# Finding the cause for an overfull vbox [duplicate]

When compiling my document I get the following warning message:

``````Badbox line 1: Overfull \vbox (1.77525pt too high) has occurred while \output is active []
``````

Now from Google I learned that this warning refers to a formatting problem while Latex is adding headers and footers. Therefore I guess the reference to "line 1" in the warning message does not help me in finding what causes the problem. The first line in my document looks like this:

``````\documentclass[a4paper,oneside]{report}
``````

So my question is this: How can I find what part of my document causes this warning, given the message shown above?

• Welcome to TeX.SX! The first thing to do is to look in the actual `.log` file: `Badbox line 1` is not something that would be output by (La)TeX so it must be the result of some filtering by your editor/IDE. By looking at the actual log message and comparing with the information in the two links in Werner's comments, you should be able to track it down. – Paul Gessler Apr 15 '15 at 0:08
• You have presumably defined a non-standard header, but not declared enough space for that header to be placed. (If you use fancyhdr package to define the header you usually get a warning about that from the package) but unless you make an example that shows the problem, hard to give specific help – David Carlisle Apr 15 '15 at 7:26
• @PaulGessler: Thanks Paul, your comment has helped me to track down the problem. It seems the fully warning message was hidden by Texmaker, so I didn't know there was more to see at all. I found the full `.log` now and thus also the cause for the problem. Thanks! – Matthias Apr 15 '15 at 9:45
