Whether you are creating a simple document or a complex layout, these tips and tricks will help you get the most out of your text.

Font sizes, families, and styles

Latex normally chooses the appropriate font and font size based on the logical structure of the document (e.g. sections). In some cases, you may want to set fonts and sizes by hand so LaTeX provides several commands for formatting text, including font styles and sizes.

Font size

By default, LaTeX uses the following standard font size for different components of a document:

If you need different font sizes for regular text, the following commands can be used:

Font Size	Command	Output
tiny size	\tiny{LaTeX Document}
script size	\scriptsize{LaTeX Document}
footnote size	\footnotesize{LaTeX Document}
small size	\small{LaTeX Document}
normal size	\normalsize{LaTeX Document}
large size	\large{LaTeX Document}
larger size	\Large{LaTeX Document}
largest size	\LARGE{LaTeX Document}
huge size	\huge{LaTeX Document}

Font style

Font styles and effects are usually not applied in technical documents. Anyway, to change the font style, if needed, you can use the following commands:

Font Style	Command	Output
italic	\textit{texready}
bold	\textbf{texready}
underline	\underline{texready}
small caps	\textsc{texready}
slanted	\textsl{texready}
emphasize	\emph{texready}
typewriter	\texttt{texready}
san serif	\textsf{texready}
roman	\textrm{texready}

if necessary, the font style commands can be embeded into each others, as shown below:

\textit{\textbf{ItalicBoldTexReady}}
\textsc{\underline{SmallcapitalsUnderlineTexReady}}

This example generates the following output:

Font color

By default, LaTeX uses black color for texts. To change the color of specific text, an additional package, \usepackage{color}, must be added in the preamble. The font color can be changed using the color command:

\color{color}{text}

The following table shows different color commands:

Font Color	Command	Output
blue	{\color{blue}BlueTexReady}
green	{\color{green}GreenTexReady}
yellow	{\color{yellow}YellowTexReady}
red	{\color{red}RedTexReady}

There are many standard color names available to be used in LaTeX color command, if the color you want is not available you can define it using:

\definecolor{my_violet}{rgb}{127,0,255}
