Suddenly everything become bigger

Suddenly everything become bigger and i cant change back to normal.Someone please help me because it just automatically change.

Two ways I use to change the view [only], one is to hold down the Ctrl key and press +/= or - key and hold down the Ctrl key and roll the mouse wheel back or forth. Might also check the Resolution setting for the display.

In addition, double check your DPI scaling level settings to make sure it's still set to the default 96 DPI (100%).
