What does HB pencil refer to in terms of hardness?

The term "HB pencil" refers to a specific grading of pencil lead that signifies a medium hardness and darkness. The "H" denotes "hard," while the "B" indicates "black." An HB pencil strikes a balance between these two characteristics, making it versatile for various drawing and writing tasks. It produces a mark that is neither too light nor too dark, providing a reliable option for artists and students alike.

In pencil grading, "H" pencils are harder and produce lighter marks, whereas "B" pencils are softer and yield darker marks. The "HB" designation is strategically positioned in the middle of the hardness scale, allowing it to cater to a wide range of needs without leaning too far toward the extremes of either soft or hard leads.
