If you are looking to stand out from the crowd, then think about double size business cards. These business cards are twice the size of a regular business card.
There are positives and negatives to using double sized business cards.
The positives are the amount of room you have to write your marketing message, and the fact that these large business cards stand out and will get you remembered.
The negatives are that most people will not be able to fit your extra large business cards in their pocket, or into their business card holder.
Before you buy double sized business cards, weigh the positives and negatives!
I would advise you to have your printer give you some sample double size business cards and carry them around to see how much you like them, before you spend money on them.
