# Is there a way to control the font size of MathJax equations?

Some equations have nested fractions and radicals e.g.:

Mathjax renders the equation this size:

which makes it hard to read some variables. I am wondering: is any way to increase the size of the font?

• looks like using "\cfrac" instead of "\frac" will help quite a bit with this specific example; still curious if there's font size control though Jan 20 '15 at 20:04

It seems MathJax supports size Latex commands:

• \tiny, \scriptsize, \footnotesize, \small, \normalsize (default), \large, \Large (capital "L"), \LARGE (all caps), \huge, \Huge (capital "H")

Which go from smallest to largest. A quick test showed that \large or \Large worked rather well for the equation you have above (getting larger might be just too much).

However, a temporary fix (for you only) is as follows:

1. Right click on any MathJax equations in any post
2. Select Math Settings
3. Select the last option, Scale all math...
4. Enter any number you want in the pop-up

Note that this applies site-wide (I believe that it edits your JavaScript file) but, again, for you only.
