Are you proud of your business card? Do you think it’s the best designed card in the world? How many people have commented on the design of your card when they received it? If you’re like most people, no one has said a word. Although good design means different things to different people, designers can agree on the following 4 business card design mistakes. You should avoid these in designing your business cards and if your printed business cards contain one of these faux pas, seriously think about redesigning and printing new ones.

1. A cluttered business card: Appealing cards don’t use up every inch of the cardstock. People get overwhelmed when they see a lot of info in a small space. Too much print looks unprofessional. Keep the vital info – name, your title and company, address, email, Web site and phone numbers. If you have room, you can include a tagline. Use the back of the card if you’d like. Just be sure to leave some white space, which is a design term for empty space.

2. Small print: If people need a magnifying glass to read your name on your business card, it’s too small! Obviously, people aren’t going to take the time to squint their way into understanding your text. Don’t sacrifice readability just to get a tagline or extra info on your card. A good rule of thumb is to make your name 9 points in size, your company name 12 points, and the rest of the type no smaller than 7 points. Using a hierarchy of sizes will also help your design look clean and uncluttered.

3. Having a plain white card: White cardstock with black printing. How original! So many people use this format for a business card that if you do, yours will be hard to find in the sea of white. Make your card a nice cream cardstock, or gray, or go crazy and go for black or some other color that still fits your brand’s image. I love the colors of this card and the design is still simple with the bright blue.

4. Crazy shape: I actually like creative business cards that aren’t rectangles. They look good. But it can be a big design problem because then where do recipients put your card? If it doesn’t fit in a wallet, your business card has a much higher death rate (e.g., being thrown away). Rounded corners are okay because the card will still fit in a wallet or Rolodex, but beyond that you’re pushing it. This business card is almost pushing it, but I think it would still have a high “keeper” rate because it’s the traditional size with rounded corners.

If you wait to redesign and print new cards when your current stash runs out, will it be worth it to lose a few new clients along the way? Clients that you might have gotten if your business card had been more impressive? I don’t think so. Business cards are one of the cheapest marketing tools you’ll ever use, so think of new cards as an investment in your business.
