To start, set your saddle height from the pedal to the top, or alternatively the sit bone. I set from the pedal spindle to the top. To get the measurement, try the competitive cyclist fit calculator. Those numbers will be within a cm of what you find comfortable. Too low, and you lose power. Too high, and you will hurt your knees.
The saddle, pedals, and shoes you wear will all affect the overall fit.
