How to remove the warnings "Font shape `OT1/cmss/m/n' in size <4> not available" and "Size substitutions with differences" in beamer?
Add
\usepackage{lmodern}
to your document preamble.
Fonts are typically available only in certain sizes/increments. As an example, the basic article
document class loads only the following sizes (from size10.clo
):
\tiny
@5pt
;\scriptsize
@7pt
;\footnotesize
@8pt
;\small
@9pt
;\normalsize
@10pt
;\large
@12pt
;\Large
@14.4pt
;\LARGE
@17.28pt
;\huge
@20.74pt
; and\Huge
@24.88pt
So, requesting a 15pt
font size using something like
\documentclass{article}
\begin{document}
\fontsize{15}{18}\selectfont Hello world.
\end{document}
leads to LaTeX complaining in the .log
file:
LaTeX Font Warning: Font shape `OT1/cmr/m/n' in size <15> not available
(Font) size <14.4> substituted on input line 3.
...
LaTeX Font Warning: Size substitutions with differences
(Font) up to 0.6pt have occurred.
Using lmodern
removes this restriction by allowing font sizes at arbitrary sizes. For more on font size requirements, see Fonts at arbitrary sizes.
Add \usepackage{anyfontsize}
to your preamble.
You can add this \let\Tiny=\tiny
just after the documentclass
declaration. So, it should look something like this:
\documentclass{beamer}
\let\Tiny=\tiny
Hope this helps! :)
