How this tool works1 2 3
Use hsk checker with a clear learning goal
Estimate how a Chinese passage maps to the HSK 3.0 character inventory. The checker reports unique Hanzi coverage, the highest mapped level, the distribution across levels, and characters outside the bundled curriculum data.
Read the distribution
Compare unique-character counts across HSK 1 through the combined 7–9 band.
Inspect unmapped Hanzi
Review names, rare forms, or curriculum-external characters instead of treating them as automatic proof of difficulty.
When to use it
Choose reading material
Compare a passage with the learner's current character coverage before assigning it.
Adapt a lesson
Find advanced or unmapped characters that may need a gloss or pre-teaching.
Check your own writing
See whether a draft relies heavily on vocabulary beyond an intended HSK band.
Questions about hsk checker
Does the checker grade grammar?
No. It maps individual Hanzi to the bundled HSK 3.0 data and does not score grammar or comprehension.
Why is a common name marked unmapped?
Personal names and specialized terms often sit outside curriculum lists even when a learner can understand them.
Are repeated characters counted once?
Coverage and level distribution use unique Hanzi, while the text-size figure also reports total Hanzi.
