Test Your English Vocabulary
How many English words do you know? Get a rough estimate in minutes with this simple tool. Good luck!
Quick note: this is an estimate, not an official exam or certificate.
How This Test Works
This page uses a sampled vocabulary method.
Instead of asking you about 50,000+ words like an IRS agent at tax time, it shows you a spread of easier and harder words and looks at the pattern of which ones you genuinely know.
From that pattern, it places you into a broad vocabulary range.
That means the result is not a literal word-by-word census of your brain. It’s a practical estimate based on recognition across different difficulty levels. In other words, it is smart enough to be useful, but not so official that it should be framed and hung beside a diploma.
There is also a margin of error.
Vocabulary grows in messy clusters: one person knows weird legal terms from TV dramas, another knows fantasy words from novels, another somehow knows “photosynthesis” but not “ladle.”
So treat your result as a helpful benchmark, and keep trying to improve your lexicon!
English Vocabulary Test FAQ
What counts as knowing a word?
Check a word only if you know at least one real meaning of it. You do not need to know every nuance or every rare definition, but if the word only looks vaguely familiar, leave it blank.
How accurate is this test?
It is reasonably useful, but still rough. Think of the result as a broad estimate with a margin of error, not an exact scientific measurement. Real vocabulary knowledge is too messy to pin down with perfect precision in a quick online quiz.
Is this an official exam or CEFR placement test?
No. This is not an official English exam, school assessment, CEFR certification, or formal placement tool. It is a fast vocabulary estimator meant to give you a useful snapshot of where you roughly stand.
Why might my result feel too high or too low?
Because vocabulary is lumpy. You may know advanced words from work, books, games, or internet rabbit holes while still missing simpler everyday words, or the reverse. The test is looking for your overall pattern, but individual surprises can still pull the result around a bit.
Can beginners and non-native learners use this?
Yes. The test is meant to be useful for a wide range of learners, including beginners and non-native English speakers. Just keep in mind that vocabulary size is only one part of overall fluency.
