# scrlttr2 wider folding marks

I want to use folding marks with my scrlttr2 letters, however my printer margin cuts them off. Thus I want the marks to be a little bit longer/wider so that they reach farther into the document. How can I achieve this?

Here is an example code of my letter.

\documentclass[
paper=a4,
pagenumber=false, % Removes page numbers from page 2 onwards
parskip=half, % Separates paragraphs with some whitespace, use parskip=full for more space or comment out to return to default
fromalign=locationright, % Aligns the from address to the right
foldmarks=true, % Prints small fold marks on the left of the page
]{scrlttr2}
\setkomavar{date}{\today} % Date of the letter
\begin{document}
\opening{To whom it may concern}
This is a letter body.
\closing{yours sincerely}
\end{letter}
\end{document}


Well, following chapter 22.1 in the documentation of KOMA-Script (German version, open it with texdoc koma-script) you can use the command \@setplength to change the value of the relevant pseudolength foldmarkhpos. Because there is a @used in the command you need to use \makeatletter and \makeatother.

Please see the following MWE (changed code marked with <==========)

\documentclass[%
paper=a4,
pagenumber=false, % Removes page numbers from page 2 onwards
parskip=half, % Separates paragraphs with some whitespace, use parskip=full for more space or comment out to return to default
fromalign=locationright, % Aligns the from address to the right
foldmarks=true, % Prints small fold marks on the left of the page
]{scrlttr2}
\setkomavar{date}{\today} % Date of the letter

\makeatletter % <=======================================================
\@setplength{foldmarkhpos}{1cm} % 3,5 mm % \@setplength[Faktor]{Pseudolänge}{Wert}
\makeatother % <========================================================

\begin{document}


Change the value 1cm to that what you need ...
If you are using an own lco file (as I do) you can add the command there (without \makeatletter and \makeatother).
