Small icons on a smartphone screen are a common problem, especially for users with visual impairments or owners of devices with high screen resolutions. Fortunately, Android offers several ways to enlarge application icons, most of them do not require root access or complex manipulations. In this article, we will analyze all the available methods: from standard launcher settings to hidden system parameters and even commands ADB for advanced users.

Not all methods are equally effective on different firmware. For example, on stock Android (pure Android from Google) icon scaling settings may be missing, while manufacturers like Samsung, Xiaomi or Huawei often add their own options. We will take these nuances into account and offer solutions for each situation.

If you have never changed the size of icons before, start with the first three methods - they are the safest and reversible. Advanced users can immediately go to the sections about ADB or third-party launchers, where there are much more opportunities for customization.

1. Changing the size of icons through the launcher settings

Most modern Android shells allow you to adjust the size of icons directly in the settings menu. This method works on Samsung One UI, MIUI, ColorOS and other proprietary firmware, but may not be available on bare Android (for example, on Pixel or Android One).

To check the availability of the option:

  1. Touch and hold an empty area on the desktop.
  2. In the menu that appears, select Screen settings (or Launcher settings, Home screen —the name depends on the firmware).
  3. Look for items like Icon Size, Screen Layout or App Grid.

For example, in One UI (Samsung) the path looks like this: Settings → Home screen → Layout → Icon size. There are 3-5 preliminary scale options available. In MIUI (Xiaomi) a similar option is hidden in Themes → Icon settings.

⚠️ Attention: On some devices, changing the size of icons automatically reduces the number of rows/columns on the screen. If it is important for you to maintain the current layout, take a screenshot of the icon layout in advance.

If your firmware does not have such an option, do not despair - go ahead. to the next method.

2. Increasing the scale of the entire interface (Display Size)

Android has a built-in scaling function the entire interface, including icons, fonts and controls. This is a universal method that works on any device, but has a side effect: along with the icons, other elements will increase. system.

How to change the scale:

  1. Open Settings → System → Gestures and movements → Size display (on some devices the path may differ: Settings → Screen → Font and display size).
  2. Move the slider to the right to increase the scale. We recommend starting with a minimal change (for example, +10%) and check the convenience.
  3. Click Apply and confirm the changes.

This method is especially useful for devices with large screens (for example, Samsung Galaxy Tab or Xiaomi Pad), where small icons are difficult to press with your finger. However, please note that some applications (for example, games or banking). services) may not be displayed correctly at a non-standard scale.

💡

If, after changing the scale, some applications look blurry, try disabling the "Scale to fit screen" option in their settings (if there is one).

3. Using third-party launchers for fine tuning

If the standard settings do not suit you, the best solution is install third-party launcher. Popular options like Nova Launcher, Apex Launcher or Microsoft Launcher offer flexible settings for the size of icons, the space between them and even the shape of icons.

Consider setting on example Nova Launcher (the most functional option):

  1. Install the launcher from Google Play and make it the default launcher.
  2. Touch and hold an empty area on the desktop, then select Settings.
  3. Go to Home screen → Icon size and move the slider to the desired value (from 50% to 150%).
  4. In section Layout You can further adjust the number of rows/columns and indents.

Advantages of third-party launchers:

  • 🎨 Fine-tuning the size of icons (in increments of 5–10%).
  • 📱 Ability to change the shape of icons (round, square, adaptive).
  • 🔄 Flexible control of the desktop layout (for example, 5×6 instead of the standard 4×5).
  • 🔒 Saving settings when changing devices (via backup).
⚠️ Attention: Some launchers (for example Nova Launcher Prime) require the purchase of a premium version to unlock all zoom functions. The free version usually limits the range of changes.

4. Editing icons via ADB (for advanced)

If you need change the size of system application icons or bypass firmware limitations, you can use the commands ADB (Android Debug Bridge). This method requires connecting the device to a computer and basic knowledge of working with a terminal.

Step-by-step guide:

  1. Enable USB Debugging on your phone: Settings → About phone → Build number (press 7 times to unlock developer mode), then return to Settings → System → For Developers → USB Debugging.
  2. Connect your phone to the PC and confirm trust in the computer.
  3. Open Command Prompt (Windows) or Terminal (macOS/Linux) and enter: 
    adb shell settings put global icon_scale_factor 1.3

    Here 1.3 —scale factor (1.0 = standard size, 1.5 = 50% increase).

  4. Reboot the device for the changes to take effect.

Acceptable coefficient values: from 0.8 (decrease) to 1.5 (increase). Exceeding these limits may lead to failures in the interface display.

