Stapling paper

When stapling a bunch of letter or a4 sized sheets, staple sizes can be chosen using the following table.

Number of sheets    Stack height      Staple size
   25                  1/8''             1/4''
   60                  1/4''             3/8''
   90                  5/16''            1/2''
  160                  9/16''            3/4''

I assumed the thickness of paper is roughly around 0.1 mm (which might not always be correct!).
