Inter vs Roboto: Which to Use
The Inter vs Roboto question is the default-UI-font debate for modern product teams. Both are free, screen-optimized, and extremely common in apps and dashboards, but they come from different design philosophies: Inter is a contemporary UI face tuned for sharp legibility, while Roboto is Google’s Android system font with a neo-grotesque backbone. Here is how they differ and which to use.
Both feature heavily in our best Google Fonts and best sans-serif fonts roundups, and we cover each in depth at Inter and Roboto.
What’s the difference between Inter and Roboto?
Inter was designed by Rasmus Andersson and first released in 2016, built specifically for user interfaces and computer screens, with a tall x-height, generous spacing tuned for small sizes, and a rich set of OpenType features (tabular figures, contextual alternates, slashed zero). Roboto was designed by Christian Robertson and released by Google in 2011 as Android’s system font; it is a neo-grotesque with subtle mechanical skeleton and slightly humanist touches, and it underpins Material Design.
The short version: Inter is the newer, UI-first face that excels in data-dense, modern web products; Roboto is the established Android default with a more neutral, system-native feel.
How do they look different?
Inter has a notably tall x-height, which makes text look bigger and clearer at small UI sizes, and its letterforms are slightly wider and more open. Roboto is a touch more condensed in feel, with a mix of geometric curves and grotesque straightness — its proportions read as efficient and a little tighter. Inter’s terminals and apertures are tuned for crispness on screen; Roboto can feel marginally more compact and “system default” by comparison.
In practice, Inter often looks more modern and intentional for a custom product brand, while Roboto looks native and unobtrusive, especially on Android. Both offer variable-font versions and extensive weight ranges, so they scale from captions to headings cleanly.
Which is better for UI and dashboards?
For data-dense UI, dashboards, and modern web apps, Inter is usually the stronger pick. Its tall x-height, tabular figures, and contextual alternates were designed for exactly this — numbers line up, small labels stay legible, and the overall look feels current. Roboto is still an excellent UI font and the right default if you are building for Android or want tight Material Design consistency. If you need numbers to align in tables, Inter’s tabular figures give it a practical edge for analytics interfaces.
Which is better for body text and branding?
For body text, both are comfortable, but Inter‘s larger x-height and open spacing tend to read a little easier at small sizes on screen, while Roboto is highly familiar and neutral. For branding, Inter reads as modern, technical, and product-led — a popular choice for SaaS and developer tools — whereas Roboto reads as neutral and system-native, which can feel less distinctive as a brand voice. If you want a warmer alternative for body copy, compare Lato vs Open Sans, and for Roboto’s neutrality versus a humanist option see Roboto vs Open Sans.
Are Inter and Roboto free?
Yes. Both Inter and Roboto are free and open-source under the SIL Open Font License (OFL), and both are available on Google Fonts. You can use them in commercial websites, apps, and print at no cost, self-host the static or variable files, and bundle them into software. Neither has a paid tier, which is part of why they are two of the most common UI fonts on the web.

How do their families and variable fonts compare?
Both ship modern, well-built families, but with different strengths. Inter is offered as a high-quality variable font with a full weight axis and a slant axis, plus a long list of OpenType features — tabular and old-style figures, a slashed zero, contextual alternates, and even a “Display” optical adjustment for larger sizes. That makes it unusually configurable for a free font, which is why design systems lean on it. Roboto also has a variable version and a deep static family, and crucially it comes with companion fonts: Roboto Condensed, Roboto Slab, and Roboto Mono, letting you build a coordinated system across UI, display, and code.
If your product needs a matching monospace or slab in the same voice, Roboto’s family ecosystem is a real advantage. If you want fine typographic control and figure styles for data-heavy screens, Inter’s feature set wins. Both load efficiently from Google Fonts and self-host cleanly, and both have excellent language coverage. For most teams the choice still comes down to platform and tone rather than raw capability. Our best Google Fonts guide places both alongside other strong UI options.
Which should you choose?
Choose Inter for modern web products, dashboards, and SaaS where a tall x-height, tabular figures, and a contemporary feel matter. Choose Roboto when you are building for Android, want Material Design consistency, or prefer a neutral system-native look. Because both are free and screen-optimized, the deciding factors are platform (Android favors Roboto) and brand tone (Inter reads more current). For analytics-heavy interfaces, Inter’s number handling makes it the default recommendation.
Frequently Asked Questions
Is Inter better than Roboto for websites?
For most modern websites and web apps, Inter is the more popular current choice thanks to its tall x-height, crisp small-size legibility, and tabular figures. Roboto remains an excellent, neutral option and is preferable if you want Android-native consistency. Both are free and easy to load from Google Fonts.
Why is Inter so popular?
Inter was designed specifically for screens and UI, with features developers and product designers want: a large x-height, careful small-size spacing, tabular numbers, a slashed zero, and a variable font. That practical focus, plus a free open license, made it a default for modern SaaS and dashboard interfaces.
Does Roboto look like Helvetica?
Roboto shares some neo-grotesque traits with Helvetica but mixes in geometric curves and subtle humanist touches, so it is not a Helvetica clone. It reads as more mechanical and screen-tuned. Inter is also in the neo-grotesque lineage but is wider and taller in x-height than either.
Should I use Inter or Roboto for an iOS app?
For iOS, Apple’s own San Francisco is the native default, but if you want a cross-platform custom font, Inter is the more common choice because it reads as modern and platform-neutral. Roboto can feel distinctly Android on iOS. Inter’s tall x-height also keeps small labels crisp on high-density displays.
Are they free for commercial use?
Yes. Both Inter and Roboto are licensed under the SIL Open Font License, so you can use them commercially in websites, apps, and print at no cost, including self-hosting and bundling in software. Just keep the license file when redistributing the font files.
