There are some useful statistics for the Greek NT listed here by Felix Just; including the Number of Chapters, Number of Verses in Each Chapter, Total Number of Verses, and Total Number of Words in each book of the Greek New Testament.
But what I would like to know is the number of letters in each book of the Greek New Testament (any critical edition accepted; or even TR for comparison). Any offers?
Rhalfs (Textual Criticism of the GNT [ET, 1901], 48f) reports that Zahn (Geschichte des N.T. Kanons, i.76) gives figures from work done by Graux (Revue de Philologie, ii). Rhalfs only provides some figures (letters first, then stichoi [I can't figure out how to do a table]):
Matthew: 89,295 (2,480)
Mark: 55,550 (1,543)
Luke: 97,714 (2,714)
John: 70,210 (1,950)
Acts: 94,000 (2,610)
3 John: 1,100 (31)
Apocalypse: 46,500 (1,292)
Philemon: 1,567 (44)
Looks like a trip to the library to get all the figures; unless someone has Zahn on their shelves.
