WCAG 2.1 Guidelines in UX Design: A Practical Framework for Accessible User Experiences
WCAG 2.1 are four principles that define whether an experience is truly accessible. These principles—often referred to as POUR—act as a mental model for UX designers. If a user interface fails even one of these principles, a portion of users will struggle or be completely blocked from using the product. From a UX perspective, POUR […]
Contrast Ratio in UI
Contrast ratio plays a quiet but critical role in how users experience an interface. It determines how easily people can read text, identify buttons, and understand visual hierarchy without effort. When contrast is done right, users don’t notice it at all—they simply move through the interface smoothly. When it’s done wrong, even the most beautiful […]
Vertical Rhythm in UI: The Hidden System That Makes Interfaces Feel Clean and Readable
Vertical rhythm in UI is how space flows vertically across a screen. It’s the invisible system that controls how text, headings, buttons, images, and sections stack on top of each other.

Mental Model in UI/UX: Designing Interfaces That Match How Users Think
A mental model in UI/UX is how users think a product works before they ever use it. It’s the expectations they bring from past experiences—other apps, real-world objects, and familiar patterns. And whether your interface feels intuitive or confusing comes down to one thing: how closely your design matches that mental model. When a product […]

Visual Hierarchy in UI Design: How to Guide the User’s Eye
You wouldn’t know who to listen to, feel overwhelmed, probably turn around and leave. This is exactly what happens when a website lacks Visual Hierarchy.

Why Cognitive Load Matters for UX Designers
10 Examples of Bad vs. Good Microinteractions (The 2025 Guide)
The difference between a “good” app and a “great” app isn’t usually the features. It’s the details. It’s the satisfying “pop” sound when you send a message. It’s the way a button morphs into a loading spinner so you know something is happening. These are Microinteractions. And in 2025, they are not just “eye candy.” […]
The 60-30-10 Color Rule: How to Create the Perfect UI Color Palette
You stare at the color picker for hours. You try a hundred different shades of blue. But somehow? It still looks “off.” It looks messy. It looks amateur. Don’t worry, you are not alone. Even senior designers struggle with this. There is a “secret weapon” that interior designers have been using for decades to fix […]
Typography Scales: How to Calculate Vertical Rhythm
You might think that great typography is just about picking a nice font. (I used to think that too). But here is the truth: Good typography isn’t about the font. It’s about the math.
