this topic will be short—a strong indicator that the dyslexic font variants presented on this site is coming to an end :)
When the dyslexic font exploration began, a word spacing of Space 2x was used for maximum word separation. This spacing in subsequent font generations narrowed to 1.667x 1.5x 1.333x and finally Space M with the introduction of the quasi-extended monospace fonts. This site currently uses Space M word spacing.
which is tighter still than Space M (which is the equivalent of Space 1.25x). To my eyes on 300 PPI ereaders, this feels a more natural word spacing whilst keeping a measure of dyslexic word separation—the visual line scan has a more even cadence with less of a jump to the next word. This appears to be resolution dependent, as i still find Space M on the site comfortable.
This works for me and presents a more “normal” page density. But depending on individual dyslexia, the wider word spacings may be preferable.
The repos now carry a set of fonts with Space 1.15x. The Emdash and Ellipsis have also been tightened to Space 2.15x widths for these fonts.
with the recent introduction of the groot font, i have for the Space 1.15x fonts, renamed the umu and upsilon fonts to mudra and tundra respectively—the lower case a for these two fonts is clealy distinguished in the font menu facsimiles.
These three fonts along with the mu font comprise my ereader font rotation. groot is the “flattened” typeface with only** the traditional lower case descenders g j p q y. mudra and tundra are the descending typefaces with their descending caps I J T Y and extended lower case f—differing only in their toothless double-storey and single-storey lower case a. The mu font sits between with its descending caps I J and extended lower case f. These four fonts all use the unique hookless capital G and straight Q.
Sometimes i like the clean line spacing emphasis the groot font presents. More often than not, it’s the more distinctive serifless descending capital I of the mu font. Other times, the flourish of the descending caps of the mudra and tundra fonts. As always, YMMV.
**After extended reading with the original groot typeface, the serifless capital I was replaced with the much more distinct and legible descending capital glyph.
The current ereader fonts may be found on OneDrive.
tightening the word spacing still further are the latest duet of grote and stria fonts with their distinctive asymmetric lower case t glyphs—stria with its hooked glyph and Atkinson Hyperlegible origins and grote with its angular hookless glyph as a departure towards a purer geometric serifless font (sans hooks and other glyph embellishments for a more open and minimalist typeface).
Optimal word separation is highly dependent on the individual reader—some still find the earlier fonts with 2x spacing works best for them. Meanwhile, font development on this site has gravitated towards narrower spacings coinciding with the adoption of quasi-proportional cell widths for the M W glyphs.
As the fonts represented here have evolved towards maximum air between adjacent glyphs and more geometric shapes, tightening of word spacing produces a more familiar page word density whilst still maintaining the needed cognitive separation—for these eyes, at least.
As always, YMMV.
