I'm using biblatex for producing the bibliography in my document, and I wish to customize the entries. More specifically, I want to reduce the font size used for the URL as they tend to overflow.

Anyone have any idea how to achieve this?

URLs are formatted (in part) by the url package. Adding


to your preamble should reduce the font size relative to the rest of the bibliography. (The bibliography font size is determined by the biblatex command \bibfont, defined as \newcommand*{\bibfont}{\normalfont\normalsize}.)

  • But doesn't this affect all usage of \url? For instance, I'm using \url in some other places in the document.

    @gablin It would. The \AtBeginBibliography hook can limit the change to within the bibliography - any use of \url before or after \printbibliography would be unaffected.
