What Is Android App Default Font?

When it comes to designing an Android app, choosing the right font is crucial. The default font used in an Android app plays a significant role in shaping the overall look and feel of the user interface. In this article, we will delve into the details of the default font used in Android apps, its characteristics, and how it can be customized.

The Default Font

In Android, the default font used across various devices is called Roboto. Roboto is a sans-serif typeface designed by Google specifically for use on Android devices. It was first introduced with Android 4.0 (Ice Cream Sandwich) and has since become the standard font for most Android applications.

Roboto offers a clean and modern appearance, making it suitable for a wide range of app designs. Its versatility allows it to adapt well to different screen sizes and resolutions, ensuring readability on both small smartphones and large tablets.

Characteristics of Roboto

The Roboto font family consists of several weights and styles that can be used to achieve different visual effects within an app:

  • Roboto Regular: This is the standard weight of Roboto and is commonly used for body text.
  • Roboto Bold: As the name suggests, this weight provides a bold appearance and can be employed to highlight important headings or key information.
  • Roboto Light: This weight is lighter than regular and can be utilized for captions or secondary text that requires less emphasis.

In addition to these weights, Roboto also includes italic versions for each weight, allowing for further customization of typography within an app.

Customizing the Default Font

While Roboto is the default font used in Android apps, it is not mandatory to stick to it. Developers have the freedom to choose alternative fonts that align with their app’s branding or design requirements.

To customize the default font, developers can utilize CSS (Cascading Style Sheets) in conjunction with HTML. By specifying a different font family in the CSS, developers can override the default Roboto font and replace it with any other compatible typeface.

For example, to change the default font to “Arial” for all paragraphs within an app, the following CSS code can be used:

    p {
      font-family: Arial, sans-serif;

This code snippet Targets all <p> elements and applies the “Arial” font. The fallback option of “sans-serif” ensures that if Arial is not available, a generic sans-serif font will be used instead.


The default font used in Android apps, Roboto, provides a clean and modern appearance suitable for most app designs. However, developers have the flexibility to customize the default font by utilizing CSS and specifying an alternative typeface that aligns with their app’s branding or design requirements.

By understanding the characteristics of Roboto and learning how to customize it, developers can create visually engaging Android apps that not only convey information effectively but also capture users’ attention through appealing typography.
