This is the estimated number of entries in a standard dictionary for which you know at least one definition.
Thanks for taking the test! Based on participations so far, we've already got some decent statistics. Most native English adult speakers who have taken the test fall in the range 20,000–35,000 words. Click here for a full breakdown by age (opens in new tab/window).
And for foreign learners of English, we've found that the most common vocabulary size is from 2,500–9,000 words. Click here for the full distribution (opens in new tab/window).
However, we still need more data for complete analysis by age or education level, especially for participants under 15.
So please share this test, via sites like Facebook (), Twitter (new, share your score: ) , or by plain word-of-mouth. We especially need participation from children and teenagers, where the biggest vocabulary growth occurs, so families are key. (For little kids, obviously they'll need a parent or older sibling to help!)
Over the coming months, we will continue to update our statistics as more data comes in. To save your personal result, you can bookmark this page with your result using the link that appears directly below your result.
