Presentation Slide Design Guidelines

These guidelines apply to all presentation tools and formats.

1. Outline First — Mandatory

You MUST draft a structured outline before creating any slides. Do NOT skip this step. A presentation is a narrative, not a document. Write a markdown outline that captures:

• The core message — one sentence the audience should remember
• The narrative arc — setup, tension/problem, resolution/insight, takeaway
• Key transitions between sections

Present this outline to the human and wait for approval before proceeding. Do not create slides until the human has reviewed and approved the outline. Adapt the structure to fit the topic — there is no single correct format. Example:

# Outline: [Presentation Title]

**Core message:** [One sentence]

## 1. Opening — Hook
- [Surprising fact, question, or story]

## 2. Problem / Context
- [What challenge are we addressing?]

## 3. Key Insight / Solution
- [Main idea, 2-3 sub-points]

## 4. Evidence / Demo
- [Data, examples, or demonstration]

## 5. Takeaway / Call to Action
- [What should the audience do or remember?]

2. Minimize Text — Ruthlessly

Slides are a visual aid, not a script. The presenter speaks; slides support.

Absolute maximum: 10 words per slide. The best slides have zero to three words. Headlines and short phrases only — never sentences. If you need full sentences, put them in speaker notes.

Use short headlines that state the takeaway, not a topic label.

• Weak: "Q3 Sales Results"
• Strong: "Sales up 40%"

Never put paragraphs or long bullet lists on slides. If a slide has more than two lines of text, rethink it.

One idea per slide. If a slide makes two points, split it.

3. Visuals Over Text

Show, don't tell. Images, diagrams, and charts communicate faster than words. When you can replace text with a visual, always do it.

Use full-bleed images. If a slide has one image, it should fill the entire slide. A small centered image with empty space looks unfinished. Use overlay text sparingly.

Download product logos and relevant images from the internet when they would strengthen the slide. Prefer official brand assets over arbitrary web results.

Ask the human for screenshots if they would help illustrate a point — screenshots of UIs, demos, dashboards, or workflows are often more effective than any diagram you could generate. It's very good practice to ask.

Replace bullet lists with visual layouts — cards, columns, or icons with short labels side by side.

NEVER create boxes that contain only text. Every box, card, or container on a slide MUST include at least one image, emoji, icon, or graphic element alongside any text. A box with just a heading or label and nothing visual is an antipattern — always pair it with a relevant visual. Exceptions exist but are rare.

Use diagrams for processes, relationships, and architecture. Use charts for data, with headlines that state the takeaway.

4. Control Attention

Reveal content progressively. Don't show everything at once — use incremental builds so each point appears when the presenter discusses it.

One visual focus per slide. Use size, color, or position to create a clear focal point. Grey out elements that aren't the current focus.

5. Design for Clarity

• Consistent styling. One color palette, one font family, one layout grid throughout.
• Large fonts. Body text minimum 24pt, headlines 36pt+. If text must shrink to fit, there's too much text.
• High contrast. Dark on light or light on dark.
• White space. Empty space directs attention — don't fill every corner.
• 1-2 accent colors against a neutral background.
• No clutter. Remove decorative elements, unnecessary logos on every slide, and ornamental borders.
• Left-align text. Easier to scan than centered.

6. Structure and Pacing

• Start with a hook — surprising fact, question, or image. Not an agenda slide.
• Use section dividers — simple slides with just a section title for mental breaks.
• End with a clear takeaway — restate the core message. Avoid generic "Thank you" or "Questions?" slides.
• Keep it short. Fewer slides than you think. Cut anything that doesn't directly support the core message.
