You have to use the character ‘x’ instead of ‘*’ to indicate multiplication. This should work:

Try 265*125 config, because only certain configs work

Same, It says return'wm', 'geometry', self._w, newGeometry)
_tkinter.TclError: bad geometry specifier "300 x 250"

Hello @Marck,

You might have leave space in "300 x 250". This should be:


Also make sure X needs to be lowercased and make sure you import tkinter.

If above doesn't work share your code so that I can identify what is wrong in your code.

Hope it helps!!

Thank You!!
