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.

Follow these steps to enable LaTeX:

Visit Jetpack → Settings → Writing in your site’s WP Admin.
Scroll down to the Composing section
Toggle on the Use the LaTeX markup language to write mathematical equations and formulas option.

Now you can begin using LaTeX on your site!

How To Use LaTeX in Posts

To include LaTeX ( $\LaTeX$ ) 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

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

Understanding LaTeX Error Messages

If your LaTeX code is broken, instead of the equation, you’ll see an ugly yellow and red error message.

We can’t provide support for LaTeX 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 LaTeX code inside a LaTeX math environment. If you try to use LaTeX that doesn’t work inside the math environment (such as \begin{align} ... \end{align}), you will get an error:

$\LaTeX&s=X$

How To Adjust LaTeX Size

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

$latex \LaTeX&s=X$

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

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

Changing Colors in LaTeX

WordPress tries to guess the background and foreground colors of your site and generates the LaTeX image accordingly. But, you can also change the colors if you wish. You can do this by specifying bg and fg parameters after the LaTeX 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.

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