You need a set of calibrated calipers to do this. You measure a fold of skin from several areas, I can't remember where or how to translate the measurements. Only trouble is that it doesn't really work if you are significantly over-weight. The only truly accurate measurement is a volume displacement test where they dunk you in a water tank and see how much volume you displace.
The calipers can be found in health or fitness stores sometimes or online.
