You can change app icon size in two ways: using the Home Screen grid settings or by creating custom app stacks
iPhone gives you two main ways to adjust how large your app icons appear. The first is built into Settings and changes the grid layout of your entire home screen — this makes all icons uniformly larger or smaller. The second method uses App Library stacks to group apps and display them at different sizes. Which one you choose depends on whether you want to resize everything at once or just certain apps.
Neither method requires downloading anything or restarting your phone. Both work on any iPhone running iOS 14 or later.
Key Takeaways
- The Home Screen grid setting in Display & Brightness lets you switch between standard and larger icon layouts, affecting all apps at once.
- You can manually resize individual apps by dragging them into stacks or folders, which display at smaller sizes than home screen icons.
- Creating custom App Library folders groups related apps and lets you control how many appear in a single space.
- Zooming in on your entire screen through Accessibility settings makes icons larger but also enlarges text and buttons across all apps.
Changing the home screen grid to make all icons larger
Open Settings, then tap Display & Brightness. Scroll down and look for the option labeled "Text Size" or "Display Zoom" depending on your iOS version. Some iPhones show a "Larger Accessibility Sizes" toggle instead. Tap whichever option appears, and you will see two preview images — one showing the standard grid and one showing a larger grid layout.
Select the larger option and tap Set. Your home screen will immediately reorganize, and all app icons will become noticeably bigger. This change affects only your home screen layout, not the icons inside folders or the App Library. If you want to undo this, return to the same menu and select Standard.
This method works best if you want uniform sizing across all your apps. The trade-off is that fewer icons fit on each screen, so you may need to swipe through more pages to find what you want.
Making individual apps smaller by grouping them
To make specific apps appear smaller without changing your entire home screen, create a folder or stack. Press and hold any app icon until a menu appears, then tap "Add to Home Screen" or drag the app onto another app icon. This creates a folder containing both apps, and the folder displays as a single icon with a smaller preview of the apps inside.
You can add up to nine apps per folder. The folder icon shows a grid of the app logos at reduced size, making them visually smaller than standalone home screen icons. Tap the folder to open it and see all apps at normal size, or swipe through the folder pages without opening it by swiping left and right on the folder icon itself.
This approach is useful if you have apps you use less often and want to save home screen space while keeping them organized by category — for example, a folder for games, one for productivity, and one for utilities.
Using App Library to organize apps into automatic categories
Swipe to the far right of your home screen to reach the App Library, which automatically sorts all your installed apps into categories like Productivity, Entertainment, and Utilities. Each category appears as a single icon showing a preview of apps inside. Tap any category icon to see all apps in that group.
You cannot manually resize App Library icons the way you can home screen icons, but the App Library itself takes up less visual space because multiple apps are represented by single category icons. This is a good way to keep your home screen clean and uncluttered while still having quick access to all your apps.
If you want to remove an app from your home screen entirely and keep it only in the App Library, press and hold the app, tap "Remove from Home Screen," then confirm. The app stays installed and searchable but no longer takes up home screen real estate.
Using accessibility zoom to enlarge everything on screen
If you need apps and text to be larger for visibility reasons, go to Settings, tap Accessibility, then tap Zoom. Turn on the Zoom toggle. You can then pinch and zoom on your screen to magnify the entire display, including app icons, text, and buttons.
This method enlarges everything proportionally, not just app icons. It is most useful if you have vision concerns and need larger text and interface elements across all apps, not just on the home screen. The zoom level persists across your phone, so you can set it once and it stays active.
Be aware that zooming in reduces how much content fits on screen at once, so you may need to scroll more to see full pages or lists.
What happens to app icons inside folders and the App Library
When you open a folder, the apps inside always display at their standard size regardless of your home screen grid setting. The folder itself may be smaller or larger depending on your grid choice, but the contents stay consistent. Similarly, apps in the App Library display at a fixed size when you open a category.
This means if you want smaller icons overall, folders and the App Library are your best options. If you want larger icons, the home screen grid setting is the most straightforward approach. You can combine both methods — use the larger grid for your main home screen and organize less-used apps into folders to save space.
Frequently Asked Questions
Can I make some apps bigger and others smaller on the same home screen?
Not directly through a single setting. Your home screen grid applies to all icons uniformly. However, you can create folders for apps you want to appear smaller, which will sit alongside your larger home screen icons. This gives the visual effect of mixed sizes.
Does changing icon size affect how apps work or how fast they run?
No. Resizing icons is purely visual and does not change app performance, storage use, or functionality. Apps run exactly the same regardless of how large their icons appear on your home screen.
What if I change the grid size and some apps disappear from my home screen?
They have not disappeared — they have moved to additional home screen pages because fewer icons fit per page with the larger grid. Swipe left to find them, or use Spotlight search by swiping down from the top of the screen and typing the app name.
Can I resize icons in the App Library?
No. App Library category icons are a fixed size and cannot be resized. You can only control the size of icons on your home screen through the grid setting or by organizing them into folders.
If I use zoom accessibility, does it affect how other people see my phone?
No. Zoom is a personal setting tied to your account. If someone else uses your phone with their own login, they will see the standard zoom level unless they also enable zoom in their accessibility settings.
