To reduce screen size on iPhone 13, you cannot physically shrink the display, but you can use three built-in features, Reachability, Display Zoom, and Zoom, to make the screen easier to use with one hand or to make onscreen elements larger. These tools help you bring the top of the screen within thumb reach or magnify content, addressing the common need to reduce screen size iPhone 13 for better one-handed comfort.
Why making the screen easier to reach matters
Apple says Reachability lowers the top half of the screen so items are within thumb reach when using iPhone one-handed in portrait orientation. This improves comfort and reduces strain, especially during tasks like texting or browsing that require tapping the upper portion of the display. Reducing screen size can potentially extend battery life because a smaller screen means less power consumption. Reducing screen size can reduce eye strain during long browsing or gaming sessions. Display Zoom makes onscreen controls larger, which can help some users but does not reduce the physical screen size.
Method 1: Use Reachability to lower the top of the screen
Reachability is designed for one-handed use and works only in portrait orientation on iPhone 13 models.
- Go to Settings > Accessibility > Touch.
- Turn on Reachability.
- On an iPhone with Face ID, swipe down on the bottom edge of the screen to lower the top half.
- To return to full screen, tap the upper half of the screen.
To enable Reachability, the specific path is Settings > Accessibility > Touch > Reachability.
Method 2: Use Display Zoom to make everything larger
Display Zoom changes the overall scale of onscreen elements, making text and controls larger without altering the physical display.
- Go to Settings > Display & Brightness > Display Zoom.
- Select Larger Text to make all text larger.
- Tap Done, then tap Use Zoomed.
On some iOS versions, the path may appear as Settings > Display & Brightness > View and then Zoomed.
You can use Display Zoom and Reachability together to further optimize the screen size. Customize Font Size via Settings > Display & Brightness > Text Size to make text more readable without changing screen scale.
Method 3: Use Zoom to magnify part or all of the screen
Zoom is an accessibility feature that can magnify the entire screen or only a portion of it with a resizable lens.
- Go to Settings > Accessibility > Zoom.
- Turn on Zoom.
- Choose Zoom Region: Full Screen Zoom or Window Zoom.
- To use it, double-tap the screen with three fingers or use Accessibility Shortcut.
- To adjust magnification, double-tap with three fingers and drag up or down, or triple-tap with three fingers and use the Zoom Level slider.
- To turn it off, double-tap with three fingers or use Accessibility Shortcut.
iOS offers other accessibility features like Larger Text, Bold Text, and Zoom to further reduce effective screen size.

Frequently Asked Questions
Does iPhone 13 have a true screen shrink setting?
No. Apple does not provide a setting that physically reduces the screen size. The features described, Reachability, Display Zoom, and Zoom, adjust how content is displayed or accessed, not the actual screen dimensions.
Does reducing screen size affect resolution?
No. Using Reachability, Display Zoom, or Zoom does not change the native resolution of the iPhone 13 display. These features simply reposition or magnify content while maintaining the same pixel count.
How do I switch back to standard size?
To revert Display Zoom to standard, go to Settings > Display & Brightness > Display Zoom, select Standard, tap Done, then tap Use Standard. For Reachability, turn it off in Settings > Accessibility > Touch. For Zoom, turn it off in Settings > Accessibility > Zoom.
Can I use Reachability with Display Zoom at the same time?
