How to Increase The Size of Screen Text and Images

Whether you want to temporarily or permanently increase the size of items on your screen, your operating system will help you see the text and images more clearly. Both Mac and Windows computers feature quick zoom keyboard shortcuts to increase and decrease size. The Windows 7 Accessibility Center features a magnifier for larger text and images, or you can change your screen resolution to make items larger by default. Mac OS X has a program called Zoom to increase text and image size.
