Inter vs Roboto: Which Sans Is Better for UI? (2026)

Q: Which font is better for mobile UI: Inter or Roboto?

Inter is often preferred for mobile UI because of its taller x-height and tighter spacing, which improve readability on small screens. Roboto is also excellent and has been widely used in Android apps, so either works well depending on your design language.

Q: Are Inter and Roboto free to use commercially?

Yes, both Inter and Roboto are licensed under the SIL Open Font License (OFL), which allows free commercial use, modification, and distribution without royalties.

Choosing the right typeface for your web or mobile interface can feel overwhelming, especially when you're torn between two industry-standard sans-serif fonts like Inter and Roboto. Many designers and developers struggle with readability on high-resolution screens, inconsistent weight availability, and language support gaps that break layouts in global applications. Inter and Roboto both claim to solve these problems, but they approach them differently. Inter, designed by Rasmus Andersson, is built specifically for screen interfaces with a focus on pixel-perfect rendering, while Roboto, created by Christian Robertson, offers a more geometric and friendly aesthetic that has powered Android and Google products for years. Understanding their nuances is critical for projects that demand both performance and visual harmony.

When evaluating fonts for UI work, three to four key criteria should guide your decision: readability at small sizes, weight range for hierarchy, language support for international audiences, and file size for fast loading. Both Inter and Roboto are available under the OFL license, making them free for commercial use. Inter provides six weights, which is adequate for most interfaces, while Roboto also offers six weights, giving both fonts similar flexibility for headings, body text, and captions. However, Inter is known for its tighter spacing and taller x-height, which can improve legibility on dense mobile screens, whereas Roboto's slightly wider letterforms may feel more approachable in long-form reading. Both fonts support Latin, Greek, Cyrillic, and English scripts, making them suitable for multilingual projects.

Looking at the data provided, Inter has been downloaded 172 times on FontHubs, while Roboto has 77 downloads, suggesting that Inter is gaining traction among the FontHubs community. Both fonts are classified as sans-serif (无衬线体) and share identical language support for Latin, Greek, Cyrillic, and English. This parity means that your choice will likely come down to subtle visual preferences rather than technical limitations. For example, if your project targets modern web apps with a clean, utilitarian look, Inter's precise geometry may appeal to you. On the other hand, if you're building a mobile-first interface that needs to feel warm and familiar, Roboto's rounded terminals and humanist touches could be a better fit.

To download and use either font on FontHubs, simply navigate to the font's page, click the download button, and save the WOFF2 files. Both fonts are available in six weights, though specific file sizes are not provided in the data. For web use, you can host the fonts locally or use a CDN. For mobile UI, embedding the fonts in your app's asset folder ensures offline availability. When comparing Inter vs Roboto for web and mobile UI, consider that Inter's design was optimized for variable font technology and high-DPI displays, making it a strong candidate for responsive layouts. Roboto, with its long history on Android, offers proven performance across millions of devices. Ultimately, the best choice depends on your brand's voice and the reading environment. If you prioritize modern, crisp rendering and a no-nonsense aesthetic, Inter is your font. If you want a versatile, time-tested typeface that feels approachable and works well in both light and dark modes, Roboto remains a reliable option.
