I copied this from another tech support site (I don't recall which at the moment):
- Open a new Finder window.
- As you resize the window, hold the Command ⌘ (not Alt / Option) key. Close resized window.
- Then hold the Alt / Option key as you right click on Finder in the Dock and click Relaunch.
Any Finder windows opened after this will open at that size.
Note: This does not work for windows opened from folders on the desktop.
