Frequently Asked Questions
What makes a font good for UI design?
Good UI fonts have high x-heights for small-size legibility, consistent stroke widths for clean rendering, and tabular figures for aligned data. They should work well in buttons, labels, and navigation without becoming fatiguing. Sans-serifs dominate UI because they render crisply at all sizes.
Should I use system fonts or custom fonts in my UI?
System fonts (SF Pro, Roboto, Segoe UI) offer zero download cost and native performance. Custom fonts add brand personality but increase load time. Many teams use system fonts for UI components and custom fonts for marketing sections. Consider Inter as a middle ground—optimized for screens yet distinctive.
What free fonts work well for UI design?
Inter is the gold standard for UI—designed specifically for screens with excellent legibility at small sizes. Nunito Sans offers a friendlier alternative. For more distinctive UI, try Work Sans or DM Sans. All provide variable font options for optimal performance.
