I'm submitting my assignment and get error from the automated format checker.

First of all, I use:


Error: Leading too small: minimum 12pt, saw values as small as 11.9pt

Why do you think this problems occur? Can I force if it happens for some reason?

Unless there is something strange going on in the remainder of your preamble, the automated format checker is just wrong: With those options, latex will set \baselineskip=12pt so either some latex package is later overriding this, or the format checker has a bug.

  • You can try adding \showthe\baselineskip somewhere in your document to check whether that length is indeed 12pt. If it is, you may want to increase it slightly to make the format checker happy. Commented Apr 25, 2011 at 11:49
  • I guess perhaps the checker might be using "postscript points" (1/72 in) instead of traditional points (1/72.27 in). Although 12pt == 11.96bp, so still not as small as 11.9 after rounding. Maybe setting \baselineskip=12bp will satisfy the checker.

  • @Bruno Le Floch, @Lev Bishop, after compiling couple of times, the checker stop warning me. Thanks for your answers.
