The following guidelines are suggested by the National Association for the Visually Handicapped (PDF) and American Printing House for the Blind:
- Maximum trim size of 8.5¨×11¨
- Gutter margins should not be less than 7/8¨.
- The outside margin should not be less than 1/2¨.
- Type size should preferably be 18 pt but not less than 16 pt.
- Sans serif type is preferred.
- Bold text should be used for titles, captions, etc.
- Letterspacing, word spacing, and leading must be adjusted to accommodate the larger type.
- A vertical line must be used to separate columns.
Simply adjusting the size of the fonts isn't enough. You also need to adjust a number of spacing parameters such as paragraph indentation, list indentations, page margins, column gutters, etc.
Currently, the Tufte-LaTeX classes only provide a single set of font sizes (with a base size of 10 pt).
The following code only adjusts the font sizes and some spacing parameters. Save this file as tufte-largeprint.sty and place it in the same directory as your document's .tex file or in the same directory as the rest of your Tufte-LaTeX files.

Now you can add \usepackage{tufte-largeprint} to your tufte-book or tufte-handout document and the font sizes will use a base of 18 pt.
Here's an example document:
\documentclass{tufte-handout}
% Adjusts font sizes and spacing for large print
\usepackage{tufte-largeprint}
% Provides some example text
\usepackage[math]{blindtext}
% blinetext wants to use \subsubsection but tufte-handout doesn't
% provide one. So we'll just make it the same as \subsection.
\let\subsubsection\subsection
\begin{document}
\title{Example large-print document}
\author{Kevin Godby}
\maketitle
% A test of sidenotes.
A sidenote.\sidenote{This is a sidenote. It's much larger than it usually is.}
\blindtext[1]
% A figure to test captions.
\begin{figure}[h]
\rule{\linewidth}{2in}
\caption{My magnum opus \textit{Void}.}
\end{figure}
% An example document
\Blinddocument
\end{document}
Please note that I put this together fairly quickly and there are likely other parameters that need to be adjusted. These parameters are probably suboptimal, as well. Feel free to modify it to suit your needs.
