What is the recommended line length for readability?

Explanation:
Line length affects readability and how easily the eye moves from one line to the next. A range of about 45 to 90 characters per line provides a comfortable balance: lines aren’t so short that reading feels choppy, and not so long that tracking becomes tiring. Short lines, like 20–40 characters, break the flow with frequent wraps and can disrupt comprehension. Very long lines, such as 90–120 or 100–130 characters, make it harder to keep your place and increase strain, especially on smaller screens or with smaller text. In practice, aiming for a mid-range length and adjusting for font size and device helps maintain legibility across contexts.
