Something you don't see a lot of when reading online are hyphens -- the end of the line kind of hyphen that helps newspaper editors and book publishers get more into tight spaces. Yes, hyphenation can fit more words on the page. But that shouldn't be the main reason for using hyphenation. Do it because it creates more attractive line endings. Do it because it helps to eliminate some widows & orphans (which, in turn, puts more words on the page). Do it because it helps eliminate distracting rivers of white space in fully justified text (which, yes, puts more words on the page). Get to know hyphenaton:
- Soft Hyphen (sometimes you see them, sometimes you don't)
- Hard Hyphen (meant to always be there)
- Hyphenation & Justification - ("they go together like a horse & carriage...")
- Fix Dangling Hyphenated Words (adjust your hyphenation zone)
Other ways to get more on the page? Smaller font sizes and tracking. But as with hyphenation, use it carefully.
