Top UI/UX Principles We Follow for Web & Mobile Projects

When users land on your app or website, they make a decision in less than 5 seconds:

👉 “Is this easy?”
👉 “Do I trust this brand?”
👉 “Can I find what I need fast?”

If your design fails that test—you lose a lead, sale, or sign-up.

At Bigsea Infotech, we design every web and mobile experience with UI/UX at the core, making sure that every tap, scroll, and click is intuitive and enjoyable.
 

What’s the Difference Between UI and UX?

  • Term
  • Meaning
  • UI (User Interface)
  • The visual layer – buttons, colors, typography, layout
  • UX (User Experience)
  • The feeling users get while using your product – clarity, ease, speed
  • Both are equally critical to your digital success.

 

Our 10 Core UI/UX Principles for Web & Mobile Design

 

  • User-Centered Design (UCD) Comes First

We design for people, not platforms.

That means we start every project by understanding:

  • Who the users are
  • What they want
  • What frustrates them

Deliverables:

  • User personas
  • Empathy maps
  • Task flows

Clarity Over Cleverness
Confused users don’t convert.

We follow the principle:

  • “Don’t make users think.”


That means:

  • Clear CTAs like “Shop Now” not “Let’s Roll”
  • Straightforward navigation
  • Logical page hierarchy
  • No fluff—just value

Consistency Builds Trust

  • A consistent interface feels familiar, even if it’s the user’s first visit.

Our consistency rules:

  • Button styles stay the same across pages
  • Typography follows a defined hierarchy
  • Icons, spacing, and colors follow a design system
  • This helps reduce cognitive load—and builds trust subconsciously.

Mobile-First, Always
Since 70%+ users are on mobile, we always start our designs from the smallest screen and scale up.

Benefits:

  • Better performance
  • Cleaner layout
  • Easier user journeys
  • Google prefers mobile-first sites for SEO

Visual Hierarchy Guides the Eye
We design layouts that guide users from most important → least important information.

We use:

  • Size (bigger = more important)
  • Color contrast
  • Placement above the fold
  • Bold headlines + soft body text
  • One strong CTA per screen

Feedback Loops for Every Action
Users feel more in control when they get feedback after every action.

We build:

  • Loading animations
  • Button states (hover, active, disabled)
  • Success/error messages
  • Toast alerts

Example: After clicking “Buy Now,” users see a quick confirmation – no wondering “Did that work?”
Accessibility is Non-Negotiable
We follow WCAG accessibility standards to make sure everyone can use your product—regardless of ability.

We design with:

  • High contrast ratios
  • Alt text for images
  • Keyboard navigability
  • Readable fonts + clear labels

Bonus? Google rewards accessible websites with better SEO.


Microinteractions Make UX Delightful
Microinteractions = small animations that make big impressions.

Examples:

  • Heart bouncing when you like a product ❤️
  • Button ripple effect when tapped
  • Smooth hover effects on product tiles
  • These tiny touches increase user satisfaction and session time.



Minimalism Drives Action
Too many choices = no choice.

We remove distractions and use:

  • Focused CTAs
  • Clean layouts
  • Only essential content
  • Visual whitespace

This creates a clear path to conversion—whether that’s a form submission, checkout, or sign-up.
Test, Iterate, Improve
No design is final. We constantly:

  • Analyze user behavior (via Hotjar, Clarity)
  • A/B test button placements and text
  • Track drop-off points in funnels
  • Collect real feedback through usability tests

Good UI/UX is not a one-time job—it’s an ongoing process.
