When it comes to modern web design, UI/UX, and clean digital branding, few typefaces have gained popularity as quickly—or as widely—as Inter. If you browse tech products, SaaS dashboards, blogs, or AI tools, chances are you’ve already seen it hundreds of times.
Inter is everywhere, and for good reason.
This blog breaks down what makes Inter special, how it performs in real-world design, its strengths and weaknesses, and whether it should be your next go-to font.
What Is Inter Font?
Inter is a modern sans-serif typeface designed specifically for screens. Created by Rasmus Andersson, a designer with a strong background in digital product development, Inter was built to solve a simple problem:
➡️ Most fonts look good at large sizes—but not at small UI sizes.
Inter was engineered to be pixel-perfect on high-density displays, making it one of the cleanest and easiest fonts to read in digital environments.
It is now widely available on:
- GitHub
- Most major design tools (Figma, Adobe XD, Sketch, etc.)
- Google Fonts
And the best part? Inter is open-source and free to use.

- Larger x-height

This makes it ideal for UI text, buttons, menus, forms, and descriptions.
2. Highly Versatile for Any Project
