How to Make Apps Bigger on iPhone

To make apps bigger on an iPhone, open Settings, tap Display & Brightness (Appearance in iOS 27), tap Display Zoom, choose Larger Text, and confirm with Use Zoomed. Icons, text, and buttons all get bigger. If you only want bigger Home Screen icons, touch and hold the Home Screen background, tap Edit, tap Customize, and pick the large icon size instead.

“Bigger apps” can mean four different things: bigger icons, a bigger version of everything on screen, bigger text inside apps, or a quick zoom on one small detail. The iPhone has a separate setting for each, and none of them needs an extra app. This guide walks through every option, tells you which iOS versions use which menu names, and shows how to undo each change.

Which method should you use?

Pick the row that matches what you want to change. Each method has its own section below.

What you want	Use this	What changes
Everything bigger, in every app	Display Zoom	Icons, text, buttons, and the keyboard
Bigger Home Screen icons only	Large icon size (iOS 18 or later)	App icons; app names are hidden
One app to stand out	A widget made from the app icon	That one app takes more space and shows more
Bigger words inside apps	Text Size or Larger Text	Text in apps that support it
Bigger text in one app only	Per-App Settings	Only the app you add
A closer look for a moment	Zoom	Nothing permanent; you magnify on demand

What you need before you start

• Your iOS version. Open Settings > General > About to see it. Menu names moved between versions, so this tells you which steps to follow.
• iOS 18 or later for large icons. Apple added the large Home Screen icon size in iOS 18. Display Zoom, Text Size, and Zoom are available on older versions too.
• A supported model for Display Zoom. Apple says Display Zoom works “on supported models” and does not publish a single list in the user guide. If you do not see the option, your iPhone may not offer it.
• A minute to rearrange. Bigger items take more room. Expect a few icons to shift after you change the size.

Not sure where the Settings app went? Here is how to find the Settings app.

Method 1: Turn on Display Zoom to make everything bigger

Display Zoom is the closest thing to a “make all my apps bigger” switch. It magnifies the whole screen, so icons, text, buttons, and menus all grow together. These steps follow Apple’s guide, Adjust iPhone display and text settings.

Before you confirm: the screen changes layout right away. Fewer items fit on each screen, and some Home Screen icons may move to another page. Nothing is deleted, and you can switch back at any time.

iOS 27

1. Open Settings.
2. Tap Appearance.
3. Tap Display Zoom.
4. Tap Larger Text. A preview shows how the screen will look.
5. Tap the confirm button at the top of the screen, then tap Use Zoomed.

iOS 17, iOS 18, and iOS 26

1. Open Settings.
2. Tap Display & Brightness.
3. Scroll down and tap Display Zoom.
4. Tap Larger Text.
5. Tap Done (a confirm button in iOS 26), then tap Use Zoomed.

iOS 15 and earlier

The setting is in the same place but uses different words. Go to Settings > Display & Brightness, tap View below Display Zoom, select Zoomed, then tap Set. On iOS 16, follow whichever set of labels your screen shows.

What to expect: the screen may go dark for a moment while the iPhone applies the new size. When it comes back, icons and text are larger everywhere, including inside third-party apps.

To undo it: go back to Display Zoom and choose Default (called Standard on iOS 15 and earlier), then confirm.

Method 2: Use the large icon size on the Home Screen

If the text in your apps is fine and you only want bigger icons to tap, use the large icon size. It was added in iOS 18 and does not change anything inside your apps. Apple covers it in Customize apps and widgets on the iPhone Home Screen.

Know this first: Apple notes that in the large size, the names of the apps disappear. You will need to recognize apps by their icons alone.

1. Go to the Home Screen.
2. Touch and hold an empty part of the Home Screen background until the icons begin to jiggle.
3. Tap Edit at the top of the screen, then choose Customize. A small panel opens at the bottom.
4. Tap the large icon size. In iOS 18 it is labeled Large; in newer versions it is a button with a size symbol.
5. Tap an empty area of the Home Screen to close the panel.

