When creating a transparency, what should be the limit of lines per page?

When creating a transparency for educational purposes, it's essential to maintain clarity and readability for the audience. Six lines per page is generally considered optimal because it allows for an effective balance between providing enough information and keeping the visual presentation uncluttered. This limit helps to ensure that students can easily absorb the content without being overwhelmed by too much text, which can lead to disengagement.

Having six lines allows for the inclusion of concise, impactful information while also giving enough space for visuals or highlighting important points. This format is conducive to instructional settings where the instructor can elaborate on each point without the audience being distracted by a crowded visual. The choice of six lines supports effective communication in teaching and enhances learning retention.
