How many English words do you know?
Tick the words you know out of 144 and get an estimate of your English vocabulary, your CEFR level and the words of your level you do not know yet. Six screens, about three minutes, nothing to install.
The words are English; the test itself is in your language. No account needed — the result is yours to share.

How it works
A checklist, not an exam
The method is the one used in vocabulary research: a yes/no checklist with invented words mixed in, so guessing can be measured rather than assumed.
-
1
Tick what you know
Six screens of 24 words, drawn from the 5,700 most useful English words across the six CEFR levels. Tick a word if you know what it means; leave it if you are not sure. An unknown word costs no tap, which is why 144 items fit in three minutes.
-
2
Invented words keep it honest
Twenty-four of the words do not exist. Ticking them lowers the score, so the estimate reflects what you know rather than how boldly you tick — and a result with too many invented words ticked says so.

3
A number, a level, and what to learn
You get an estimate like "≈ 2,600 words", the share of each level you hold, the CEFR level worth studying next, and the words of that level you did not tick. One tap turns them into your first lesson in LangOrbit.
The scale
How many words is a level?
The test measures against the words of the LangOrbit programme — the CEFR word lists from A1 to C1 plus a C2 list — so a result maps straight onto a level.
| Level | Words at this level | Vocabulary in total | What it lets you read |
|---|---|---|---|
| A1 | ≈ 840 | ≈ 840 | Signs, menus, short messages |
| A2 | ≈ 810 | ≈ 1 650 | Simple stories and texts written for learners |
| B1 | ≈ 680 | ≈ 2 300 | Plainer originals with a dictionary at hand — A Study in Scarlet, A Little Princess |
| B2 | ≈ 1 270 | ≈ 3 600 | Most originals — A Christmas Carol, A Room with a View |
| C1 | ≈ 1 260 | ≈ 4 900 | Press, essays, demanding prose — Notes from the Underground |
| C2 | ≈ 830 | ≈ 5 700 | The top of the scale; the test has nothing harder to ask |
Distinct words, at the easiest level each is listed; counted on 22 September 2026 and rounded. A "word" here is a dictionary headword — knowing "run" covers "runs" and "ran". Book examples are titles from the LangOrbit library and their CEFR tags.
FAQ
About the test
How many English words do you need to know?
On this scale, roughly 1,600 words cover A2, 2,300 reach B1, 3,600 B2 and 4,900 C1. Everyday conversation and simple texts are within reach at 2,000–3,000 words; most original books feel comfortable from around 3,500, with a dictionary for the rest. An educated native speaker knows tens of thousands — but the first few thousand carry most of any text.
How accurate is the estimate?
Two sittings by the same person differ by about 4% at C1, 6% at B2, 9% at B1 and 12% at A2 — measured by simulation, not promised. The result is shown as "≈" with a range for that reason. Precision is set by the number of words, which is why the test asks 144 rather than 40.
Why are there invented words?
They measure over-claiming. Everyone ticks a few words they half-recognize; the invented words show how often that happens for you, and the estimate is corrected by it. If you tick many of them, the result carries a warning and the fair thing to do is to take the test again, ticking only the words you really know.
Do I need an account?
No. The test runs without a signup, and the result page has a link you can share. An account is needed only if you want to learn the words the test found: then your level is set from the result and the first lesson is built from those words.
What happens after the test?
You can share the result, take the test again, or start learning. "Learn these words" opens LangOrbit with your level already set — the level question is skipped — and the first lesson made of the words of your level you did not tick. Take the test again in a month to see the number move.
Is it a placement test for English?
It places you by vocabulary only — the CEFR level in the result is the level whose words you do not yet mostly hold, so it is the level worth studying. Grammar, listening and speaking are not tested; LangOrbit's grammar map and lessons take care of those once you are in.
