What are the most important business card design tips?

Good business card design is mostly restraint. Give the eye one clear path, keep the essentials front and center, and let white space do the work. A card that tries to say everything ends up saying nothing memorable.

• Stick to one typeface family and vary weight or size for hierarchy instead of mixing fonts.
• Keep the logo visible but not oversized, and leave generous margins on every side.
• Limit contact details to the essentials: name, title, phone, email, and website.
• Choose a stock of at least 14pt so the card feels professional in the hand.
• Treat white space as a feature, not wasted room. It is what makes the card readable.
