Starting a career in UI/UX design can feel overwhelming. With so many tools, principles, and trends to learn, where do you begin? This guide covers the fundamentals that every aspiring designer should master.
Understanding UI vs UX
User Interface (UI)
The visual elements users interact with:
Colors and typographyButtons and iconsLayouts and spacingAnimations and transitionsUser Experience (UX)
The overall feel and flow of the product:
User research and personasInformation architectureUser flows and journeysUsability testingBoth disciplines overlap and inform each other.
Fundamental Design Principles
1. Visual Hierarchy
Guide users' attention through:
Size (larger = more important)Color and contrastSpacing and positionTypography weight2. Consistency
Maintain uniformity in:
Button styles and behaviorsColor usageTypography scalesSpacing systems3. White Space
Don't fear empty space:
Improves readabilityCreates visual breathing roomHighlights important elementsAdds sophistication4. Accessibility
Design for everyone:
Sufficient color contrast (4.5:1 minimum)Clear focus indicatorsDescriptive labelsKeyboard navigationColor Theory Basics
Building a Palette
Start with:
Primary color (brand color)Secondary color (accent)Neutral graysSemantic colors (success, error, warning)The 60-30-10 Rule
60% dominant color (usually neutral)30% secondary color10% accent colorContrast Matters
Test your combinations:
Good: Dark text on light background
Good: Light text on dark background
Bad: Low contrast combinations
Typography Fundamentals
Font Pairing
Keep it simple:
Maximum 2-3 fonts per projectPair a display font with a readable body fontConsider font superfamiliesType Scale
Use a consistent scale:
12px, 14px, 16px, 18px, 20px, 24px, 30px, 36px, 48px
Line Height and Length
Line height: 1.5 for body textLine length: 50-75 characters optimalLayout Basics
Grid Systems
Use grids for consistency:
12-column grids are versatileDefine gutters and marginsAlign elements to grid linesResponsive Design
Design for all screens:
Mobile-first approachBreakpoints for different devicesFlexible images and containersEssential Tools

Skipping research: Design without understanding usersToo many fonts: Creates visual chaosIgnoring hierarchy: Everything looks equally importantInconsistent spacing: Random padding and marginsOverlooking accessibility: Excluding users with disabilitiesBuilding Your Portfolio
