This chart and how-to guide from D'Addario will help determine the string length you'll need:http://www.daddario.com/DADFaqAnswer.aspx?ID=762
UNfortunately I took info from another forum and ran with it and there is a small section of string at the nut that is wrapped that extends about 2/3 of an inch over the fingerboard. Doesn't seem to effect playing (especially since I am just learning and suck anyways!). The measurement as instructed on the chart I was referred to came up at 33 inches.
