«Proof that type design is all about tricking people’s brains. The letters you see on your screen are not as they seem»

You may think you see the letters you read in books, emails, signs, and, well, the world, as plain as day, but you don’t. In reality, the individual letterforms that make up words have to be drawn in counterintuitive and idiosyncratic ways to adjust for how the brain perceives visual equilibrium. Type designers must employ a series of visual tricks that make you think that the letter B is balanced on top and bottom, and that C and T are the same height—even when they aren’t. All this is to say, the letters you read all day are not as they seem. In fact, type design itself is a craft of illusions.

But unlike most magicians, Jonathan Hoefler (@HoeflerCo) is revealing his secrets. The typographer and founder of Hoefler&Co. recently explained on his blog that he and director Brian Oakes wanted his episode in the Netflix documentary series Abstract: The Art of Design (@sdadich) to be more than a profile; it should “offer viewers some practical insights into the mechanics of the craft itself.” He’s now made those lessons available free to download on his website, no Netflix subscription required.

So why is our mind playing tricks on us? It could be physiological. One theory mentioned by Hoefler, based on a study published in the Proceedings of the National Academy of Science, is that “because our brains evolved to reckon with the three-dimensional world, the expectations that bring to bear upon two-dimensional forms often don’t apply. When there’s a disconnect between what we see and what we expect to see, we experience this as an optical illusion.”

And while these illusions are most closely associated with typography, they can have ramifications for graphic design, too, affecting how we perceive everything from a single arrow to logos and entire visual systems, according to Hoefler. The best way to solve these design problems is to get to know them. With Hoefler’s newly available Tools for Teaching Typographic Illusions, that just got a little bit easier.
