# What is a slide deck? > **Slide deck:** A slide deck is a set of slides built around one purpose and meant to be presented or read in order. In business, the word also names the file itself, usually a PowerPoint document. - Source: https://ai-presentations.com/glossary/slide-deck/ - Updated: 21 October 2026 - Language: English - German version: https://ai-presentations.com/de/glossar/foliensatz/ Also called: deck, presentation deck A **slide deck** is a set of slides that belong together: one purpose, one audience, shown in order. In business, "deck" is also shorthand for the file itself, as in "send me the deck", and the file is usually a PowerPoint document. A **presentation** is the event in which you show it, although the word is often used for the file too. ## What a deck contains Business decks usually share the same parts: | Part | Its job | | ----------- | ---------------------------------------------------------- | | Title slide | Names the topic, the date and the audience | | Summary | Gives the answer or the ask up front | | Body | One message per slide, with the evidence | | Closing | Repeats the decisions or next steps, with owners and dates | | Appendix | Holds the backup material | The example is invented: a quarterly business review from a fictional software vendor to a customer. Slide 2 is its summary: outcomes first, in the customer's own numbers. 1. Kessler Bau and Lindhoven Site: a quarter of fewer delays 2. Site reports now arrive the same day, and rework is down by a third 3. Berlin has 64 weekly active users, Leipzig 17; Leipzig is the one to watch 4. Four of five Q3 commitments delivered 5. Three steps to full adoption before the renewal 6. Two things we need from you Read only the titles after the title slide and you get the whole story: - Site reports now arrive the same day, and rework is down by a third - Usage grew on every site; Leipzig is the one to watch - Four of five Q3 commitments delivered - Three steps to full adoption before the renewal - Two things we need from you ## Presentation deck or reading deck A deck is used in two ways, and each needs a different build. - **A presentation deck** is spoken. Slides carry a title and one visual, and the presenter supplies the explanation. - **A reading deck** is sent and read without a presenter, for example as a [pre-read](https://ai-presentations.com/glossary/pre-read/). Slides carry full-sentence titles and enough text to stand alone. Decide which one you are building before the first slide. A deck built for both tends to be too dense to present and too thin to read. ## How to build a good deck 1. **Start from the message,** not from the slides. Write the answer and the ask in two sentences. 2. **Write the titles first.** Titles that are full sentences and read as a storyline are the skeleton of the deck. Consultants call this a [ghost deck](https://ai-presentations.com/glossary/ghost-deck/). 3. **Give each slide one message** and one visual that proves it. 4. **Keep the main part short** and move detail to the [appendix](https://ai-presentations.com/glossary/appendix/). The guide on [how many slides](https://ai-presentations.com/guides/how-many-slides/) helps you size it. 5. **End on the ask:** decisions, owners and dates. 6. **Test it by reading the titles aloud.** If the story does not hold, fix the titles before the slides. ## Typical mistakes - **Opening PowerPoint with an empty slide** and no storyline. - **Topic titles** such as "Results" instead of statements. - **One deck for every audience.** An investor, a customer and a team need different decks, even from the same material. - **Too many slides** for the time available. - **No ask at the end.** The AI first shows a page plan with one card per page, which you can edit or approve before it builds the deck, and you can export the finished deck as a PowerPoint file. ## Frequently asked questions ### What is the difference between a slide deck and a presentation? A slide deck is the file: the set of slides. A presentation is the event in which you show it, although many people use the word for the file as well. A deck can also be read on its own, without anyone presenting it. ### How many slides should a deck have? As many as the message needs and the time allows, and no more. Size the main part to the speaking time and move supporting detail to an appendix. ### What is a pitch deck? A pitch deck is a short slide deck that a founder uses to present a business to investors, usually covering the problem, the solution, the market, traction, the team and the ask. The same term is used for decks that pitch a product or service to a customer. ### What is the difference between a presentation deck and a reading deck? A presentation deck is spoken, with little text on each slide. A reading deck is sent and read without a presenter, so its slides have full-sentence titles and enough text to stand alone. ## Related pages - [Storyline](https://ai-presentations.com/glossary/storyline/): A storyline is the logical chain of messages that carries a presentation from its opening to its conclusion.
