Start with shape, not a random pixel number
Social platforms display the same creative in different containers. A vertical image can work well in a phone feed but be awkward as a profile banner; a wide banner can look tiny in a square grid. The first decision should be the aspect ratio, followed by the exact pixel dimensions required by the destination.
The social media kit generator can create multiple platform versions from a source image using presets. For one-off work, image resize and image crop provide more direct control over the frame.
Useful starting ratios
| Asset shape | Ratio | Common use |
|---|---|---|
| Square | 1:1 | Profile grids, product tiles, avatars |
| Portrait feed | 4:5 | Mobile feed posts |
| Full vertical | 9:16 | Stories and short-form video covers |
| Landscape | 16:9 | Video thumbnails and link previews |
| Wide banner | Varies | Channel headers, profile covers, website shares |
Platform specifications change, so confirm the destination's current requirements for paid campaigns or scheduled publishing. These ratios are a planning framework that helps one source image survive several layouts.
Design for the crop
Keep the subject, logo, and essential text inside a central safe area. A platform may crop the top and bottom of a portrait image or display only a square preview in a grid. Important details placed at the edge are the first things to disappear.
If a landscape photo must become a portrait post, do not simply squeeze it. Crop around the main subject, extend the background when appropriate, or create a designed frame that makes the unused space intentional. Check faces, product edges, and text after every crop.
Batch-create without losing the original
Use one high-quality source image as the master. Generate the square, portrait, vertical, and landscape variants from that master, not from a previously compressed social export. Give each output a clear filename such as campaign-product-4x5.jpg so the destination is obvious during publishing.
After creating the variants, compress the images for web delivery. JPEG is often practical for photographs, PNG is useful for sharp graphics or transparency, and WebP can reduce weight when the platform supports it. Open each export at its final display size before scheduling it.
Common social image mistakes
- Stretching a source into a new ratio instead of cropping or adding a background.
- Putting the headline where platform controls or profile overlays cover it.
- Using a tiny logo that disappears on a phone.
- Exporting every version at the maximum possible resolution and creating unnecessary file weight.
- Reusing one crop for every platform when each layout has a different focal point.
A small set of intentional variants usually performs better than one compromised image copied everywhere. Build the master once, then adapt the composition to the context.
