Elves are a generally tall people by human standards. While this guide is not meant to be the end-all be-all of character creation, it is however a guide of ranges. Take that in to consideration as you parse out where your character sits on the height scale. Smaller than 5'8" and larger than 7' will likely be seen as a disability of some sort.

Female elves: 5'8" - 6'8"
Male elves: 5'10" - 7"
