The letters and numbers stamped near the ferrule tell you one thing: how hard or soft the graphite core is, and so how light or dark a mark it leaves. That is the whole system. The part most charts skip is that the scale isn't standardised, so one maker's 4B can sit where another's 2B does. Because we hold every grade across roughly 28 brands, we can show you that drift rather than reprint the usual single-brand diagram. Our other grade guides link back here.

What does the H and B on a pencil mean?
Two letters carry the whole hardness scale:
- H = Hard. More clay in the core, less graphite. A harder, finer point that wears slowly and leaves a light, grey line. The more H's (or the higher the number, 2H, 3H… up to 9H or 10H), the harder and lighter it gets.
- B = Black. More graphite, less clay. A softer core that lays down a darker, denser line, wears faster and smudges more readily. The higher the B number, the softer and blacker.
- F = Fine point. A firm grade that sits just on the hard side of HB and holds a sharp point well. The "F" is usually read as fine point, though "firm" is the other common gloss; manufacturers have never been fully consistent about it, so treat F simply as "a touch harder and crisper than HB".
The physics behind it is older than the lettering. In 1795 the French inventor Nicolas-Jacques Conté patented a method of grinding graphite, mixing it with clay and firing the result — and the more clay in the mix, the harder and paler the pencil. Every grade you'll ever buy is a point on that single clay-to-graphite dial. (The H/B/F letters themselves were a later European trade convention; they're widely credited to English and Bohemian makers refining Conté's process through the 1800s, but the exact origin is muddier than most charts admit, so we'll leave the attribution there rather than overstate it.)
What is the full pencil grade scale from hardest to softest?
Running from the hardest, palest grade to the softest, blackest, the standard European sequence is:
10H · 9H · 8H · 7H · 6H · 5H · 4H · 3H · 2H · H · F · HB · B · 2B · 3B · 4B · 5B · 6B · 7B · 8B · 9B · 10B · (11B · 12B)
Read it as a thermometer: hard and light on the left, soft and dark on the right, with HB and F marking the neutral middle. Not every brand makes every step — a pocket writing pencil might offer only HB and 2B, while a flagship artists' line runs the whole span. The far ends (10H, and 11B–12B) are specialist territory: only a couple of lines reach them, which is why the headline figure of "how dark can a pencil go" comes down to a handful of products rather than the scale itself. The hardest you'll routinely find is 9H or 10H; the softest mainstream grade is 12B (Staedtler's Mars Lumograph), with one off-scale outlier — see below.
Why is HB in the middle, and what sits either side?
HB is the deliberate balance point — "Hard-Black" — equal parts of the two qualities, dark enough to read clearly and hard enough to keep a point. It's the default office and exam pencil for exactly that reason. F sits immediately to its hard side (slightly crisper), then the H grades climb away into harder-and-lighter territory. To HB's soft side you cross into B, 2B and beyond — softer, darker, more expressive.
So the mental model is: everything left of HB is built for precision and faint, erasable lines; everything right of HB is built for tone, darkness and drawing. HB is the hinge.
What is each grade best used for?
Grades cluster into four working zones. This is the practical answer to "which pencil do I actually reach for":
| Zone | Grades | Best for | Watch out for |
|---|---|---|---|
| Hard / technical | 9H–2H | Drafting, technical drawing, light construction lines, tracing, faint underdrawing you'll ink over. Holds a needle point. | Too pale for finished work; presses grooves into soft paper; can scratch and shine. |
| Everyday / writing | H, F, HB, B | Handwriting, note-taking, exams and multiple-choice forms (HB is the classic "#2"), general sketching, crisp linework. | Nothing much — this is the safe, all-round band. |
| Sketching / soft | 2B–4B | Loose sketching, life drawing, expressive line, the workhorse grades for most artists' day-to-day marks. | Smudges more than HB; needs sharpening often. |
| Shading / deep darks | 5B–9B (+10B–12B) | Rich shadows, dramatic tonal range, the darkest accents in a drawing. | Wears fast, smears easily, and very soft graphite can "shine" if over-burnished. Keep a barrier sheet under your hand. |
Quick rule of thumb: writing and exams → HB; technical/drafting → 2H–4H; general drawing → 2B; shading and dark accents → 6B–9B. Most artists carry an HB, a 2B, a 4B and a 6B and rarely need more.
How does the Japanese 10H–10B scale differ from the European one?
This is where a popular misconception needs unpicking. People talk about a separate "Japanese scale", but Japan's pencil makers use the same H/F/HB/B letters as everyone else; there is no rival notation. Two things are genuinely different:
- Range. The Japanese flagships are the most finely stepped lines in the world. Mitsubishi's Hi-uni and Tombow's Mono 100 both span a full 10H to 10B — 22 grades, every integer in between, with no gaps. Most European drawing lines stop a couple of steps short at each end.
- Character per grade. The premium Japanese cores use very pure, finely milled graphite, so grade-for-grade they tend to feel smoother and lay down a touch darker than a firm European technical pencil of the same letter. A Hi-uni 2B feels creamier and reads slightly darker than a hard-wearing draughting 2B from a European maker. That is formulation, not a different scale.
