What is a key message?
Key message: A key message is the single idea you want your audience to remember and act on after a presentation, a section or a slide, stated in one sentence.
A key message is the single idea you want your audience to remember and act on after a presentation, a section or a slide, stated in one sentence. If they forget everything else, this is what should stay. It is the one idea of the whole presentation, while the so what belongs to a single fact.
A deck has key messages on three levels, and each level supports the one above:
- Presentation: one message for the whole deck.
- Section: one message for each part.
- Slide: one message for each slide, written as its action title.
Example
The board update example on this page opens its executive summary with the key message of the whole presentation: what happened and what the Board is asked to do.
The sentence has a result (revenue up 18%, a record margin) and an ask (approve the Rotterdam hub). Everything after it in the deck exists to support one of the two.
How to write one
- Start from the audience's decision. What should these people decide, believe or do when you finish?
- Write one sentence with a subject, a verb and a consequence. A topic such as “Our Q3 results” is not a message.
- Test it. Could you say it in one breath? Could someone who heard only that sentence act on it?
- Say it twice. Open with it and return to it at the close. Every section title should support it.
- Cut what does not support it. Material that supports nothing goes to the appendix.
Typical mistakes
- A topic instead of a sentence. “Q3 results” tells nobody what to remember.
- Three key messages. If you have three, you have three presentations or one message with three supporting arguments. Name the one.
- No ask. A message that does not say what should happen next stays interesting but changes nothing.
- Burying it at the end. An audience that knows where you are heading follows the evidence more easily.
- Writing for yourself. Use the audience's words and their stakes, not internal jargon.

The key message answers the so what for the whole presentation. The elevator pitch is the key message said out loud to someone who has little time. The pyramid principle puts the key message at the top and the supporting arguments beneath it.
FAQ
Frequently asked questions
How long should a key message be?
One sentence, short enough to say in one breath. If it needs two sentences, the second is usually a supporting argument or the ask, and it belongs beneath the message, not in it.
What is the difference between a key message and a key takeaway?
In practice the terms are interchangeable. Some people use key message for what the speaker wants to say and key takeaway for what the audience should remember. Write them so that both say the same thing.
How many key messages can a presentation have?
One per presentation, one per section and one per slide. Several messages at the same level compete with each other, and the audience remembers none of them.
Is the key message the same as the title of the presentation?
Usually not. A title names the subject, while the key message states the conclusion. They coincide only when the title is itself a sentence that carries the result and the ask.
