Change Android App Icon Size: Step-by-Step Guide

You can change the size of app icons on most Android phones by adjusting the home screen grid or using the display size setting, but the exact steps vary by phone manufacturer. This guide covers the common methods for stock Android, Samsung, Google Pixel, and other popular devices, plus how to use third-party launchers for more control.

Why Android Doesn’t Have a Single “Icon Size” Setting

Unlike iOS, Android is an open-source operating system with many manufacturers (Samsung, Google, Xiaomi, OnePlus, etc.) each using their own custom interface (called a “skin”). For example, Samsung uses One UI, Google uses Pixel UI, and Xiaomi uses MIUI. Each skin has its own settings menu, so there is no universal “app icon size” slider built into Android itself. Instead, you have to look for options like “Home screen grid,” “Display size,” or “Icon size” depending on your device.

Method 1: Change the Home Screen Grid (Most Common)

The most direct way to make icons smaller or larger is to change the number of rows and columns on your home screen. A 4×4 grid gives large icons; a 5×5 or 6×6 grid makes them smaller because they share the space.

1. Long-press on an empty area of your home screen (not on an icon).
2. Tap “Home screen settings” or “Settings” (the gear icon).
3. Look for “Home screen grid” or “App grid.”
4. Select a grid size (e.g., 4×5, 5×5, 6×6).

On Samsung phones, the path is: long-press home screen → Home screen settings → Home screen grid. On Google Pixel, you might not have a grid option in stock Android—instead, you can use the display size setting (see below).

Method 2: Use Display Size and Font Size Settings

Android has a global “Display size” setting that scales everything on the screen, including app icons. This is not the same as text size—it changes the overall zoom level.

1. Open Settings.
2. Tap Display (or “Display & brightness” on some devices).
3. Tap Display size (or “Screen zoom”).
4. Drag the slider left to make icons smaller, right to make them larger.

On Samsung, this is under Settings → Display → Display size and font size. On Pixel, it’s under Settings → Display → Display size. Note that this also affects text, status bar, and other UI elements, not just icons.

Method 3: Use a Third-Party Launcher (Most Flexible)

If your phone doesn’t have built-in icon size controls, or you want more precise adjustments, install a custom launcher. Launchers replace your home screen and offer granular icon size options. Popular ones include Nova Launcher, Apex Launcher, and Microsoft Launcher.

1. Install a launcher from the Google Play Store (e.g., Nova Launcher).
2. Open the launcher and set it as default (when you press the Home button, choose it).
3. Long-press on the home screen → Settings (or launcher settings).
4. Look for “Icon size” or “Icon layout”—usually under “Desktop” or “Home screen.”
5. Drag the slider or enter a specific size (e.g., 48dp, 52dp).

With Nova Launcher, you can also change the number of rows/columns independently of icon size, and even adjust label text size. This is the best way to get exactly the look you want.

Common Problems and Troubleshooting

• No grid option on my phone: Some stock Android devices (like Pixel) don’t have a home screen grid setting. Use the display size method or a launcher.
• Icons look blurry after resizing: This happens when you enlarge icons beyond their original resolution. Most icons are designed at 48×48 pixels, so increasing them too much causes blur. Try using a higher-resolution icon pack or keep the size close to default.
• Change doesn’t apply to all screens: Some settings only affect the main home screen, not the app drawer. Check if your launcher has a separate setting for the app drawer grid.
• Icons revert after restart: This is rare but can happen if you’re using a non-default launcher that crashes. Make sure you’ve set your launcher as the default in Settings → Apps → Default apps → Home app.

How to Choose the Right Icon Size

The best icon size depends on your screen resolution, personal preference, and accessibility needs. Here are some factors:

• Screen size and resolution: On a small screen (e.g., 5.5 inches), a 4×4 grid might be too large; a 5×5 grid often feels better. On a large tablet, you might want a 6×6 or even 8×8 grid.
• Vision: If you have difficulty seeing small icons, use a larger grid (fewer icons per screen) or increase display size.
• Number of apps: If you have many apps and want to see more at once, choose a denser grid (e.g., 6×6).
• Widgets: Larger icons take up more space, leaving less room for widgets. Plan your home screen layout accordingly.

Frequently Asked Questions

Why can’t I change icon size on my Samsung phone?

Samsung phones do allow icon size changes, but the option is hidden in the home screen settings, not in the main display settings. Long-press on the home screen, tap “Home screen settings,” then “Home screen grid.” You can also change the display size under Settings → Display, which affects icons too.

Will changing icon size affect app performance?

No, changing icon size only affects the visual appearance of the home screen. It does not change how apps run or their internal functionality. It may slightly affect battery life if you use a live wallpaper, but resizing icons itself has no performance impact.

Can I change icon size on Android without a launcher?

Yes, if your phone’s manufacturer provides the option. Many phones have a home screen grid setting or a display size setting that indirectly changes icon size. If not, you’ll need a third-party launcher.

Why do my icons look stretched after I change the grid?

Icons are designed to fit a certain grid size. When you change the grid, the launcher may stretch or compress icons to fill the cells. This is normal, but if they look distorted, try adjusting the icon size separately (if your launcher allows) or use a different grid that matches the icon’s aspect ratio.

Is there a way to change icon size on Android TV?

Android TV uses a different interface with a row-based layout. You cannot change icon sizes on Android TV’s default launcher. Some third-party launchers for Android TV exist, but they are limited. Generally, you’re stuck with the default size.
