How Google and Apple Design for Billions of Users: Lessons from Design Systems
Google has more than 200 products — Gmail, Maps, YouTube, Drive, Photos, Calendar — and all of them need to feel like they come from the same company. Apple has iOS, macOS, watchOS, tvOS — different operating systems, yet all of them need to feel like "Apple."
How do they do it? The answer is Design Systems.
What Is a Design System?
A Design System is a collection of rules, components, and patterns that ensures anyone in the company who designs or develops produces a consistent result.
It is not just colors and fonts. A complete Design System includes:
- Ready-made components (Buttons, Cards, Navigation bars)
- Usage guidelines (When to use each component)
- Interaction patterns (How things move and respond)
- Design principles (The values that guide decisions)
- Production-ready code (Components implemented programmatically)
Material Design: Google's Philosophy
Google launched Material Design in 2014, and it is not just a style guide — it is a complete design philosophy.
The Core Principle: Digital Material
Material Design is built on the idea that digital elements behave like real materials — they have thickness, they cast shadows, they move naturally. A card rises above the background, a button is pressed and bounces back, and a menu appears from a specific location.
The Elevation System
Rather than letting every designer decide how much shadow to use, Google created a defined elevation system — from 0dp to 24dp. Each component has a fixed elevation. The app bar sits at 4, the FAB at 6, and the dialog at 24. This ensures visual hierarchy is consistent across all products.
The Motion Guidelines
Motion in Material Design is not random. Every animation follows rules:
- Elements appear from the point where the user tapped
- Movement is fast and natural — not slow and tedious
- Related elements move together
Material Design 3
In 2021, Google launched Material Design 3 (Material You) — and added a brilliant feature: Dynamic Color. The system extracts colors from the phone's wallpaper and builds a complete color palette for applications. This gives every user a unique yet cohesive experience.
Human Interface Guidelines: Apple's Philosophy
Apple has its own system — the Human Interface Guidelines (HIG). Its philosophy differs from Google's.
The Core Principle: Clarity, Deference, and Depth
Apple focuses on three values:
- Clarity: Everything is clear and legible
- Deference: The design serves the content, not competing with it
- Depth: Layers and motion create a sense of depth
Attention to Detail
Apple is known for specifying every detail. Icon sizes must be exactly 29×29 or 60×60. The padding between elements has specific values. Even corner radius has rules — using what is called a superellipse (not a standard circle) so the curve is smoother.
The Difference from Google
While Google offers an open and customizable Design System, Apple is far more strict. If you want to publish an app on the App Store, you must follow the HIG — otherwise the app gets rejected. This ensures all apps on iPhone maintain a certain quality standard.
Lessons You Can Apply to Your Work
1. Start Small but Start
You do not need to build a complete Design System like Google's from day one. Begin with a color palette, typography scale, and the 10 most important components you use. Then grow it over time.
2. Document Everything
A real Design System is not just Figma files. It is documentation. Every component needs: when to use it, when not to use it, and examples of correct and incorrect usage.
3. Keep Code and Design in Sync
The biggest problem with Design Systems is that the Figma design ends up different from the actual code. The solution? Make the Design System a single source of truth — through design tokens or shared component libraries.
4. Establish Governance
Who can change the Design System? What is the process for adding a new component? How do we decide to change an existing one? Without clear governance, the Design System becomes chaos within months.
Why This Matters for the Arab Market
In the Arab market, most companies still have not built Design Systems. Every project starts from scratch, and every designer does things their own way. The result? Inconsistent products and slower development.
Arab companies that have started investing in Design Systems — like Careem and Swvl — have seen a significant difference in development speed and product quality. Because the new designer does not start from zero — they start from an existing system.
Conclusion
Design Systems are not a luxury for large companies — they are the foundation of consistent design at any scale. Google and Apple have proven that it is possible to maintain a single design identity across hundreds of products and billions of users.
The most important lesson? Consistency is not the enemy of creativity — consistency is what liberates creativity. When the fundamentals are settled, the designer can focus on innovation instead of wasting time reinventing the wheel.
