The HSK, or Hanyu Shuiping Kaoshi, is the standard Chinese proficiency exam, and since the 2021 reform it spans nine levels instead of six. Vocabulary size is the clearest single indicator of where a learner sits on this scale, so this checker turns a word count into an HSK level estimate.
How it works
The 2021 HSK 3.0 standard defines a cumulative vocabulary target for each level. The tool compares your estimated word count against these published thresholds and reports the highest level whose target you have met. The bands are 500 words for level 1, 1,272 for level 2, 2,245 for level 3, 3,245 for level 4, 4,316 for level 5, 5,456 for level 6, and 11,092 words across the advanced 7-to-9 band. Each level subsumes the words of the levels below it, so the count is always cumulative.
Alongside the level the tool shows an approximate CEFR alignment. CEFR is the European framework used by universities and employers, and although no official conversion exists, a widely used guide places HSK 4 near B1, HSK 5 near B2, and HSK 6 near C1.
Tips and notes
Be honest about what counts as a known word: recognition in reading is easier than recall in conversation, and the HSK tests both. Because the exam also measures grammar, listening, and from level 4 productive writing and speaking, a vocabulary-based estimate is a starting point, not a guaranteed pass mark. If your count sits just over a threshold, plan to consolidate before taking that level rather than reaching for the next one.
