How do you design for multiple screen sizes and devices?

Designing for multiple screen sizes begins with defining breakpoints based on actual device usage data from Google Analytics 4 rather than arbitrary pixel values. Typically, designs are produced for at least three breakpoints: mobile (360 to 480px), tablet (768 to 1024px), and desktop (1280px and above).

In Figma, responsive constraints and auto layout components allow designers to test how elements reflow before handing off to developers. A component-based design system ensures that each UI element, from cards to navigation bars, has defined responsive behavior documented alongside the visual design. Developers implement responsive logic using CSS Flexbox, Grid, and media queries, with Tailwind CSS providing a utility-based approach that maps directly to design breakpoint specifications.
