- Responsive display ads combine your images, logos, headlines, and descriptions automatically across placements.
- Upload landscape (1.91:1), square (1:1), and vertical (9:16) images to maximize placement coverage.
- Headlines cap at 30 characters. Descriptions cap at 90 characters. Keep each asset self-contained.
- Never overlay text, logos, or buttons on ad images. Google prohibits it and it hurts small-screen readability.
- Upload 3-4 ad variations per ad group and let data decide which message wins.
- Coinis generates and resizes ad creatives to Google's exact specs before you upload to Ads Manager.
What Are Google Ad Design Templates?
Google doesn't use design templates the way print tools do. It uses an asset-based system. You supply images, logos, headlines, and descriptions. Google's machine learning assembles the ad.
The asset-based design approach
Each responsive display ad draws from a pool of assets you upload. Google handles composition, sizing, and placement. One set of assets runs across thousands of publisher sites and apps in the Google Display Network.
How responsive display ads use machine learning
Per Google's Ads Help Center, Google tests combinations of your assets and prioritizes mixes that drive results. More assets give the algorithm more to work with. Up to 15 images and 5 short headlines create a large combination space for Google to optimize.
Template vs. custom design workflows
A template approach means uploading well-composed assets into Google Ads and letting the platform combine them. A custom approach uses uploaded display ads, static files designed to fixed IAB sizes. Most advertisers start with responsive display ads. They cover more placements with less design effort.

Image Specifications & Dimensions
Correctly sized images are the foundation of every Google display ad. Per Google's Ads Help Center, responsive display ads support three aspect ratios.
Landscape/horizontal images (1.91:1 aspect ratio)
Minimum resolution is 600 x 314 px. Recommended resolution is 1,200 x 628 px. Most high-traffic placements favor this ratio. Upload at the recommended size whenever possible.
Square images (1:1 aspect ratio)
Minimum resolution is 300 x 300 px. Recommended is 1,200 x 1,200 px. Square images cover placements where landscape doesn't fit. Uploading both ratios maximizes your reach.
Vertical/portrait images (9:16 aspect ratio)
Vertical images are optional but add mobile placements. Recommended resolution is 900 x 1,600 px. Minimum is 600 x 1,067 px. Use this format when your product looks strong in portrait orientation.
File sizes and upload requirements
Maximum file size per image is 5,120 KB (5 MB). Accepted formats are JPG and PNG. Google Ads accepts up to 15 images total across all three aspect ratios.
---
Logo & Brand Asset Guidelines
Logos appear alongside your images in many placements. Get them right once and every ad benefits.
Logo aspect ratios and sizing
Per Google's Ads Help Center, logos should use a 1:1 (square) or 4:1 (horizontal) aspect ratio. Both are recommended. The same 5 MB file size limit applies to logos.
Logo design best practices
Use a clean logo on a transparent or white background. Avoid busy crops. The logo must be recognizable at small sizes because some placements render it quite small.
How logos appear in ads
Google combines your logo with your image assets automatically. The placement determines size and position. You don't control the exact layout. That's why a clean, high-contrast logo matters more than a detailed one.
---
Text Asset Requirements
Headlines and descriptions are the copy layer of your ad. Write each asset to stand alone.
Headline character limits and formatting
Per Google's Ads Help Center, short headlines cap at 30 characters each. You can upload up to 5 short headlines for responsive display ads. A long headline allows up to 90 characters. Keep headlines specific. Vague headlines waste the character budget.
Description text limits and guidelines
Descriptions cap at 90 characters each. You can upload up to 5. Business name is limited to 25 characters. Google may show any description without the others, so write each one to be complete on its own.
When to overlay text vs. use clean images
Don't overlay text on your images. Google's guidelines prohibit it. Text overlays create visual clutter when combined with headline assets and become unreadable at smaller ad sizes. Naturally embedded text in a photograph is fine. Floating promotional text on a product photo is not.

Design Best Practices for Google Ads
Good asset design is specific and focused. Complexity is punished by placement variety.
Image quality and composition standards
Use high-resolution images. Focus on a single product or service. Natural lighting and organic shadows perform better than studio composites. Per Google's best practices guide, digital composite backgrounds are explicitly discouraged.
Avoiding common design mistakes
Common errors that hurt performance or trigger disapproval: collage images, text overlays, button overlays, blank space exceeding 20% of the frame, and promotional pricing embedded in the image itself.
Optimizing product/service focus
One product. One scene. One clear story. Ads that try to show everything convert less than ads that show one thing well. Tight composition with a visible subject outperforms wide, cluttered shots.
Backgrounds and shadows
Use physical settings and real shadows. Google's documentation discourages solid-color backgrounds and digital composites. A product on a real surface typically outperforms the same product on a pure white cutout.

How to Build & Test Multiple Designs
One set of assets is a start. Multiple sets are a testing strategy.
Creating 3-4 variations per ad group
Google recommends 3-4 ads per ad group. Each variation should use different images and different copy angles. Give the algorithm something to compare, not just more of the same.
Using A/B testing for performance
Different messages work for different audiences. One variation might emphasize price. Another might emphasize quality or urgency. Let data decide. Don't pick a winner before the test runs.
Leveraging AI asset enhancements
Google may apply AI asset enhancements to improve performance, including cropping, color adjustments, and format adaptation. Upload your best-quality assets and let Google optimize from there.

Frequently Asked Questions
What image sizes do I need for Google display ads?
For responsive display ads you need at least a landscape image (1.91:1, recommended 1,200 x 628 px) and a square image (1:1, recommended 1,200 x 1,200 px). A vertical image (9:16, recommended 900 x 1,600 px) is optional but adds mobile placements. Maximum file size is 5 MB per image in JPG or PNG format.
Can I put text on my Google ad images?
No. Google's guidelines prohibit overlaid text, logos, and buttons on ad images. Text overlays become unreadable on smaller placements and create clutter alongside your headline assets. Naturally embedded text in a photograph is acceptable, but floating promotional text on a product image is not.
How many assets should I upload for responsive display ads?
You can upload up to 15 images, 5 short headlines, 1 long headline, 5 descriptions, and logos in both 1:1 and 4:1 aspect ratios. More assets give Google's machine learning more combinations to test. Google recommends at least 3-4 ad variations per ad group.
Do I need all three image aspect ratios for responsive display ads?
Landscape (1.91:1) and square (1:1) are the most important. Vertical (9:16) is optional. Uploading all three gives Google the most placement options and maximizes your reach across the Display Network.
