React Native Font Family is a powerful tool that allows you to easily change the font used throughout your application. If you’re working with React Native, you may be wondering how to customize the font family on your app. By understanding the different font file formats and their compatibility, you can select a font family that will work seamlessly across all devices and platforms. However, it is important to note that some devices may have limited support for other font file formats, such as PostScript fonts (.ps), so be sure to check the compatibility of your chosen font before using it in your React Native project. Both formats are widely supported across various platforms and devices. The most commonly used formats are TrueType Font (.ttf) and OpenType Font (.otf). When using custom font families in React Native, it is important to understand the different font file formats available.
