In your design, sometimes it will be much easier to use all uppercase fonts. Naturally, when you type in caps, each letter takes the same amount of space horizontally and vertically. So, you can closely arrange a word without overlapping the words below or above it which often happens when dealing with the g's, y's, l's or k's in lowercase letters. Of course there's no denying that a combination of uppercase and lowercase letters can sometimes make your design more interesting. It's really up to your creative mind to decide. But I'm writing today to share some of the free fonts available out there that will look fabulous in capital letters.
