Font sizes that are 8 points and under are not cool!
I don’t care how you slice it, this is one Web 2.0 lie that has to die! (yes, I feel like rhyming today) Smaller font does not mean cooler business cards, even if you have a gradient and a badge (or button) that pops off the page of your business card.
As I said in a previous post, you can choose your own font, but make the size above 8 points. If you are using Photoshop, this is the number that is in the text field box. If you are having your business cards designed by someone else, make sure that you can read the font from 4-5 feet away.
To do this, have someone hold your business about an arms length away from you, then take a half step back. This will put you about 3-6 feet away depending on how tall you are and how long of arms you have.
Whatever you do, please keep it your text above 8 points or you might just end up with all of your business cards in someone elses trash can!
