The biggest tech companies all start from a short set of written design principles. Here's how Android, Airbnb, iOS, Uber and Facebook frame theirs.
UX design principles are the conceptual and methodological foundation of a design system, not visual rules but the philosophy that guides the whole process. This roundup collects the published principles of five major companies: Android (Enchant Me, Simplify My Life, Make Me Amazing), Airbnb (Unified, Universal, Iconic, Conversational), iOS (themes of Clarity, Deference, Depth plus six principles), Uber (Instructive, Non-intrusive, Focused and Timely), and Facebook (Universal, Human, Clean, Consistent, Useful, Fast, Transparent). They overlap in places and contradict in others, which is exactly why studying them helps you write your own.
Key takeaways
- Design principles are a philosophy and method, not just UI/visual guidelines.
- Common threads: universality/accessibility, clarity, consistency, user control and speed.
- Android frames principles emotionally (enchant, simplify, empower).
- Uber's are almost entirely about the experience/flow, with UI as a by-product.
- A documented set of principles is the cornerstone of any design system.
Five companies, five philosophies
| Company | Core principles | Emphasis |
|---|---|---|
| Android | Enchant Me (delight, direct manipulation, personalization, learn my preferences), Simplify My Life (be brief, pictures over words, decide but let me undo, progressive disclosure, orientation, never lose my work, consistency, don’t interrupt), Make Me Amazing (transferable patterns, forgiving errors, encouragement, do the heavy lifting, make key actions fast). | Emotional / usability |
| Airbnb | Unified (each piece serves the whole system), Universal (welcoming and accessible to a global community), Iconic (bold focus on design and function), Conversational (motion communicates and gives life). | Design system |
| iOS (HIG) | Themes: Clarity, Deference, Depth. Principles: Aesthetic Integrity, Consistency, Direct Manipulation, Feedback, Metaphors, User Control (people, not apps, are in control). | Interface craft |
| Uber | Instructive (educate through clarity, don’t assume knowledge), Non-intrusive (get out of the way, never block critical info), Focused and Timely (right info at the right moment, not all at once). ~77 sub-principles. | Experience / flow |
| Universal (serve everyone), Human (spotlight people, not the UI), Clean (understated canvas), Consistent (reduce, reuse, don’t redesign), Useful (utility over entertainment), Fast (value users’ time), Transparent (honest about what happens and why). | Philosophy / values |
UX design principles are a conceptual and methodological approach, not just building guidelines.
On what design principles really are
It’s striking how these overlap (universality, clarity, consistency, user control) yet differ in framing: Android speaks emotionally, iOS focuses on interface craft, Uber almost ignores visuals in favor of flow, and Facebook reads as a values statement. Reading the originals (linked in the sources) is highly recommended: they show how tech giants think about users, which helps you draft principles for your own product. Whether the work is physical or digital, it starts with clear, documented guidelines.
The conceptual and methodological philosophy that guides a design system and process, distinct from visual rules, UI patterns or specific interface guidelines.
Three: Enchant Me, Simplify My Life, and Make Me Amazing, each broken into specific guidance about delight, simplicity and empowering users.
The Human Interface Guidelines set three themes (Clarity, Deference, Depth) and six principles: Aesthetic Integrity, Consistency, Direct Manipulation, Feedback, Metaphors and User Control.
Recurring themes of universality/accessibility, clarity, consistency, user control and speed, even though each frames them very differently.
Because a documented set of principles is the cornerstone of a coherent design system and guides every later decision. Studying big companies’ principles helps you draft your own.
