Difference Between UI and UX Design

UI vs UX — The Key Difference

A classic analogy: UX is the foundation and layout of a house; UI is the paint, furniture, and decor. Both are essential for a great product.

Detailed Comparison

Aspect	UX Design	UI Design
Definition	User experience	User interface
Question	Is it usable?	Is it beautiful?
Deliverables	Wireframes, flows	Mockups, visuals
Tools	Figma, Miro	Figma, Photoshop
Concerns	Logic, structure	Color, typography

An Example: A Login Form

• UX — decides the fields, validation, error handling, flow.
• UI — designs the colors, button style, spacing, fonts.

Why You Need Both

Beautiful but confusing = bad UX. Usable but ugly = bad UI. Great products nail both.
