Summary of different ways to measure the English Wikipedia's size

Wikipedia information page

The size of the English Wikipedia can be measured in terms of the number of articles, number of words, number of pages, and the size of the database, among other ways. As of 28 August 2026, there are 7,231,583 articles in the English Wikipedia containing over 5.2 billion words (giving a mean of about 718 words per article). The total number of pages is 66,159,518. Articles make up 10.93 percent of all pages on Wikipedia. As of 26 August 2026^[update], the size of the current version including all articles compressed is about 24.8 GB without media.^[1]

Wikipedia continues to grow, and the number of articles on Wikipedia is increasing by about 15,000 a month (as of July 2024). The number of articles added to Wikipedia every month reached its peak in 2006, at over 50,000 new articles a month, and has been slowly but steadily declining since then. While this might seem to show that Wikipedia's growth is slowing or stopping, it should be noted that the amount of text added to Wikipedia articles every year has been constant since 2006, at roughly 1 gigabyte of (compressed) text added per year. This implies that as time progresses, proportionally more content is added to existing articles rather than new articles, and that Wikipedia has maintained the same persistent rate of growth since the 2010s. In other words, the average article size is growing faster than the number of articles over time.

Most of the earlier entries were extracted from Wikipedia:Milestones. Later entries are taken from observations of the new software's built-in article count features. For information on what Wikipedia's software counts as an article, see Wikipedia:What is an article#Lists of articles and statistics.

The article count of bot-generated Wikipedias such as the Cebuano-language edition of Wikipedia, as well as the Swedish-, Dutch- and the Waray-language editions, grows much faster than those that are primarily written by humans such as the English Wikipedia. Swedish Wikipedian Sverker Johansson's Lsjbot is the primary author of those four primarily bot-generated Wikipedias. Cebuano and Waray are Filipino languages. However, individual articles in bot-generated Wikipedias are on average much shorter than those in primarily human-written Wikipedias.^[2] Thus, article count alone is a very poor indicator of the scale and scope of all Wikipedia editions. However, Lsjbot has been dormant since 2020 and users in the Wikipedias primarily authored by Lsjbot are culling low-quality articles amid concerns about AI-generated content on Wikipedia as a whole with the Swedish and Dutch Wikipedias having their bot-generated articles deleted.

As of March 2026, there are more than 5 billion words in all English Wikipedia articles, with an average of about 717 words per article. There are about 30.6 billion characters, assuming that each word is six characters long (five letters for each word on average plus a space or punctuation mark). Please see the Special:Statistics page for the most recent word count.

The table below shows only the number of words in all content pages, meaning the 7,231,583 articles; it does not include words in other namespaces like Talk, User, or Wikipedia. Data for 2002 through 2010 is from the old Wikistats-1 and thus only precise to the month rather than a specific day within a month. Data for 2018 to the present is from the Special:Statistics page, as saved on that date by the Internet Archive. There is no record of the number of words from January 2010 to December 2017; Wikistats-1 no longer includes the number of words after January 2010, and the Special:Statistics page only started showing the number of words in all content pages on 15 December 2017. Some time within that almost eight-year span, the average number of words dropped. Note that the Internet Archive does not always have an archived version of the Special:Statistics page on the first day of each year.

As of 28 August 2026, there are 66,159,518 pages in the English Wikipedia, of which 7,231,583 (10.93%) are articles, which are found in the main namespace, or simply mainspace. The rest of the pages belong to one of the other 11 namespaces, listed here in alphabetical order: Category, Draft, File, Help, MediaWiki, Module, Portal, Template, TimedText, User, and Wikipedia. Each page on Wikipedia can have a corresponding talk page as well. The data for this table is from the Special:Statistics page, as saved on that date by the Internet Archive. Note that the Internet Archive does not always have an archived version of the Special:Statistics page on the first day of each year. Over time, the percentage of all pages on Wikipedia that consist of articles drops as more non-article pages are created than articles.

There are various elements of the Wikipedia database to consider when describing its size. The most obvious include the markup text of the articles, templates, media/file descriptions, and primary meta-pages that would be needed to render the text of the latest version of the current encyclopedia proper. The associated talk pages and the other namespaces (User, Wikipedia, Help, etc.) are often considered separately. Each of these has an associated edit history, etc. In addition, there are images and other multimedia (stored in common across all Wikipedias). It is important to take into account whether the data is compressed and if so what compression scheme is used. Besides the English Wikipedia, there are hundreds of Wikipedias in other languages to consider, as well.

In April 2010, the size of the full English Wikipedia edit history was 5.6 TB uncompressed.^[4]

As of June 2015, the dump of all pages with complete edit history in XML format at enwiki dump progress on 20150602 is about 100 GB compressed using 7-Zip, and 10 TB uncompressed.

