How many words do you need to know in English?

For A1 you need up to 1,500 English words, for A2 1,500–2,500, for B1 about 3,000 and for B2 about 3,500. These are words you recognise when reading, counted as word families: work, works, worked and worker count once. English is the best-studied language for this question, so the numbers come straight from research on English learners. Below you’ll find a level table, how much of a text the top words cover, the first words to learn and how long it all takes.
