<p>Two important aspects of selecting a <em>font</em> are specifying a size
and a style.  The LaTeX commands for doing this are described here.
</p>


<hr>
<a name="Font-styles" class="anchor"></a>
<a name="Font-styles-1" class="anchor"></a>
<h3 class="section">Font styles</h3>

<a name="index-font-styles" class="anchor"></a>
<a name="index-type-styles" class="anchor"></a>
<a name="index-styles-of-text" class="anchor"></a>

<p>The following type style commands are supported by LaTeX.
</p>
<p>In the table below the listed commands, the <code>\text...</code>  commands,
is used with an argument, as in <code>\textit{<var>text</var>}</code>.  This is
the preferred form.  But shown after it, in parenthesis, is the
corresponding declaration form, which is sometimes useful.  This form
takes no arguments, as in <code>{\itshape <var>text</var>}</code>.  The scope of
the declaration form lasts until the next type style command or the end
of the current group.  In addition, each has an environment form such as
<code>\begin{itshape}...\end{itshape}</code>.
</p>
<p>These commands, in both the argument form and the declaration form, are
cumulative; for instance you can get bold sans serif by saying either of
<code>\sffamily\bfseries</code> or <code>\bfseries\sffamily</code>.
</p>
<a name="index-_005cnocorrlist" class="anchor"></a>
<a name="index-_005cnocorr" class="anchor"></a>
<p>One advantage of these commands is that they automatically insert italic
corrections if needed (see <a href="latex2e_19.html#g_t_005c_002f">\/</a>).  Specifically, they insert the
italic correction unless the following character is in the list
<code>\nocorrlist</code>, which by default consists of a period and a comma.
To suppress the automatic insertion of italic correction, use
<code>\nocorr</code> at the start or end of the command argument, such as
<code>\textit{\nocorr text}</code> or <code>\textsc{text \nocorr}</code>.

</dl>

<a name="index-emphasis" class="anchor"></a>
<a name="index-_005cemph" class="anchor"></a>
<p>Although it also changes fonts, the <code>\emph{<var>text</var>}</code> command
is semantic, for text to be emphasized, and should not be used as a
substitute for <code>\textit</code>.  For example, <code>\emph{<var>start
text</var> \emph{<var>middle text</var>} <var>end text</var>}</code> will result in the
<var>start text</var> and <var>end text</var> in italics, but <var>middle text</var>
will be in roman.
</p>
<p>LaTeX also provides the following commands, which unconditionally
switch to the given style, that is, are <em>not</em> cumulative.  They are
used as declarations: <code>{\<var>cmd</var>...}</code> instead of
<code>\<var>cmd</var>{...}</code>.
</p>
<p>(The unconditional commands below are an older version of font
switching. The earlier commands are an improvement in most
circumstances. But sometimes an unconditional font switch is precisely
what you want.)

<p>The <code>\em</code> command is the unconditional version of <code>\emph</code>.
</p>
<p>The following commands are for use in math mode.  They are not
cumulative, so <code>\mathbf{\mathit{<var>symbol</var>}}</code> does not
create a boldface and italic <var>symbol</var>; instead, it will just be in
italics.  This is because typically math symbols need consistent
typographic treatment, regardless of the surrounding environment.
</p>

<a name="index-_005cmathversion" class="anchor"></a>
<a name="index-math_002c-bold" class="anchor"></a>
<a name="index-bold-math" class="anchor"></a>
<p>In addition, the command <code>\mathversion{bold}</code> can be used for
switching to bold letters and symbols in
formulas. <code>\mathversion{normal}</code> restores the default.
</p>
<a name="index-_005coldstylenums" class="anchor"></a>
<a name="index-numerals_002c-old_002dstyle" class="anchor"></a>

<a name="index-package_002c-textcomp" class="anchor"></a>
<a name="index-textcomp-package" class="anchor"></a>

<p>Finally, the command <code>\oldstylenums{<var>numerals</var>}</code> will typeset
so-called &ldquo;old-style&rdquo; numerals, which have differing heights and
depths (and sometimes widths) from the standard &ldquo;lining&rdquo; numerals,
which all have the same height as uppercase letters.  LaTeX&rsquo;s
default fonts support this, and will respect <code>\textbf</code> (but not
other styles; there are no italic old-style numerals in Computer
Modern).  Many other fonts have old-style numerals also; sometimes the
<code>textcomp</code> package must be loaded, and sometimes package options
are provided to make them the default.  FAQ entry:

<p>The commands are listed here in declaration forms. You use them by
declaring them, as with this example.
</p>
<div class="example">
<pre class="example">\begin{quotation} \small
  The Tao that can be named is not the eternal Tao.
\end{quotation}
</pre></div>

<p>The scope of the <code>\small</code> lasts until the end of the
<code>quotation</code> environment.  It would also end at the next type style
command or the end of the current group, so you could enclose it in
extra curly braces <code>{\small We are here, we are here, we are
here!}</code>.  You can instead use the environment form of these commands;
for instance, <code>\begin{tiny}...\end{tiny}</code>.

