paperwidth=pwidth and paperheight=pheight, or as papersize=
{pwidth,pheight}.
• By default, the other layout parameters are set so that \textwidth is
80% of \paperwidth and \textheight + \headheight + \headsep
+ \footskip is 90% of \paperheight, centered horizontally and
vertically.
• The text width and height may be set explicitly with width=width
and height=height, or with body={width,height}. The margins are
then set to center. Here height means total text height including
head and footlines.
• Margins may be explicitly given with left=lmarg and right=rmarg,
or with hmargin={lmarg,rmarg}. Similarly with top=tmarg and
bottom=bmarg, or vmargin={tmarg,bmarg}. If only one value of a
pair is given, the other is set to that same value, unless the corresponding
text height or width has been given explicitly. All margins
may be set to a common value with margin=marg.
Unlike L AT E X standard \oddsidemargin and \topmargin, geometry’s
margins are measured from the edge of the paper, and not from a
point 1 inch removed.
• With nohead, nofoot, noheadfoot, one tells geometry not to include
the corresponding head or footline in the height calculation.
Thus with noheadfoot, the total height is identical to \textheight.
• With includemp, the marginal note parameters \marginparwidth
and \marginparsep (Section 4.10.5) are included in the total width
calculation, which is then less than \textwidth. With reversemp,
the marginal notes appear in the left margin.
• The text width and height may be set to a fraction of the paper
size with hscale=h and vscale=v, or scale={h,v}. With scale=s,
both h and v are set to s. For example, \geometry{scale=0.8}
sets width and height to 80% of \paperwidth and \paperheight
respectively.
• For two-sided output, add the option twoside. In this case, the values
of the left and right margins will switch for even page numbers.
In addition, a quantity of 20 pt is added to and subtracted from
the left margin of odd and even pages, respectively. This value may
be changed with twosideshift=shift, which also sets the twoside
option automatically.
• With the verbose option, the calculated values of all the layout
parameters are printed to the monitor and to the transcript file.
