“Web Design is 95% Typography”
Blogs should take heed of Oliver Reichenstein’s words. Good typography in your design is good readability, usability, and balance. Sadly, though, typography is a much ignored aspect of design online and designs fall victim to measure being too long, narrow linespaceing, low contrast, and poor grid structure. But the problem I see most in blogs, especially blogs trying to monetize every last pixel of their screen is poorly placed ad’s disrupting the flow of content and lack of white space.
While typography online will never have the same resources as print, the foundations are the same and should be an important consideration in the look of your design. Where they differ is how people read web content scanning much faster and not in the traditional up and down columns associated with newsprint. Web typography is also limited by the pool of fonts available and being rendered differently on various platforms.
Typography should be an integral part of your design, and it’s worth learning more about typography in general to better understand the art of type. From choosing the right font, to leading and tracking on the text.
