I use 16 inch wood and I have a 20 inch bar. I made a mark with Majic marker 16 inches from the tip of the bar, a big black mark right across the bar. I just lay the bar on the log, at the mark, and I see where the end of the bar is and start sawing. I don't actually mark the log. I wind up with pieces from 15 1/2 to 16 1/2. It doesn't have to be exact.
