Which statement is NOT recommended for legibility in printed textbooks?

• A. Use serif fonts for body text
• B. Use 6 point font
• C. Appropriate size 12–14 pt
• D. High contrast

Answer: (B)

Legibility in printed textbooks hinges on choosing typefaces and sizes that let the eye move easily across lines and avoid strain. A 6 point font is far too small for body text; it makes individual letters hard to distinguish, slows reading, and increases errors, especially in longer passages. That’s why it’s not recommended. In contrast, serif fonts for body text are a common choice because the decorative strokes at the ends of letters help guide the eye along the line. An appropriate size, around 12–14 pt, is comfortable for most readers and page layouts. High contrast, such as dark text on a light background, makes characters stand out clearly and reduces visual fatigue. So, the statement about using 6 point font goes against these readability practices, while the other points support legibility.
