A good business card should convey the overall image of your business — not easy, considering the card measures only 2 inches by 3.5 inches. How can you possibly get a message across in such a small amount of space?

Some of our favorite tips:

• Use your logo as the basis. Make it the largest element on the card.
• Keep it simple. Do not cram too much information on the card.
• Do include the essentials — your name, title, company name, address, phone and fax numbers, and email and website addresses.
• Make sure the typeface is easily readable
• Stick to one or two colors.

Once you’ve got business cards, make the most of them:

• Always give people more than one card (so they can give it to others).
• Include your card in all correspondence.
• Carry cards with you at all times, in a card case so they’re clean and neat.
