Slide Design Rules
Typography
| Element | Size (1920x1080) | Rule |
|---|---|---|
| Slide title | 48-72px | Max 6 words |
| Key stat/number | 96-144px | One per slide, when applicable |
| Body text | 24-32px | Max 6 bullet points |
| Caption/source | 16-20px | Cite data sources |
| Font | Sans-serif only | Inter, Helvetica, SF Pro, or similar |
The 1-6-6 Rule
- 1 idea per slide
- 6 words max per bullet
- 6 bullets max per slide
If you need more text, you need more slides.
Color
| Element | Guideline |
|---|---|
| Background | Dark (navy, charcoal) OR clean white — pick one, commit |
| Accent color | ONE brand color for emphasis |
| Text | White on dark, or dark grey (#333) on light |
| Charts | 2-3 colors max, your brand color = "you" |
| Avoid | Gradients on text, neon colors, more than 3 colors |
Layout
| Rule | Why |
|---|---|
| Consistent margins (80-100px) | Professional, clean |
| Left-align text (never center body text) | Easier to scan |
| One visual per slide | Focus attention |
| Slide numbers | Helps investors reference specific slides |
| Logo in corner | Subtle brand reinforcement |
Slide-by-Slide Visual Guide
1. Title Slide
belt app run infsh/html-to-image --input '{
"html": "<div style=\"width:1920px;height:1080px;background:#0f0f23;display:flex;align-items:center;justify-content:center;font-family:system-ui;color:white;text-align:center\"><div><h1 style=\"font-size:80px;font-weight:900;margin:0\">DataFlow</h1><p style=\"font-size:32px;opacity:0.7;margin-top:16px\">Automated reporting for data teams</p><p style=\"font-size:22px;opacity:0.5;margin-top:40px\">Seed Round — Q1 2025</p></div></div>"
}'
2. Problem Slide
One big number + one sentence.
belt app run infsh/html-to-image --input '{
"html": "<div style=\"width:1920px;height:1080px;background:#0f0f23;display:flex;align-items:center;padding:100px;font-family:system-ui;color:white\"><div><p style=\"font-size:24px;color:#f59e0b;text-transform:uppercase;letter-spacing:3px;margin:0\">The Problem</p><h1 style=\"font-size:144px;margin:20px 0;font-weight:900;color:#f59e0b\">12 hrs/week</h1><p style=\"font-size:36px;opacity:0.8;line-height:1.4\">The average data analyst spends 12 hours per week<br>building reports manually</p><p style=\"font-size:20px;opacity:0.4;margin-top:30px\">Source: Forrester Research, 2024</p></div></div>"
}'
5. Market Size (TAM/SAM/SOM)
Use concentric circles, not pie charts:
belt app run infsh/python-executor --input '{
"code": "import matplotlib.pyplot as plt\nimport matplotlib\nmatplotlib.use(\"Agg\")\n\nfig, ax = plt.subplots(figsize=(19.2, 10.8))\nfig.patch.set_facecolor(\"#0f0f23\")\nax.set_facecolor(\"#0f0f23\")\n\ncircles = [\n (0, 0, 4.0, \"#1e1e4a\", \"TAM\\n$50B\", 40),\n (0, 0, 2.8, \"#2a2a5a\", \"SAM\\n$8B\", 32),\n (0, 0, 1.4, \"#818cf8\", \"SOM\\n$800M\", 28)\n]\n\nfor x, y, r, color, label, fontsize in circles:\n circle = plt.Circle((x, y), r, color=color, ec=\"#333366\", linewidth=2)\n ax.add_patch(circle)\n ax.text(x, y, label, ha=\"center\", va=\"center\", fontsize=fontsize, color=\"white\", fontweight=\"bold\")\n\nax.set_xlim(-5, 5)\nax.set_ylim(-5, 5)\nax.set_aspect(\"equal\")\nax.axis(\"off\")\nax.text(0, 4.8, \"Market Opportunity\", ha=\"center\", fontsize=36, color=\"white\", fontweight=\"bold\")\nplt.tight_layout()\nplt.savefig(\"market-size.png\", dpi=100, facecolor=\"#0f0f23\")\nprint(\"Saved\")"
}'
7. Traction Slide
Show growth, not just numbers. Up-and-to-the-right chart.
belt app run infsh/python-executor --input '{
"code": "import matplotlib.pyplot as plt\nimport matplotlib\nmatplotlib.use(\"Agg\")\n\nfig, ax = plt.subplots(figsize=(19.2, 10.8))\nfig.patch.set_facecolor(\"#0f0f23\")\nax.set_facecolor(\"#0f0f23\")\n\nmonths = [\"Jan\", \"Feb\", \"Mar\", \"Apr\", \"May\", \"Jun\", \"Jul\", \"Aug\"]\nrevenue = [8, 12, 18, 28, 42, 58, 82, 120]\n\nax.fill_between(range(len(months)), revenue, alpha=0.3, color=\"#818cf8\")\nax.plot(range(len(months)), revenue, color=\"#818cf8\", linewidth=4, marker=\"o\", markersize=10)\nax.set_xticks(range(len(months)))\nax.set_xticklabels(months, color=\"white\", fontsize=18)\nax.tick_params(colors=\"white\", labelsize=16)\nax.set_ylabel(\"MRR ($K)\", color=\"white\", fontsize=20)\nax.spines[\"top\"].set_visible(False)\nax.spines[\"right\"].set_visible(False)\nax.spines[\"bottom\"].set_color(\"#333\")\nax.spines[\"left\"].set_color(\"#333\")\nax.set_title(\"Monthly Recurring Revenue\", color=\"white\", fontsize=32, fontweight=\"bold\", pad=20)\nax.text(7, 120, \"$120K MRR\", color=\"#22c55e\", fontsize=28, fontweight=\"bold\", ha=\"center\", va=\"bottom\")\nax.text(7, 112, \"15x growth in 8 months\", color=\"#22c55e\", fontsize=18, ha=\"center\")\nplt.tight_layout()\nplt.savefig(\"traction.png\", dpi=100, facecolor=\"#0f0f23\")\nprint(\"Saved\")"
}'
8. Competition Slide
Never use a feature matrix against competitors. Use a 2x2 positioning map.
