The solution, in part, is to have the actual part in front of you to check that the measurement you are reading is actually the measurement you think you are getting.

Then check the pads/holes with the actual part and see how it matches.In addition to this, I mount the print out on a piece of 1/4" foam craft board with sticky backing. For pin and hole parts, I poke a hole through the foam board and place the part in the holes. This way, you can also check for interference between parts. Even doing all this, I still get surprised every once in a while.
