Portrait vs square
A 4:5 feed creative usually earns more screen space than a square image, while 1:1 can be useful when the same asset must travel across multiple channels. Previewing both makes the trade-off visible.
Feed ad review points
Feed is less sensitive to vertical safe zones than Stories or Reels, but it is still easy to lose impact through weak crop, tiny product details or copy that does not connect to the CTA.
- Check that the product or offer remains clear in the crop.
- Keep the first caption line specific and useful.
- Make sure brand name, visual and destination all match.
- Avoid adding too much small text inside the creative.
Use Feed previews for approval
A feed mockup is often the easiest preview to share with clients because it resembles the context where the ad will be judged: a fast scroll with competing posts around it.
