Aiming headlights

I just upgraded my headlights for better viewing at night. My old headlights were way out of adjustment to shine on the road and what Im looking for is the way to properly adjust my headlights. I adjusted them the best I could to be focused on the road.

What Im trying to find out is, whats the distance from the wall to the front of the car, and what should the measurement be from the ground to the headlight pattern on the wall be?

Thanks in advance with my problem
