Story format
The story format is a display style for mobile phone screens: vertical, made up of individual image or video cards that are advanced by tapping. Posts in this format usually disappear from social networks again after 24 hours.
The story format is a particular way of showing content on a mobile phone. A post doesn’t consist of one long text, but of several short cards. Each card fills the screen completely in portrait orientation and shows a photo, a video, or a few lines of text. Tapping the right edge of the screen jumps to the next card, tapping the left edge goes back. If you do nothing, the cards play automatically one after another, usually for five to fifteen seconds each. This format became known through Snapchat in 2013, and shortly afterward Instagram, WhatsApp, Facebook, YouTube, and TikTok adopted it.
Why media outlets and companies rely on it
The reason is simply how people hold their phones. Almost everyone holds it vertically, not horizontally. A landscape video then only fills a small strip in the middle of the screen. The story format, by contrast, uses the entire surface and leaves no room for other content. That’s exactly why attention stays on the post longer.
There’s a second effect on top of that: many stories delete themselves after 24 hours. This time limit creates a slight pressure to look now rather than later. For companies, this is a tool for being seen regularly without filling the permanent profile page with trivial content. News outlets, too, are now building their reports as card stacks, because young readers spend their time there.
For investors, the format is economically interesting. Advertising can be inserted between the cards that looks just like the rest of the content. Meta, the company behind Instagram and Facebook, earns a significant portion of its revenue from this form of advertising. When Instagram introduced Stories in 2016, rival Snapchat noticeably lost user growth.
The structure of a card sequence
Technically, a story is an ordered list of media items. The app preloads the cards so that no waiting time occurs when tapping forward. Small progress bars sit above each post, one per card. This lets you immediately see how much is still to come. The aspect ratio is almost always 9:16, meaning significantly taller than wide.
Additional elements are layered on top of the images: text, stickers, polls, links, or music. These elements are not part of the photo itself, but separate layers. That’s why you can tap a poll and vote while the video keeps playing. It is precisely this interactivity that distinguishes a story from an ordinary video.
A common misconception is that Story and Reel are the same thing. A Reel is a single short video that remains permanently and is also suggested by the software to strangers. A Story, by contrast, is aimed primarily at one’s own followers and disappears again. Both are vertical in format, but their purpose differs.
From the schoolyard to the news page
In everyday life, this format is encountered mainly on Instagram, WhatsApp, and Snapchat. There, friends share photos that are gone again after a day. Sports clubs, musicians, and politicians also use it to show updates or behind-the-scenes glimpses. Anyone who posts a story themselves can later see a list of everyone who has viewed it.
The format also exists outside social networks. Google has created a variant for ordinary websites called Web Stories. News portals, shops, and recipe sites use it to recreate articles as card stacks. Such pages load quickly and sometimes appear prominently in Google search.
In business news, the term usually comes up in connection with advertising revenue. When a platform reports how many people view stories daily, it’s about advertising slots. And when programs using artificial intelligence automatically generate matching cards from a text, this format is also what’s meant.
