If you have ever bought a pack of pencils labelled #2 and wondered why nothing in a British shop carries that number, here is the short version: a US #2 pencil and a UK/European HB are, for almost every practical purpose, the same pencil. They are just graded on two different scales that grew up on opposite sides of the Atlantic. Below is exactly how the two systems line up, why the wording on exam papers asks for one or the other, and which HB pencils you can actually buy here in the UK.
What is a #2 pencil?
A #2 pencil is the medium, general-purpose grade on the American numbered scale, which runs (most commonly) from #1 through to #4, with a #2½ sitting between #2 and #3. The number describes the graphite core: the lower the number, the softer and darker the line; the higher the number, the harder and fainter it is, and the longer the point holds.
So a #1 lays down a soft, dark mark that smudges easily; a #4 is hard, pale and scratchy but keeps a needle point. The #2 is the deliberate middle: dark enough to read and photograph, hard enough not to smear across the side of your hand. That balance is why it became the default school and office pencil across North America, and why it is the grade printed on the side of the classic yellow pencil most Americans picture when they hear the word "pencil".
The numbered scale is usually traced back to the New England pencil makers of the early 19th century, and is often credited to John Thoreau & Company — the family firm of the writer Henry David Thoreau, who is said to have sorted graphite into numbered grades by hardness. Treat that as the commonly repeated origin story rather than settled history; what is not in doubt is that the 1–4 numbering became the American convention while the letter scale took hold in Europe.
Is a #2 pencil the same as HB?
Yes — near enough that you can treat them as interchangeable, with one real caveat we will come to.
The UK and the rest of Europe use the letter (graphite) scale: H for hardness, B for blackness, and F for a fine, firm point. Numbers in front of the letter turn the dial up — 2B is darker and softer than B; 2H is harder and paler than H. HB is the centre of that scale, balanced exactly where the American #2 sits. The two scales map onto each other like this:
| US number | UK / European letter | Character |
|---|---|---|
| #1 | B | Soft, dark, smudges — sketching, kids' writing |
| #2 | HB | The everyday standard — writing, notes, exams |
| #2½ | F | Slightly harder than HB; crisper point for neat writing |
| #3 | H | Harder, paler — fine lines, technical work |
| #4 | 2H | Hard, light, holds a point — drafting, layout lines |
What is the UK equivalent of a No.2 pencil?
It is simply an HB. If an American instruction, kit list or set of exam directions tells you to bring a "No.2 pencil" and you are shopping in Britain, reach for anything marked HB and you are correctly equipped. You do not need to track down a literal "#2" — though, as it happens, you can buy the genuine numbered article here too (more on that below).
For completeness: a "No.1" maps to roughly a B (soft), and a "No.3" to an H (hard). HB/#2 is the one you want for general writing nine times out of ten.
Why do exams ask for a #2 / HB pencil?
This is where the two scales cause the most confusion, because the answer is different depending on which country's exam you are sitting.
The American reason: mark-reading machines
The "No.2 pencil" instruction is a hallmark of US standardised testing — the kind with bubble answer sheets. The original mark-reading machines (IBM's test scorers from the 1930s onward) detected answers by the electrical conductivity of the graphite on the page, and #2 graphite gave a reliable, consistent reading. Too hard a pencil (#3, #4) left too little graphite to register; too soft (#1) smudged and could trigger false reads. Later machines switched to optical reading — measuring how much light a mark reflects — but #2 stayed the safe, specified choice because its darkness is predictable.
Worth noting in 2026: the SAT in the US moved fully digital in 2024, so it no longer needs a pencil at all, and other US tests are following. The "No.2 pencil" rule is fading even in its homeland — but it persists anywhere paper bubble sheets are still scanned.
The UK reality: black ink, with HB for diagrams
British candidates rarely need a "#2 pencil" in the bubble-sheet sense at all. Under the standard UK exam-board guidance (the Joint Council for Qualifications rules that GCSE and A-level boards follow), written answers are normally to be completed in black ink, and pencil is reserved for diagrams, graphs, maps and scientific or technical drawings — for which an HB is exactly right. HB is dark enough to scan and photocopy cleanly for marking, and hard enough to draw an accurate, erasable line. So the practical British takeaway is: black biro for prose, a good HB for anything you have to draw. Always check the front of your own paper, as instructions vary by board and subject.
Which UK-available pencils are a true #2 / HB?
You have two routes. If you specifically want the genuine American numbered pencil — the literal "No.2" — one is stocked and sold in the UK. If you just want a first-class HB (the same thing, better made), you are spoilt for choice. Here are the five we would actually put in someone's hand, with our pick at the top.
The literal #2: Dixon Ticonderoga Classic Yellow No.2 (HB)
If you want the exact pencil an American means by "#2", this is it — the iconic yellow barrel with the green-and-yellow ferrule, long marketed as America's best-selling pencil and graded No.2 (HB) right on the side. It writes a clean, medium-dark line, sharpens without splintering, and settles any "but it has to say #2" instruction on the spot. We lead with it because it is both the literal answer and a perfectly good everyday writer. (If you specifically want a cedar barrel, the same range includes a Ticonderoga Cedar No.2 — but for most people the Classic Yellow is the one to reach for.)
Our pick — the genuine numbered article, sold in the UK:
Check price → Ticonderoga Classic Yellow No.2 (HB)Want a softer, darker line? Ticonderoga No.1 (extra soft, ~2B)
The same pencil one grade softer. Ticonderoga's No.1 is sold as "Extra Soft"; on the letter scale a #1 conventionally lines up with B, though this one runs soft enough that we catalogue it around 2B. Choose it if you press lightly, want a darker mark, or are buying for a young child still building handwriting pressure. The exact softness of a "No.1" varies between makers, so treat it as "noticeably softer and darker than a #2" rather than a precise grade.
The soft, dark alternative:
Check price → Ticonderoga No.1 (Extra Soft / ~2B)The European HB benchmark: Staedtler Noris 120 HB
If "#2" simply means "a good HB" to you, the black-and-yellow striped Staedtler Noris is the school and office standard across the UK and much of Europe. The HB writes a consistent, mid-tone line, the wood sharpens cleanly, and the break-resistant core survives a school bag. For UK exam diagram work, this is the safe, no-drama choice.
The UK/European everyday HB:

