&gt;<br>
&gt; To increase the base point size in latex to 12pt, one would start with<br>
&gt;<br>
&gt;     \documentclass[12pt]{article}<br>
&gt;<br>
&gt; To increase the base point size for a latex document mid-document one might add<br>
&gt;<br>
&gt;     \fontsize{12}{12}\selectfont<br>
&gt;<br>
&gt; to the preamble. Ref: <a href="https://tex.stackexchange.com/a/4140/9549" rel="noreferrer" target="_blank">https://tex.stackexchange.com/<wbr>a/4140/9549</a><br>
&gt;<br>
&gt; Since Ipe wraps in \documentclass itself, I tried using the latter method to increase the base point to 12pt, but that didn&#39;t work. Can you suggest another way?<br>
&gt;<br>
&gt; You can see that the base point size is different by comparing the output of running<br>
&gt;<br>
&gt;     iperender -pdf 12pt-base.ipe 12pt-base.pdf<br>
&gt;<br>
&gt; on the ipe/xml file:<br>
&gt;<br>
&gt; &lt;?xml version=&quot;1.0&quot;?&gt;<br>
&gt; &lt;!DOCTYPE ipe SYSTEM &quot;ipe.dtd&quot;&gt;<br>

&gt; &lt;layout paper=&quot;612 792&quot; origin=&quot;0 0&quot; frame=&quot;612 792&quot;/&gt;<br>
&gt; &lt;/ipestyle&gt;<br>

&gt; &lt;/page&gt;<br>
&gt; &lt;/ipe&gt;<br>
&gt;<br>
&gt; with the result of pdflatex on the file<br>
&gt;<br>
&gt; \documentclass[12pt]{article}<br>
&gt; \usepackage{helvet}<br>
&gt; \renewcommand\familydefault{\<wbr>sfdefault}<br>
&gt; \begin{document}<br>
&gt; \thispagestyle{empty}<br>
&gt; Greetings, 12pt<br>
&gt; \end{document}<br>
&gt;<br>
&gt; The same issue arises with 11pt, but then it&#39;s harder to see that the two font sizes are not equal.<br>
