Build and preview Facebook ad creatives for feed, stories, reels, and right column placements. Check image ratios and text overlay limits.
The Facebook Ad Preview Builder places a proposed Facebook creative into four named contexts: feed, Stories, Reels, and right column. Supply the image and ad text, then inspect the placement views while checking the image ratio and the amount of text over the image. This is a preflight view for deciding whether one asset can be reused or needs a placement-specific version. The common mistake is treating a tidy preview as proof of approval or exact delivery. It does not represent Meta's policy review, auction, targeting, or every device-dependent rendering.
Begin with the exact image and wording intended for the ad. The builder arranges those creative elements as a Facebook ad mockup rather than creating a campaign. Keep the inputs unchanged while comparing feed, Stories, Reels, and right column. That makes differences in cropping, available space, and text wrapping easier to attribute to the placement instead of to a different asset.
The image-ratio check helps identify a mismatch between the asset's proportions and the selected placement. Use the text-overlay check for wording placed over the image, which is distinct from ordinary ad copy shown around the creative. A warning can prompt a new crop, a placement-specific asset, or less embedded wording. These checks do not determine whether the message itself complies with advertising policy.
No. This tool is for composing and previewing creative in the browser. It does not upload the asset to Facebook, create an ad, select an audience, set a budget, or start delivery. Transfer the chosen image and copy into the campaign workflow separately. Because no campaign is created, the preview cannot provide an account-specific review or delivery result.
No. A passing check means only that the current creative did not trigger the builder's image-ratio or text-overlay concern for the previewed placement. Ads Manager may show different device variants, crops, controls, or line breaks, and Meta performs its own policy review. Verify the final placement previews in the campaign interface and consult Meta's current creative guidance and advertising standards before launch.
