How to Zoom on iPhone with iOS 17

Before we dive into the steps, it’s crucial to understand that zooming on an iPhone can refer to two different actions: magnifying the entire screen or just enlarging content like photos and web pages. Both are useful and straightforward.

Step 1: Enable Zoom in Settings

Go to Settings, select Accessibility, then Zoom, and toggle it on.
Enabling Zoom in the settings allows you to use this feature throughout the whole system, not just in certain apps. It’s especially handy when you need larger text across all functions of your iPhone.

Step 2: Use the Zoom Gesture

Double-tap with three fingers to activate the Zoom function.
Once Zoom is enabled, you can quickly magnify the screen at any time. This gesture is intuitive and becomes second nature after a bit of practice.

Step 3: Adjust Magnification

Drag three fingers up or down to adjust the zoom level.
After double-tapping to zoom in, you might want to tweak the magnification level. Sliding three fingers allows for precise control, ensuring the content is just the right size for your needs.

Step 4: Pan Around the Screen

Move around the screen with three fingers to view different areas.
When zoomed in, you won’t be able to see the entire screen at once. Panning with three fingers lets you explore different parts of the display effortlessly.

Step 5: Zoom Out

Double-tap with three fingers to zoom out and return to the normal view.
After you’re done examining details, a quick double-tap gesture will take you back to the regular screen view.

Attention to DetailWhether you’re editing photos or reading fine print, zoom allows you to see details you might otherwise miss.
FlexibilityYou can zoom in on specific apps, like Photos, or across the entire system, giving you control over how you view content.


Battery DrainUsing the zoom function frequently can consume more battery life as the phone works harder to render the magnified content.

Gesture Learning CurveIt may take time for some users to get used to the three-finger gestures required for zooming in and out.

Additional Information

When using zoom on your iPhone running iOS 17, it’s important to remember a few extra tips. For instance, did you know that you can adjust the zoom level in Settings for more granular control? That’s right, besides using the three-finger drag gesture, you can specify the exact magnification percentage you prefer. Also, there’s a feature called Smart Typing that automatically zooms out when you need to type, making it easier to see the keyboard.

And for those who might find the three-finger tap challenging, there’s an option to use a controller. This on-screen joystick lets you pan around and adjust zoom without the gestures. Lastly, remember that zoom settings can be tweaked to your preferences, so explore the options and customize the experience to fit your needs.
