% Page Layout and Fonts
% =============================================================================
% General Page Dimensions
% JET requires A4 210 width split with two 22.5mm margins and textwidth of 165mm
% We express this by setting the margin as 22.5mm - 1 inch = 22.5 - 25.4 = -3.1
\newlength{\jetpponecolwidth}
\setlength{\jetpponecolwidth}{165mm}
\newlength{\jetpptwocolwidth}
\setlength{\jetpptwocolwidth}{80mm}
\setlength{\textwidth}{\jetpponecolwidth}
\setlength{\oddsidemargin}{-3.1mm}
\setlength{\evensidemargin}{-3.1mm}
\setlength{\marginparsep}{0mm}
\setlength{\marginparwidth}{0mm}
% Vertical settings : A4 height is 297
%
% JET requires top margin of 25mm to text top : no headers used
% Express this with relation to voffset as : 25mm - 1inch = 25mm - 25.4mm = -0.4mm
\setlength{\topmargin}{0.0mm}
\setlength{\headheight}{0mm}
\setlength{\headsep}{0mm}
% Bottom margin is nominally 30mm to bottom of text, with 15mm footskip
% This leaves a text height of 297 - 30 - 25 = 242
\setlength{\textheight}{242mm}
\setlength{\footskip}{15mm}
\setlength{\parindent}{5mm}
\setlength{\baselineskip}{18pt}
