A starting point, with room to adjust
The ADHD reading preset selects Lexend, a little extra letter and word spacing, a line width of about 60 characters, the reading ruler and bold-first text at 30%. You can change anything afterward. Settings save in this browser; your text does not.
What the research says
A large online study of adult readers, not specifically ADHD, found that the best font differed from person to person, and preference did not predict performance: Wallace S. et al. (2022), ACM TOCHI 29(4). This supports trying different layouts rather than assuming that one font suits everyone.
Reading with Diversity in Mind: Pupillometry and Typography Towards Inclusive Design for ADHD Readers (2026), CHI extended abstract reports a small in-lab study of readers with and without ADHD. It found differences between groups in how font and size related to reading, and participants asked for customizable, distraction-free reading interfaces. It is an early-stage poster, not proof that any font helps.
Fonts to compare
- Lexend: wide, open letter shapes and a variable weight range. It is the preset’s starting font.
- Atkinson Hyperlegible: distinct shapes for similar characters such as I, l and 1.
- OpenDyslexic: heavier bottoms and distinctive letter shapes.
- System sans-serif: your device’s familiar interface font. Use it in your usual app as a comparison with the three fonts in this converter.
Compare the same passage at similar sizes. Comfort is a personal preference, and a preferred appearance does not establish a performance benefit.
