# [Tex/LaTex] Setting specific values for page size and margins in Koma Script

bleedkoma-scriptmarginsscrbook

I am using a two-sided, a5 paper scrbook for a document where I need to meet very concrete specifications, i.e. the page size needs to have a bleed margin of 3mm, so the size would be totalling 154mm x 216mm.

I came across the following possible solutions:

• \pdfpagewidth and \pdfpageheight as shown here
• the geometry package as shown here
• setting the paper and let the DIV be calculated as shown here

However, the first one did not seem to work, and the second and third lead to problems with the text taking way less space than I thought it to do, seemingly because of the fontsize of 10pt.

The first one does not seem to work at all, while setting the font to 10pt and using paper=154mm:216 leads to this, which has too much margin:

and adding DIV=calc as leads to this result, which has too few margin:

I actually want the same margin I get when I specify paper=A5 just with the smaller font and the added bleed:

So, what is the appropriate way to realize above specifications while not corrupting type area calculations or anything?

My code:

\documentclass[
paper=154mm:216mm, %does not help
DIV=calc, %does not help either
twoside,
fontsize=10pt]{scrbook}

\usepackage{showframe} % added to make it easier to see the layout
\usepackage{blindtext}

\begin{document}
\blindtext[2]
\end{document}


Maybe

\usepackage[width=154truemm,height=216truemm,center]{crop}


does what you want:

Code:

\documentclass[
twoside,
a5paper,
fontsize=10pt]{scrbook}

\usepackage{showframe} % added to make it easier to see the layout
\usepackage{blindtext}
\usepackage[width=154truemm,height=216truemm,center]{crop}

\begin{document}
\blindtext[2]
\end{document}
