What is the purpose of the 7x7 rule in PPT design?

• A. There should be no more than seven slides per presentation.
• B. There should be no more than seven words per line.
• C. There should be no more than seven images per slide.
• D. There should be no more than seven words per line and no more than seven lines per slide.

Answer: (D)

The essence is keeping slide content concise and readable to maintain audience focus. The 7x7 rule is a guideline that helps you avoid clutter by limiting how much text a slide contains. When you keep no more than seven words per line and no more than seven lines per slide, you create slides that are quick to scan and easy to digest while you speak. This encourages using short phrases, bullet points, and supporting visuals rather than long sentences or blocks of text, which reduces cognitive load for the audience and keeps them following your message. The other options miss one or both parts of this balance—focusing on total slide count, or on words per line or images per slide in isolation—whereas the complete rule combines both word count and line count to preserve clarity.
