Many apps let you zoom in and out on specific items. For example, you can double-tap or pinch to expand webpage columns in Safari. But, there's also a Zoom feature that lets you magnify the entire screen, no matter what you're doing. And, you can use Zoom together with VoiceOver.

Turn Zoom on or off. Go to Settings > General > Accessibility > Zoom. Or use the Accessibility Shortcut-see Accessibility Shortcut.

Zoom in or out. Double-tap the screen with three fingers.

Verify the magnification. With three fingers, tap and drag up or down. The tap-and-drag gesture is similar to a double-tap, except you don't lift your fingers on the second tap - instead, drag your fingers on the screen. Once you start dragging, you can drag with a single finger. iPad returns to the adjusted magnification when you zoom out and in again using the three-finger double-tap.

Pan around the screen. While zoomed in, drag the screen with three fingers. Once you start dragging, you can continue with just one finger. Or, hold a single finger near the edge of the screen to pan to that side. Move your finger closer to the edge to man more quickly. When you open a new screen, Zoom goes to the top-middle of the screen.

While using Zoom with an Apple Wireless Keyboard, the screen image follows the insertion point, keeping it in the center of the display.
