I accidentally changed the font on my computer it way to big now and i cant change it back?

If "everything" is large then it has to be something with your display. You don't say what you checked in Display Properties. It also would help to know which OS you're using.

From what little info I read I'd say it's your DPI. It should be 'Normal size (96 DPI)'.

Assuming you are uding Vista. Vista is one of the operating systems used by Windows.

OS = operating system.

Right click on an open space of your desktop > click Personalize > left column, click "Adjust font size (DPI) " > you will be prompted to confirm the task by either entering your administrator password, or just clicking Yes or Continue > on your next windows click the circle in front of Default scale (96 DPI) - fit more information > click OK which is at the bottom.

Is it back to normal now ?

In computer field :

DPI = dots per inch.

1. control panel

2.Appearance and Personalization

3.fonts

4.on the left side of the screen it has a line that says change font size

it relatively is advantageous, no concerns. basically press CTRL then press - (minus sign) to make the font smaller, to make it super (which i think of you does not opt to do) basically press CTRL and + (plus sign) desire that helps!

Try going to "view" on your tabs and then click zoom. from there, zoom out.
