Google Merchant Center image requirements: prepare now for 500×500
Google began warning in July 2026 about product images below 500×500. The universal 500×500 minimum is enforced January 31, 2027; until then, the legacy minimum remains 100×100 for non-apparel and 250×250 for apparel.
Passing today’s minimum is not the same as preparing a durable feed. Google recommends images around 1500×1500 or larger for performance, caps files at 64 megapixels and 16MB, and recommends framing the product at roughly 75–90% of the image.
Upgrade a feed without waiting for disapprovals
Find the affected products
Open Products → Needs attention in Merchant Center. Use View history to inspect upcoming-enforcement warnings, then View fix → Download impacted products to work from the affected-item list.
Create a durable high-resolution master
Use a clean source around 1500×1500 or larger when possible. Keep the file at or below 64 megapixels and 16MB, and do not upscale a tiny thumbnail.
Frame the correct product
Aim for the product to occupy roughly 75–90% of the image. Show the exact item and variant, include all items in a declared bundle, and avoid unrelated props in the main image.
Publish a stable, crawlable image URL
Use a direct image URL that Google can fetch. Keep URLs stable while an image is unchanged; avoid rotating timestamps or session parameters on every feed submission. Check the image format and crawl access when replacing the asset.
Preserve AI provenance and validate
For generative-AI images, preserve supported IPTC digital-source metadata. Test representative URLs, resubmit the feed, and monitor Diagnostics until the new image is processed.
The 2026 warning and 2027 enforcement timeline
Editorial and verification method
We rechecked Google’s image-link specification and image-too-small troubleshooting page on October 10, 2026. The specification leads with 500×500 while troubleshooting explains the transition deadline. We distinguish those rules, use the current Needs attention workflow, and retain stable-image-URL guidance.

Google says enforcement of the universal minimum of 500×500 begins January 31, 2027.
What image size does Google recommend for best performance?
Google recommends images around 1500×1500 pixels or above when possible. Files cannot exceed 64 megapixels or 16MB.
Can I use generative-AI product images in Merchant Center?
Google’s image-link guidance says generative-AI images must retain metadata indicating their digital source, such as supported IPTC DigitalSourceType values. The image must still accurately represent the product and comply with all other rules.
