    That’s why decent rulers have a 0 and a margin:

      It really depends on what you’re measuring. Good luck measuring the distance from a corner if you can’t get 0 to touch the end.

      Tape measures are almost always designed with this in mind, so you can hook the end over an edge, or butt it up against something and the measurement will be accurate both ways, since the metal end can slide in or out by just the right amount.
