How Many German Words Do You Need for B1?

Last updated: October 2026

Short answer

The CEFR levels describe what you can do with the language, not a fixed word count, so there is no single official number. Course materials and vocabulary lists commonly use these figures as rough estimates: about 500-800 words for A1, about 1,200-1,500 words for A2, and about 2,500 words for B1 (see our German B1 exam guide). These estimates mix words you can recognize while reading or listening (passive vocabulary) with words you can actually use in a sentence (active vocabulary) — the two are not the same, and active use matters more for the exam.

A realistic plan if you work full time

Learning while working full-time works better with consistency than with cramming. Adding 5-10 new words a day is a manageable pace that still builds up a few thousand words over several months. The part that actually makes words stick is repeating them at increasing intervals rather than reviewing everything daily: LexyBooster schedules reviews at 1, 3, 7, 14, 30, 60, and 120 days, so a word only comes back once you are close to forgetting it. Each word set also includes audio and translations, so you can review on a commute or during a break instead of blocking out extra study time.

Which words come first

Start with the vocabulary you will actually run into day to day — our Essential German words for expats guide covers the first 100 words for the Jobcenter, the doctor, work, housing, shopping, transport, and school. Once that foundation is in place, move on to the ready-made A1-B1 word sets and exam-topic vocabulary described in our B1 level guide.

Frequently Asked Questions

How many words do I really need for B1?
Course materials commonly estimate about 2,500 words for B1, building on roughly 500-800 for A1 and 1,200-1,500 for A2. These are estimates from vocabulary lists, not an official exam requirement, and being able to use words in context matters more than hitting an exact count.
How many hours a day should I study?
Short, consistent sessions work better than long ones. A focused 10-15 minutes a day of reviewing word sets with spaced repetition adds up over months, while an occasional multi-hour session is easier to skip and easier to forget.
Are word lists enough for the exam?
No. Word lists build the vocabulary foundation, but a B1 exam also tests listening, reading, writing, and speaking in context. Treat vocabulary as the base you practice those skills on, not as exam prep by itself.
What is the difference between passive and active vocabulary?
Passive vocabulary is what you understand when reading or listening; active vocabulary is what you can produce yourself in speech or writing. The word-count estimates for A1-B1 mostly describe passive vocabulary, so active use of a smaller, well-practiced set is often more useful day to day.
