The Fuss about Ligatures

Wednesday, November 12th, 2008

I recently started working with an editor on a project. Scanning my document, I noticed she caught many of the typical errors: an extra space here, change curly quotes to hash marks for inches, change this word for that word. . . but what was this? She was circling all my ligatures!

“Turn ligatures off,” the comment said.

What? It must be a mistake! But then, further on in the document, I saw it again!

“What’s going on here?,” I wondered. I had been taught as a graphic designer that the use of ligatures was a mark of good typography. I decided to get to the bottom the issue.

First, let’s look at what ligatures are, and why they exist. Ligatures are combinations of letters, created as part of a typeface’s character set, to avoid collision of elements of letterforms and create more elegant transitions from one letter to the next. Some common ligatures are ff, fi, and fl:

Common Ligatures

Ligatures were popular for setting type in the 15th century, when metal blocks of letters were placed into tracks to compose a printable document. At this time, ligatures were a great time saver, allowing the typesetter to place a single “fi” block into the track instead of separate “f” and “i” blocks—a seemingly small act that made a difference in a book of say 50,000 words.

Later, with the invention of Sans Serif type (with letterforms that have less overlap), modern-era printing (which uses print plates vs. individual blocks of text), the typewriter (with forced equal spaces—monospacing—between letterforms and no ligature keys), and desktop publishing (a decendent of the typewriter, where ligatures are hidden as glyphs that require unusual keystrokes) use of ligatures began to decline. An article about ligatures on ilovetypography.com states that:

Richard Wendorf, in a 2005 lecture The Secret Life of Type, even suggests that the death of the ligature was brought about by a desire to reduce the number of type pieces, and was also influenced by the popular publisher John Bell (1745-1831), who abandoned ligatures.

So ligatures declined. But when did they become despised by editors?

A partial answer to this came when I was reading a follow-up comment to a blog entry about ligatures. The person had written:

A question that I have is what does the ligature actually do for usability. Is it to help the flow of reading, or is it just to make the text look better?

Another reader responded:

I know of no studies that have broached the topic of ligatures and readability. The ligature was used by ancient scribes to speed their writing; I don’t think the ligature is the product of a desire for improved readability; however, as Stephen Tiano writes below, perhaps they do perhaps inadvertently perform this function.

When I asked my editor about her ligature bias, she suggested that the ligature was a stylistic dinosaur that confused the reader, decreasing readability due to people’s relative unfamiliarity with these typesetting specialties.

When it comes right down to it, a well-designed paragraph of type should not call attention to individual letters or letterforms. Rather, it should be read effortlessly. In this vein, I considered that it is the task of the designer to determine if a font’s ligature detracts or adds to readability. Some fonts, like Adobe Garamond Pro, were created with readability in mind and have thoughtfully-designed ligatures that enhance the flow of text. Others, such as some sans serif fonts (to be honest, I couldn’t find a bad example—but I’m sure they’re out there), may be better suited to have ligatures turned off. Whichever route you select, take care that you use (or don’t use) ligatures consistently within a single document to avoid confusion.

As for the highly stylized, fanciful ligatures that exist in many faces: I would suggest that they are entirely appropriate in headlines or logotype, where we want readers to notice the beauty and style of the letterforms. Bookman, Mrs. Eaves, and Zapfino are examples of fonts that have exceptionally beautiful ligatures that the world deserves to see!
