Overview

What Material Design 3 is

Material Design 3, commonly called Material 3, is the latest major version of Google's open-source design system. It provides guidelines, components, and design tokens for building coherent, accessible user interfaces across Android, the web, and Flutter.

Material 3 launched in 2021 with Android 12 under the Material You banner, emphasizing personalization. In May 2025 Google introduced Material 3 Expressive, a refresh centered on more emotive motion, updated shapes, refreshed color roles, and more impactful typography, which began rolling out to Pixel devices with Android 16.

How Material Design 3 works

Material 3 organizes styling into design tokens for color, typography, shape, and elevation, so values can be changed centrally and applied consistently. Its signature feature, dynamic color, generates a full palette from a source such as the user's wallpaper, giving each device a personalized yet accessible theme.

Google publishes Material 3 component libraries and Figma design kits, plus native implementations in Jetpack Compose for Android and in Flutter. The system builds in accessibility considerations such as contrast and touch-target sizing as part of its component specs.

Why Material Design 3 matters

Following an established design system speeds up development, keeps products visually consistent, and inherits accessibility work that Google has already validated. For Android and Flutter teams, Material 3 is the default, well-documented styling foundation.

Material 3 Expressive signals a shift toward more distinctive, personality-driven interfaces. Teams should note that it is an evolving standard, and that a fully custom brand system may be preferable when a product needs to look clearly different from stock Google styling.
