This is obviously a noob question but I just can't figure out how to do this.
Inside a geo node I have a modeled object “foo” and a line “bar”.
Now I want the length of the line “bar” to be $SIZEX of “foo”.
How do I reference this value accross? There's probably a simple function or so, I forgot about.

Hello.
bbox expression function gives you size of bounding box along each axis.
something like:
bbox(“your node”, D_XMAX)* 2 —–> equivalent to $SIZEX

Exactly what I was looking for, thanks.

may be better to actually use
