|---|---|---|---|
| Landscape image | 1200×628 (1.91:1) | 600×314 | Maximum upload size is 5120 KB for responsive display image assets. |
| Square image | 1200×1200 (1:1) | 300×300 | Use a single clear subject and avoid text that becomes unreadable when resized. |
| Vertical image | 900×1600 (9:16) | 600×1067 | Useful for eligible vertical inventory; treat it as a separate composition. |
| Logo | 1200×300 (4:1) or 1200×1200 | 512×128 landscape or 128×128 square | Upload a clean logo asset with enough padding for responsive layouts. |
| Uploaded display units | 300×250, 336×280, 728×90, 300×600 | Depends on the unit | Use responsive assets when you want Google to assemble more layouts; uploaded units are a separate format. |
How to prepare the creative
- Prepare at least one landscape and one square asset; add vertical assets when the campaign can use them.
- Keep the image focused on the product or service and do not use a graphic button that implies a false UI control.
- Preview headlines, descriptions and images together because responsive combinations can change the visual hierarchy.