# See the competitor-teardown skill for positioning map generation
belt app run infsh/python-executor --input '{
"code": "import matplotlib.pyplot as plt\nimport matplotlib\nmatplotlib.use(\"Agg\")\n\nfig, ax = plt.subplots(figsize=(19.2, 10.8))\nfig.patch.set_facecolor(\"#0f0f23\")\nax.set_facecolor(\"#0f0f23\")\n\ncompetitors = {\n \"Us\": (0.6, 0.7, \"#22c55e\", 300),\n \"Legacy Tool\": (-0.5, 0.5, \"#6366f1\", 200),\n \"Startup X\": (0.3, -0.4, \"#6366f1\", 200),\n \"Manual Process\": (-0.6, -0.6, \"#475569\", 150)\n}\n\nfor name, (x, y, color, size) in competitors.items():\n ax.scatter(x, y, s=size*5, c=color, zorder=5, alpha=0.8)\n weight = \"bold\" if name == \"Us\" else \"normal\"\n ax.annotate(name, (x, y), textcoords=\"offset points\", xytext=(15, 15), fontsize=22, color=\"white\", fontweight=weight)\n\nax.axhline(y=0, color=\"#333\", linewidth=1)\nax.axvline(x=0, color=\"#333\", linewidth=1)\nax.set_xlim(-1, 1)\nax.set_ylim(-1, 1)\nax.set_xlabel(\"Manual ← → Automated\", fontsize=22, color=\"white\", labelpad=15)\nax.set_ylabel(\"Basic ← → Advanced\", fontsize=22, color=\"white\", labelpad=15)\nax.set_title(\"Competitive Landscape\", fontsize=32, color=\"white\", fontweight=\"bold\", pad=20)\nax.tick_params(colors=\"#0f0f23\")\nfor spine in ax.spines.values():\n spine.set_visible(False)\nplt.tight_layout()\nplt.savefig(\"competition.png\", dpi=100, facecolor=\"#0f0f23\")\nprint(\"Saved\")"
}'
9. Team Slide
# Generate professional team headshots/avatars
belt app run falai/flux-dev-lora --input '{
"prompt": "professional headshot portrait, person in business casual attire, clean neutral background, warm studio lighting, confident friendly expression, corporate photography style",
"width": 512,
"height": 512
}'
Layout: Photos in a row with name, title, and one credential each.
| Person | Format |
|---|---|
| CEO | Name, title, "Ex-[Company], [credential]" |
| CTO | Name, title, "Built [thing] at [Company]" |
| Others | Name, title, one relevant credential |
Max 4 people on the team slide. More = unfocused.
Chart Guidelines
| Chart Type | Use For | Never Use For |
|---|---|---|
| Line chart | Growth over time (traction) | Comparisons between categories |
| Bar chart | Comparing amounts | Time series (use line) |
| Concentric circles | TAM/SAM/SOM | Anything else |
| 2x2 matrix | Competitive positioning | Feature comparison |
| Single big number | Key metric highlight | Multiple metrics |
| Pie chart | NEVER | Anything (hard to read, unprofessional) |
Chart Design Rules
| Rule | Why |
|---|---|
| Max 2 colors per chart | Clarity |
| Your company = green or brand color | Positive association |
| Label directly on chart | No separate legend needed |
| Remove gridlines or make very subtle | Reduce clutter |
| Start Y-axis at 0 | Don't mislead |
| Cite data sources | Credibility |
What Investors Look For
| Slide | Investor's Real Question |
|---|---|
| Problem | "Is this a real problem people pay to solve?" |
| Solution | "Is this 10x better than the status quo?" |
| Market | "Is this big enough to matter?" |
| Traction | "Is this actually working?" |
| Team | "Can these people execute?" |
| Ask | "Is this a reasonable deal?" |
Common Mistakes
| Mistake | Problem | Fix |
|---|---|---|
| Too many slides (20+) | Loses attention, unfocused | Max 12-15 slides |
| Wall of text | Nobody reads it | 1-6-6 rule: 1 idea, 6 words, 6 bullets |
| Feature comparison table vs competitors | Looks defensive | Use 2x2 positioning map |
| Pie charts | Hard to read, unprofessional | Use bar charts or big numbers |
| No data sources cited | Looks made up | Always cite sources |
| Team slide with 8+ people | Unfocused | Max 4, focus on relevant experience |
| Inconsistent design | Looks amateur | Same colors, fonts, margins on every slide |
| No "The Ask" slide | Investor doesn't know what you want | State amount, use of funds, timeline |
| Vanity metrics | "1M visits" means nothing without conversion | Show revenue, active users, retention |
| Too much product demo | This is a business pitch, not a demo | Max 2 slides on product, focus on business |
