The size of the field controls only its physical image on the screen.  It
does not limit the amount of text which can be entered into the document
underneath.

Yes, if you must specify a size.  I avoid specifying sizes as much as possible
and rely upon layout managers to handle it.

When I want to do this, I set the text to 50 'M' characters, pack, and then
ask the component for its preferred size.  That's the size I use.  Generally
I do this when I want an input field to be blank at startup but sized
appropriately for typical inputs.
