我知道这在技术上是错误的，我甚至不应该尝试这样做...尽管如此，我有一个文档，其中的节标题大小设置为，Large并且在任何地方都可以正常工作除了一个部分太长了。我想更改字体大小仅限该部分标题使其看起来更漂亮（即使与其他部分标题的大小不一致）
我唯一能做到的是改变尺寸本地通过做
\section{\large{My very long section title}}
然而，这会使标题和目录变得混乱，因为那里的字体也发生了变化。
我曾尝试使用minipage或包装部分命令\begin{small}--\end{small}，但由于部分标题大小是在其他地方定义的，所以没有任何变化......
这是一个 mwe：
\documentclass[12pt,twoside,a4paper]{report}
\usepackage{lipsum}
\usepackage{fancyhdr} % To change header and footers
\pagestyle{fancy} % Turn on the style
\fancyhf{} % Clears everything in the header and footer
\fancyfoot[CE,CO]{\thepage} %Page number centered in all pages
\fancyhead[LE]{\slshape\nouppercase{\leftmark}} %Chapter title in the outer margin of even pages
\fancyhead[RO]{\slshape\nouppercase{\rightmark}} %Section title in the outer margin of odd pages
\begin{document}
\tableofcontents
\chapter{My chapter}
\lipsum[3-6]
\section{This title is great}
\lipsum[3-10]
\section{This title is veryvery veryveryvery increadibly and mindblowingly very very superlong}
The title is 3 lines long! It would look much better if I could just very slightly reduce the font size, so that it fits in two lines.
\bigskip
\lipsum[3-2]
\section{Some other nice title}
\lipsum[3-8]
\section{\large{This title is veryvery veryveryvery increadibly and mindblowingly very very superlong}}
Great! it is now 2 lines... but the header is huge! and look at the table of contents!!
\bigskip
\lipsum[3-2]
\end{document}
结果是这样的：
答案1
您可以使用以下内容：\chapter[short title in header & TOC]{long title in document}
\documentclass[12pt,twoside,a4paper]{report}
\usepackage{lipsum}
\usepackage{fancyhdr} % To change header and footers
\pagestyle{fancy} % Turn on the style
\fancyhf{} % Clears everything in the header and footer
\fancyfoot[CE,CO]{\thepage} %Page number centered in all pages
\fancyhead[LE]{\slshape\nouppercase{\leftmark}} %Chapter title in the outer margin of even pages
\fancyhead[RO]{\slshape\nouppercase{\rightmark}} %Section title in the outer margin of odd pages
\begin{document}
\tableofcontents
\chapter{My chapter}
\lipsum[3-6]
\section{This title is great}
\lipsum[3-10]
\section[This title is a bit shorter]{This title is veryvery veryveryvery increadibly and mindblowingly very very superlong}
The title is 3 lines long! It would look much better if I could just very slightly reduce the font size, so that it fits in two lines.
\bigskip
\lipsum[3-2]
\section{Some other nice title}
\lipsum[3-8]
\chapter[This title is short]{\large This title is veryvery veryveryvery increadibly and mindblowingly very very superlong}
Great! it is now 2 lines... but the header is huge! and look at the table of contents!!
\bigskip
\lipsum[3-2]
\end{document}
答案2
使用组内的\titleformat*命令，如下所示：titlesec
\documentclass[12pt,twoside,a4paper]{report}
\usepackage{lipsum}
\usepackage{titlesec}
\usepackage{fancyhdr} % To change header and footers
\pagestyle{fancy} % Turn on the style
\fancyhf{} % Clears everything in the header and footer
\fancyfoot[CE,CO]{\thepage} %Page number centered in all pages
\fancyhead[LE]{\slshape\nouppercase{\leftmark}} %Chapter title in the outer margin of even pages
\fancyhead[RO]{\slshape\nouppercase{\rightmark}} %Section title in the outer margin of odd pages
\begin{document}
\tableofcontents
\chapter{My chapter}
\lipsum[3-6]
\section{This title is great}
\lipsum[3-10]
\section{This title is veryvery veryveryvery increadibly and mindblowingly very very superlong}
The title is 3 lines long! It would look much better if I could just very slightly reduce the font size, so that it fits in two lines.
\bigskip
\lipsum[3-2]
\section{Some other nice title}
\lipsum[3-8]
{
\titleformat*{\section}{\Large\bfseries\itshape}
\section{This title is veryvery veryveryvery increadibly and mindblowingly very very superlong}}
Great! it is now 2 lines... but the header is huge! and look at the table of contents!!
\bigskip
\lipsum[3-2]
\section{Some other nice title}
\end{document}
