LaTeX How do I auto-fit brackets and fractions in Latex without using \Bigg?

AI Thread Summary
The discussion centers on a user who has lost their LaTeX code for a dissertation and is seeking help to restore an auto-fitting feature for brackets and fractions. They recall having a specific line of code that managed resizing automatically but cannot remember it. Another participant clarifies that using the commands \left( \right) and similar for other brackets allows LaTeX to automatically resize them without needing to specify sizes like \big or \Big. The conversation emphasizes the simplicity of using these commands for automatic adjustments in LaTeX, while also prompting the user to provide more details about their previous code if the solution does not meet their needs.

I recently deleted my Latex code for my dissertation and now I'm starting from scratch. In my last code I had a line of code at the beginning that does all of my auto fitting for brackets, fractions etc. without having to worry about using \Bigg etc. but I can't seem to remember what it is, I have been looking all over the internet but I can't find it. Someone help please.

If you just use \left( \right) and similarly for [ ], \{ \}, etc... then latex does the resizing for you. You don't need to write your own code for choosing the appropriate \big, \Big, \Bigg, etc...

If that's not what you mean, can you be more specific about what exactly your code did?
