Tips & Common Mistakes

Tips

  • Remember that 1 pica = 4.2333 mm, so multiply the number of picas by 4.2333 to get millimeters.
  • For quick estimates, you can round to 4.23 mm per pica, but for precise print work use the exact value.
  • Double-check your input: ensure you are entering picas, not points (1 pica = 12 points).
  • Use this converter when switching between software that uses picas and specifications that require millimeters.

Common Mistakes to Avoid

  • Confusing picas with points: 1 pica = 12 points, so entering points as picas will give incorrect results.
  • Using a rounded conversion factor like 4.2 mm instead of the exact 4.2333 mm, which can cause small errors in precise layouts.
  • Forgetting that this converter is for PostScript picas, not traditional typographic picas that may have slightly different values.