<a name="index-series_002c-of-fonts" class="anchor"></a>
<p>Select the font series.  A <em>series</em> combines a <em>weight</em> and a
<em>width</em>.  Typically, a font supports only a few of the possible
combinations.  Some common combined series values include:
</p>
<table>
<tr><td><code>m</code></td><td>Medium (normal)</td></tr>
<tr><td><code>b</code></td><td>Bold</td></tr>
<tr><td><code>c</code></td><td>Condensed</td></tr>
<tr><td><code>bc</code></td><td>Bold condensed</td></tr>
<tr><td><code>bx</code></td><td>Bold extended</td></tr>
</table>

<a name="index-weights_002c-of-fonts" class="anchor"></a>
<p>The possible values for weight, individually, are:
</p>
<table>
<tr><td><code>ul</code></td><td>Ultra light</td></tr>
<tr><td><code>el</code></td><td>Extra light</td></tr>
<tr><td><code>l</code></td><td>Light</td></tr>
<tr><td><code>sl</code></td><td>Semi light</td></tr>
<tr><td><code>m</code></td><td>Medium (normal)</td></tr>
<tr><td><code>sb</code></td><td>Semi bold</td></tr>
<tr><td><code>b</code></td><td>Bold</td></tr>
<tr><td><code>eb</code></td><td>Extra bold</td></tr>
<tr><td><code>ub</code></td><td>Ultra bold</td></tr>
</table>
 
<a name="index-widths_002c-of-fonts" class="anchor"></a>
<p>The possible values for width, individually, are (the meaning and
relationship of these terms varies with individual typefaces):
</p>
<table>
<tr><td><code>uc</code></td><td>Ultra condensed</td></tr>
<tr><td><code>ec</code></td><td>Extra condensed</td></tr>
<tr><td><code>c</code></td><td>Condensed</td></tr>
<tr><td><code>sc</code></td><td>Semi condensed</td></tr>
<tr><td><code>m</code></td><td>Medium</td></tr>
<tr><td><code>sx</code></td><td>Semi expanded</td></tr>
<tr><td><code>x</code></td><td>Expanded</td></tr>
<tr><td><code>ex</code></td><td>Extra expanded</td></tr>
<tr><td><code>ux</code></td><td>Ultra expanded</td></tr>
</table>

<p>When forming the <var>series</var> string from the weight and width, drop the
<code>m</code> that stands for medium weight or medium width, unless both
weight and width are <code>m</code>, in which case use just one
(&lsquo;<samp><code>m</code></samp>&rsquo;).

<dt><code>\fontsize{<var>size</var>}{<var>skip</var>}</code></dt>
<dd><a name="index-_005cfontsize" class="anchor"></a>
<a name="index-font-size" class="anchor"></a>
<a name="index-_005cbaselineskip" class="anchor"></a>
<p>Set the font size and the line spacing.  The unit of both parameters
defaults to points (<code>pt</code>).  The line spacing is the nominal
vertical space between lines, baseline to baseline.  It is stored in the
parameter <code>\baselineskip</code>.  The default <code>\baselineskip</code> for
the Computer Modern typeface is 1.2 times the <code>\fontsize</code>.
Changing <code>\baselineskip</code> directly is inadvisable since its value is
reset every time a size change happens; see <code>\baselinestretch</code>, next.
</p>
<a name="low-level-font-commands-baselinestretch" class="anchor"></a></dd>
<dt><code>\baselinestretch</code></dt>
<dd><a name="index-_005cbaselinestretch" class="anchor"></a>
<p>LaTeX multiplies the line spacing by the value of the
<code>\baselinestretch</code> parameter; the default factor is 1.  A change
takes effect when <code>\selectfont</code> (see below) is called.  You can
make a line skip change happen for the entire document, for instance
doubling it, by doing <code>\renewcommand{\baselinestretch}{2.0}</code> in
the preamble.

<a name="index-package_002c-setspace" class="anchor"></a>
<a name="index-setspace-package" class="anchor"></a>

<a name="index-double-spacing" class="anchor"></a>
<p>However, the best way to double-space a document is to use the
<samp>setspace</samp> package.  In addition to offering a number of spacing
options, this package keeps the line spacing single-spaced in places
where that is typically desirable, such as footnotes and figure
captions.  See the package documentation.

<a name="low-level-font-commands-linespread" class="anchor"></a></dd>
<dt><code>\linespread{<var>factor</var>}</code></dt>
<dd><a name="index-_005clinespread" class="anchor"></a>
<p>Equivalent to
<code>\renewcommand{\baselinestretch}{<var>factor</var>}</code>, and
therefore must be followed by <code>\selectfont</code> to have any effect.
Best specified in the preamble, or use the <code>setspace</code> package, as
just described.

<dt><code>\selectfont</code></dt>
<dd><a name="index-_005cselectfont" class="anchor"></a>
<p>The effects of the font commands described above do not happen until
<code>\selectfont</code> is called, as in
<code>\fontfamily{<var>familyname</var>}\selectfont</code>.  It is often useful
to put this in a macro:<br>
<code>\newcommand*{\myfont}{\fontfamily{<var>familyname</var>}\selectfont}</code><br>
(see <a href="latex2e_12.html#g_t_005cnewcommand-_0026-_005crenewcommand">\newcommand &amp; \renewcommand</a>).
</p>
<a name="low-level-font-commands-usefont" class="anchor"></a></dd>
<dt><code>\usefont{<var>enc</var>}{<var>family</var>}{<var>series</var>}{<var>shape</var>}</code></dt>
<dd><a name="index-_005cusefont" class="anchor"></a>
<p>The same as invoking <code>\fontencoding</code>, <code>\fontfamily</code>,
<code>\fontseries</code> and <code>\fontshape</code> with the given parameters,
followed by <code>\selectfont</code>.  For example:
</p>
<div class="example">
<pre class="example">\usefont{ot1}{cmr}{m}{n}
</pre></div>
