How can the 'Open File...' dialog window be made larger, by default?

How do I make this window larger by default so whenever I use 'open a file' in any program, it's not super small?

I am referring to the window size, not the text size.

I have the Finder (outside of 'open a file') larger by default, but I am unsure how to make this one larger.

Solution 1:

Generally speaking a window remembers the last size it was set to before closing it. That can and will be overridden on an individual folder basis. EG a folder will usually remember the size and position of the finder window that was opened to view it.

Unfortunately the days of a truly spatial Finder went away with macOS X. So the Mac does not always remember the window size, icon arrangement and such. A feature I really miss from the Classic MacOS days.

But, again, macOS should remember the size that the last Finder window that was opened.
