A highly accurate and free tool to calculate your true English vocabulary size. Based on Paul Nation frequency algorithm, we calculate your CEFR level and exact word count.
We use a two-stage frequency methodology. Stage 1 analyzes your general word recognition. Stage 2 refines the result to determine your exact CEFR level.

Yes, our multilingual vocabulary test is completely free and based on open-source lexical frequency data.
