Why Typography Matters More Than You Think

Good typography is invisible. Bad typography is everywhere. The choice of typeface communicates before a single word is read — it sets tone, establishes hierarchy, and builds trust with your audience.

"Type is a beautiful group of letters, not a group of beautiful letters."

When pairing fonts, contrast is key. A serif heading with a sans-serif body creates natural visual hierarchy without any additional styling.
