I'm looking for either an option of setspace that is between onehalfspacing and doublespacing or an alternative to setspace. Unfortunately, I need to be closer to the Word's 1.5 paragraph spacing to satisfy a thesis requirement.
I'm using a KOMA-script scrbook class, so if there is a built-in functionality, that would be best.
onehalfspacing result is too narrow:

doublespacing is too wide:

\setstretch{1.45} looks about right, but I'm not sure if this is safe to use with regard to list environments and similar. The setspace's documentation is quite terse.
My MWE looks like this:
\documentclass[12pt]{scrbook}
\usepackage{fontspec}
\setmainfont{Times New Roman}
\usepackage[onehalfspacing]{setspace}
\usepackage{lipsum}
\begin{document}
\lipsum[2]
\end{document}
setspace.styreveals, that the three commands\single...,\onehalf...and\doublespacingjust use a\setstretch{...}command, with the factor depending on documentclass' setting of fontsize, i.e.10pt,11pt,12pt. There is no further option except ofnodisplayskipstretch– Jun 15 '14 at 09:00funeral sermonon ARIAL. – Jun 15 '14 at 09:12
