FAQ
Are these the official IAB standard ad sizes?
The display-ad entries reflect the sizes most widely used across ad networks (based on IAB standard ad unit guidelines), while the social-media entries reflect each platform's current recommended image dimensions. Always double-check against the specific ad network or platform you're publishing to, since guidelines change over time.
Why do some banner sizes look identical to social media image sizes?
A handful of dimensions, like square formats, are reused across both display advertising and social platforms because they work well in many types of feeds and placements.
Can I search or filter this list?
Yes — use the category dropdown to narrow to Display, Mobile, or Social sizes, or type in the search box to filter by banner name.
Do these dimensions guarantee my ad will be accepted?
Not on their own. Ad networks and platforms often have additional requirements around file size, format, and aspect ratio beyond just pixel dimensions — treat this as a starting reference, not a full compliance checklist.
