ConTeXt uses the Latin Modern fonts by default; these fonts looksimilar to the original Computer Modern fonts, but have a much largercharacter repertoire. As it happens, in the Latin Modern (and ComputerModern) fonts, the slanted font does not stand out from theupright font enough for some tastes; so, many people prefer to use theitalic font for emphasis.

There are many other ways of choosing font styles in ConTeXt. If these
basic styles do not satisfy your needs, have a look at the [[Manuals|manuals]],
or ask on the [[ConTeXt Mailing Lists]].
→Switching typefaces
In ConTeXt there are four ways to switch fonts:
* a complete font change ({{cmd|setupbodyfont}}, {{cmd|switchtobodyfont}}).
== Before you start ... == 1. Placing a font switch at the begin of a paragraph can sometimes generate unexpected side-effects. This can be avoided by forcing horizontal mode before any font change:<texcode>\dontleavehmode{\bf Warning!} Care must be taken when a font switch is used at the beginning of a paragraph.\par</texcode> 2. It is usually a bad style to use explicit font switches in the text. It is better to define a semantic command that takes care of the font switching. For example, instead of using <code>{\bf\red important text}</code><texcode>\definehighlight[important][style=bold, color=red]</texcode>and then use <code>\important{important text}</code> in the text. == Font styles and alternatives ==
There are three main types of font styles: serif, sans serif, and teletype. To
You can generally combine font styles with alternatives, so if you want to
switch to bold sans serif, you can use either <code>\bf\ss</code> or
<code>\ss\bf</code>. The various combinations look like the following.
A font switch remains valid for the rest of the ''group''. So, if you want to
And serif again

== Emphasizing text ==
There is a font switch {{cmd|em}} to ''emphasize'' text. This is somewhat
special: it does automatic italic correction and changes the alternative depending
on the current alternative. For example, if the current font alternative is normal (i.e. upright),
{{cmd|em}} switches to slanted; and if the current font alternative is slanted,
{{cmd|em}} switches to normal.

