Nothing is more important to making a good first branding impression than your business card. In addition to the information included, a card's look and feel also sends a strong message about your business.

Choosing low-quality paper stock.  Inexpensive paper stock may save you money, but it often leaves you with a card that feels cheap. Touch is an important sense and plays a role in memory recall.

Using a design template that does not match the logo.  Assuming you want a business card to be taken seriously and help brand your company, you need a design that works with your logo.

Adding too much color to the card.  When you want to get someone's attention, do you scream? Probably not, if you want to avoid scaring them. So why scare potential customers with a super-bright, rainbow-colored card?

Making the card too unique.  You want your card to stand out, certainly, but not so much that its difference makes people uncomfortable. Complex dye-cuts, extremely oversized cards, and odd card stocks (like metal) should be avoided.

Making the logo gigantic.  In general, the bigger the company, the smaller its logo appears on business cards. If you want to look like a Fortune 500, size your logo appropriately.
