You probably remember needing one of these for Scantron tests. This is because anything harder than a 2 pencil was too light for the machine to read and the 1 pencils often smudged. Drawing pencils typically use the HB system. H pencils indicate a hard lead while B pencils indicate the blackness or softness of the lead. You may also come across an F pencil which means that the pencil sharpens to a fine point.

Be aware that not all manufacturers are the same. A 2 or HB pencil from one manufacturer may not leave the same mark as a 2 or HB pencil from another. When it comes down to it, choosing the hardness of lead is left up to personal preference. Some like a darker line while others like a delicate, light line. If you are still unsure, a 2 or HB pencil should work fine for your needs in the office. You want to have at least one soft and one hard pencil along with an HB.

At this point in time, the F pencil is the only grade that isn't accompanied by a number because there's only the one variant. The F is equivalent to an H, but with the added feature of staying sharp longer. Because they so rarely require sharpening, one F pencil can last an entire drawing career!

The higher the number, the harder the lead and the lighter the mark left on the paper.

As the pencil core becomes softer through the use of lower proportions of clay it leaves a darker mark as it deposits more graphite material on the paper.
