fontspecline-spacing
I am currently using using fontspec to set the mono-space font for my document using
\setmonofont[Scale=MatchLowercase]{Monaco}
The scaling is used to get the font size to match the rest of the document. The size of the characters is scaled, but the line-spacing is not. Is there a way to get the line spacing to scale as well?
For the standard document classes you can use the titling package to do this:
\documentclass{article}
\usepackage{titlesec}
\usepackage{titling}
\usepackage{fontspec}
% Specify different font for section headings
\newfontfamily\headingfont[]{Gill Sans}
\titleformat*{\section}{\LARGE\headingfont}
\titleformat*{\subsection}{\Large\headingfont}
\titleformat*{\subsubsection}{\large\headingfont}
\renewcommand{\maketitlehooka}{\headingfont}
\author{An author}
\title{The title of the article}
\date{\today}
\begin{document}
\maketitle
\section{A section}
\subsection{A subsection}
\subsubsection{A subsubsection}
\end{document}
I can't see what's wrong with scaling the main font:
\documentclass{article}
\usepackage{fontspec}
\setmainfont[Ligatures=TeX,Scale=0.95]{Linux Libertine O}
\usepackage{blindtext}
\linespread{0.95833} % 11.5/12
\begin{document}
\blinddocument
\end{document}
With \Large you'll get 13.4 instead of 14pt; it doesn't seem a big difference (and I'd say it's even better). At \Huge the font will be 24pt instead of 25pt.
This can be supplemented by appropriate \DeclareMathSizes commands, where the last three arguments are scaled at 95%:
\DeclareMathSizes{5}{4.75}{4.75}{4.75}
\DeclareMathSizes{6}{5.7}{4.75}{4.75}
\DeclareMathSizes{7}{6.65}{4.75}{4.75}
\DeclareMathSizes{8}{7.6}{5.7}{4.75}
\DeclareMathSizes{9}{8.55}{5.7}{4.75}
\DeclareMathSizes{\@xpt}{9.5}{6.65}{4.75}
\DeclareMathSizes{\@xipt}{10.4}{7.6}{5.7}
\DeclareMathSizes{\@xiipt}{11.4}{7.6}{5.7}
\DeclareMathSizes{\@xivpt}{13.68}{9.5}{6.65}
\DeclareMathSizes{\@xviipt}{16.42}{11.4}{9.5}
\DeclareMathSizes{\@xxpt}{19.7}{13.68}{11.4}
\DeclareMathSizes{\@xxvpt}{23.64}{19.7}{16.42}

The line spacing is tied to the (nominal) fontsize, it doesn't change when you change the font family. If you want a different line spacing e.g. in a code environment you will have to change
\baselineskiplocally.
