A simple tape measure will let you determine the rise of your handlebars. There is total rise, and end rise. Total rise is the measurement from where the handlebars clamp in your risers, or mount to your top triple clamp, to the highest vertical point of the handlebars. End rise is the measurement from the handlebar clamping area to the center of the end of the tubing in the hand grip location. For accuracy, be sure to measure straight up to get this measurement, and not at an angle from the clamping surface.
