The fastest way to learn how to make a good PowerPoint presentation is to work through a fixed order: pin down the audience and a one-sentence goal, build the outline before opening a single slide, cut each slide to one idea, write headline-style titles, fix the type size, fix the contrast, trade bullet lists for visuals, keep the layout consistent, check accessibility, then rehearse and time it. The ten steps below cover each one with a before-and-after example, a table of common mistakes, and two real reference points worth knowing: Guy Kawasaki’s 10/20/30 rule and Microsoft’s own accessibility guidance for PowerPoint.
Step 1: Know the Audience and State the Goal in One Sentence
Before opening PowerPoint, write down who is in the room and what they should decide or do after the talk ends. “Update the team on Q3” is a topic, not a goal. A goal names the decision: “the committee approves moving the warehouse project into phase two.”
Before: Slide one reads “Agenda: Company Update.” After: Slide one reads “Decision needed today: approve phase two of the warehouse project.” Every slide that follows can now be tested against whether it helps that decision.
Step 2: Build the Outline Before Touching a Slide
Write the talk first, in a document or on paper: the opening line, three to five main points, and the close. Slides should illustrate an argument that already holds up on its own, not generate talking points as they are built inside PowerPoint.
This is also the thinking behind Guy Kawasaki’s 10/20/30 rule, first published on his blog on 30 December 2005: a pitch deck should run to about ten slides, last no more than twenty minutes, and use no font smaller than thirty points, because, in his words, “a normal human being cannot comprehend more than ten concepts in a meeting.” Outlining first is what makes a ten-slide limit realistic instead of a trap. It is also how to make a better PowerPoint presentation without adding a single slide: cutting the outline down before design starts removes far more clutter than editing slides after the fact.
Before: Twenty-two slides built live while drafting the talk in PowerPoint. After: A nine-point outline written first, then one slide per point.
Step 3: One Idea Per Slide
A slide with five sub-bulleted reasons is five slides trying to share one title. Split it. Each slide should be able to stand alone as a single claim, with everything on it supporting that one claim.
Before: One slide titled “Reasons Churn Increased” with five bulleted causes and sub-bullets under each. After: Five slides, each with one cause stated as the title and a single supporting visual or line underneath.
Step 4: Write Headline-Style Slide Titles
A slide title should state the point, not label the category. “Market Overview” tells the audience nothing; it just names a folder. A headline-style title tells them what to take away even if they read nothing else on the slide.
Before: “Budget Summary.” After: “Marketing spend needs to shift from print to paid social.” The second version works as a standalone sentence a reader could repeat back from memory.
Step 5: Use Readable Type Sizes
Text that is comfortable to read on a laptop screen is often unreadable from the back of a conference room. Kawasaki’s rule puts the floor at thirty points for exactly that reason: it forces a presenter to cut text down to what actually matters, rather than reading dense paragraphs aloud.
Before: Body text at 14 points, six lines deep, in a shrunk text box. After: One line at 28 to 32 points, with the rest of the explanation spoken, not displayed.
Step 6: Get Contrast and Color Right
Low contrast between text and background is the single most common reason slides look unreadable on a projector, even when they look fine on a laptop. Dark gray text on a light gray background, or white text on a pale yellow background, fails well before anyone notices on their own screen.
Before: Light gray text (#999999) on a white background. After: Near-black text (#1a1a1a) on white, or white text on a dark navy background. Running the colors through a tool such as SlideMaker’s contrast checker before presenting catches combinations that fail on a projector, not just on a laptop screen.
Step 7: Replace Bullet Lists With Visuals
Richard Mayer’s research on multimedia learning, applied directly to slide design in UC San Diego’s evidence-based presentation design guidance, backs this up with more than opinion. The redundancy principle found that people learn better from graphics paired with spoken narration than from graphics, narration, and the same words printed on the slide at the same time; reading and listening to identical text at once adds effort instead of reducing it. The signaling principle adds that highlighting the one organizing idea, such as with an arrow or a single bold label, helps an audience follow a complex diagram faster than a wall of bullets does.
Before: A slide with six bullet points restating the spoken script word for word. After: A single chart showing the trend, with the presenter narrating the explanation aloud instead of reading it off the screen.
Step 8: Keep Layout Consistent Slide to Slide
Titles that jump between the top-left and center, fonts that change between sections, and logos that move position all cost attention the audience should be spending on the content. A consistent template, one set of fonts, and a fixed logo position let the eye settle once and stay on the message.
Before: Three different title fonts and two logo positions across one 12-slide deck, left over from slides copied out of older files. After: One master layout applied to all 12 slides, with title position, font, and logo fixed throughout.
