A lot of people ask us if a certain size bag will be too big or too small on them, so we're always looking for ways to help you find the right bag size for you.
I've dedicated a flickr set to photos of Timbuk2 employees (of various sizes) rocking our bags (of various sizes) and will be adding to it regularly. Hopefully you'll find someone here who is shaped more or less like you and maybe it will help you decide the right size bag for you. Good luck and let us know if you don't see your favorite bag paired with the right-sized T2 employee, we'll try to accomodate.
