How small can social media handle text be on a business card?

Do not drop below 7.5pt for social handle text. At that size most people can still read it comfortably, but anything smaller starts to strain the eye once the card is printed. For reliable readability, aim a touch larger and lean on a clean typeface.

• Treat 7.5pt as the hard floor, not the target.
• Aim for 8 to 9pt in a clean sans-serif font for easy reading.
• Proof the design at actual print size. Type that looks fine on a big screen can be tiny in hand.
• Give the handles a little breathing room so small text does not crowd against other elements.