Step 9: Make the Deck Accessible
Microsoft’s own support documentation on making PowerPoint presentations accessible lays out specific, testable steps: write a unique, descriptive title on every slide so screen reader users can scan the title list to navigate; add brief alt text to images and charts; use sans-serif fonts at 18 points or larger; and avoid putting information only in a table when a short paragraph or a built-in list would work better for a screen reader. PowerPoint’s built-in Accessibility Checker, under the Review tab, flags most of these automatically before a deck goes out.
Before: A chart pasted in with no alt text and a slide titled “Slide 7.” After: The same chart with a two-sentence alt description of the trend it shows, on a slide titled “Shipping costs fell after the carrier switch.”
Step 10: Rehearse It and Time It
Kawasaki’s rule also sets the time budget at twenty minutes, on the logic that a shorter talk leaves room for questions and discussion instead of eating the whole meeting. Reading a deck aloud once, with a timer running, catches the slides that take three times longer to explain than they looked like they would on the page.
Before: A 20-slide deck never read aloud before the meeting, running 38 minutes against a 20-minute slot. After: The same deck timed in rehearsal, trimmed to 14 slides, finishing at 19 minutes with time left for questions.
Common Mistakes That Undercut a Good PowerPoint Presentation
Most weak decks fail for a handful of repeat reasons. The table below lines up the mistake against the fix from the steps above.
| Mistake | Why it fails | Fix |
|---|---|---|
| Writing the full script as bullet text | Audience reads ahead instead of listening; violates the redundancy principle | Cut to a headline title, speak the detail aloud (Step 7) |
| No stated goal for the talk | Every slide gets judged by gut feeling instead of a standard | Write the one-sentence goal first (Step 1) |
| Slide count decided after the deck is built | Leads to padding or last-minute cutting under pressure | Outline first, then cap at what the outline needs (Step 2) |
| Low-contrast color palette | Fails on a projector even when it looks fine on a laptop | Check contrast before presenting (Step 6) |
| Generic slide titles like “Overview” | Tells the audience nothing to remember | Rewrite titles as headline statements (Step 4) |
| Never rehearsed with a timer | Talk runs long, cuts into questions or the next meeting | Read it aloud once, timed, before presenting (Step 10) |
| Missing alt text and generic slide titles for screen readers | Locks out audience members using assistive technology | Follow Microsoft’s accessibility checklist (Step 9) |
Where an AI Presentation Maker Helps a Good PowerPoint Presentation, and Where It Does Not
An AI presentation maker is genuinely useful for the mechanical part of the job: turning a topic, a set of notes, or an existing document into a structured first draft. On SlideMaker, that means typing a topic or pasting notes or an outline, or uploading a PDF, DOCX, or TXT file; the tool plans an outline, picks slide types such as bullet slides, comparisons, timelines, and charts, writes the content, and adds images. Length options from Concise (6 to 8 slides) to In-Depth (13 to 15 slides) give a starting point close to Kawasaki’s ten-slide range without a blank document to stare at.
That first draft buys back time for the three steps that benefit most from it: Step 1 (deciding the real audience and goal), Step 2 (shaping the outline around that goal), and Step 10 (rehearsing and timing the result). A detailed walkthrough of turning notes into a working draft is in the guide on how to make professional slides with AI, and a side-by-side comparison of a generated-and-edited deck against a deck built from scratch in desktop software is in the SlideMaker vs. PowerPoint comparison.
What an AI presentation maker cannot do is judge the actual room: whether the finance committee responds better to a number or a story, whether a joke will land, or how a specific stakeholder tends to interrupt with questions. It also cannot rehearse for a presenter. Those two judgment calls, audience fit and practiced delivery, stay a human job no matter which tool builds the slides.
Frequently Asked Questions About Making a Good PowerPoint Presentation
What is the fastest way to make a good PowerPoint presentation?
Write the one-sentence goal and the outline before opening PowerPoint, keep one idea per slide, and rehearse with a timer. Those three habits fix most weak decks on their own.
How many slides should a good PowerPoint presentation have?
Guy Kawasaki’s widely cited 10/20/30 rule suggests around ten slides for a pitch-style talk, but the right number is however many the outline actually needs; padding to hit a round number, or cramming to stay under one, both work against the goal.
What font size makes a PowerPoint presentation easy to read?
Kawasaki’s rule sets a floor of thirty points for body text; Microsoft’s accessibility guidance recommends at least 18 points for readability with assistive technology. Either way, if text needs to shrink to fit, it belongs in the script, not the slide.
How do you make a PowerPoint presentation accessible?
Give every slide a unique, descriptive title, add brief alt text to images and charts, use sans-serif fonts at 18 points or larger, and run PowerPoint’s built-in Accessibility Checker before sending the file out, per Microsoft’s own support documentation.
Can an AI presentation maker make a great PowerPoint presentation on its own?
It can produce a structured, well-organized first draft from a topic or a document, which covers most of the outline and design work. It cannot decide who the audience really is or rehearse the talk, so those two steps still need a person.
