Fonts designed for legibility and accessible reading
Families whose makers set out to make letters easier to tell apart: for low vision, beginning and struggling readers, and safety-critical displays.

Most typefaces aim for harmony: letters share shapes so that text looks even. Legibility-first designs deliberately trade some of that evenness for difference. If b is not simply a mirrored d, and capital I, lowercase l and the digit 1 each have their own silhouette, a reader has less to disentangle. That helps people with low vision, people who are learning to read, and anyone reading under stress or at a glance.
The features to look for are concrete. A zero that is slashed or dotted. A capital I with serifs and an l with a tail. An open, generously spaced design, since crowding makes letters harder to separate for many readers. A large x-height and unambiguous punctuation. Several families here were developed with a specific group of readers or a specific setting, and the note on each says what its record states about that.
A caution is in order. No font fixes reading difficulty on its own, and the evidence for typefaces aimed at dyslexia is mixed. Size, line length, spacing and contrast do at least as much. Treat these families as a sound starting point, then let the reader adjust the rest.
-
Atkinson Hyperlegible
Developed for readers with low vision: a slashed zero, a serifed capital I and a tailed l keep look-alikes apart; Regular and Bold with italics.
-
Atkinson Hyperlegible Next
The same slashed zero, barred capital I and curved-foot l, extended to seven weights with italics.
-
Lexend
Made to reduce visual stress in reading, first drawn with dyslexic and struggling readers in mind; nine upright weights.
-
Readex Pro
Extends the Lexend reading fonts to Arabic, with a Hyper Expansion axis that lets readers widen the space in and around letters.
-
Andika
Made for teaching reading, with single-story a and g like handwritten forms and open bowls; Regular and Bold with italics, with Cyrillic.
-
ABeeZee
A learning font for children: single-story a and g and round, even strokes close to the forms a child is taught to write; one weight with an italic.
Samples load a basic Latin subset of each family. Every family here carries an open license; its page states the terms and offers the original files.
Questions about fonts designed for legibility and accessible reading
Is there a font that helps with dyslexia?
Research has not shown that any typeface reliably does. Wider letter and word spacing, larger sizes and shorter lines have better support. Families with clearly distinct letters are a reasonable base to apply those settings to.
What makes letters easy to tell apart?
Different silhouettes for look-alike characters: a slashed zero, a serifed capital I, a tailed l, and a b that is not a mirrored d. The notes below mention such features where the record lists them.
Can I use these fonts in public-sector or commercial products?
Yes. They carry open licenses that allow commercial and institutional use, including embedding in apps and documents.
