ACUMIN by Robert Slimbach is a new type family from Adobe that does for book (and ebook) designers what Helvetica has always done for graphic designers. Namely, it provides a robust yet water-neutral sans-serif, in a full suite of weights and widths. And unlike the classic pressing of Helvetica that comes on everyone’s computers—but like Helvetica Neue—Acumin contains real italics for every weight and width.
Reading about the design challenges Slimbach set himself (and met) helps you appreciate this new type system, whose virtues are initially all too easy to overlook, because Acumin so successfully avoids bringing a personality to the table. Enjoying Acumin is like developing a taste for exceptionally good water.
Nick Sherman designed the website for Adobe, and its subtly brilliant features are as easy to miss at first look as Acumin’s. For starters, the style grid on the intro page dynamically chooses words to fit the column based on the viewport size. Resize your browser and you’ll see how the words change to fill the space.
Heaps of behind-the-scenes calculation allow the page to load all 90 (!) fonts without breaking your pipes or the internet. Developer Bram Stein is the wizard behind the page’s performance.
Nick uses progressively enhanced CSS3 Columns to create his responsive multi-column layout, incorporating subtle tricks like switching to a condensed font when the multi-column layout shrinks below a certain size. (This is something A List Apart used to do as well; we stopped because of performance concerns.) In browsers like IE9 and earlier, which do not support CSS3 Multiple Column specification, the layout defaults to a quite readable single column. Nick adds:
It’s the first time I’ve used responsive CSS columns for a real-world project. This was both frustrating and fun because the CSS properties for controlling widows and orphans are very far behind what’s possible in InDesign, etc. It also required more thinking about vertical media queries to prevent a situation where the user would have to scroll up and down to get from the bottom of one column to the top of the next. If the viewport is too short to allow for easy reading across columns, it stays as a single column.
He describes the challenges of creating the site’s preview tool thusly:
We had to do some behind the scenes trickery in order to get the sliders to work for changing widths and weights. It’s a good way to allow people to type their own text and get a feeling for how the family can be used as a system for body text and headlines (unlike Helvetica, which is more limited to the middle range of sizes). Chris Lewis helped out a lot with getting this to work. It even works on a phone!
Book designers have long had access to great serif fonts dripping with character that were ideal for setting long passages of text. Now they have a well-made sans serif that’s as sturdy yet self-effacing as a waiter at a great restaurant. Congratulations to Robert Slimbach, Adobe, and the designers and developers mentioned or interviewed here. I look forward to seeing if Acumin makes it into new website designs (perhaps sharing some of Proxima Nova‘s lunch), especially among mature designers focused on creating readable experiences. And I pray Acumin makes its way into the next generation of ebook readers.
(Just me? In both iBooks and Kindle, I’m continually changing typefaces after reading any book for any period of time. All the current faces just call too much attention to themselves, making me aware that I am scanning text—which is rather like making filmgoers aware that they are watching projected images just when they should be losing themselves in the story.)
