The size of the fonts can be changed globally with the following commands:[table][tr][td]\tiny[/td][td]\scriptsize[/td][td]\footnotesize[/td][td]\small[/td][td]\normalsize[/td][/tr][tr][td]\large[/td][td]\Large[/td][td]\LARGE[/td][td]\huge[/td][td]\Huge[/td][/tr][/table][br]The command [b]\normalsize[/b] back font to its original size. If you want to combine different font sizes should add the commands in braces {...}. This is an example of combination of sizes in [b]math mode[/b].[br][br][b]Example 1:[/b] [br][code]{\scriptsize A}{\footnotesize B}{\small C}{\normalsize D}{\large E}{\Large F}{\LARGE G}{\huge H}{\Huge I}[br][/code][url=https://web.archive.org/web/20240615043817/http://wiki.geogebra.org/en/File:LTX1.PNG][img width=139,height=38]https://web.archive.org/web/20240615043817im_/http://wiki.geogebra.org/uploads/1/1d/LTX1.PNG[/img][br][/url][br]The following is an example of combination of sizes in text/math mode using [b]\oldstylenums{ ...}[/b] command (only math mode).[br][br][b]Example 2:[/b] [br][code]\text{{\Huge GeoGebra}, the most powerful, {\small since }}\oldstylenums{ 2001-2012}[br][/code][url=https://web.archive.org/web/20240615043817/http://wiki.geogebra.org/en/File:LTX2.PNG][img width=444,height=44]https://web.archive.org/web/20240615043817im_/http://wiki.geogebra.org/uploads/d/dc/LTX2.PNG[/img][br][br][/url]We can also use the command in text/math mode:[code]\scalebox{h_scale}[v_scale]{...}[/code] where [b]{h_scale}[/b] is a positive(negative) number (mandatory) and [b][v_scale][/b] is a positive number (optional), numbers can be sliders.[br][br][b]Example 3:[br][/b][code]\scalebox{2}{\text{{\Huge GeoGebra}, the most powerful, {\small since }}\oldstylenums{ 2001-2012}}[br][br][/code][url=https://web.archive.org/web/20240615043817/http://wiki.geogebra.org/en/File:LTX3.PNG][img width=878,height=74]https://web.archive.org/web/20240615043817im_/http://wiki.geogebra.org/uploads/6/68/LTX3.PNG[/img][/url]

In [b]text mode[/b] we have the following families of text, we can use globally or using braces {...}:[br][br][code]\rm[/code] or [code]{\rm } \sf [/code]or [code]{\sf } \tt[/code] or [code]{\tt }[/code][br][br][br][b]Example 1:[br][/b][code]\text{{\rm GeoGebra}{\sf ,the most powerful}, {\tt since }}\oldstylenums{ 2001-2012}[br][/code][url=https://web.archive.org/web/20240615043817/http://wiki.geogebra.org/en/File:LTX4.PNG][img]https://www.geogebra.org/resource/bdens82c/JLiDw9sFiUUuY8II/material-bdens82c.png[/img][br][br][/url]In [b]math mode[/b] we have the following families (default mathrm):[br][br][table][tr][td]\mathcal{ABC}[/td][td]\mathrm{abc}[/td][td]\mathbf{abc}[/td][td]\mathsf{abc}[/td][td]\mathit{abc}[/td][/tr][tr][td]\mathtt{abc}[/td][td]\mathfrak{abc}[/td][td]\mathbb{ABC}[/td][td]\mathscr{ABC}[/td][/tr][/table][b][br]Example 2:[br][/b][code]\mathbb{G}\mathfrak{e}\mathbf{o}\mathsf{G}\mathscr{E}\mathtt{b}\mathit{r}\mathrm{a}[br][/code][url=https://web.archive.org/web/20240615043817/http://wiki.geogebra.org/en/File:LTX5.PNG][img]https://www.geogebra.org/resource/s9xv4uka/0MoWA57zjvmqPP2Q/material-s9xv4uka.png[/img][/url]