What to expect: every icon grows and the labels under them vanish. The same panel also holds the Dark, Tinted, and (in newer versions) Clear looks, which change color and not size.

To undo it: open Edit > Customize again and tap the small size. The app names come back.

If you forget which icon is which without the names, swipe down on the Home Screen and type the app name in Search.

Method 3: Turn one app into a bigger widget

You cannot enlarge a single app icon by itself. What you can do, on recent versions of iOS, is turn that app’s icon into a widget. A widget is a larger tile that shows live information from the app, such as the forecast or your next calendar event, and opens the app when you tap it.

1. Touch and hold the app icon on the Home Screen.
2. Look at the row of small size icons at the bottom of the pop-up menu.
3. Tap the size you want. The icon expands into a widget of that size.

Apple notes that not all apps offer every widget size. Some provide only small and medium widgets, while others go up to extra large. If you see no size icons in the menu, that app does not offer a widget.

To undo it: touch and hold the widget, then tap the app icon button in the same row to shrink it back. Apple describes both directions in Add, edit, and remove widgets on iPhone. For a worked example, see how to add a weather widget to your iPhone Home Screen.

Method 4: Make the text inside apps bigger

Often the icons are fine and the real problem is small words in Mail, Messages, or Settings. In that case change the text size and leave the icons alone.

Set one text size for all apps

1. Open Settings.
2. Tap Display & Brightness (or Appearance in iOS 27).
3. Tap Text Size.
4. Drag the slider to the right. The sample text grows as you drag.

In the same menu you can turn on Bold Text to make letters heavier.

Go beyond the normal maximum

1. Open Settings > Accessibility > Display & Text Size.
2. Tap Larger Text.
3. Turn on Larger Accessibility Sizes.
4. Drag the slider to the right for the extra sizes.

This setting only affects apps that support it. Apple lists Calendar, Mail, Messages, Notes, and Settings as examples. Apps that draw their own text, such as many games, may ignore it. For those, use Display Zoom or Zoom. Apple’s page Make text easier to read on iPhone has the full details, and our guide on how to make text bigger on iPhone goes deeper on this one setting.

Change text size without leaving the app

Apple’s tip: open Control Center and use the Text Size slider. If the slider is not there, tap the edit button in the top-left corner of Control Center, tap Add a Control, then tap the Text Size control. After that, you can adjust the size while you are looking at the text you want to read.

Method 5: Make one specific app bigger with Per-App Settings

If only one app is hard to read, you do not have to change the whole phone. Per-App Settings lets you choose different text size, color, and motion settings for certain apps, or for the Home Screen and App Library.

1. Open Settings > Accessibility.
2. Scroll down and tap Per-App Settings.
3. Tap Add App, then choose the app from the list. You can also choose Home Screen & App Library.
4. Tap the name of the app you just added to open its settings.
5. Change the text size options for that app, such as Larger Text or Bold Text.

The rest of the phone keeps its normal size. To undo the change, return to Per-App Settings and set the option back to its default, or remove the app from the list. Apple documents the feature in Customize visual accessibility settings for specific apps on iPhone. Per-App Settings changes text and display options; it does not enlarge the app’s icon.

Safari has its own control as well. Tap the Page Menu button on the left side of the search field, tap Page Zoom, then tap the large A to enlarge the page. See how to zoom in or out on web pages in Safari for more.

Method 6: Zoom in only when you need to

Zoom is an accessibility feature that magnifies the screen on demand. It is separate from Display Zoom: nothing changes until you use a gesture, and one more gesture puts everything back.

1. Open Settings > Accessibility > Zoom.
2. Turn on Zoom.
3. Double-tap the screen with three fingers to zoom in.
4. Drag with three fingers to move around the magnified screen.
5. Double-tap with three fingers again to zoom back out.

