If you want to increase (or even decrease) the size of the objects on your computer, in Windows XP, go to Start, Control Panel (make sure you’re in the classic view) and double click on the Display icon. Next, click on the Settings tab and then hit the Advanced button. Under the General tab, you can select which DPI setting you prefer. You can choose from Normal size, Large size or you can even make a Custom size just for you.
Once you choose your setting, you will be prompted to restart your computer. When it boots back up, you will be able to notice the size difference of the objects on your computer. Now, if you also want to change your font size, go back to StartControl Panel and click on the Display icon again. From there, click on the Appearance tab and then use the Font size drop down box to choose between Normal, Large or Extra Large. Then just hit OK and you’ll be all set. Your XP computer is now set up just the way you want it. Yes!
