A Facebook AI ads generator built for the feed’s shapes
Meta’s feed rewards 4:5 and 1:1 with a face that survives a small preview. Render creatives composed for those shapes, with room left where the headline and button will sit.
Make a feed creative
Step one renders the feed-shaped still, and step two plays a motion preview of that image.
Describe your product in the prompt — colour, packaging, label — and your AI actor will hold it.
Feed creative has its own constraints
Facebook and Instagram feeds are not TikTok. The unit is taller than it is wide but not full-screen, a headline and description sit underneath, and a call-to-action button crops into the layout. A creative composed for a 16:9 landing page hero loses its subject entirely in that context. A facebook ai ads generator that renders natively at 4:5 and 1:1 solves this at the source: the presenter is framed for the shape the ad actually occupies, so the face lands where the eye goes rather than where the crop left it.
There is also the small-preview problem. Feed creatives are frequently seen at a fraction of their exported size, often while the viewer is scrolling with one thumb. Detail disappears; silhouette, contrast and where the face is pointing are what remain. Composing for those three things is most of the job, and it is a prompt-level decision rather than a post-production one.
Feed-native advantages
4:5 and 1:1 without cropping
Render directly into the shapes the placement uses. No re-cropping a horizontal master, no discovering that the product ended up outside the frame in the tallest variant, no headline overlapping a face that was never positioned for it.
Composed for the headline block
Keep the subject high and leave the lower area uncluttered so the headline, description and button do not fight the image. Describing the framing this way in the prompt is far more reliable than trying to fix it afterwards.
Faces that read at preview size
Strong contrast, a clear silhouette and an unambiguous expression survive being shown small. Fine detail does not. Write for the version the audience sees, not for the version sitting in your asset folder at full resolution.
Producing a feed set
Composed for 4:5, checked at preview size, iterated on the face.
Write for a small preview
Describe a clear subject with strong separation from the background and an expression readable at a glance. Busy scenes that reward inspection are the wrong choice for a placement nobody inspects.
Render 4:5 first, then 1:1
Generate the taller shape first since it takes the most feed real estate, then re-render the same concept square. Two native renders beat one master image cropped two ways every time.
Preview motion and refine expression
Play the motion preview to check the presenter looks approachable rather than staged, then adjust the expression and wardrobe wording. Expression is usually the highest-leverage variable in feed creative.
Meta placement questions
4:5 for the feed, because it claims the most vertical space without being cropped, and 1:1 as a safe alternative that behaves predictably across placements. Render each natively rather than exporting one image and cropping, or the subject position drifts between the two.
Keep the creative clean and put your message in the headline and primary text fields. Baked-in text cannot be tested or localised without regenerating the image, and it competes with the platform’s own typography sitting directly beneath it.
Direct eye contact tends to perform well in the feed because it reads as address rather than observation. Product-focused gaze works when the demonstration is the point. Both are a single word in the prompt, so run them against each other.
Four to six genuinely different creatives is a sensible starting set — different presenters, different settings, different gestures. Twenty near-identical variants split your budget across noise and rarely produce a readable result.
