# Change font size of \texttt globally?

I'm using TeX Gyre Pagella as the main font of a document which is typeset using a font size of 10pt. For the technical terms, I want to replace the default Computer Modern Typewriter with Bera Mono -- mostly because of the dotted zero. The problem is that now the terms marked with \texttt{} appear too large compared to the rest of the text.

\documentclass[pdftex,fontsize=10pt]{scrbook}

\usepackage{tgpagella}
\usepackage[scaled]{beramono}
\usepackage[T1]{fontenc}

\begin{document}
Lorem ipsum dolor sit amet, consectetur adipiscing elit. Duis non velit in ligula volutpat
condimentum. Now for some technical terms: \texttt{Phasellus}, \texttt{ultrices} aliquam
\texttt{nulla}, in imperdiet magna feugiat sed. Ugh, the technical terms are too large
compared to the rest of the text.
\end{document}


How can I tell (pdf)LaTeX to use a smaller font size (9pt?) for the \texttt{} parts only?

default value for option 'scaled' is '.9. You can set scale to explicit value, e.g., \usepackage[scaled=.7]{beramono}
• excellent! Probably needs to be tweaked on a font-by-font basis. In my case, scaled=0.85 was best, judged by comparing the height of the letter a. – PatrickT Apr 27 '18 at 5:11
