What size should social media icons be on a business card?

Social icons need to be recognizable without crowding your layout. Aim for a height between 4 mm and 6 mm, which reads clearly at arm's length while leaving room for the rest of your details.

• Target height: 4 mm to 6 mm.
• Keep every icon the same size for a tidy row.
• Use even spacing between icons so none look crammed.
• Test at actual print size before finalizing, not zoomed in on screen.
