Ad specs / Google
Google responsive display ad size
A Google responsive display ad needs a 1.91:1 image at 1200 × 628 pixels (600 × 314 minimum) and a square one: 600 × 600 on Google's responsive display ads specs page, 1200 × 1200 in its best practices guide, 300 × 300 minimum on both. Google assembles each ad from those images and up to five 30-character headlines, a 90-character long headline and up to five 90-character descriptions. Google is moving Display campaigns into Demand Gen, starting with a migration tool in June 2026.

| Demand Gen | Google's Display to Demand Gen page: from June 2026 a migration tool, rolled out in phases, moves eligible Google Display Ads campaigns to the Google Display Network on Demand Gen, where responsive display ads are supported; later, new Display campaigns can only be created within Demand Gen and the remaining eligible ones move automatically |