To change how strong the magnification is, double-tap with three fingers without lifting them after the second tap, then drag up or down. In the Zoom settings, Zoom Region lets you choose Full Screen Zoom or Window Zoom, which magnifies only part of the screen inside a movable lens. Maximum Zoom Level sets how far you can zoom in. Apple explains every option in Zoom in on the iPhone screen, and we cover the limit in how to use Zoom and change the maximum zoom level on iPhone.

If the whole screen suddenly looks huge and you did not mean to do it, Zoom is the usual cause. Double-tap with three fingers to return to normal.

How to confirm the change worked

• Display Zoom: go back to the Display Zoom screen. Larger Text is selected, and the Home Screen shows bigger icons with less room around them.
• Large icons: the names under your Home Screen icons are gone.
• Widget: the app takes up the space of several icons and shows information inside the tile.
• Text Size: open Settings or Messages. Supported apps show the new size right away.
• Per-App Settings: open the app you added and compare it with one you did not.

Troubleshooting

There is no Display & Brightness menu

In iOS 27, Apple’s user guide lists Text Size, Bold Text, and Display Zoom under Settings > Appearance. If you cannot find either name, pull down on the main Settings screen and type “Display Zoom” in the search field.

Display Zoom is not listed

Apple says the feature is available on supported models, so some iPhones do not show it. Use Text Size, Larger Accessibility Sizes, or Zoom instead; those do not depend on Display Zoom.

Customize does not show a size option

The large icon size needs iOS 18 or later. Check your version in Settings > General > About. On older versions, Display Zoom is the way to get bigger icons. Also make sure you touched and held the Home Screen background and not an app, because holding an app opens that app’s own menu.

Text is bigger in some apps but not others

Text Size and Larger Text only work in apps that support them. For an app that ignores the setting, turn on Display Zoom, use Zoom, or look for a font size option inside that app’s own settings.

Icons moved or the Home Screen looks crowded

Bigger items leave less room, so the iPhone may push icons to another page. Touch and hold the background and drag icons where you want them, group them into folders, or delete apps you no longer use.

Text is cut off after increasing the size

Very large accessibility sizes can run out of room in some screens. Lower the slider a step or two, or keep a moderate text size and add Display Zoom on top.

Frequently Asked Questions

Can I make just one app icon bigger on iPhone?

No. The large icon size applies to every icon at once. To make one app stand out, touch and hold its icon and choose a widget size, if the app offers widgets. To make the content inside one app bigger, add that app in Settings > Accessibility > Per-App Settings.

What is the difference between Display Zoom and Zoom?

Display Zoom is a setting that keeps everything on the iPhone larger all the time until you turn it off. Zoom is an accessibility feature that magnifies the screen only when you double-tap with three fingers, and returns to normal when you do it again.

Why did my app names disappear?

The large Home Screen icon size hides app names. Apple states this in its Home Screen guide. Touch and hold the Home Screen background, tap Edit > Customize, and choose the small size to bring the names back.

Does Display Zoom delete or rearrange my apps?

It does not delete anything. Because each item is larger, fewer fit on a screen, so some icons can move to a different Home Screen page. Switching back to Default restores the original size.

Can I use Display Zoom and larger text together?

Yes. They are separate settings, and Apple suggests the Accessibility text options as a next step if Display Zoom alone is not enough. Start with Display Zoom, then raise Text Size until reading is comfortable.

How do I make apps smaller again?

Reverse whichever setting you changed: choose Default in Display Zoom, pick the small icon size in Edit > Customize, drag the Text Size slider back to the left, or double-tap with three fingers to leave Zoom.

Is it the same on an iPad?

Not exactly. The iPad has its own Home Screen and text settings with different menu names. See how to make text and apps bigger on iPad.

Next step

Start with Display Zoom, since it is the one change that makes every app bigger at once. If that is more than you need, switch it back to Default and try the large icon size or Text Size on its own. Each setting can be undone in a few taps, so you can try them one at a time until the screen is comfortable.
