Principles of UI Whitespace and Density
Whitespace is not empty space — it's a design element that creates visual rhythm. Generous whitespace makes content easier to read, clarifies hierarchy, and builds a premium, trustworthy brand impression. However, data-dense UIs like dashboards need compact spacing to fit more information on screen.
The key is choosing the right density for the content's purpose and context. Reading-focused layouts need loose spacing; data-intensive screens need compact spacing; general product UIs land in the standard middle ground.
Using the 8px Grid System
Setting all spacing values to multiples of 8 (4, 8, 16, 24, 32, 48, 64px) creates visual consistency and simplifies developer handoff. Figma, Material Design, and Tailwind CSS are all built on this system.
