Producing high-performing Demand Gen image assets requires mastering the exact specs for landscape, square, and portrait ads. Google’s Demand Gen requirements focus on three standardized aspect ratios: landscape 1.91:1, square 1:1, and portrait 4:5. To consistently achieve maximum placement coverage, create images at recommended resolutions, observe strict file size limits, and safeguard key creative elements within safe zones for every format.
Getting image specs right in the first steps of production directly impacts campaign reach and creative quality across Google and paid social placements. A single misstep—such as uploading just one ratio or exceeding the 5 MB file limit—can dramatically limit inventory, degrade the visual experience, or force time-consuming revisions for your design team. By standardizing export sizes and adopting efficient, repeatable workflows, agencies and marketers reduce friction between creative and media operations.
Definition: What Are Demand Gen Image Specs?
Demand Gen image specs refer to the technical and dimensional requirements for creative images in Google Demand Gen campaigns and similar cross-channel ad placements. These specs include precise aspect ratios (landscape, square, portrait), recommended pixel dimensions, accepted file types (JPG, PNG), and maximum file size limits. Following these standards ensures assets are eligible for all intended inventory and display correctly across mobile and desktop environments.
Core Demand Gen Image Sizes
| Format | Aspect Ratio | Minimum Size (px) | Recommended Size (px) | Max File Size |
|---|---|---|---|---|
| Landscape | 1.91:1 | 600 x 314 | 1200 x 628 | 5 MB |
| Square | 1:1 | 300 x 300 | 1200 x 1200 | 5 MB |
| Portrait | 4:5 | 480 x 600 | 960 x 1200 | 5 MB |
Google supports JPG and PNG files for all three formats, with static GIF allowed in some cases. To avoid delivery issues, never upload files above 5 MB. More details are available in Google’s official help documentation and leading industry guides, but always double-check for any network-specific updates before launch.
Why Exact Specs Matter in Production
Demand Gen formats don’t just dictate where your ads will serve—they influence how well your message is seen and whether campaign assets get full reach across all possible placements. Designing solely for landscape or using incorrect resolution leads to poor mobile rendering, logo cropping, or headline truncation, especially in square and portrait placements. For agencies handling high campaign volumes, ignoring spec standards creates costly feedback loops and extends creative timelines. That’s where workflow-optimized tools such as SizeIM become mission-critical, automating multi-size exports so designers focus on creative rather than manually redrawing for each placement.
Step-by-Step Framework for Efficient Ad Production
- Start by designing your master concept at the highest recommended size and resolution (for example, 1200 x 628 for landscape).
- Set up separate artboards for all three required formats: landscape, square, and portrait. This allows for precise positioning and safe zone adherence.
- Keep all key content within safe zones (e.g., logos, headlines, and CTAs should never touch the crop edge).
- Export each variation as a JPG or PNG file under 5 MB, checking mobile and desktop readability.
- Test every ratio in preview tools or live campaigns to validate cropping, legibility, and branding consistency.
Landscape, Square, and Portrait Explained
Landscape (1.91:1)
- Versatile, suitable for hero banners, product launches, and lead offers.
- Recommended: 1200 x 628 px.
- Minimum: 600 x 314 px.
- Keep layout streamlined and place offers or logos away from edges to prevent accidental cropping on different feeds.
Square (1:1)
- Standard for social feeds, product ads, and brand storytelling.
- Recommended: 1200 x 1200 px.
- Minimum: 300 x 300 px.
- Centralize imagery and text for maximum visibility and balance, since tight cropping is more likely in square environments.
Portrait (4:5)
- Optimal for mobile-first experiences, vertical video teasers, and lifestyle visuals.
- Recommended: 960 x 1200 px.
- Minimum: 480 x 600 px.
- Use a clear vertical flow—headlines at the top, image focus in the middle, CTA at the base. Ensure all text remains readable on small displays.
Best Practices for Scaling Multi-Size Creative Production
- Design three core concepts for every campaign: pain point, product benefit, and offer angle.
- Export each core concept in all three formats for a total of 9 assets per campaign theme. This enables robust A/B testing and ensures every angle is represented across available inventory.
- Standardize layer structure in design files to facilitate faster resizing and QA checks.
- Centralize brand assets (like brand kits in SizeIM) to maintain logo, color, and font consistency, minimizing mistakes during rapid production sprints. For further guidance, see Using Brand Kits to Streamline Multi-Size Display Ad Production.
- Always validate files for file size and clarity on both mobile and desktop.
- Maintain a single editable master file (with artboards for all three aspect ratios) to quickly implement future updates without rework.
Common Mistakes to Avoid
- Uploading only one aspect ratio (limits campaign reach and results).
- Exceeding the 5 MB file size per image (prevents ad delivery in most networks).
- Packing too much text into imagery (damages mobile readability).
- Overlooking safe zones (results in logos or CTAs getting cut off).
- Using inconsistent brand elements (introduces quality control problems).
- Scaling up from low-resolution assets (degrades image sharpness and clarity).

FAQ: Demand Gen Image Specs & Ad Production
What are the required Demand Gen image ratios and sizes?
Google Demand Gen standardizes assets at landscape (1.91:1, 1200 x 628 px), square (1:1, 1200 x 1200 px), and portrait (4:5, 960 x 1200 px). Minimum sizes are 600×314, 300×300, and 480×600 pixels respectively. Each image file must be under 5 MB.
Why do I need all three aspect ratios?
Uploading all three ensures your campaign gets maximum inventory and visual quality across devices. If you skip square or portrait, your ads won’t be eligible for key feed and mobile placements.
How many versions of each image should I create?
For robust placement coverage and messaging variety, create three variations for each ratio (landscape, square, portrait), totaling nine assets per theme. This supports A/B testing of different creative concepts.
Can I automate resizing for Demand Gen images?
Yes. Solutions like SizeIM allow you to design once and generate all aspect ratios instantly, eliminating manual resizing work and enabling teams to handle large campaign volumes efficiently.
What’s the best workflow for multi-size asset production?
Standardize a master design file, use separate artboards for each required ratio, apply safe zones, export all images under 5 MB, and validate mobile legibility before uploading. Platforms like SizeIM streamline this process with automated templates and responsive design tools.
