Wikipedia Page Popularity Meter is a free Chrome extension that allows users to see the relative popularity of pages on Wikipedia. Developed by KDJ, this simple yet useful tool displays a meter that indicates how popular a page is compared to others.

The extension was created to address the need for users to quickly gauge the popularity of a Wikipedia page. It can be easy to get lost in the depths of obscure subfields while studying, and this extension acts as a barometer, indicating how deep into a subject the user has gone and when it may be time to resurface. Additionally, it adds an element of fun by allowing users to compare the popularity of different pages.

The popularity of each page is measured by comparing the approximate number of page views over the past 30 days to that of the 10th most popular article. The extension also provides additional information about each article's view statistics through mouseover text.

Wikipedia Page Popularity Meter supports all languages and utilizes storage permission to cache page statistics, reducing the need for frequent data fetching. The square root scale used in the meter effectively represents the great variation in page views between different articles.
