text: You're right, if you are skinny, I doubt you have 26% body fat as that would make you overfat.\n\nThere are a couple of online calculators I found (see below), that may give you a rought estimate, but it would be best to have it checked professionally and not by one of those hand held devices.\n\nHowever, just remember if you store all your fat in one area, such as the stomach, it may not be entirely accurate.\n\nHTH : )
