The frame.

If you say
M-x tool-bar-mode RET

4 times in a row, you end up with the same size frame as before?
Guess you are lucky then.

Nonsense.

You don't see the frame size change at all?  Then you must have a
particularly lucky relation between toolbar height and font size, or
your toolkit behaves different from mine (GTK+).
