What is the recommended line spacing for readability?

• A. 120-145% of the size
• B. 80-100% of the size
• C. 150-170% of the size
• D. 100-110% of the size

Answer: (A)

Line spacing, or leading, is the vertical space between lines of text. It matters because it gives the eyes room to move from the end of one line to the start of the next, reducing crowding and fatigue.

For body text, a line spacing of about 120% to 145% of the font size is typically recommended. This range provides enough white space to guide the reader smoothly through the text without breaking the reading rhythm. If the spacing is too tight (80–100%), lines feel cramped, making it harder to track from one line to the next. If spacing is too large (150–170%), the text can feel disjointed and slow the reading flow. So the best choice is a line spacing around 120% to 145% of the font size.