Step up to a Japanese HB and you feel the difference immediately — smoother on the page, darker for the same pressure, and far less gritty than a budget #2. The Mitsubishi (uni) 9800 is the classic affordable Japanese office pencil: a refined, even HB that flatters everyday handwriting. If you have only ever used cheap school pencils, this is the easiest "why is this so nice" upgrade on the list.
The best-value Japanese HB:
Check price → Mitsubishi 9800 HBThe other Japanese classic: Tombow 8900 HB
Tombow's green-barrelled 8900 has been a Japanese stationery staple since the 1940s and is a connoisseur's everyday writer: a clean, dark, beautifully balanced HB that many people prefer to anything Western at the price. A direct rival to the Mitsubishi 9800 — pick whichever barrel you like the look of; both are excellent HBs and both, in American terms, are #2s.
The cult-favourite writing HB:

A #2 pencil is an HB — same grade, two scales. In the UK you almost never need to find a literal "#2": buy any HB and you are sorted. If you want the genuine numbered pencil anyway, the Ticonderoga No.2 is sold here; if you want the best writing experience for the money, a Japanese HB like the Mitsubishi 9800 or Tombow 8900 will quietly outclass the pencil you grew up with. And if your child needs a softer line, drop to a No.1 or B.

FAQ
Is a #2 pencil the same as HB?
For everyday purposes, yes. #2 is the American grade and HB is the UK/European grade for the same medium-hardness graphite. The only nuance is that there is no universal standard, so an HB from one maker can run slightly darker or harder than another's — but any HB will satisfy a "#2 pencil" instruction.
What is a #2½ pencil?
A #2½ (sometimes written 2.5 or "2 4/8") sits between #2 and #3 and corresponds to an F on the letter scale — very slightly harder than HB, giving a crisper point that holds longer. Good for small, neat handwriting.
Can I use any HB pencil for a US exam or the SAT?
If a paper exam still uses bubble sheets, a good HB/#2 with a clean, dark line will be read correctly — the genuine Ticonderoga No.2 removes any doubt. Note that the US SAT went fully digital in 2024 and no longer requires a pencil at all; check your specific test's current rules.
Do UK exams actually need a #2 pencil?
Rarely in the bubble-sheet sense. UK exam boards generally want written answers in black ink and reserve pencil for diagrams, graphs and technical drawings — for which an HB is the right tool. Always read the instructions on your own paper, as they vary by board and subject.
Why does my Ticonderoga feel different from my Staedtler if both are HB/#2?
Because each manufacturer grades against its own reference. Japanese HBs (Mitsubishi, Tombow) tend to feel smoother and darker, European HBs (Staedtler) firmer, and budget American #2s grittier — all while wearing the same label. The grade tells you roughly where a pencil sits, not exactly how it writes.
Can you buy real #2 pencils in the UK?
Yes. The Dixon Ticonderoga Classic Yellow is sold here graded No.2 (HB) on the barrel — the literal American #2. For most people, though, any quality HB is the simpler and often better-writing equivalent.
Sources & notes
- Grade conversion (#1–#4 ↔ B/HB/F/H/2H) is the long-standing industry convention; because no international standard fixes graphite darkness, treat all equivalences as approximate. Verified against manufacturer grade ranges; exact darkness varies by brand.
- Origin of the numbered scale (attributed to John Thoreau & Company / Henry David Thoreau): commonly repeated historical account — flagged as traditional attribution, not fully documented.
- Mark-reading machines: early IBM test scorers read graphite by electrical conductivity; later optical mark readers read by light reflectance. The #2 specification predates and outlived the conductivity era.
- SAT digital transition: the US SAT moved to a fully digital format in 2024 (College Board). Confirm current requirements for any specific exam before relying on this.
