Text Formatting ⇒ How to change size of fons in \chapter{} or \section{} part

[user22741]

Hi, I'm starting using Latex, and I need some help with the problem I have.
I have created document like this:

Code: Select all

\documentclass[12pt,a4paper,titlepage]{report}
\usepackage[utf8]{inputenc}
\usepackage[top=2cm, bottom=2cm, left=2.5cm, right=2.5cm]{geometry}
 
\title{Nazwa projektu}
\date{}
 
\begin{document}
\maketitle
\tableofcontents
 
\chapter{chapter 1}
\section{ sec 1}
\section{sec 2}
text text text TEXT text
 
 
\end{document}

and now I want to change size of font for \chapter \section \subsection etc. parts (at best for whole document), but all methods I've tried like \small, \fontsize{}{} don't work for this parts of text - just normal text changes. Now the text there is too large, so it doesn't fit in one line and don't look esthetic.
I would appreciate the help very much

You can use package titlesec to customize your chapter and section titles.

Welcome to the forum!

Compare it to

\documentclass[headings=normal,a4paper]{scrreprt}

or

\documentclass[headings=small,a4paper]{scrreprt}