To return the standard size, run the command: 

adb shell settings put global icon_scale_factor 1.0
What to do if ADB does not recognize the device?

Make sure that the drivers for your smartphone are installed (download them from the manufacturer's website).

Try using a different USB cable (preferably the original one).

Enable the "Allow USB debugging (safe mode)" option in the developer settings.

Restart your phone and PC, then reconnect.

5. Setting the size of icons in the application menu

Many users forget that the size of icons on desktop and application menu (app drawer) are adjusted separately. If you need to enlarge the icons only in the list of all apps, look for the corresponding option in the launcher settings.

Examples for popular shells:

Firmware/Launcher Path to settings Available options
One UI (Samsung) Settings → Home screen → Application menu → View List/Grid, icon size, sorting
MIUI (Xiaomi) Themes → Icon settings → Application menu Icon size, padding, animation
Nova Launcher Settings → Application menu → Icon size Scale 50–150%, customize rows/columns
Stock Android (Pixel) No built-in options Requires a third-party launcher

On some devices (for example Huawei EMUI), the application menu may does not support resizing icons. In this case, only replacing the launcher or using ADB-commands from the previous section will help.

6. Accessibility: Magnification for the Visually Impaired

If you need to enlarge icons due to vision problems, please take a look at accessibility settings. Android offers several tools that can help:

Where to find these options:

  • 🔍 Settings → Accessibility → Zoom - here you can enable Zoom gesture (triple tap to zoom screen).
  • 📱 Settings → Accessibility → Size and text —options for changing the scale of fonts and interface elements.
  • 🎯 Settings → Accessibility → Contrast colors —improves the visibility of icons by changing color scheme.

For maximum effect, combine these settings with changing the icon size through the launcher. For example, you can enlarge icons by 30% and at the same time activate Zoom gesture to view fine details in detail.

💡

Accessibility settings apply to the entire interface, not just icons. This can be useful for users with severe vision problems, but is less convenient if you only need to change the size of the icons.

7. Problems and solutions: why icons do not change size

Sometimes users are faced with the fact that icon size settings are not applied or do not work correctly. Let's look at typical causes and ways to eliminate them:

Frequent problems and solutions:

  • 🔄 Settings are not saved: Restart the device or clear the launcher cache (Settings → Applications → Launcher → Memory → Clear cache).
  • 📵 The option is not in the firmware: Install a third-party launcher (see section 3) or use ADB (section 4).
  • 🖼️ Icons become blurry: This is due to the stretching of low-quality icons. Try installing a high-resolution icon pack (for example Whicons or CandyCons).
  • 🔒 System applications do not change size: They may require ADB or root access.

If none of the methods worked, check:

  1. Is your device's firmware updated to the latest version.
  2. Are there any conflicts with other applications (for example, themes or modules Magisk).
  3. Are there performance limits set (for example, in MIUI there is a "Battery and Performance" function that can block interface changes).
⚠️ Attention: On some devices (for example Oppo ColorOS or Realme UI), changes in icon size may be reset after updating the firmware. using ADB or create backup copies of the launcher configuration.

FAQ: Frequently asked questions about resizing icons

Is it possible to enlarge icons only on the desktop without affecting the application menu?

Yes, in most launchers (including standard ones) Icon size settings for the desktop and application menu are separated. For example, in Nova Launcher these are two different parameters: Icon size (home screen) and Icon size (application menu).

Why did they become blurry after enlarging the icons?

This is due to the fact that the system stretches standard low-resolution icons. Solutions:

  • Install a pack of high-quality icons (for example, Pixel Icon Pack or Lines).
  • Use a launcher that supports adaptive icons (for example, Nova Launcher or Action Launcher).
  • Reduce the zoom factor to 120–130% (higher magnification increases blur).

How to return the standard icon size after experiments?

Methods depend on the method of change:

  • If you used the launcher settings: return the slider to the default position or reset the launcher settings.
  • If you used ADB: run the command adb shell settings put global icon_scale_factor 1.0.
  • If you installed a third-party launcher: delete it or reset the settings in the launcher menu.

Rebooting the device will speed up the application of the changes.

Will enlarging the icons affect the performance of the smartphone?

No, changing the size of the icons does not load the processor or RAM. However, using third-party launchers with. animations and additional effects may slightly increase battery consumption (by 1–3%).

Is it possible to change the size of icons only for individual applications?

In the standard Android settings there is no such option. However, some launchers (for example, Nova Launcher with a plugin TeslaUnread) allow it. customize notifications and badge icons for individual applications, which visually changes their perception. For complete customization, you will need root access and manual editing of files .apk.
