Find out Why The Graphite Pencil Scale has 24 Degrees of Hardness, What are H & B Grades & How This Relates to The U.S Pencil Hardness Scale.
There are two graphite grading scales used to measure the hardness of a pencil’s graphite core. NUMERICAL GRAPHITE SCALE. The first graphite grading scale is a numeric scale. Using this scale, the hardness of the core is often marked on the pencil — look for a number (such as “2” “2-1/2” or “3”).
The scale ranges from 9H to 9B, which is from the hardest to softest or blackness of a pencil. The designated letters come from hardness and blackness. In the middle, you have the HB (Hard Black) and F (Firm) pencils, which have medium pencil hardness.
Here’s an explanation of pencil grades and how to choose the right hardness: 1. H Grades (Hard): H grades, such as 2H, H, and 3H, have harder graphite cores. These pencils produce light, fine lines with minimal smudging. They are ideal for technical drawings, drafting, and tasks requiring precision and fine details.
The 19 degrees of graphite pencil hardness are: 14B, 12B, 10B, 8B, 7B, 6B, 5B, 4B, 3B, 2B, B, HB, F, H, 2H, 3H, 4H, 5H, and 6H. Graphite pencils with hardness degrees of 3B to 8B are ideal for artistic, pictorial drawing with their very soft to extra soft, very black graphite.

If you’re an artist or an aspiring one, understanding the graphite pencil scale is essential. This comprehensive guide will walk you through everything you need to know about the pencil darkness scale, drawing pencils scale, pencil grading chart, and graphite value scale.
The HB Graphite Scale – Pencil manufacturers use letters to indicate the various degrees of hardness of the lead in a pencil. The letter “H” is used to indicate a hard pencil. “B” is used to indicate the blackness of a pencil, and “F” indicates that a pencil is firm and sharpens to a fine point.
