Scale tt font starting from current page

Question

My goal is to scale the tt font down starting someplace in the document. I achieved it by using \fontsize{7pt}{11pt}\selectfont:

\documentclass[parskip=half-]{scrreprt}
\usepackage{lmodern}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[headsepline,plainheadsepline,manualmark]{scrlayer-scrpage}
\begin{document}
\section{Test}
This is a normal text. \large{Large text}
\ttfamily
This is a tt family text. \large{Large text}
\fontsize{7pt}{11pt}\selectfont
This is a tt family text. \large{Large text}
\end{document}

The problem is that \large is still the same size as before.

How I scale everything?

Not directly related but \large doesn't take an argument, that is a switch. — Ulrike Fischer, Aug 26 '21 at 06:13
As long as you always use tt by way of a \texttt{} syntax, rather than a \ttfamily syntax, you could define a new command \newcommand\smalltt[1]{\texttt{\small#1}}, where I chose \small as the desired size, but could be changed to \footnotesize, etc. — Steven B. Segletes, Aug 26 '21 at 09:10

Not sure what's the motivation for this. Anyway…

\documentclass[parskip=half-]{scrreprt}
\usepackage[T1]{fontenc}
%\usepackage[utf8]{inputenc}
\usepackage{lmodern}
\usepackage[headsepline,plainheadsepline,manualmark]{scrlayer-scrpage}
\DeclareFontFamily{T1}{smallercmtt}{\hyphenchar\font-1 }
\DeclareFontShape{T1}{smallercmtt}{m}{n}{
        <-9>    s[0.7] ectt0800
        <9-10>  s[0.7] ectt0900
        <10-12> s[0.7] ectt1000
        <12-17> s[0.7] ectt1200
        <17->   s*[0.7] ectt1728
      }{}
\begin{document}
\section{Test}
This is a normal text. {\Large Large text}
\texttt{This is a tt family text. {\Large Large text}}
\renewcommand{\ttdefault}{smallercmtt}
\texttt{This is a tt family text. {\Large Large text}}
\end{document}

Please, note that \large, like the other size changing commands, does not take an argument but is a declaration whose effect is permanent (obeying the standard scoping rules).

In the example I use \Large just to better show the difference in size.

With fontspec package and TTF/OTF fonts under xelatex/lualatex, the Scale= option can be used:

MWE

\documentclass[parskip=half-]{scrreprt}
%\usepackage[T1]{fontenc}
%\usepackage[utf8]{inputenc}
%\usepackage{lmodern}
\usepackage{fontspec}
\setmainfont{Noto Serif}
\setsansfont{Noto Sans}
\setmonofont{Noto Sans Mono}
\usepackage[headsepline,plainheadsepline,manualmark]{scrlayer-scrpage}
\begin{document}
\section{Test}
This is a normal text. {\Large Large text} {\tiny Tiny text}
\sffamily
This is a sf family text. {\Large Large text} {\tiny Tiny text}
\ttfamily
This is a tt family text. {\Large Large text} {\tiny Tiny text}
Scaled:
\setmainfont{Noto Serif}[Scale=0.4]
\setsansfont{Noto Sans}[Scale=0.4]
\setmonofont{Noto Sans Mono}[Scale=0.4]
\section{Scaled Test}
\rmfamily
This is a normal text. {\Large Large text} {\tiny Tiny text}
\sffamily
This is a sf family text. {\Large Large text} {\tiny Tiny text}
\ttfamily
This is a tt family text. {\Large Large text} {\tiny Tiny text}
\end{document}
