What's the minimum font size for readable business card text?

Never drop below 7pt for anything on a business card. Below that, ink can fill in fine letterforms and older eyes struggle in normal lighting. Building a small type hierarchy keeps every element legible while still letting your name lead.

• Sans-serif fonts hold up better at small sizes than script or heavily decorative faces.
• Keep strong contrast between text and background so small type stays crisp.
• Print a proof and read it at arm's length before you approve the final file.
