Google Ads Image Sizes: Complete Guide for 2025
Google Display Network reaches 90% of internet users. Getting your image specs right means more placements, better quality scores, and lower CPMs.
Google Ads serves images across the Display Network, YouTube, Gmail, and Discover — each with different size requirements. Unlike Meta which focuses on a handful of aspect ratios, Google has historically required specific pixel dimensions for Display ads.
With Performance Max and Responsive Display Ads, Google now accepts just a few core ratios and generates variants automatically. But you still need to provide images at the right sizes to unlock all placements.
Quick Reference: Google Ads Image Sizes
Important: For Responsive Display Ads and Performance Max, Google requires at least one landscape (1.91:1) and one square (1:1) image. Without both, some placements won't be eligible.
Responsive Display Ads (RDA)
Responsive Display Ads are Google's standard format. You provide images, headlines, and descriptions — Google assembles them into ads that fit any available placement. You can upload up to 15 images per ad.
Google recommends keeping text to under 20% of the image area. Heavy text in images is one of the most common reasons Google gives images a low quality score.
Performance Max Campaigns
Performance Max (PMax) replaced Smart Shopping and runs across all Google channels: Search, Display, YouTube, Gmail, Maps, and Discover. It's the most important campaign type to get right in 2025.
For PMax, provide all 3 image ratios plus both logo formats. More asset variety = more placement options = better campaign performance. Google's machine learning optimises which combinations perform best over time.
Standard Display Ad Sizes (Fixed)
If you're running traditional Display ads (not Responsive), these are the sizes that reach the most inventory on the Google Display Network:
For most advertisers today, Responsive Display Ads are the better choice — they reach more placements with less production effort. Only use fixed-size display ads if you have specific design requirements that Google's assembly can't achieve.
Google's 150KB Recommended File Size
While Google allows up to 5MB, they recommend keeping images under 150KB for faster loading. Page speed affects Quality Score, which affects CPC.
A 1200×1200 JPG at 90% quality typically comes out at 300-500KB. To hit 150KB you need to compress to around 70-75% quality — which is usually still visually clean for advertising purposes.
MetaClean compresses to Google's recommended limits automatically when you select the Google platform — landscape, square, and portrait formats in one download.

What is the most important Google Ads image size?
1200×628px (1.91:1 landscape) is required for most placements and should be your first priority. Pair it with 1200×1200px (1:1 square) to unlock the full Display Network and Performance Max placements.
What file format should I use for Google Display ads?
JPG for photos and complex images (smaller file size). PNG for graphics, logos, or images with text (lossless, supports transparency). Avoid GIF unless you specifically need animation.
How many images should I upload to Performance Max?
Upload the maximum allowed: up to 20 images across all ratios. More assets give Google's machine learning more combinations to test, which typically improves performance over time. Always include at least landscape, square, and portrait.
Why does Google reject my Display ad images?
Common rejection reasons: images with more than 20% text overlay, blurry or low-resolution images, images with borders that take up more than 20% of the image area, and images that don't meet minimum size requirements.
Does image metadata affect Google Ads?
Metadata doesn't directly affect Google's ad approval, but it does affect file size. Stripping EXIF data can reduce a JPG by 10-50KB — meaningful when targeting the 150KB recommended limit. It also protects location privacy.
