The inside of the door on my fridge is separated into 2 halves so you can't put one in the center. I put the first tap handle in the center of one half of the fridge door, so if you're looking at the front, its 3/4 across. I put the next tap handle to the left of it, spaced on an interval where I can eventually fit up to 6 taps, evenly spaced. Not that I ever will, but setting the second one dictates even spacing for all the rest.
