Zoom
Many iPhone apps let you zoom in or out on specific elements. For example, you can
double-tap or use the pinch gesture to expand webpage columns in Safari.
Zoom is also a special accessibility feature that lets you magnify the entire screen of
any app you’re using, to help you see what’s on the display.
Turn Zoom on or off: In Settings, choose General > Accessibility > Zoom and tap the
Zoom On/Off switch.
Note: You can’t use VoiceOver and Zoom at the same time.
Zoom in or out: Double-tap the screen with three fingers. By default, the screen is
magnified 200 percent. If you manually change the magnification (by using the tap-
and-drag gesture, described below), iPhone automatically returns to that magnification
when you zoom in by double-tapping with three fingers.
Increase magnification: With three fingers, tap and drag toward the top of the
screen (to increase magnification) or toward the bottom of the screen (to decrease
magnification). 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.
Move around the screen: When zoomed in, drag or flick the screen with three fingers.
Once you start dragging, you can drag with a single finger so that you can see more
of the screen. Hold a single finger near the edge of the display to pan to that side of
the screen image. Move your finger closer to the edge to pan more quickly. When you
open a new screen, Zoom always goes to the top-middle of the screen.
While using Zoom with an Apple Wireless Keyboard (see “Using an Apple Wireless
Keyboard” on page 40), the screen image follows the insertion point, keeping it in the
center of the display.
Large Text
Large Text lets you make the text larger in alerts, and in Calendar, Contacts, Mail,
Messages, and Notes. You can choose 20-point, 24-point, 32-point, 40-point, 48-point,
or 56-point text.
Set the text size: In Settings, choose General > Accessibility, tap Large Text, then tap
the text size you want.
