I believe there may be a relationship to the 7 plus or minus 2 (times 10)
of human conceptual limits.

Personally I find it very difficult to read text with long lines.

Historically two or three column (newspaper/book) with a barrier margin
was used to get much more text on the page, but still the reader had much
shorter "chunks" to absorb.
