Middle of BB/crankbolt up the ST to the top of the saddle
Middle of BB/crankbolt in a straight line to the middle of the handlebars/stem
Front/nose of saddle to the middle of the handlebars/stem
After that you can fine tune it by moving the saddle back or forward if you need to. It works for me.
Seypat, I do something similar but, because my crankarms are different lengths I measure:
Center of pedal to top of saddle.
KOP fit.
Front tip of saddle to center of handlebars.
Using this method because one of mine is one size smaller I had to use a longer stem and max out post height.
