Working sizes
| Asset | Dimensions | Aspect ratio | Media type |
|---|---|---|---|
| Product square | 1200 × 1200 px | 1 / 1 | Image |
| Store banner | 1200 × 400 px | 3 / 1 | Image |
Why these numbers matter
Marketplaces, social networks, and streaming services resize, crop, or reject media that misses their working size. Building each asset inside the published size keeps the product, title, and artwork in frame instead of being re-cropped after upload.
