Is it possible in LaTeX, that parentheses scale automatically? When I have a fraction for example I don't want these parentheses to be so small:
I know I can use \left( and \right) to get it the way I want, but I'm annoyed of always typing that. I never want parentheses not to cover what's inside. Is there any way to tell latex to always use \left( / scale automatically and instead manually type whenever I want the default way?

\[ \left(\sum_i \\right)\], so it is better to add\left...\rightonly when actually needed. – daleif Nov 04 '22 at 12:01\left(\right)makes sub-optimal spacing if used when not needed. I'm sure the question must be a duplicate, I'll see if I can find..... – David Carlisle Nov 04 '22 at 15:28
