\columnsep ¶\columnseprule ¶\columnwidth ¶The distance between the two columns, the width of a rule between the
columns, and the width of the columns, when the document class option
twocolumn is in effect (see Document class options).
See \twocolumn.
\headheight ¶Height of the box that contains the running head. The default in the
article, report, and book classes is ‘12pt’,
at all type sizes.
\headsep ¶Vertical distance between the bottom of the header line and the top of
the main text. The default in the article and report
classes is ‘25pt’. In the book class the default is: if the
document is set at 10pt then it is ‘0.25in’, and at 11pt or 12pt
it is ‘0.275in’.
\footskip ¶Distance from the baseline of the last line of text to the baseline of
the page footer. The default in the article and report
classes is ‘30pt’. In the book class the default is: when
the type size is 10pt the default is ‘0.35in’, while at 11pt it is
‘0.38in’, and at 12pt it is ‘30pt’.
\linewidth ¶Width of the current line, decreased for each nested list
(see list). That is, the nominal value for \linewidth is to
equal \textwidth but for each nested list the \linewidth
is decreased by the sum of that list’s \leftmargin and
\rightmargin (see itemize).
\marginparpush ¶\marginsep ¶\marginparwidth ¶The minimum vertical space between two marginal notes, the horizontal space between the text body and the marginal notes, and the horizontal width of the notes.
Normally marginal notes appear on the outside of the page, but the
declaration \reversemarginpar changes that (and
\normalmarginpar changes it back).
The defaults for \marginparpush in both book and
article classes are: ‘7pt’ if the document is set at 12pt,
and ‘5pt’ if the document is set at 11pt or 10pt.
For \marginsep, in article class the default is
‘10pt’ except if the document is set at 10pt and in two-column mode
where the default is ‘11pt’.
For \marginsep in book class the default is ‘10pt’ in
two-column mode and ‘7pt’ in one-column mode.
For \marginparwidth in both book and article
classes, in two-column mode the default is 60% of \paperwidth
− \textwidth, while in one-column mode it is 50% of that
distance.
\oddsidemargin ¶\evensidemargin ¶The \oddsidemargin length is the extra distance between the left side of
the page and the text’s left margin, on odd-numbered pages when the
document class option twoside is chosen and on all pages when
oneside is in effect. When twoside is in effect, on
even-numbered pages the extra distance on the left is
\evensidemargin.
LaTeX’s default is that \oddsidemargin is 40% of the
difference between \paperwidth and \textwidth, and
\evensidemargin is the remainder.
\paperheight ¶The height of the paper, as distinct from the height of the print area.
Normally set with a document class option, as in
\documentclass[a4paper]{article} (see Document class options).
\paperwidth ¶The width of the paper, as distinct from the width of the print area.
Normally set with a document class option, as in
\documentclass[a4paper]{article} (see Document class options).
\textheight ¶The normal vertical height of the page body. If the document is set at
a nominal type size of 10pt then for an article or report
the default is ‘43\baselineskip’, while for a book it is
‘41\baselineskip’. At a type size of 11pt the default is
‘38\baselineskip’ for all document classes. At 12pt it is
‘36\baselineskip’ for all classes.
\textwidth ¶The full horizontal width of the entire page body. For an
article or report document, the default is ‘345pt’
when the chosen type size is 10pt, the default is ‘360pt’ at 11pt,
and it is ‘390pt’ at 12pt. For a book document, the default
is ‘4.5in’ at a type size of 10pt, and ‘5in’ at 11pt or 12pt.
In multi-column output, \textwidth remains the width of the
entire page body, while \columnwidth is the width of one column
(see \twocolumn).
In lists (see list), \textwidth remains the width of the
entire page body (and \columnwidth the width of the entire
column), while \linewidth may decrease for nested lists.
Inside a minipage (see minipage) or \parbox
(see \parbox), all the width-related parameters are set to the
specified width, and revert to their normal values at the end of the
minipage or \parbox.
\hsize ¶This entry is included for completeness: \hsize is the TeX
primitive parameter used when text is broken into lines. It should not
be used in normal LaTeX documents.
\topmargin ¶Space between the top of the TeX page (one inch from the top of the
paper, by default) and the top of the header. The value is computed
based on many other parameters: \paperheight − 2in −
\headheight − \headsep − \textheight − \footskip,
and then divided by two.
\topskip ¶Minimum distance between the top of the page body and the baseline of the first line of text. For the standard classes, the default is the same as the font size, e.g., ‘10pt’ at a type size of 10pt.
