There’s no exact science to matching a board to your size & weight & there are exceptions to the rule, but as a rule of thumb – then if you’re under 6′ & below 85kg then you should go for a 10'4" or 10’8″. If you’re over 6′ & 85kg – then a 12" is usually ideal. If you want even more length & width, then the 15′ tandem works perfectly as a solo option, as well as taking tandem. The simpliest way to find out which size is best for you is by visting our size matters page that is filled with useful hints and tips.