ConTeXt uses the Latin Modern fonts by default; these fonts look
similar to the original Computer Modern fonts, but have a much larger
character repertoire. As it happens, in the Latin Modern (and Computer
Modern) fonts, the slanted font does not stand out from the
upright font enough for some tastes; so, many people prefer to use the
italic font for emphasis. To do that use
<texcode>
\definebodyfontenvironment[default][em=italic]
</texcode>
{{note| For Opentype fonts, italic correction needs to be set using
<texcode>\definefontfeature[default][default][itlc=yes]</texcode>}}
== Font sizes ==
Occasionally one needs to change the use a font sizedifferent from the bodyfont. ConTeXt provides two seriesof commands for that. To increase the For a larger font size, you can use {{cmd|tfa}} to scale
the font size by a factor of <code>1.2</code>, {{cmd|tfb}} to scale by a factor of
<code>(1.2)^2 = 1.44</code>, {{cmd|tfc}} to scale by <code>(1.2)^3 = 1.728</code> and {{cmd|tfd}} to
scale by <code>(1.2)^4 = 2.074</code>.The scale is relative to the current bodyfont size.
To decrease the font size, you can use {{cmd|tfx}}
to scale the font by a factor of <code>0.8</code> and {{cmd|tfxx}} to scale by a factor
of <code>0.6</code>. The scale factors can be a function of the current font size and canbe changed by {{cmd|definebodyfontenvironment}}.
The complete set of relative font sizes are listed below:{| style="border:1px solid #ffcc00; width:100%; padding: 0.5em;" |- align="right"!size||factor ||4pt||5pt||6pt||7pt||8pt||9pt||10pt||11pt||12pt||14.4pt||17.3pt||20.7pt|- align="right"|xx ||0.6 ||4 ||5 ||5 ||5 ||5 ||5 ||6 ||7 ||8 ||10 ||12 ||14.4|- align="right"|x ||0.8 ||4 ||5 ||5 ||6 ||6 ||7 ||8 ||9 ||10 ||12 ||14.4 ||17.3|- align="right" style="background-color: #ffeebb;"|tf ||1.0 ||4 ||5 ||6 ||7 ||8 ||9 ||10 ||11 ||12 ||14.4 ||17.3 ||20.7|- align="right"|a ||1.2 ||4.8||6.0||7.2||8.4||9.6||10.8||12.0||13.2||14.4||17.3 ||20.7 ||24.8|- align="right"|b ||1.44 ||5.8||7.2||8.6||10.1||11.5||13.0||14.4||15.8||17.3||20.7||24.9 ||29.8|- align="right"|c ||1.728 ||6.9||8.6||10.4||12.1||13.8||15.6||17.3||19.0||20.7||24.9||29.9||35.8|- align="right"|d ||2.074 ||8.3||10.4||12.4||14.5||16.6||18.7||20.7||22.8||24.9||29.9||35.9||42.9|-| _|- align="right"|scriptscript|| 0.5 ||4 ||5 ||5 ||5 ||5 ||5 ||5 ||6 ||7 ||9 ||10 ||12|- align="right"|script|| 0.7 ||4 ||5 ||5 ||6 ||6 ||7 ||7 ||8 ||9 ||11 ||12 ||14.4|- align="right"|small|| 0.8 ||4 ||4 ||5 ||5 ||6 ||7 ||8 ||9 ||10 ||12 ||14.4||17.3|- align="right"|big || 1.2 ||6 ||7 ||8 ||9 ||10 ||11 ||12 ||12 ||14.4||17.3||20.7||20.7|} As defined in [[source:font-ini.mkvi|font-ini]]. All sizes in pt, except factor. The mapping of particular command suffixes (a, x, etc.) and current bodyfont size to effective font size canbe changed by {{cmd|definebodyfontenvironment}}. The default values defined in [[source:font-ini.mkiv|font-ini]] are:<texcode>\definebodyfontenvironment [\s!default] [ \s!text=1.0, \s!script=0.7, \s!scriptscript=0.5, \c!a=1.200, \c!b=1.440, \c!c=1.728, \c!d=2.074, *=\currentfontscale, % wildcard \c!x=0.8, \c!xx=0.6, \c!big=1.2, \c!small=0.8, \c!interlinespace=, \c!em=\v!slanted]</texcode>'''N.B.''': <code>scirpt</code> and <code>scriptsize</code> are used in math mode. It is also possible to set the scaling factors for specific font sizes. For example, if you want{{cmd|tfa}} to be equal set the effective font size to 12pt when you are using the bodyfont size is 10pt font, and be equal to set the effective font size to14pt when you are using the bodyfont size is 11pt font, then add
<texcode>
\definebodyfontenvironment [10pt] [a=12pt]
\definebodyfontenvironment [11pt] [a=14pt]
</texcode>
'''Note:''' When the first parameter is <code>default</code>, the scaling factors ''must'' have numerical values. When the first parameter is a font size (e.g., <code>12pt</code>), the scaling factors can either be numerical value or a dimension.
{{cmd|definebodyfontenvironment}} is described in detail in
the ConTeXt manual and the [[source:font-ini.texmkiv|font-ini.tex]] source file.
Font size can be combined with font styles. As a shortcut, you can use
scaled by <code>0.8</code> and similar commands for other font styles.
These quick font size switches are meant for changing the font style, alternative, or size of a fewwords: they do not change the bodyfont, so they don't affect interline spacing and or math font sizes. So, if
you want to change the font size of an entire paragraph, use
{{cmd|switchtobodyfont}} described below in [[Font_Switching#Complete_font_change|Complete Font Change]]. However, it
In addition, the commands {{cmd|smallbodyfont}} and
{{cmd|bigbodyfont}} can be used to change the font size. The relative size depends on the value of <code>big</code> and <code>small</code> in {{cmd|definebodyfontenvironment}}.
These mnemonic font switches are pretty smart. You can either use them as
</texcode>
(<code>\boldface</code> shown above is also defined to parallel the<code>\typeface</code> and <code>\swapface</code> switches.) == Capitalizing words == * Note that {{cmd|WORD}}, {{cmd|Word}} and all following macros aren't ''switches'', but ''commands'' (brackets behind, not around): <tt>{</tt>{{cmd|em}} <tt>switch}</tt>, vs {{cmd|Word}}<tt>{macro}</tt>. == Underline, strike through, and overline == * Underlined, struck, and overlined text can be achieved with {{cmd|overbar}} , {{cmd|overbars}}, {{cmd|overstrike}}, {{cmd|overstrikes}}, {{cmd|underbar}}, and {{cmd|underbars}}. The canonical way is <code>\overstrike{text}</code>. However, it you're using mycrotypography with <code>\setupalign[hz,hanging]</code> expect the rule to be placed over the character (with the Latin Modern fonts you should not have this problem, experienced with Linux Libertine and mkiv). This is not what is expected. The workaround is to put the overstriked text in a <code>\inframed[frame=off]{}</code>. E.g.<texcode>bla bla bla \inframed[frame=off]{\overstrike{striked}} bla bla</texcode> <context>bla bla bla \inframed[frame=off]{\overstrike{striked}} bla bla</context> Disabling mycrotypography also works, but probably not desiderable. <pre>\setupalign[nothanging,nohz]\strikeout{text}\setupalign[hanging,hz]</pre> == Complete font (bodyfont) change ==
If you need to change to a different font size and take care of interline
spacing, you can use change the bodyfont by using {{cmd|switchtobodyfont}}. For example, to switch to 12pt
you can use <code>\switchtobodyfont[12pt]</code>.
ConTeXt provides two relative sizes, called ''big'' and ''small''. So, to go to abigger font increase the bodyfont size , use <code>\switchtobodyfont[big]</code> (or <code>\setbigbodyfont</code>), and to use asmaller font decrease the bodyfont size , use <code>\switchtobodyfont[small]</code>(or <code>\setsmallbodyfont</code>). The exact
size used for big and small can be set using
{{cmd|definebodyfontenvironment}}.
page markings, while {{cmd|switchtobodyfont}} does not. So you should use
{{cmd|setupbodyfont}} for global font definitions to apply to the whole document, and
{{cmd|switchtobodyfont}} for local font changes(i.e. changes to the running text only). The effect of
{{cmd|switchtobodyfont}} can be localized within a group as usual.
== Different Switching typefaces ==
So far we have discussed style and size changes within a given typeface
family. If you want to use a different typeface altogether, such as Times or
Palatino, use `\switchtobodyfont[times]` or `\swtichtobodyfont[palatino]`. Here `times` and `palatino` refer to the name of the Pragma web site has recipes covering all typescript definitions for the commonly availabletypefaces [http://pragmafont. ConTeXt distribution comes with some pre-ade.com/general/manuals/showfontdefined typescripts; if you want to switch to another font, you need to define your own typescript.pdf]For details, while aseparate manual describes how to write support for new typefacessee [[http://pragma-ade.com/general/manuals/mfonts.pdfFonts | the page on fonts]].
