If you mean “more than half” - no one did.

If you mean “more books than any other” it would be St. Paul. 14 books.

However, if you mean “more text” it is arguably still St. Paul.
16 + 16 + 13 + 6 + 6 + 4 + 4 + 5 + 3 + 6 + 4 + 3 + 1 + 13 = 100 chapters

Followed by St. Luke:
24 + 28 = 52

Followed by St. John:
21 + 5 + 1 + 1 + 22 = 50 chapters.

There are eight authors overall, and only within top three, St. Paul wrote slightly less than half he textmass. I am taking “chapter” as a unit of text length, because while pericopes can be long or short according to content, a “chapter” is a unit of (in the larger books, excepting psalms) c. 30 verses. There are exceptionally long chapters, like Luke 1, but exceptionally short ones are often one chapter books (two by St. John, one by St. Paul).

If the top three authors are at 202 chapters, what do the rest contribute beyond that?

Peter:
5 + 3 = 8 chapters

Matthew + Mark + James + Jude (one book each)
28 + 16 + 5 + 1 = 50

So the New Testament has 260 chapters, and St Paul wrote 100. 38.46 %. But, as said, that is more than anyone else, and more than half of the books (14, vs 13 by others).
