Say hello to Snapdeck social carousel

Snapdeck now has a 4:5 social carousel mode. 🎀
It's made for the formats we keep seeing across Instagram carousels, Threads image sets, LinkedIn swipe posts, and other social feeds. This is not a horizontal presentation squeezed into a vertical frame. It is designed from the start for the way people pause, swipe, save, and share in a feed.
We kept running into the same little problem ourselves: "This works as a presentation, but it feels too heavy for Instagram." Or, "This needs one more pass before it feels like card news." That extra cleanup sounds small, but it adds up. This update started from wanting to make that step lighter.
Why 4:5
Most presentations are 16:9. That works well when someone is sharing a screen, walking through a meeting, or exporting a PDF. Social card news is read in a very different moment. Someone might be on the subway, between tasks, or half-scrolling through a quick break.
In that setting, the first card needs to earn the pause, and the second card needs to earn the swipe. The middle cards should feel worth saving. The last card works best when it closes with one clear action instead of trying to say everything at once.
4:5 fits that rhythm nicely. It is tall enough for a mobile hierarchy, but not so tall that the card feels heavy. A headline, a few short lines, and a checklist or example can all sit comfortably inside the frame.
Card News, Not A Vertical Deck
The thing we cared about most was whether the output actually felt like card news, not just a vertical slide. ✨
When a presentation is simply resized, something usually feels off. The title still sounds like a deck title. The body is too long. Page numbers, progress indicators, presenter metadata, or footer labels stay on the page. In a social feed, those details rarely help. On a small screen, they slow the reader down and make the card feel less saveable.
So the 4:5 mode starts from a different prompt approach:
- cover cards use feed-readable hooks, not presentation titles
- the second card is a re-hook, not a table of contents
- each middle card carries one idea
- checklists, templates, before/after panels, and scripts become saveable structures
- page numbers, progress bars, watermarks, and presenter metadata are removed
From the outside, it may look like "one more aspect ratio." Inside the generation flow, each card has a different job.
Four Carousel Types
Not every carousel is trying to do the same thing. Some should read like a little magazine piece. Some should be saved like a tutorial. Some need to promote an event. Some should become a tiny playbook someone can screenshot and reuse.
So the current 4:5 carousel mode has four directions.
Magazine is for editorial people-and-insight stories. It uses large image zones, short claims, and clear takeaways.
Guide is for save-worthy tutorials. It favors mistake-to-fix arcs, before/after examples, checklists, and mini templates.
Event is for event and campaign promotion. It helps the viewer understand who it is for, why they should care, what the moment might feel like, and what to do next.
Playbook is for execution-oriented content. It turns decision rules, scripts, operating checklists, and do/don't structures into cards people can screenshot.
Even within the same 4:5 frame, the writing density, visual grammar, and final CTA should change depending on the job. Splitting these types out helped the results feel much less samey.
The Input Changes Too
When you select 4:5 on the home screen, the example prompts and description shift into carousel mode too. 🌿
Instead of starting from "make me a presentation," you see prompts like "Make an Instagram carousel explaining 5 morning habits that boost your productivity" or "Create a card-news carousel breaking down how compound interest grows your money over time." The starting point already helps you imagine a social output.
The style selection screen also switches from regular presentation styles to carousel-specific styles. The previews are vertical, and the hover motion hints at the next card in the swipe. We wanted the creation flow to feel like a carousel from the very beginning.
What We Tuned In The Engine
The 4:5 cards are generated around a 1080×1350 canvas. Since Instagram and other feed surfaces can slightly crop or mask the edges, important text and CTAs stay inside a safe zone.
Text density mattered a lot too. A carousel card does not get better by carrying more words. One card should do one job. It needs a strong headline, compact support copy, and a visible structure like a checklist, example, proof object, or template.
So the generation rules include mobile readability, safe zones, Snapdeck Sans, image placeholder handling, and strict removal of page chrome like slide numbers or progress indicators. Before a card is beautiful, it needs to be readable in a feed and editable inside Snapdeck.
What's Next
This update feels like Snapdeck growing a little wider than "a tool for presentations." The things people make now do not only live in meeting rooms. Product updates, hiring posts, event promotions, educational content, and personal branding pieces are often consumed on social platforms first.
Those pieces still need structure: the hook, the saveable middle, the final action. The 4:5 social carousel mode is our first step toward making that structure directly inside Snapdeck.
Now you can enter a topic, choose 4:5, pick the right carousel style, and start from a format that already understands the feed. We'll keep using it ourselves too, and keep shaping it into something prettier, lighter, and more useful. 💌
