Adaptive Typography

The practice of adjusting text presentation - font size, weight, line spacing, character spacing, contrast, and colour - automatically or semi-automatically in response to the user's current needs and context. Adaptive typography goes beyond static accessibility settings by reacting to real-time signals such as ambient light, device motion, reading distance, fatigue, or explicit user feedback, and is a primary mitigation strategy for situational visual impairments. For accessibility, well-designed adaptive typography can benefit low-vision users, dyslexic readers, older adults, and users of translated or information-dense content.
