How to increase the font in Yandex Browser on Android: all methods

Reading small text on a smartphone screen is a common problem, especially for users with visual impairments or when using high-resolution devices (Full HD+ or 4K). In the browser Yandex on Android the font size can be changed in several ways: from basic scaling settings to hidden parameters available through the engineering menu. However, not all methods are equally effective - some work only on certain models (Samsung Galaxy, Xiaomi Redmi), while others can distort the layout of sites.

In this article we will examine 5 proven methods increase the font in the Yandex Browser, including the settings of the application itself, Android system parameters and workarounds for stubborn sites. You will also learn why sometimes text appears too small even at maximum zoom, and how to fix it without losing image quality. All instructions are relevant for the latest versions of the browser (2026) and tested on devices with Android 12–15.

1. Enlarging the font through the Yandex Browser settings

The easiest way is to use the built-in scaling tools. Yandex Browser allows you to change the text size for all sites at once, as well as for specific pages.

To increase the font globally:

1. Open the browser and click on the icon «☰» (menu) in the lower right corner.
2. Select Settings → Appearance.
3. Find the item Font size and move the slider to the right (to 150% or 200%).
4. Restart the browser to make changes came into force.

For individual sites:

• 🔍 Open the desired page and double-tap the screen (gesture "zoom in").
• 📱 Use pinch (pinch/spread) to manually adjust the scale.
• 🔄 Click on the icon Aa in the address bar and select Enlarge text.

Reset browser cache in Settings → Privacy comparisons--> Settings → Privacy

Disable the option Adaptive scale for problematic sites

Try another browser (eg Chrome) for comparison -->

⚠️ Attention: On some sites (for example, VKontakte or Government services), forcing the font to increase can break the layout - buttons and menus will move off the screen. In this case, use system scaling (see section 3).

2. Changing the page scale through the engineering menu (for advanced)

If the standard settings do not help, you can use hidden parameters Android via engineering menu. This method works on most devices (Samsung, Xiaomi, Realme), but requires caution - incorrect changes can lead to failures.

Instructions:

1. Open the application Phone and enter the combination:

   ##4636##

   (on some devices this may be required ##36446337##).

2. In the menu that opens, select Phone information or Testing.
3. Find item WebView or Browser Settings.
4. Change settings Default zoom (default 100%) to 120%–150%.

After applying the changes, reboot device. This method affects the display of text in all browsers, including Yandex.

adb shell am start -n com.android.settings/.DevelopmentSettings

3. Android

If the problem is not only in Yandex Browser, but the text is small in all applications, it makes sense to change the system scaling settings. This method affects the display of fonts in Chrome, Telegram, WhatsApp and other apps.

How to increase the font at the system level:

1. Go to Settings → Screen (or Accessibility).
2. Select Font size or Screen scale.
3. Move the slider to the right (to 1.3x or 1.5x).
4. On some devices (Samsung, Huawei) an option is available Enlarged font —enable it.

For devices with Android 12+ a function is also available "Adaptive text" —it automatically adjusts the font size to the lighting and distance to screen. To activate it:

1. Open Settings → Accessibility → Vision.
2. Find Adaptive text and enable switch.
3. Adjust sensitivity manually or leave Auto.

⚠️ Attention: On devices with custom firmware (for example, LineageOS or Pixel Experience) system scaling may not work correctly - some interface elements will become too large or overlap each other. In this case, it is recommended to use only browser settings. data-i="175">4. Using extensions to force font changes.

4. Using extensions to force font changes

If the built-in tools do not work, you can install extensions that force changes to CSS styles on pages. For example, the extension «Custom CSS for Websites» allows you to set a fixed font size for any site.

How it works:

1. Install the extension from Chrome Web Store (it is compatible with Yandex Browser).
2. Open the site where you want to enlarge the text.
3. Click on the extension icon and add a rule:

   body {
   font-size: 18px !important;
   }

4. Save changes and refresh the page.

Alternative extensions:

• 🔧 Stylus —allows you to create custom styles for sites.
• 📏 Zoom Page WE —adds quick zoom buttons.
• 👓 High Contrast —increases contrast and text size for the visually impaired.

5. Workarounds for stubborn sites

Some resources (for example, Government services, SberBank Online or Avito) block zoom changes via viewport in the HTML code. In this case, reading mode or converting the page to PDF will help.

Ways to bypass restrictions:

• 📖 Reading mode: In Yandex Browser, open the menu (☰) and select Reading mode. The text will be displayed in a simplified form with the ability to enlarge.
• 📄 Save to PDF: Press ☰ → Share → Print → Save as PDF. You can zoom in the resulting file without restrictions.
• 🔄 Disable JavaScript: In browser settings (Settings → Privacy) disable JavaScript. Many sites will no longer block scaling, but some functions may not work.

On sites with responsive design (for example, YouTube or TikTok) forced font enlargement often breaks the layout - buttons and menus move out of place. In this case, it is better to use system scaling (section 3) or special applications for the visually impaired, for example Big Launcher.

6. Problems and their solutions

Even after changing the settings, users encounter typical problems. Here are the most common ones and how to fix them:

If none of the methods helped, check:

• 🔄 Version browser: Update Yandex Browser to the latest version in Google Play.
• 📱 Android version: Older firmware (Android 9 and below) may not have modern scaling options.
• 🛠️ Conflicts with other applications: Some launchers (for example, Nova Launcher) or apps to save battery may reset the font settings.
