I tried to use the following code to get the height of the footnote box :

\documentclass{article}
\begin{document}
Example\footnote{A footnote}. Height : \the\ht\footins.
\end{document}

However, I get 0.0pt. Why and how I can fix this ?

    The height of the footnote box is only known in the output routine. – Henri Menke Feb 27 at 2:12
  • I'm not sure to understand why the box couldn't be generated before, Where is the footnote's content stored before ? – JDMCreator Feb 27 at 2:49
  • I checked the TeXbook because I'm not so familiar with inserts myself, but it remains really vague about this: “For example, material inserted with \insert100 will eventually appear in \box100.” (page 122) Unfortunately, it doesn't say when eventually will be. – Henri Menke Feb 27 at 3:03
  • I ran across this problem and wound up rewrtiting footnote to use savebox commands. See tex.stackexchange.com/questions/314375/… – John Kormylo Feb 27 at 15:21
