For people 5'10" and over, the best barometer is the old Height-Weight proportionate scale.

Not sure just what that is, but if it's the old "insurance company" based tables, it's even worse. The very best is to have your % body fat measure directly, that is by measuring your density. This involves weighing you under water (full immersion) as well as normally. Fat is less dense than mussle or bone. In my case that would probably show me as less fat that I really am, because my extra dense bone structure would offset some of the fat.

You mentioned bone structure, that was what the article said was the main reason that the BMI gradually runs amiss as people get taller.

Also the article did say that the best test for body fat was the water immersion test.
