The Deck Is Dead, Long Live the Phone

The Deck Is Dead

Long live the phone. Why mobile-first presentations are eating the landscape slide for breakfast.

Expo AI at IntDev, Seattle

The 16:9 landscape deck was built for a world of boardrooms, projectors, and captive audiences. That world is gone. Here is what replaced it.

Meetings are hybrid or async. The projector is optional, the phone is not.

Audiences scroll vertically. They always have. Landscape is the odd one out.

Attention is earned in 3 seconds, not 30 slides.

AI generates decks in minutes. The format is commoditized. The experience is not.

It is a competitive advantage. Portrait presentations are shareable, scrollable, and built for the device that never leaves the room.

Vertical video dominates every social platform. Presentations are next.

A phone deck gets forwarded. A PDF attachment gets ignored.

AI tools now generate portrait-native flows in seconds, not hours.

The best presentations in 2025 feel like content, not compliance.

The question is not whether your audience has a phone. The question is why you are still designing against it.

Not the projector. Not the PDF. The phone that is already in their hand.

Kill your next landscape deck. Start portrait.

Design for a swipe, not a click-through.

Share a link, not a file. Make it live.

The deck had a good run. The phone is just getting started.

Type a prompt. Get a flow worth sending — from blank page to shareable link in about sixty seconds.
