Measure from the center of the pedal platform to the flat shoulder of the spindle which would butt up against the outside face of the crank arm. This will only give you the "Q-factor" for the pedal. The real life Q-factor for your on-the-bike setup would be measured from the center of your pedal platform to the center of either the down tube or the seat tube.
