Zooming the entire display on your iOS device (here’s how) is a handy way to give your eyes a break when it comes to tiny text, but it can be a little disconcerting when there’s nothing on your zoomed screen except for, say, a giant battery indicator.
Luckily, there’s another option if you want to zoom the display on your iPhone or iPad: putting a virtual magnifying glass on the screen.
The so-called “window zoom” mode for the iOS zoom feature puts a resizable window on the screen. Inside the window, the display is zoomed; outside, the screen is normal size. Dragging the window around the screen feels just like you’re using a magnifying glass.
Let’s Get Started
To get started, tap Settings, General, Accessibility, Zoom, then switch the main Zoom toggle on. If the entire screen suddenly zooms way in, don’t panic; just double-tap with three fingertips to go back to the normal view, or triple-tap with three fingertips to bring up the Zoom menu.
Next, scroll down to the Zoom Region setting, tap it, and select Window Zoom; when you do, a window showing a zoomed-in portion of the screen should appear. (If it doesn’t, try double-tapping the display with three fingertips again.)
To move the magnifying glass around the screen, just tap, hold, and drag one of the edges. To make the window bigger or smaller, triple-tap the screen with three fingertips to make the Zoom menu appear, tap the Resize Lens option, then drag the edges of the window to change its size and shape. When you’re done resizing, tap anywhere outside the window.
Want to change the magnification of the zoom? Double-tap anywhere on the screen with three fingertips, but hold your fingers on the screen on that second tap; then, just slide your three fingertips up to zoom in, or down to zoom out. If that doesn’t work, triple-tap with three fingertips, then use the magnification slider in the pop-up Zoom menu.
When you’re ready to make the magnifying glass disappear, double-tap with three fingertips anywhere on the screen. To get the magnifying glass back, just do the three-finger double-tap again.
