Beautiful Math with LaTeX

LaTeX is a powerful markup language for writing complex mathematical equations, formulas, and more. Jetpack combines the power of LaTeX and the simplicity of WordPress to give you the ultimate in math blogging platforms.

To enable this feature, visit  Jetpack → Settings → Writing in your site’s WP Admin. Scroll down to the Composing section and toggle on the Use the LaTeX markup language to write mathematical equations and formulas option.

Using LaTeX

To include code in your post, use the following:

$latex your-latex-code-here$

So, for example,

$latex i\hbar\frac{\partial}{\partial t}\left|\Psi(t)\right>=H\left|\Psi(t)\right>$

produces

LaTeX Error

If your code is broken, instead of the equation you’ll see an ugly yellow and red error message. Sorry, we can’t provide support for syntax, but there are plenty of useful guides elsewhere online. Or a quick post in our forums might find you a solution. One thing to keep in mind is that WordPress puts all of your code inside a math environment. If you try to use that doesn’t work inside the math environment (such as \begin{align} ... \end{align}), you will get an error:

LaTeX Size

You can change the size of the LaTeX by specifying an s parameter after the code.

$latex \LaTeX&s=X$

Where X goes from -4 to 4 (0 is the default). These sizes correspond to ‘s font size commands:

s=	font size	Example
-4	\tiny
-3	\scriptsize
-2	\footnotesize
-1	\small
0	\normalsize (12pt)
1	\large
2	\Large
3	\LARGE
4	\huge

LaTeX Colors

WordPress tries to guess the background and foreground colors of your site and generates the image accordingly. But, you can change the colors. You can specify bg and fg parameters after the code to change the background and foreground colors, respectively. The colors must be in hexadecimal RGB format: ffffff for white, 0000ff for bright blue, etc.

$latex \LaTeX&bg=ffcccc&fg=cc00ff&s=4$

LaTeX Packages

WordPress.com uses standard with the following packages:

• amsmath
• amsfonts
• amssymb
