What Size should images be for Google Ads?

Why Brands Need the Right Image Assets Before Advertising on Google.

One of the most common challenges brands face when starting with Google advertising, especially those transitioning from platforms like Amazon to direct-to-consumer, is a lack of ready image assets. Many brands launch Performance Max or Display campaigns with enthusiasm, only to see their results plateau after a few days or weeks. Why does this happen? The answer is often straightforward: insufficient high-quality images in the correct sizes.

Why Image Assets Matter

When you start advertising on Google, your campaigns rely heavily on visuals to attract and convert customers. If you use only a few images, rely on generic stock photos, or skip strong calls to action, your campaign’s performance will drop over time. Google’s AI and algorithms need a variety of images to test and optimize what works best for your audience.

We often hear from clients:

• “What size images do I need?”
• “How many images should I prepare?”
• “Why aren’t my ads getting traction?”

The answer is: before you spend money on ads, make sure you have a complete set of image assets ready. This preparation will save you time, money, and frustration down the road.

Google Display & Performance Max: Required Banner Sizes

Here are the standard image sizes you should prepare for Google Display and Performance Max campaigns:

Google Display Ads – Required Banner Sizes

• Landscape & Square
  • 1200 × 1200 px
  • 1200 × 628 px
  • 1080 × 1080 px
  • 1200 × 300 px
  • 300 × 250 px
  • 336 × 280 px
  • 728 × 90 px
  • 160 × 600 px
  • 300 × 600 px
  • 970 × 250 px

Performance Max Campaign – Required Image Sizes

• Square Images
  • 1200 × 1200 px
  • 1080 × 1080 px
• Landscape Images
  • 1200 × 628 px
  • 1000 × 300 px
• Portrait Images
  • 960 × 1200 px
  • 480 × 600 px

Tip: Provide all banners in PNG format, maintain consistent branding, and ensure your product is clearly visible.

How Many Images Do You Need?

For best results, aim for at least 10–20 creatives per campaign. For Performance Max, aim to have at least 12 images per shape (square, landscape, portrait). This gives Google’s AI enough options to optimize your ads and find what works.

Refresh Your Assets Regularly

Update your images every 30 days to keep your campaigns fresh and maintain traction. Stale photos can lead to ad fatigue and lower performance.

Make Your Images Work Harder

Don’t just use product shots or logos. Add strong calls to action and value statements directly on your images.

For example, if you’re selling hand soap, show someone using the product and include a phrase like “Organic Soap” or “All Natural” on the image. This helps your ad stand out and increases your click-through rate.

Final Thoughts

Having the right image assets is essential to success in Google advertising. Prepare your images in advance, use the correct sizes, and update them regularly. This will help you avoid common pitfalls and get the most out of your ad spend.
