Overfull \hbox (Line Too Wide)
Overfull \hbox (Xpt too wide) in paragraph at lines N--M.
What this error means
A line of text is wider than the text area, causing text to stick out into the margin. This is a warning, not an error — compilation continues — but it usually produces visually poor output with text outside the page margins.
Common causes
- A long word or URL that LaTeX can't hyphenate
- \texttt{} or verbatim text that can't be line-broken
- An oversized image or table
- Tight column widths in a table forcing content overflow
How to fix it
For long URLs, use the url or hyperref package with automatic line-breaking. For text, add \sloppy to allow looser line-breaking, or manually insert \- to hint where hyphenation is allowed. For images, ensure they fit within \textwidth.
