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.
The HSK 3.0 level structure in full
| HSK Level | Cumulative vocabulary | Band | Approx. CEFR |
|---|---|---|---|
| HSK 1 | 500 | Elementary | A1 |
| HSK 2 | 1,272 | Elementary | A1–A2 |
| HSK 3 | 2,245 | Elementary | A2 |
| HSK 4 | 3,245 | Intermediate | B1 |
| HSK 5 | 4,316 | Intermediate | B2 |
| HSK 6 | 5,456 | Intermediate | C1 |
| HSK 7–9 | 11,092 | Advanced | C1–C2 |
Note that HSK 7, 8, and 9 are not separate sub-exams with separate word lists — they form a single advanced band. The 11,092 figure is the combined target for all advanced learners; individual test difficulty within the band varies by the specific exam taken.
HSK 3.0 vs. HSK 2.0 — what changed
The 2021 reform substantially revised both the level structure and the vocabulary lists. Key changes:
- Level count: from 6 to 9 levels, creating more granularity at both elementary and advanced ends
- Vocabulary: the word lists were updated and reorganized; a word that appeared at HSK 3 under the old system may be at HSK 4 or 5 under the new one, and vice versa
- Skills tested: higher levels now formally test productive skills (speaking and writing) more rigorously
- Character count: HSK 3.0 also specifies character requirements separate from vocabulary (words); a character can appear in multiple vocabulary items, so the character count is always lower than the vocabulary count
If you used old HSK 2.0 word lists for your vocabulary study, your functional vocabulary in 3.0 terms may differ because the mapped levels do not correspond one-to-one.
What vocabulary count does and does not predict
Vocabulary size is a strong proxy for overall proficiency because it correlates with reading comprehension, listening scope, and the ability to express ideas. However, the HSK exam also tests:
- Grammar and sentence structure: knowing 3,000 words but not the grammar patterns to combine them will not produce HSK 4 results
- Listening comprehension: native-speed audio at natural pace is harder than the vocabulary count alone suggests
- Handwriting (advanced levels): HSK 7–9 includes character writing by hand, which is a separate skill from recognition
Treat the vocabulary-to-level mapping as a study guide for where to focus, not a substitute for timed practice exams. If your estimated count places you solidly within a level, mock exams under real timing conditions are the best next test of readiness.
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.
