Frequently asked questions

Which platforms are covered?

Google Ads, Meta, LinkedIn, TikTok and programmatic display formats.

What are the Meta ad sizes?

Meta formats vary by placement, such as feed, stories and reels. Open the Meta section in the directory to see each placement.

Are these specs guaranteed?

They are planning references. Platforms update requirements, so check the platform's own documentation before final delivery.

Why does my creative get rejected?

Common causes are the wrong aspect ratio, an oversized file or copy over the character limit. Check each against the listed spec.

Where do I find specs for outdoor and print?

Use the Australian OOH and traditional media directory, which covers outdoor, print, radio, TV and cinema.
