Double-sided business cards are better if you want to make your cards stand out to maximize your brand image. Rather than trying to cram lots of information onto a small space, a double-sided business card gives you the opportunity to spread things out. You can add a larger logo and tagline without having to worry about cluttering the card. Some people like to use the backside of a business card to take notes about the person they’ve met, but that’s only possible if one side is left blank.
