# What is the command to highlight bad boxes in pdf?

I seem to remember a command to show bad boxes in a PDF when using latex, but googling is not helping me to remember.

How can I show bad boxes in my PDF?

-
 add draft to the documentclass options. – Marco Daniel May 9 '11 at 16:50 Is there also an option for underfull hboxes? – white_gecko Apr 22 at 9:30

Pass the draft option to your document class or insert
\overfullrule=5pt

 I vaguely recall some other command, but this certainly does the job. I may be thinking of the ConTeXt command.... who knows. Thanks for your help! – Mica May 9 '11 at 23:46 Doesn't this solution only work for bad hboxes? The question suggests that the OP is also interested in highlighting bad vboxes, but neither the draft option nor \overfullrule=5pt in the preamble accomplishes this. – Tyson Williams Mar 3 at 15:01