As of May 2015, the current version of the English Wikipedia article/template/redirect text was about 51 GB uncompressed in XML format.

The size of the article text in the English Wikipedia, measured in gigabytes (compressed), grew steadily from 1 GB in 2006 to 9 GB in 2013 to 11.5 GB in 2015 as shown in the chart. However, due to an error in compiling the data dump for April 2016, the size of the article text shrank by approximately 9 percent to 10.8 GB compressed (though the actual size of the article text grew in reality, which can be seen by comparing with the March 2016 and May 2016 data dumps).^[5] Likewise, there is also a similar error when compiling the April 20, 2018, data, showing as 12.85 GB (again, the actual size of the article text grew in reality as can be seen by comparing the previous and following months).^[6]

As of February 2013, the XML file containing current pages only, no user or talk pages, was 42,987,293,445 bytes uncompressed (43 GB). The XML file with current pages, including user and talk pages, was 93,754,003,797 bytes uncompressed (94 GB). The full history dumps, all 174 files of them, took 10,005,676,791,734 bytes (10 TB).^[7]

As of June 2026, Wikimedia Commons, which includes the images, videos and other media used across all the language-specific Wikipedias contained 142,471,025 files, totaling 1,085,665,611,155,968 bytes (987.41 TB). ^[8]

This graph is based on data from https://stats.wikimedia.org/EN/TablesArticlesTotal.htm as of 14 June 2015, with recent values for the English Wikipedia taken from the data below. The sum includes all 270+ Wikipedia languages. See the front page at https://www.wikipedia.org for a recent article count for the ten largest Wikipedias (excluding the Cebuano Wikipedia).

The English edition remains the largest Wikipedia, slightly larger than the second-largest edition, the Cebuano Wikipedia. Many other editions shared the quasi-exponential growth of the English edition, though lagging one to three years behind. As these other Wikipedias have grown, the overall percentage of articles in English has been steadily decreasing, and it fell below 25 percent in March 2007. The percentage of articles in the ten largest Wikipedias has also been decreasing, although these top ten still account for about 67 percent of all Wikipedia articles as of {{{1}}}^[update] June 2007. Note that Lsjbot, a bot run by Sverker Johansson, is responsible for much of the growth of the second- and fifth-largest Wikipedias, the Cebuano and the Swedish Wikipedias, respectively, as well as the rapid growth of the Waray Wikipedia. The charts don't show the Cebuano, Swedish, or the Waray Wikipedias. Those three Wikipedias' article count growth primarily consists of stubs on living organisms and geographical entities (such as islands, rivers, lakes, dams, mountains, and settlements). Growth of the Cebuano and Waray Wikipedias slowed down completely since 2020 and users in those Wikipedias are culling out low-quality articles amid concerns about AI-generated content on Wikipedia. Many Lsjbot-generated articles on the Swedish Wikipedia have been culled since then.

Currently, the English Wikipedia makes up 10.6 percent of all volumes in all editions of Wikipedia.

The English Wikipedia's database size is just over ten times greater than the next-largest Wikipedia by article count, the Cebuano Wikipedia (as of October 2023).

This data set notes the fact that these figures are drawn from multiple data sources and different estimates (see the key below for details), and presents them as a spreadsheet-ready table for graphing. The original data sets are archived: see the links below. Note also that the figures are sampled at random times of day.

In early 2015, Michael Mandiberg published the English Wikipedia in 7473 volumes of 700 pages each via Lulu, an online e-book and print self-publishing platform, distributor, and retailer.^[10]

The following graphic illustrates how large the English Wikipedia might be if the articles (without images and other multimedia content) were to be printed and bound in book form with a format similar to Encyclopædia Britannica. Each volume is assumed to be 25 cm (9.8 in) tall, 5 cm (2.0 in) thick, and containing 1,600,000 words or 8,000,000 characters. The size of this illustration is based upon the live article count manually adjusted by the average word count on an irregular basis on a user subpage of the graphic's original creator Tompw. The growth rate is approximately two full volumes every week if the increase in average article size isn't accounted for over time and approximately two additional full volumes every five days when accounting for increases in average article size. In other words, accounting for increases in average article size over time, the growth rate is approximately two full volumes every three days or one full volume every 36 hours. This rate increases very slowly over time, though it temporarily increases faster during Articles for Creation Backlog Drives. The print volumes as shown in the illustration – with the additional assumption of each volume being 20 cm (7.9 in) wide – would take up just over 9.87 m³ (349 cu ft) in total volume, enough to fill a full-size, high-roof, extended Ford Transit panel van (approximately 13 m³ (460 cu ft) of cargo space) with room to spare for packaging the volumes and reasonable access within the cargo space. In other words, 400 volumes equal 1 cubic meter (35 cu ft).
