Frequently Asked Questions About Pitch Deck Design
How many fonts maximum in a deck?
2 max. 1 sans-serif body + 1 bold header.
Red/green color scheme—okay or risky?
Risky. 8% VCs colorblind. Use blue/orange/gray.
Should I use animations?
Yes—data reveal only. Page swipe = distraction.
Canva vs Figma—which better for VCs?
Figma. Canva templates scream “non-technical founder.”
What’s the optimal slide count?
12 slides. Investors spend 3:47 total time.
Whitespace percentage target?
40-50%. Crowded = amateur.
