Demand Gen image size requirements mandate the inclusion of at least one landscape image and one square image to ensure your ads function correctly across Google inventory. Google provides clear technical thresholds for these assets to maintain quality during automated delivery. Following these specific dimensions is necessary for the system to render your creative assets across various placements such as YouTube, Discover, and Gmail without distortion or cropping issues that might negatively affect your brand’s visual presence.
What are the core image specifications for Demand Gen?
When setting up your asset groups, the platform requires specific aspect ratios to fill available ad slots. For landscape imagery, the recommended dimension is 1200×628 pixels. This format is the standard for wide-screen displays across the Google network. If you fail to provide this, the system may struggle to find an appropriate slot for your ad, leading to reduced impression volume. Maintaining high resolution within these bounds is a standard best practice to prevent pixelation on modern screens.
The second essential requirement is the square image, with a recommended size of 1200×1200 pixels. Square assets are frequently used in mobile feeds and compact placement areas where a wider aspect ratio would not fit effectively. By uploading both a landscape and a square version, you provide the system with the flexibility to populate diverse ad slots automatically. This setup is the foundation of a properly configured Demand Gen campaign.
Why do aspect ratios matter for your campaign performance?
The visual delivery of an ad depends on the interface where it appears. A landscape ad might look perfect on a desktop browser but occupy too much vertical space on a phone. Conversely, a square asset fits neatly into vertical scroll feeds common in modern mobile applications. When you adhere to these size requirements, you allow the algorithm to match your visual assets to the user experience of the specific placement without forcing the image to scale or stretch in ways that degrade the visual message.
How should you prepare your creative assets?
Preparation starts with selecting high-quality source files that can be exported into these specific dimensions without losing clarity. Avoid adding excessive text overlays that might be cut off if the platform decides to crop the edges of your asset. Keep the primary focus of your image centered so that it remains visible even if minor adjustments occur during the rendering process. Using a consistent visual style across both landscape and square versions helps maintain brand recognition.
| Asset Type | Recommended Size | Primary Use |
|---|---|---|
| Landscape | 1200×628 | Desktop and wider placements |
| Square | 1200×1200 | Mobile feeds and compact slots |
| Portrait | Not required | Optional vertical placements |
Common technical mistakes to avoid in asset uploads
- Uploading files that are too small and result in blurry ads when scaled up by the browser.
- Including important brand elements or text too close to the edges of the image frame.
- Neglecting to provide both required formats, which limits your ad’s potential reach.
- Using images with low contrast that become unreadable when the system resizes them.
- Failing to check if your file size exceeds the platform’s storage limit for individual assets.
How Alien Road applies Demand Gen standards
At Alien Road, our team follows a structured process for every client account that utilizes Demand Gen. We begin by auditing the existing creative assets to ensure they meet the minimum 1200×628 and 1200×1200 requirements. If a client lacks these specific sizes, we guide them through the production phase to generate assets that align with Google’s technical specifications. We monitor the ad strength indicator within the Google Ads dashboard to confirm that the system recognizes the assets as high quality.
In a typical engagement, we also use the asset performance report to determine which images drive the highest engagement. By reviewing the performance metrics, we can swap out underperforming visuals for new ones that follow the same size guidelines. This iterative approach allows us to maintain a clean account structure while ensuring the ads remain competitive. We focus on clear, high-impact imagery that communicates the value proposition immediately upon impression.
Can you use images that exceed the minimum size requirements?
The platform accepts higher resolution images as long as they maintain the correct aspect ratio. While the recommended sizes are a baseline, using higher quality files can improve the appearance of your ad on high-definition displays. However, you must be careful not to exceed file size limits, as large files can cause delays in loading. Balancing high resolution with reasonable file compression is a key task for any marketing practitioner.
What is the best way to monitor your image performance?
- Check the Asset Details report in the Google Ads dashboard for individual image performance.
- Compare the CTR of landscape ads against square ads to see which format resonates more.
- Review the Ad Strength score provided by Google to identify if you need more variations.
- Look for rejected assets in the policy manager to address any potential quality violations.
- Use the preview tool to see how your assets appear across different Google placements.

Consistent auditing of your creative assets will help your campaigns reach their potential without technical interruptions.
Frequently Asked Questions
Do I need to upload portrait images for Demand Gen?
Portrait images are not strictly required for Demand Gen campaigns. The system mandates landscape and square formats as the primary assets. While you may have the option to upload additional sizes, focusing on the two required formats is sufficient for successful delivery across the network. Always verify that your landscape and square assets are high quality before adding extra variants.
What happens if my image size is incorrect?
If your image dimensions do not match the requirements, the platform will either reject the asset during the upload process or struggle to display it in certain placements. This often leads to a lower ad strength rating and reduced impressions. It is essential to export your files in the exact pixel dimensions specified to avoid these delivery issues and ensure your ads appear to your target audience.
How many images should I include per asset group?
While you must have at least one landscape and one square image, it is a common practice to include multiple variations. Adding a variety of images allows the system to rotate and test different visuals, which can help you identify what performs best for your specific audience. Aim for a mix of lifestyle and product-focused images to see which style drives better results.
Does file format affect my image performance?
Standard image formats like JPG or PNG are widely accepted and perform well. The most important factor is adhering to the pixel dimensions rather than the specific file type. Ensure your chosen format is optimized for web use to balance image quality with fast loading times. Avoid complex formats that might not be compatible with all Google placements or could cause rendering errors.
Can I use the same image for both landscape and square?
You can use the same base image, but you should crop it specifically for each format to ensure the subject remains visible. If you use a landscape image in a square slot without proper cropping, the system might cut off important parts of your creative. Take the time to create distinct versions that look natural in their respective aspect ratios to maintain a professional brand image.
