Ideally, for measuring the length of a hex bolts, it depends entirely on the dimensional parameters. Hence, determining length of the bolt becomes very easy. There are industries that even demand for ways of measurements.

For measuring length, start measuring it from the tip or bottom of the bolt to the point where the head meets the shank.
