I have hard time dealing with paragraph skip while keeping titlesec/titletoc, table of contents, list of figures and indentation the same (this is a french book). I have the following class:

``````\documentclass[11pt,a4paper]{book}
``````

In which I consider everything ok in terms of spacing... except paragraph spacing. I don't want any extra space in titlesec/titletoc, table of contents, list of figures and I want a standard french paragraph indentation.

In top of that, I want the space separating two paragraphs be set to the size of `\normalsize`. Currently, I tried,

``````\newlength{\textsize}
\makeatletter
\setlength{\textsize}{\f@size pt}
\makeatother
\setlength{\parskip}{\textsize}
``````

Indentation is ok, paragraph spacing is ok... but the spacing of elements in titlesec/titletoc, table of contents, list of figures is completely modified.

Then I tried:

``````\usepackage{parskip}
\frenchspacing
``````

it protects the table of contents and the list of figures but introduces spaces in titlesec/titletoc and seem to remove indentation.

How to :

• but... introduces a line skip of `\normalsize` between paragraphs?
• I don't quite get you: if you want french spacing, `\parskip=0pt` (or `0pt plus 1pt` if need be). Or do I miss something? – Bernard May 26 '15 at 8:07
• frenchspacing was just a test. I need `\setlength{\parskip}{\textsize}` keeping the tocs/list of figures the same... – Vincent May 26 '15 at 8:40
