Reply	Jon-Richfield says: This is not consistent. Soft pencils generally leave thicker lines than harder, but even within a single line, thickness varies by a few orders of magnitude. I should reckon something between one and ten micrometres would be a reasonable thickness, but you would have a hard time proving it on any one line.  (no votes) Tags: materials.

Reply	Georg says: When You look at a paper surface with the aid of an microscope, You will see that the question for "thickness" is not making sense. Soft pencils will fill up the voids in the paper "landscape", hard ones will leave discolored stains on the "mountain" tops. Georg  (no votes) Tags: materials.
