LaTeX: Vertical Spacing in Multiline Equations

To add some extra spacing in multiline equation environments (such as align or gather), you can use the \jot command either in the preamble which will affect all your multiline equations, or only locally.

\setlength{\jot}{height}

Here’s an example

\begin{align*}
\setlength{\jot}{12pt}
a + c^3 & = 0 \\
a + b^2 & = 0 \\
d + c^{-1} & = 10 \\
d + a^2 & = \pi
\end{align*}

it looks like this

Voila!
