather offer free independent advice, such as in this article, to anyone who wants help in choosing the right kit. There are several good online windsurfing shops that deliver outside of the UK. Just type in the name of the windsurf board you are looking to buy into a Google search and it will bring up such online retail shops. Hope that helps you out.

    17. One problem 1kg ~ 2.2 lbs not 1 lbs ~ 2.2kg

    18. Seems a bit on the small/low side, but def a cool guide.

    19. Lukasz – Sorry for the delay in replying but yes you are absolutely correct. Luckily the actual formula is the right way round and it was just the explanatory note that stated the conversion the wrong way round! I have now corrected the wording to avoid any confusion. Thanks for the heads up.
