How the estimate works
VocaNum samples recognition across several vocabulary difficulty bands. Correct, missed, uncertain, and directly recognized words change the estimate. Early results use less evidence, so their range is wider.

What the number means
The result is a statistical recognition estimate, not a literal count of every word in memory and not a CEFR certificate. Read our English vocabulary size guide for the measurement limits and interpretation.
