typesetting the document which fits into marked fixed lines

Question

I have a to typeset the article such that, the output should be printed on the fixed marks that are 1.36 cms apart.

In other words, printing sheet has marked lines which are 1.36 cms apart. I have to type with font 11 or 12 whcih fits into these marked lines. Also, how can decide the maximum font size that i can fit between any two fixed lines.

Answer 1

Rather than use \large and friends, you want to set the font size and baseline skip "by hand"

 \fontsize{1cm}{1.36cm}\selectfont

The first size is the font size, you will just need to choose that by eye, depending on which font you are using. The second is baselineskip.

You also then want to set \parskip to a multiple of \baselineskip so it does not push you off grid at a new paragraph. That is, in your preamble go something like

 \raggedbottom
 \newlength\myline
 \setlength{\myline}{1.36cm}
 \setlength{\parskip}{0\myline}% this puts no vertical space between paragraphs
 %\setlength{\parskip}{1\myline}% uncomment this if you want exactly one blank line

If you just have text and paragraph breaks, that should be enough. If you also have (say) itemized lists you will need to similarly set spaces such as \itemsep to be a multiple of \myline so that the itemized points still end up between your lines.

Answer 2

To see what is happening use the following MWE

\documentclass{tufte-book}
\usepackage{lipsum}
\begin{document}

\hrule
\vrule height1.36cm \hbox{\HUGE Test a line of texg}
\hrule
\vrule height1.36cm \hbox to 1.36cm{\Huge Test a line of texg}
\hrule
\vrule height1.36cm \hbox to 1.36cm{\huge Test a line of texg}
\hrule
\medskip

\baselineskip1.36cm
\lipsum[2]
\end{document}

If a 0.4pt accuracy is important to you, adjust vrule by changing the lines to:

\vrule height\dimexpr1.36cm-0.4pt \hbox to 1.36cm{\HUGE Test a line of texg}

You can select a reasonable size after the test, or simply use:

\fontsize{1.13cm}{1.36cm}\selectfont

(try and keep a ratio of 1.2-1.3).
