Don’t ever submit a screenplay less than 100 pages or more than 140 pages in length. And don’t cheat by using wide margins or changing font size. Screenplays are printed in Courier or Courier New fonts, size 12. Place one-inch margins top, right, and bottom. Place one- to two-inch margins on the left. The average film script runs 110 to 120 pages, which translates, almost without exception, into a minute of film per page of script. You can’t fool us.
