Zoom in on the iPhone screen
In many apps, you can zoom in or out on specific items. For example, you can double-tap or pinch to look closer in Photos or expand webpage columns in Safari. You can also use the Zoom feature to magnify the screen no matter what you’re doing. You can magnify the entire screen (Full Screen Zoom) or magnify only part of the screen with a resizable lens (Window Zoom). And, you can use Zoom together with VoiceOver.
Set up Zoom
Go to Settings > General > Accessibility > Zoom, then turn on Zoom and do any of the following:
Track your selections, the text insertion point, and your typing: Turn on Follow Focus. Then, for example, if you use VoiceOver, the zoom window magnifies each element you select on the screen.
To magnify your typing (in Messages or Notes, for example) but not the keyboard, turn on Smart Typing.
Show the Zoom Controller: Turn on Show Controller. To adjust the transparency of the Zoom Controller when not in use, tap Idle Visibility, then drag the slider.
Choose the default Zoom region: Tap Zoom Region, then choose Full Screen Zoom or Window Zoom.
Apply a filter to the magnified part of the screen: Tap Zoom Filter, then choose Inverted, Grayscale, Grayscale Inverted, or Low Light.
Set the maximum magnification: Drag the Maximum Zoom Level slider.
To add Zoom to Accessibility Shortcut, go to Settings > General > Accessibility > Accessibility Shortcut, then tap Zoom.
Double-tap the screen with three fingers or use accessibility shortcuts to turn on Zoom.
