One scene, every platform
Each social network wants a different shape, and posting a square image into a vertical story leaves ugly bars or harsh crops. The social post generator solves this by building your image at the exact ratio you choose before it ever renders. That means a clean feed post, a full bleed story and a wide ad can all share one idea without distortion. Our social media imagery guide covers how to plan a set.
Sizing for each format
Getting the ratio right is half the battle. A square fits most feeds, a tall nine by sixteen frame fills stories and reels, and a wide frame suits ad placements and link previews. Choosing the shape first lets the model compose for it, so your subject sits in the safe zone rather than getting clipped. The aspect ratio guide lists the exact numbers.
| Format | Aspect ratio | Where it shows |
|---|---|---|
| Feed post | 1:1 square | Instagram, Facebook |
| Story or reel | 9:16 tall | Stories, TikTok, Shorts |
| Portrait post | 4:5 upright | Instagram feed |
| Ad or link card | 16:9 wide | Banners, link previews |

Lock a color palette and style, then reuse it across formats so your grid looks intentional. Pair these visuals with marketing copy using ideas from the marketing imagery guide, or start from a layout in our social media templates. For one off scenes, the main generator gives you full freedom over every detail. Finish your posts by adding a logo or caption with the image overlay tool, building a YouTube thumbnail, or combining shots into a photo collage.
