Cruising direct, FX sails, both have online sizes for many sailboats.
Otherwise, personally, I would talk to nearest sailmaker/rep to your boat, then have it measured and go with recomendation. If you main is anything like my 85 Jeanneaus main, I can increase the size by some 20%, as it was ade a bit on the small side as far as leech, and foot measurements, and I can increase the roach a bunch too. Not sure if these performance inhancments are what you want, vs just a robust sail......again, talk to a local sailmaker for best info.
