# Is there any way to automatically scale matching parentheses by default? [duplicate]

I tend to use \left( and \right) (and its cousins) all over the place. Is there a way to make this automatic scaling the default behavior in math mode? On the very rare occasions that I don't want automatic scaling I'd then like to write $$ and $$.
• Yeah, that's the same question. Sad to see that the best option seems to be defining new commands such as \paren{}. – Sebastian Oberhoff Jun 10 '18 at 13:06
• The best option is not using indiscriminately \left and \right. – egreg Jun 10 '18 at 13:16
• Well, that's why you'd still have $$ and $$ to fall back on. But honestly, I could see myself writing pages and pages never needing those once. How could you possibly get into trouble? – Sebastian Oberhoff Jun 10 '18 at 14:02
• I write pages and pages of math never needing a single \left-\right pair. – egreg Jun 10 '18 at 14:03
• I can already see a difference between (x^2) and \left(x^2\right). And it doesn't really hurt to scale the parentheses. – Sebastian Oberhoff Jun 10 '18 at 19:45
