Serif vs. Sans
by Adrian Hanft, (18 comments)
I had an interesting talk with my boss the other day about the readability of serif vs. sans serif fonts. He confesses that he is "old-school" and prefers serifs. I find sans serifs easier to read. I am trying to hunt down some current statistics on the subject without success. I read people that say it all depends on what you are used to reading, but I can't find anybody who lists their sources. After reading Ogilvy, I am on a kick for finding statistics. Is there a source for credible statistics that counter Ogilvy's from 20 years ago?

I don’t know of any statistics off-hand, but did refresh my memory of the long history of sans-serifs. If you have The Elements of Typographic Style by Robert Bringhurst, you may want to read section 10.3, “Userifed text faces,” page 239.

Thanks, Kyle. “The Elements of Typographic Style’ is one of those books that us designers should reread once a year. I guess there is a new edition of “Elements” that came out in 2002. Is that the edition you have? I wonder if the new edition talks any about the impact of the internet and current trends.

In my continuing search for a high-profile source for current statistics on serif vs. sans, I have read through a bunch of information that I disagree with. The few people who mention their references are getting their information from sources at least 9 years old. Aside from research on readability on the web (which strongly favors sans serif), I can’t find anyone who says sans serifs are easier to read in body copy in print.
My theory is that we are increasingly seeing more and more sans serif fonts used in print, and therefore sans serifs are becoming as readable, if not more readable that serifs. I think the internet has a lot to do with it. I just wish I could find some high profile source to back me up.

Instead of thinking of one as more readable than the other in an absolute sense, might they be at least partly contextual? Serif font makes a graphic layout slightly harder on the eye, but I can’t imagine reading an entire book in sans serif. I don’t know how much of this is conventional, or how much the historical uses of the fonts relate to intuitive sense of context.

Good point, Chris. I suppose there will never be an absolute answer to the serif vs. sans debate no matter what the research would say. In the hands of a sensitive designer the choice of font is a design element, and readability is a given. Like you said, context would dictate the appropriate font selection.

Here is a test where you can see how many words per minute you read. Somebody should do a serif and sans-serif version.

1) What makes you think that serifs are the key factor in readability?
2) What makes you think that readability in various circumstances is inherent to the typeface?
3) What makes you think David Ogilvy was right when he wrote about the subject?

Gunnar, It seems like you misread me. In response to your questions:
1) What makes you think that serifs are the key factor in readability? I never said serifs are the key factor in readability, although the majority of people do think that. I am looking for someone who gives an alternative opinion. For example, I think the idea that “serif’s help the eye connect letters in words making it more readable” is a myth that needs to be debunked, but I can’t find anyone who says that. Do you have any sources that would be helpful?
2) What makes you think that readability in various circumstances is inherent to the typeface? I said, “In the hands of a sensitive designer, readability is a given.” The typeface doesn’t matter if it is set well. Lets face it though, Times is easier to read than really grungy fonts.
3) What makes you think David Ogilvy was right when he wrote about the subject? I think he was right when he wrote about it because at the time, sans serifs weren’t used as much as they are now. I think today, his writing is outdated, but since there isn’t a high profile alternative, Ogilvy continues to be presented as truth. I think that is a mistake.

This doesn’t have anything to do with serifs, but I thought it was an interesting study: http://psychology.wichita.edu/surl/usabilitynews/62/whitespace.htm It has to do with the effect of white space and leading on readability.

The reason san-serif is popular for web publishing is dependent upon how characters are rendered on a computer monitor. San-serif is more “crisp” and consistent than “serif” because of the way the letter forms are translated into pixels. Especially at smaller sizes, making san-serif much more legible for web-publishing. I would argue that it’s not a matter of aesthetic preference but technological limitation that makes san-serif the king in web publishing.
Serifs do provide extra visual cues to character recognition not only with individual letterforms but to groupings of letters. They also reinforce the horizontal reading pattern. Both of these things would seem to add up to improved readability in print publishing. At least when addressing the issue of body copy.