So "the Japanese scale" really means a fuller, finer, generally darker and smoother take on the ordinary scale. If you have only ever used office HBs, a Japanese flagship is the cleanest way to feel what the grade numbers are meant to do. See the full Mitsubishi Hi-uni set of 22 (10H–10B) and check the price →
Which grade is the darkest you can buy?
On the published scale, the softest mainstream grade is 12B, reached by the Staedtler Mars Lumograph 100 — the highest B-number in any widely sold wood-cased graphite pencil. The Japanese flagships top out a little firmer at 10B; most other artists' lines stop at 8B or 9B.
There is one true outlier. General Pencil's Kimberly 525 includes a special, extra-soft matte-black grade marked 9XXB: not a normal scale position at all, but a purpose-built formulation that lays down denser and blacker than its number suggests. If maximum black on the page is the goal, that is the one. We go through the records in our companion guide, The Darkest Pencils You Can Actually Buy.
Worth saying plainly: even a 12B can't out-black charcoal or a dedicated carbon pencil, because graphite reflects light with a faint sheen. Soft graphite (8B–12B) is the sweet spot when you still want to erase, lift and refine — not when you want the absolute matte darkest mark possible.
The catch nobody prints: grades aren't standardised
There is no enforced international standard fixing how dark a "4B" must be. Each manufacturer grades against its own line, so the same letter genuinely shifts between brands. In practice that means a soft Japanese 2B can read as dark as a firm European 3B–4B, and a hard technical H can sit crisper and paler than another brand's H. If you're matching a value in a drawing, trust your eyes on the paper, not the stamp.
What we can give you honestly today is the hard part: the actual grade span each major line offers, side by side. Holding every grade across our catalogue, we can table the real ranges rather than guess:
| Line | Hardest | Softest | Grades | Origin | Character (grade-for-grade) |
|---|---|---|---|---|---|
| Mitsubishi Hi-uni | 10H | 10B | 22 | Japan | The benchmark: smooth, creamy, runs slightly darker than European equivalents. The finest-stepped line we stock. |
| Staedtler Mars Lumograph 100 | 10H | 12B | 24 | Germany | Break-resistant, consistent, firmer feel; holds the record for the highest B-number (12B). The widest published span here. |
| Faber-Castell Castell 9000 | 6H | 8B | 16 | Germany | The classic European drawing pencil — controlled, fairly firm, dependable rather than dramatic. |
| Derwent Graphic | 9H | 9B | 20 | UK (Cumberland) | A broad, even, affordable British range; softer grades are a touch grittier than the Japanese flagships but great value. |
| General's Kimberly 525 | 9H | 9XXB* | 21 | USA | American workhorse with a notably matte feel; the off-scale 9XXB goes blacker than the numbered scale allows. |
*9XXB is a special extra-soft formulation, not a normal scale position. General count it as the softest of the line's 21 published degrees (9H to 9XXB).
So the practical advice is simple: buy a range, then learn that range. Once you know how your line steps, the letters become reliable shorthand within that brand. Across brands, treat them as a guide, not a guarantee.

FAQ
What does HB mean on a pencil?
HB stands for "Hard-Black" — the balanced middle grade, dark enough to read and hard enough to hold a point. It's the standard writing and exam pencil, and in the US numbering system it's the same as a #2.
Which is darker, a higher H or a higher B?
B grades are the dark ones, and the higher the B number the darker and softer the line (9B is far darker than 2B). H grades go the other way: higher H means harder and lighter. So 6B is dark; 6H is pale.
Is a #2 pencil the same as HB?
Effectively yes. The American numeric system maps #2 ≈ HB and #2½ ≈ F. It's the same hardness, just a different label, which is why exam instructions that ask for a "#2 pencil" are satisfied by an HB.
What grade should I use for shading?
For general shading reach for 2B–4B; for the deepest shadows and final accents, 6B–9B. Keep your hard grades (H and up) for technical lines and faint underdrawing, not tone.
Why does my 4B look darker than my friend's 4B?
Because pencil grades aren't standardised between brands. Each maker grades against its own line, so a soft Japanese 4B can read darker than a firm European 4B. Match values by eye on the paper rather than trusting the stamp across brands.
What's the darkest pencil grade you can buy?
12B (Staedtler Mars Lumograph) is the darkest grade on the standard scale. General's Kimberly 525 9XXB is a special off-scale formulation that goes blacker still. Neither beats charcoal for sheer matte darkness, but both erase and refine in a way charcoal can't.
Sources & method: grade ranges are taken from each manufacturer's published grade charts (Staedtler, Faber-Castell, Mitsubishi/uni, Derwent, General Pencil) and cross-checked against our own catalogue of graphite pencils spanning roughly 28 brands. The hardness mechanism dates to Nicolas-Jacques Conté's 1795 graphite-and-clay process. Darkness "character" notes are our own bench impressions; measured, photographed cross-brand darkness swatches are a separate project — where we couldn't verify an exact equivalence we've said so rather than invent a figure.
