How many strong arguments should a 3-5 minute speech typically include?

In a 3-5 minute speech, including two or three strong arguments is generally the most effective approach. This timeframe doesn't allow for an extensive exploration of multiple points, so focusing on two or three arguments enables the speaker to elaborate adequately on each, providing sufficient detail and supporting evidence. This depth of discussion helps to engage the audience and ensures that the message is clear and memorable.

Having too few arguments might not provide enough substance to persuade the audience, while including four or more arguments could lead to superficial treatment of each point, ultimately making the speech feel rushed and unfocused. The goal is to strike a balance between thoroughness and conciseness, allowing the speaker to create a compelling narrative that captures and maintains the audience's attention throughout the brief duration of the speech.
