Readability is the ease with which a
reader can
understand a
written text. The readability of a particular text depends on content (for example, the complexity of its
vocabulary and
syntax) and
typography (for example, its
font size,
line height, and
line length). Researchers have used various factors to measure readability, such as
- Speed of perception
- Perceptibility at a distance
- Perceptibility in peripheral vision
- Visibility
- Reflex blink technique
- Rate of work (e.g., reading speed)
- Eye movements
- Fatigue in reading
