Aligned equations inside of a TikZ node

Lukasz Lew asked on TeX.SX:

How can I create a tree node with aligned math equations inside?


doesn’t work and


gives a lot of margin and I don’t want to manually tune.

\nodepart from shapes tikz library seems to be overkill and doesn’t do the alignment.

Any ideas?


You could use an aligned environment with inline math inside nodes, their size is automatically calculated. Here’s a small example with such a node in a tree:

\begin{tikzpicture}[every node/.style={rectangle,draw}]
  \node {Example:}
    child {node {%
         a &= bx + c\\
         a+b &= d +1
