Iota rapidly established itself as the default font on my e-reader. It is a very unique yet highly readable font and sported the single-storey lower case a which i am drawn to for the added openness it renders to the page—further emphasized by the “open” glyph choices of the Iota font.

articulate and typograffic fell into a bit of disuse simply because they were historical points in the progression to Iota—their differences from the font somewhat nuanced.

In this endless exploration of fonts i decided to revisit them—all of them as it would turn out with the return to the serifless lower case j. At 300PPI the serifless glyph is still quite legible and harkens back to its earlier usage, so i revisited the fonts to see what could be done to render them more distinct from each other while retaining the overall dyslexic character of the trio.

dyslexic tunings

the asymmetric glyphs common to all three typefaces remains..

lower case	from hyperlegible shape	to dyslexic shape
b	toothed	toothless-rounded
d	toothed-serifless
p	eared	earless-corner
q	hook-tailed (mapped glyph*)
n	straight
u	toothed	toothless-rounded

To achieve the “character” differences i was seeking, i decided to revisit the font heritage which influenced the glyph choices to begin with..

atkinson hyperlegible

remains the most influential font, providing the base glyph set that was tweaked for dyslexia. Along the way several of the upper case glyphs were changed, notably the crossed capital Q—my being decidedly biased against dense glyphs.

At 300PPI, however, this is not a legibility issue, so the articulate font returns to..

with..

upper case	from prior shape	to hyperlegible shape
G	toothed-serifless-hookless	toothed-serifless-hooked
J	descending-flat-hook-serifless	serifless
Q	straight	crossing

lower case	from prior shape	to hyperlegible shape
j	flat-hook-serifed	flat-hook-serifless

This is a decidedly highly legible font very closely matching the Atkinson Hyperlegible Font.

univers grotesk

with the serifless capital I and double-storey lower case a, typograffic gets a similar face lift to complement its descending lower case f..

with..

upper case	from prior shape	to grotesk shape
G	toothed-serifless-hookless	toothless-rounded-serifless-hooked
I	serifed	serifless
J	descending-flat-hook-serifless	flat-hooked-serifless
Q	straight	(unchanged)

lower case	from prior shape	to grotesk shape
a	single-storey	double-storey
f	flat-hook-extended-crossbar-at-x-height	(unchanged)
j	flat-hook-serifed	flat-hook-serifless

Save for the dyslexic tuned glyphs, typograffic now more closely resembles its Grotesk roots.

Iota

has just a minor change..

with..

upper case	from prior shape	to Iota shape
B	standard-interrupted-serifless	(unchanged)
G	toothed-serifless-hookless	(unchanged)
I	descending-serifless	(unchanged)
J	descending-flat-hook-serifless	(unchanged)
P	open	(unchanged)
Q	straight	(unchanged)
R	straight-open	(unchanged)

lower case	from prior shape	to Iota shape
a	single-storey-serifless	(unchanged)
f	flat-hook-extended-crossbar-at-x-height	(unchanged)
j	flat-hook-serifed	flat-hook-serifless

Note: The capital I in the exhibit is the serifless glyph from the Iosevka web page—and not the glyph created for the font. Similarly, the lower case q for the three fonts is replaced by the unicode hook-tailed glyph.

All told though, typograffic differs from articulate by 5 glyphs and Iota from typograffic and articulate by 7 glyphs and 9 glyphs respectively. See if you can spot them :)
Note: iota has the descending capital I which is not represented in the screenshot.

i expect to be an outlier in my fondness for the iota typeface. But with the changes made to it’s predecessor fonts, the articulate and typograffic fonts should find a wider audience with their more familiar glyph sets.

Edit: Recently, i’ve been reading with the previous version of Iota with the serifed lower case j. It just feels more “right” with this typeface (to my eyes) despite my Grotesk leanings—aligning with my non-mirrored dyslexic rule, even though it still is a J. In this instance, the serifed separation of the dot distinguishes the lower case glyph from its descending-serifless upper case counterpart, especially at small font sizes. i am no neuroscientist but i surmise this reflects a visual cortex pattern (memory) expectation of glyph shapes while reading with a specific typeface, hence, the benefit of the contrasting outline—the distinction lessening the visual effort to determine the case of the word and the context it implies.

Edit: Further to the above remark, i have been switching between the sans serif and serifed lower case j versions of the articulate and typograffic fonts. On the one hand is the clean sans serif glyph vs the slightly more legible serifed glyph (despite the distinctive upper and lower case glyph shapes) . Not that it in any way is ugly. One is airier, the other ever a touch more balanced (in relation to its side bearing to leading characters)—a very personal visual bias. It is a tough call—and i am glad that both versions are available in the repos :)

readability

ranking order tightens up between the articulate and typograffic fonts with these changes. Before it was distinctly articulate first and a toss between typograffic and Iota. Now articulate and typograffic are a very very close one two with Iota remaining third on the podium—still a lovely typeface.

The crossing capital Q for the articulate font returns the familiar and distinct glyph. Similarly, the serifless lower case j is restored—albeit its dot loses a bit of separation with the loss of the serif at small font sizes.

The typograffic font gains the most in the readability scale with the return of the double-storey lower case a and the rounded-hooked capital G. The serifless capital I, often a readability issue with geometric fonts, differentiates itself against typograffic’s remaining glyph set.

Iota doesn’t make any gains in readability. It’s descending capital I is highly distinct but the thrust of the font with its open hookless capital G and single-storey lower case a for a more open font loses a few points for those with impaired vision—especially at small font sizes—whilst gaining a few (imo) with its clean minimalist geometry and unique yet understated flair. i adore this font.

For everyone else, the articulate and typograffic fonts offer two highly readable fonts with slightly different grotesk flavourings. (But you still might do well to give Iota a glance—i find it enticingly seductive :)

Note: This web font is a hybrid of the font trio—augmented with vertical-crossing capital Q and serifed lower case j for better readability with the lower resolution of desktop screens in general.

repos

The new e-reader fonts may be found on OneDrive under the font-trio folders within the Kindle and Kobo folders.

The j-serifless subfolder contains the fonts described above. The j-serifed subfolder retains the serifed lower case j for those who prefer its extra degree of legibility. The original trio of fonts remain available

As always, YMMV.

acknowledgement

while it has been referenced multiple times in prior font articles on this site, it goes without saying that none of this font exploration would have been possible without the generosity of the creator of Iosevka—both the font generation itself and the glyph screenshot exhibits taken from its home/customization page—and those involved with the opensource FontForge project.
