- As of 3 June 2021, Special:Statistics showed 3,900,411,463 words across 6,310,000 articles implying an average of 618 words per article.
- As of 2021, 32.373 GB (=33,150,377,106 bytes) across 3,909 million words, implying 8.3 bytes/word. ASCII uses 1 byte/character which in turn implies 8.3 characters/word. However, this includes wikimarkup, and 5 char/word plus one for space or punctuation mark is standard, so 6 characters/word will be assumed.
- There are currently 6,313,369 articles, which means 3.90273531473×10 9 words, which means 2.341641188838×10 10 characters.
- One volume: 25cm high, 5cm thick. 500 leaves, 2 pagefaces per leaf, 2 columns per pageface, 80 rows/column, 50 characters per row. So one volume = 8,000,000 characters, or 1,333,333 words, or 2,156.9 articles. (Pictures not included!)
- Sanity check: Encyclopædia Britannica has 44 million words across 32 volumes, or 1,375,000 words per volume.
- Thus, the text of the English Wikipedia is currently equivalent to 2,927.1 volumes of Encyclopædia Britannica.
- In other words, Wikipedia is approximately 91.47 times the size of Encyclopædia Britannica.
