调整*所有*等宽文本的相对字体大小？

调整*所有*等宽文本的相对字体大小？

默认情况下，LaTeX 会将等宽文本设置为比默认的衬线（“罗马”）文本更大。选择自定义字体时，这一点尤其明显，例如

\usepackage{fouriernc}
\usepackage{DejavuSansMono}

有没有什么方法可以重新调整只是整个文档都使用等宽字体，而不管上下文如何？

\usepackage[hidelinks]{hyperref}
\usepackage{graphicx}
\usepackage{xcolor}
\usepackage{upquote} % fix rendering of quotes in verbatim context

\section{Base situation}

\begin{minipage}{\linewidth}
Choosing the combination of \verb|fouriernc| the relative font size of inline \verb|\verb| test and inline \texttt{\string\texttt} text is too large. The issue is more pronounced when enabling \verb|DejavuSansMono|, but to a lesser degree present without. Likewise the contents of
\begin{verbatim}
verbatim
environment
\end{verbatim}
and the self-defined

\begin{codeblock}
codeblock
environment
\end{codeblock}
are too large.\footnote{It also should work in \texttt{\string\footnote} context.}
\end{minipage}


\section{Half-fixes}

The issue can be partly solved on a case-by-case basis, but this is undesirable. For instance, setting \verb|\verbatim@font|. 

\makeatletter
\renewcommand\verbatim@font{{\scriptsize}\ttfamily}
\makeatother

For demonstration, here \verb|\verbatim@font| includes \verb|\scriptsize|, which does however not affect \texttt{\string\texttt}. This also affects the default
\begin{verbatim}
verbatim
environment
\end{verbatim}
but not the self-defined
\begin{codeblock}
codeblock
environment
\end{codeblock}
\begin{minipage}{\linewidth}
\footnote{In a footnote, the sizing would be anyway wrong, because {\csname verbatim@font\endcsname\string\scriptsize} is too large as font size correction for monospaced text here.}
\end{minipage}

As a consequence adjustments of the font size have to made in many different places.

恐怕您是从错误的前提出发的。比较一下标准的 Computer Modern 字体：

\documentclass{article}

\begin{document}

Abc \texttt{Abc} Abc

\end{document}

你可以看到等宽字体是更小比罗马字体大。但是，一些等宽字体的设计尺寸相当大。

另一方面，大多数字体包都允许scale或scaled选项，也不DejaVuSansMono例外。

\documentclass{article}
\usepackage{fouriernc}
\usepackage[scaled=0.85]{DejaVuSansMono}

\begin{document}

Abc \texttt{Abc} Abc

\end{document}

在我看来并不是最匹配的，但这是个人喜好。

不相关：utf8x选项inputenc指向一个过时且不受支持的软件包。删除对的调用inputenc（除非您有一个非常旧的 TeX 发行版）。
