Design Principles Every Developer Should Know

Great software isn't just functional — it's a pleasure to use. Understanding a few foundational design principles can make a huge difference in the products you build.

1. Hierarchy

Guide the user's eye with size, weight, and placement. The most important information should be the most visually prominent.

2. Whitespace

Empty space is not wasted space. Generous padding and margins make interfaces feel calm, readable, and professional.

3. Consistency

Repeat patterns deliberately. Consistent button styles, spacing, and typography create a sense of reliability and trust.

4. Contrast

Ensure sufficient contrast between text and backgrounds for readability and accessibility. A minimum contrast ratio of 4.5:1 is the standard.

5. Feedback

Every interaction should have a response. Loading states, hover effects, and success/error messages keep users informed and in control.

Start applying even one or two of these principles to your next project and see the difference it makes.
