This page contains a list of all Wikipedias under the auspices of the Wikimedia Foundation for various languages.

This list of Wikipedias is based on the List of articles every Wikipedia should have as a sample, which has 1000 articles. For every Wikipedia, the articles in this sample list are retrieved (based on interwiki links in Wikidata) and the number of characters is calculated (minus "comments" and the "interwiki" text at the bottom of the article). The size of each article is then adjusted for each language by multiplying it by the language weight. The articles are divided in four classes: "absent" (i.e. non-existing; size = 0), "stubs" (weighted size in characters less than 10,000), "articles" (size between 10,000 and 30,000) and "long articles" (size more than 30,000). The average weighted size of the non-absent articles in the sample is also calculated. Finally, a score is computed, based on the following formula: rawscore = stubs + articles*4 + long.articles*9 . In order to have a consistent scale the raw score is normalized by dividing by the maximum score and multiplying by 100. The maximum score would be maxscore = (absent + stubs + articles + long.articles)*9 = 9000 (since there are 1000 entries in the list). The final score is the following score = rawscore / maxscore * 100 = rawscore / 90 . The language editions are then listed in order of decreasing score.

For non-English Wikipedias, a check is in place which counts an article as non-existent if too much untranslated English is detected. This prevents artificial score increasing by copy-pasting text from the English Wikipedia.

weights with "*" have no weight available so using default weight of 1.0

weights with "**" use the weight of the known related language (ex. 'zh')

wikis with "†" had a NoSuchSite error during processing

growths with "‡" are the growth attained using previous language weight
