WCAG 2.0 provides a set of requirements one of which relates to line length:

1.4.8 Visual Presentation: For the visual presentation of blocks of
text, a mechanism is available to achieve the following: (Level AAA)

2. Width is no more than 80 characters or glyphs (40 if CJK).

"For people with some reading or vision disabilities, long lines of
text can become a significant barrier. They have trouble keeping their
place and following the flow of text. Having a narrow block of text
makes it easier for them to continue on to the next line in a block.
Lines should not exceed 80 characters or glyphs (40 if CJK), where
glyphs are the element of writing in the writing system for the text..
Studies have shown that Chinese, Japanese and Korean (CJK) characters
are approximately twice as wide as non-CJK characters when both types
of characters are displayed with characteristics that achieve the same
readability, so the maximum line width for CJK characters is half that
of non-CJK characters."
