Drawing pencils are labeled by hardness and softness.
For example - 6H is the hardest (makes the lightest mark), then 4H is a little less hard (makes a slightly darker mark), 2H,etc.
HB is in the middle
The it goes 2B, 4B, 6B, etc. - the higher number in the B's, the softer it is and the darker the mark it will make.
6B is the darkest.
I've never heard of an 'HB #2' pencil. I'm saying that no one makes them! But this is what I know about pencils. 'H' pencils are typically used for graphic drawings. The lead is harder and the lines tend to be lighter and thinner. The lead is less prone to smearing. The higher the number, the lighter and harder the lead. Then we have the 'B' pencils. The lead is softer, darker, the lines tend to be thicker. As the number gets higher, these qualities increase. A 6B pencil gives a very dark, thick line. These pencils are used more commonly for sketching in the typical 'drawing', like an artist's picture. These leads smear on paper easily! As an architectural student, I'm required to use an 'HB' pencil. This is just a blend of H and B leads. It still has an annoying habit of smearing on vellum! I usually stick to H2 pencils and higher whenever possible to keep my work clean!
Each graphite pencil, the 6H, 6B, 2H and 2B, will create a sharp line and fine detail. The difference is that the softer leads (2B, for example) will need to be sharpened more often to keep drawing this detailed. That is because, while having a sharp point when freshly sharpened, the softer the lead, the more quickly it will wear/crumble down.
6B is the darkest.
2B or not 2B, that is the question.
2B 2B or not 2B, that is the question.
The order of hardness goes:9H 8H 7H 6H 5H 4H 3H 2H H F HB B 2B 3B 4B 5B 6B 7B 8B 9B hard medium soft
It is a pencil gradation system. HB means hard black B means black and 2H means harder.H (2H, 4H, etc) are the harder leads, and therefore draw a lighter line; and B (2B, 4B, etc) are the softer leads, and therefore draw a darker line. HB is the very middle. The larger the number, the farther away from HB it is. So for instance, 6B will be darker than 2B, and 4H would be lighter than 2H.Read more: What_do_HB_B_2H_signs_in_pencils_mean
Pencils are sorted into how hard and how soft the graphite is. The scale ranges from 9H (hardest) to 9B (softest). Number 6B would mean its graphite is 4th softest.
H stands for hardness and B stands for blackness this is how a pencil scale goes: 9H 8H 7H 6H 5H 4H 3H 2H 1H H HB B 1B 2B 3B 4B 5B 6B 7B 8B 9B9H is very fine hard and light but 9B is thick black and very soft (more like charcoal)
A #2 graphite pencil made of wood weighs between 6 and 10 grams. The difference is in the thickness of the wood (cheaper pencils have thinner wood). But it depends on the pencil. There are many different types of pencils that are mainly used in art. There's an HB pencil which is just a regular office pencil, which is probably what you're measuring. But there are also others. There are 2B, 4B, 6B, 8B, and 9B. The higher the number, the darker the color of the lead and the softer the lead. So even though 9B is the darkest color, you'd think it would be the heaviest, but really HB is.
If you want. Pencils with higher numbers such as 6Bs give a darker stroke and are softer. So, if you don't mind using a harder, slightly lighter pencil, then go ahead.
The 'h' and 'b' rating combined with a number refer to the hardness of the graphite in a pencil. h-hard and b-soft. So the higher the number the more hard or soft it is. Hard graphite imparts much lighter marks to paper, while softer graphite makes a much darker mark. So a 6b pencil is very soft and draws quite dark while a 6h pencil is very hard and draws very light marks.
That would depend if the pencil were an H or a B. Artist pencils are identified with a number and a letter. H is for hard. A 6H pencil would be harder than a 4H pencil. B is for soft. A 6B pencil would be softer than a 4B pencil.