Well, from what seems would be an easy answer - it seems like many factors go into readability…i have used both serif and sans serif for the body of annual reports and sometimes…actually much of the time…appreciate the simplicity and clean lines of a sans serif…super thin and super condensed please…but i have noticed that older clients prefer the type to be at 14 point if i take that route….i can get away with using a smaller size when using serif and it seems to not pose as much of an issue. however, increased leading and tracking out a bit also lends itself to easy reading.
here is a site i found with some interesting remarks…it appears that it also depends on what the person is used to reading…if they grew up reading serif faces, their eye will naturally find that easier to read.

Type and Layout: How Typography and Design Can Get Your Message Across-or Get in the Way. Author: Colin Wheildon Publisher: Berkeley, CA: Strathmoor Press, 1995 Price: $24.95 US A quote, from page 60, may answer your question:
“Body type must be set in serif type if the designer intends it to be read and understood. More than five times as many readers are likely to show good comprehension when a serif body-type is used instead of a sans serif body type.”

After 30 years as a graphic designer having type set for one thing or another, it always seemed to me that serifs were most valuable because they created more equal spacing for each letter. Obviously “m’s” take up more room than “i’s”, but with serifs the playing field is more even.
That said, reading is more instant recognition of total words rather than a collection of individual letters (we all have probably received the e-mail where the gibberish is actually recognizable because our eyes and brains recognize words).
Sans Serif make word recognition slower at best, and more difficult at worst because the “i’s” get lost among the “m’s” without more the reader needing to concentrate more.
So - serifs make reading faster (therefore probably easier) because we can recognize the words quicker using optical spacing on a more level playing field between thick and thin letters.
Because we all use Arial (or equivalent), we are getting used to “recognizing” words without having to recognize the letters. However, it seems to me that any serif face is instantly more readable than a sans serif face the first time; as well as for unfamiliar words, etc.

A very good book on the subject is Colin Wheildon’s “Type and Design”, in which the author conducts tests for readability and comprehension of a variety of typographic styles and elements.

The U.S. Postal Services uses a Sans Serif font throughout their DMM (Domestic Mail Manual). 800 some pages of picky, technical regulations, etc.
This is either a huge endorsement of or a great argument against using sans serif fonts — I can’t decide which.
Maybe the USPS has a study they based their decision on?

There was a link to this post in Denny Hatch’s Business Common Sense enewsletter. Here is a link to Denny’s story about how he changed his newsletter’s font from Serif to Sans Serif based on the research of one of his readers. The suggestion to use a sans serif font seemed crazy to Denny who was relying on information published in 1977 (Why Johnny Can’t Read). I can’t resist quoting this scary bit of logic: “But ultimately, the computer screen is a print medium. Whenever I create an e-promotion for a client, I think of it as direct mail on glass.” Apparently, the sans serif decision wasn’t “common sense,” but it is the right decision nonetheless, and it is nice to see someone change.
I also wanted to give a link to another Be A Design Group post that talks about children’s preference towards sans serif fonts, in case you haven’t read it yet.

I haven’t read any of the sources you all have sited, so I’m talking blind here, but let me tell you what I think (at the risk of repeating someone else)
Here is what I know — and this thread is getting long, so I’ll keep it super clean:
a) Serif fonts have a lot more variation between letter widths. Readability is better for it.
b) Cap height vs x-height. Lowercase is always easier to read. Why? Because of the ascenders and descanters — they break up the word. To test this, read a road sign from as far away as possible, and see if you can make it out. This is exactly why road signs have lowercase text (except the capitalization of the first letter).
c) Ligatures. Sans serif fonts don’t have them. Period. These glyphic letterforms are highly readable and stand out.
d) Density — for lack of a better word. If the font itself is more modern, it is more difficult to read. Modern serif fonts have a lot of contrast between Stems and Strokes. Too much contrast is hard to read. Test it yourself.
e) Finally, ANY font that is closer to the letterforms of the 1800’s are based more closely to freehand text that predated press. So what does that mean? Old printers based their fonts on shoulders, spines, tails, stresses, ears etc that closely resembled what the clergy (for example) were doing by hand! It cannot be disputed that these make a font more readable. The of a Times New Roman ‘g’ that distinctive ear is an instant label!
That’s my bit. I would love to hear replies — maybe I’m dead wrong? Cheers everybody!
