% See https://en.wikipedia.org/wiki/Canons_of_page_construction before
% modifying the size of printable area. LaTeX defaults are great.
% If you feel it would help anything, you can enlarge the printable area a bit:
%\usepackage[textwidth=390pt,textheight=630pt]{geometry}
% Also, this is the official recommendation (a bit harsh though):
%\usepackage[textwidth=145mm,textheight=247mm]{geometry}

%%% FONTS %%%
\usepackage{lmodern} % TeX "original" (this sets up the latin mono)

% Optionally choose an override for the main font for typesetting
\usepackage[mono=false]{libertinus} % popular for comp-sci (ACM uses this)
%\usepackage{tgschola} % Schoolbook-like (gives a bit of historic feel)
%\usepackage[scale=0.96]{tgpagella} % Palladio-like (popular in formal logic).

% Optionally choose a custom sans-serif fonts (e.g. for figures and tables).
% Default sans-serif font is usually Latin Modern Sans. Some font packages
% (e.g. libertinus) replace that with a better matching sans-serif font.
%\usepackage{tgheros} % recommended and very readable (Helvetica-like)
%\usepackage{FiraSans} % looks great
% DO NOT typeset the main text in sans-serif font!
% The serifs make the text easily readable on the paper.

% IMPORTANT FONT NOTE: Some fonts require additional PDF/A conversion using
% the pdfa.sh script. These currently include only 'tgpagella'; but various
% other fonts from the texlive distribution need that too (mainly the Droid
% font family).
