Quick Answer
A 15 minute speech is about 1,950 words at a conversational 130 words per minute. Depending on pace, plan for 1,500 to 2,400 words, which is roughly 6 to 10 double-spaced pages.
Fifteen minutes is enough to build a real argument with several supporting points. At 130 words per minute that is about 1,950 words, close to 8 double-spaced pages. It is also long enough that structure matters: without clear sections, listeners lose track of where you are.

Where 15-Minute Talks Are Used
- Conference paper presentations: Many academic conferences schedule 15 to 20 minute slots per paper, often with questions inside the slot. Check whether your time includes Q&A before you write.
- Sermons and homilies: Many services leave 12 to 20 minutes for the message, which puts 15 minutes near the middle.
- Internal deep dives: A project review or quarterly update in an all-hands meeting often gets a 15-minute slot.
- School assemblies and guest talks: Visiting speakers at schools are commonly asked for 15 minutes, which matches a young audience's attention span better than half an hour.
A 1,950-Word Structure
Break the talk into short sections and tell the audience when you move between them:
- Opening (about 200 words, 1.5 minutes): Hook, the question you will answer, and a one-line preview of the sections.
- Section one (about 450 words, 3.5 minutes): Context: what the audience needs to know for the rest to make sense.
- Section two (about 450 words, 3.5 minutes): Your main finding, idea, or argument, with the strongest evidence.
- Section three (about 450 words, 3.5 minutes): Implications, examples, or a counterargument and your answer to it.
- Close (about 400 words, 3 minutes): Summary of the three sections, the one takeaway, and next steps or an invitation to questions.
Slides, Notes, and Timing
- Slides: A common rule of thumb is one slide per one to two minutes, so 8 to 15 slides. Dense data slides need more time each; image slides need less.
- Script or notes: At nearly 2,000 words, reading word for word sounds flat. Many speakers write the full script to find the length, then present from an outline.
- Questions inside the slot: If the 15 minutes includes Q&A, script for 11 to 12 minutes, about 1,450 to 1,550 words.
