A correct canvas size does not guarantee a useful ad. A square image can become a vertical asset while its product, promise and call to action remain badly positioned. This guide starts with a reference creative and separates a technical size change from the harder question of whether the composition still communicates the offer.

How to run the investigation
Identify the fixed elements
List the product, logo, exact offer, mandatory disclosures and language that must survive. Use the original asset if possible rather than a compressed screenshot. Check that you have permission to reuse product photography, people and third-party marks.
Preview the destination placement
Inspect the actual placement preview and current platform guidance. Interface overlays vary, so do not treat a generic template as a permanent guarantee. Use the free safe-zone checker for a preliminary layout review, then verify the final asset in Ads Manager.
Choose the adaptation level
Crop when the focal subject and required information remain legible. Rebuild the layout when text or product placement cannot survive the new proportions. Develop a new concept when the reference depends on a format or behavior that does not translate.
Review the final communication
Read the creative at phone size, verify offer accuracy and check the destination. Compare the export with the reference. A generated layout may alter packaging, spelling or small text; those are review failures even when the composition looks attractive.
Decision worksheet
Use these rows to turn the investigation into an action. Add the actual account, date range, evidence and owner before sharing it with a client.
| What you find | Interpretation | Next move |
|---|---|---|
| Product and offer remain clear after crop | Simple adaptation may suffice | Check the actual placement preview. |
| Text collides with controls | Composition needs rebuilding | Reposition information rather than shrinking everything. |
| Original relies on dense comparison text | Format may not carry the concept | Create a simpler vertical story. |

Worked example: an illustration, not a customer result
Imagine a square skincare ad with the bottle centered and the offer along its bottom edge. A centered vertical crop preserves the bottle but leaves the offer behind an interface control. The right repair may be a rebuilt hierarchy, not a smaller bottle or a claim that the file is safe because its dimensions are correct.

A question worth asking
Does the safe-zone checker certify Meta approval?
No. It is a layout aid, not policy approval or a substitute for a real placement preview. Check the current platform requirements and the finished asset before launch.
