I'm using:


With \vphantom{\sum_{n}} I get the big right parenthesis in the second line which is what I want. How can I get a larger division symbol as well?

  • Larger how? Would it be possible for you to include an image of what you want to achieve?

I understand it's only an example, but your usage of \left and \right is wrong.

 something &\biggl(\sum_{n}\nonumber\\
&\quad+y\biggr) \bigg/ x^2.

enter image description here

  • Why does your code complain in my Tex? :| It says "missing } inserted", "extra \right", "missing \endgroup inserted" etc...

    @Alenanno I forgot to remove a \right.

  • Can you explain why using \left and \right as OP did is wrong? I also learned such usage from some references. I know you always have good reasons for your recommends, so I am very curious now. Nov 14, 2019 at 1:01
  • @TheGreatSeo one cannot have \left in one row of an alignment and \right in another one. Anyway, don’t overuse them, because they tend to make larger delimiters than necessary.

To get the scaled division symbol, you probably want to use the \left ... \middle ... \right construction:
