What is the maximum group size for effective use of flip charts?

The maximum group size for effective use of flip charts is considered to be around 40 participants. This size allows for a manageable group, where participants can engage in discussion and activities while still being able to see and interact with the flip charts clearly. When groups exceed this number, it may become difficult for everyone to see the materials, and some participants may feel less inclined to contribute, thus hindering the overall effectiveness of the presentation or the interaction that the flip charts are meant to facilitate. Maintaining a group size around 40 ensures that the dynamics remain productive, with enough space for interaction and learning, without overwhelming the instructor or the resources being used.
