Material Symbols
The Next-Generation Variable Icon System from Google
Product Overview
Material Symbols is the latest-generation icon library, designed and maintained by Google as a major upgrade to the classic Material Icons. It not only adheres to the Material Design language but also innovatively introduces "Variable Font" technology, offering designers and developers an unprecedented level of customization. Revolutionary Variability: This is the core feature of Material Symbols. It packages all icons into a single variable font file and provides four adjustable "axes" for fine-tuning: Weight: Freely adjust the stroke thickness, from thin to bold. Fill: Control whether the icon is an outline or fully filled. Grade: Fine-tune the visual weight for optical balance against different backgrounds or at different sizes. Optical Size: Automatically optimizes the icon's details and clarity for different display sizes. Completely Free & Open Source: Google has made the entire Material Symbols library, including all its styles and variable features, available for free under the Apache 2.0 license, with no commercial restrictions. Perfectly Unified with the Google Ecosystem: As the official icon set for Material Design 3, it maintains perfect visual consistency with Android, Flutter, and various Google services, making it the best choice for building native-feeling experiences. Comprehensive Coverage with Three Styles: It offers thousands of icons covering the vast majority of use cases. In addition to the variable font version, it also comes in three distinct, pre-set styles: Outlined, Rounded, and Sharp. Material Symbols is no longer just a static collection of icons; it's a dynamic and highly adaptive "icon generation engine." Through variable font technology, it elevates the flexibility of icon design to a whole new dimension, enabling designers and developers to create the most visually harmonious and clear icons for any context with maximum efficiency.
