Good time of day, Habr!
Recently, I purchased a Kindle 4 and found that reading pdf on it is not very convenient due to the fact that the font is too small. As they say, if it is not possible, but you really want it, then you can!
For the experiments, I created a test pdf page with which I selected various parameters.
')
Remark 1
In order to make the most of the entire screen of the book, I changed the page size and line spacing:
\usepackage{geometry} \geometry{left=0.2cm} \geometry{right=0.2cm} \geometry{top=0.5cm} \geometry{bottom=1.25cm} \linespread{0.95}
Version 1.0. Original
\documentclass[12pt, a4paper]{article}

Simply increasing the font does not help:
\documentclass[14pt, a4paper]{extarticle}

Version 2.0. Page size
\documentclass[14pt, a5paper]{extarticle}

Improvement on the face.
Version 3.0. Final version
This version is fine with me. The text reads well. Everything is seen.
\documentclass[12pt, a6paper]{article}



Version 3.1. Final version-2
Not all eyes are the same - you can still slightly increase the font.
\documentclass[14pt, a6paper]{extarticle}



Remark 2
The last image shows that if you want to place the source code in the
verbatim block, then you should take into account that the code will be cut off on the 40th character, provided that the header is used
\documentclass[14pt, a6paper]{extarticle}
Remark 3
If you already have a document that is typed in tex, then you can simply convert it to Kindle. It is enough to do a few simple edits and the result should be something like this:
\documentclass[14pt, a6paper]{extarticle} \usepackage[utf8]{inputenc} \usepackage[english, russian]{babel} \usepackage[T2A]{fontenc}
Remark 4
Elements that should be paid attention to during this transformation:
- Tables - most tables still do not fit in width
- Images - not all, but very large also climbs the screen border
From experience: images that have been inserted this way:
\begin{figure}[H] \centering \includegraphics[scale=0.5]{imgs/img.png} \caption{ }\label{test_img} \end{figure}
will look quite correct.
Thank.
