Typography as Interface: Why Inter and Outfit Rule the Web

Typography is 90% of the web. It's not just about what you say, but how it looks when you say it.

When building this portfolio and Rune AI, I didn't just pick fonts that "looked nice." I treated typography as core UI infrastructure. The right font choice handles density, scales across devices, and subconsciously communicates the brand's personality before a user reads a single word.

Here is why Inter and Outfit are the power couple of the modern web, and how I use them.

The Workhorse: Inter

I use Inter for the body execution, dashboards, and dense information layers in Rune AI.

Inter was designed specifically for computer screens. It features a tall x-height, which makes lowercase letters easier to distinguish at small sizes.

In Rune's chat interface, readability is paramount. Users are parsing AI-generated text rapidly. Inter disappears into the background, letting the content take center stage.

The Personality: Outfit

While Inter handles the logic, Outfit brings the soul. I use Outfit for headings, brand moments, and the primary navigation of this portfolio.

Outfit is a geometric sans-serif, similar to classics like Futura, but with modern, humanistic touches. It feels "tech" but not "robotic."

Where I Use Outfit

1. Main Headings (H1-H3): Its geometric shapes create a strong visual hierarchy.
2. Navigation Links: The rounded characters feel friendly and clickable.
3. Lab Cards: It pairs perfectly with the futuristic, experimental vibe of the Galaxy and Antigravity labs.

The Pairing Strategy

Great design relies on contrast. You need a reliable "Straight Man" (Inter) to let the "Star" (Outfit) shine.

css

/* My Typography System */
 
/* The Star */
.font-display {
  font-family: 'Outfit', sans-serif;
  letter-spacing: -0.02em; /* Tighter tracking for headlines */
}
 
/* The Workhorse */
.font-body {
  font-family: 'Inter', sans-serif;
  line-height: 1.6; /* Generous breathing room for reading */
}

Conclusion

Fonts are the clothing of your words. Inter is the tailored suit—professional, functional, and fits anywhere. Outfit is the statement accessory—bold, memorable, and distinct.

Together, they create an interface that is easy to read but impossible to forget.
