One last look.

Can you read the hook? See the product? Follow the CTA? Play the full clip and watch for anything that slips behind the interface.

Layouts are illustrative. Guides are estimates, not an approval check. Caption length, device and ad format can change what appears. Always check the platform's own preview before publishing.

Feed Check / Field notes

A quick check.
A clearer creative.

  1. Add a video or image. It stays in your browser. Closing or reloading the page clears it.
  2. Choose the placement. Switch between organic, paid partnership and ad layouts. Compare matching placements side by side.
  3. Check the full creative. Scrub through your video, preview the crop and toggle the interface. No automatic text detection is performed.
  4. Take it with you. Download a still mockup, or export a transparent guide for your editor. Links share the setup, never the media.

About the guides

For Meta vertical ad previews, the default guide leaves 14% clear at the top, 35% at the bottom and 6% on each side. Organic, feed and TikTok defaults are adjustable visual estimates. The dashed area is a composition aid, not a guarantee that every interface variant will leave it clear.

TikTok describes its safe zone as dependent on dimensions, caption length and additional formats. Use its official templates for a specific ad format. Interface labels, engagement counts and navigation shown here are illustrative.
