Theoretically there is no limit to how long a title can be. However both search engines and browsers truncate long titles to make their display consistent. W3C state that the length of the title tag should, ideally, be 64 characters including spaces, or less.
- Google truncates at 66 characters or the last complete full word.
- Yahoo truncates at 129 characters.
