How to create subsubsubsection

Question

Default latex unfortunately is very limited, and it ends at 3 (for example 1.0.0). How to go one point further? (1.0.0.0)

There is solution somewhere on stackexchange that turns paragraph into subsubsubsections:

\setcounter{secnumdepth}{4}
\titleformat{\paragraph}
{\normalfont\normalsize\bfseries}{\theparagraph}{1em}{}
\titlespacing*{\paragraph}
{0pt}{3.25ex plus 1ex minus .2ex}{1.5ex plus .2ex}

But results are far from expected.

How it should look:

1.0.0.0 Title
Body of paragraphs is here and it works fine

How it looks in reality:

1.0.0.0 Title Body of paragraphs is here and 
it looks terrible

@musarithmia font size gets overriden and there is no way to change it. — PeterParker, Oct 13 '21 at 17:33
Absolutely not. First, your code uses the \titleformat and \titlespacing* macros, whereas mine (cross-referenced above) redefines \paragraph directly, via a \renewcommand instruction. Second, can you spot the difference between 3.25ex plus 1ex minus .2ex and -2.5ex\@plus -1ex \@minus -.25ex? — Mico, Oct 13 '21 at 17:37
Please clarify what you mean by “font size is also overri[d]den.” Which font size is in use? (Both \subsubsection and \paragraph should use \normalsize.) — Mico, Oct 13 '21 at 17:56
@Mico \paragraphfont{\large} for section titles, i have it set for section, subsection, and subsubsection. I need the same thing for our fake subsubsubsection. — PeterParker, Oct 13 '21 at 17:58
Find the part in the code that says \normalsize and replace it with \large. — musarithmia, Oct 13 '21 at 18:15
@PeterParker - And how was I supposed to know that you want \large as the font size for all sectioning commands? Sadly, but maybe not surprisingly, my mind-reading skills are absolutely rubbish. — Mico, Oct 13 '21 at 18:34
you are mistaken the standard classes all have two further levels of heading below subsubsection, \paragraph and \subparagraph (don't be fooled by the names which are just chosen to make it more readable than repeated sub...) — David Carlisle, Oct 13 '21 at 18:37
why is the result "unexpected" ? that is just a matter of expectation. Latex supports two styles of heading display and run-in the documentation for a document class will say what style it uses and in any case it is easy to change — David Carlisle, Oct 13 '21 at 18:39

Default latex unfortunately is very limited,

everything has limitations but latex is not as you describe

and it ends at 3 (for example 1.0.0).

The standard book and report class has 6 levels of heading (chapter (0) through to subparagraph (5)) and article has 5 levels (missing chapter)

The level at which latex stops numbering headings is set by the counter secnumdepth which article sets to 3 so you want

\setcounter{secnumdepth}{4}

Then as documented \paragraph uses a run-in style you could use a package such as titlesec to declare it as a display heading, or simply copy the defintions from article.cls but change the sign to denote a display.

\renewcommand\paragraph{\@startsection{paragraph}{4}{\z@}%
% display heading, like subsubsection
                                     {-3.25ex\@plus -1ex \@minus -.2ex}%
                                     {1.5ex \@plus .2ex}%
                                     {\normalfont\normalsize\bfseries}}

\documentclass{article}
\makeatletter
\renewcommand\paragraph{@startsection{paragraph}{4}{\z@}%
% display heading, like subsubsection
                                     {-3.25ex@plus -1ex @minus -.2ex}%
                                     {1.5ex @plus .2ex}%
                                     {\normalfont\normalsize\bfseries}}
 \setcounter{secnumdepth}{4}
\makeatother
\begin{document}
\section{aaa}
aaa
\subsection{aaa}
aaa
\subsection{aaa}
aaa
\paragraph{aaa}
aaa
\end{document}

Hi David, it seems I couldn't get \subsubparagraph work. It reported Undefined control sequence. ^^I\subsubparagraph when I tried to use it. — Frank, Dec 01 '22 at 01:06

You could use one of the KOMA-classes. They have a number of tools to adapt the sectioning commands

\documentclass{scrartcl}
\setcounter{secnumdepth}{4}
\RedeclareSectionCommand[runin=false,afterskip=0pt,afterindent=false]{paragraph}
\begin{document}
\section{abc}
some text
\paragraph{paragraph} 
some text 
\end{document}

But you should stop to believe that everything that doesn't look like you want it is "terrible". run-in headers are used in many places.

It won't compile with article document class. Yeah I should choose my words more carefully, but I have spent last 2 hours doing this, and in Word it can be done in 30 seconds, so I'm really close to moving to south america and becoming a farmer. – PeterParker Oct 13 '21 at 18:18

well it only took me a minute to write the code above. And I could do it in a minute in other classes too. But you didn't provide a complete example and so nobody knows which class you are actually using. Be aware that LaTeX has a 30 year history, and so there are often various methods to achieve a goal. – Ulrike Fischer Oct 13 '21 at 18:27
@PeterParker From your questions and your comments on them that sounds like a good idea to me --- GOM – Peter Wilson Oct 13 '21 at 18:44
