"Image too small" in Google Merchant Center means the main image on a product is below Google's minimum pixel size. The minimum is going up, so this issue is appearing on products that used to pass. Here is what the rule is, how to find the affected products, and how to fix them.
What the size rule is
Google's help page for this issue lists two minimums that apply until January 31, 2027, and a single higher minimum that is enforced from that date. Warnings for images under the new minimum started in July 2026.
| Rule | Minimum size |
|---|---|
| Non-clothing products, until January 31, 2027 | 100 x 100 pixels |
| Clothing products, until January 31, 2027 | 250 x 250 pixels |
| All products, enforced from January 31, 2027 | 500 x 500 pixels |
Google recommends going well beyond the minimum, to around 1500 x 1500 pixels or above. Images also cannot be larger than 64 megapixels or 16MB.
Warning or disapproval
Google says products without an image of the right dimensions are disapproved, which means they cannot appear in ads or free listings. An image that meets the old minimum but is under 500 x 500 gets a warning for now.
- Below the current minimum: The product is disapproved
- Between the current minimum and 500 x 500: A warning, until enforcement begins
- Warning name to look for: "Image too small for upcoming enforcement"
Find the affected products
In Merchant Center, go to Products and open the Needs attention tab. Use the filter to show products with this issue. For a long list, use the download icon to get a .csv of affected products.
- One product: Select the product title, then Edit product
- Many products: Download the list and match it to your product data
- Upcoming enforcement: Under Needs attention, select View history to find the warning
Replace the image, do not stretch it
The fix is a new, larger image. Google's guidance is to avoid thumbnails and images that have been scaled up, so enlarging the small file in an editor is not the answer. Go back to the original photo or reshoot.
- Source file: Export from the original photo at 1500 x 1500 or above if you can
- Framing: Google suggests the product fills about 75% to 90% of the image
- Format: JPEG and WebP are recommended, and PNG, GIF, BMP and TIFF are supported
- Shopify stores: Replace the product's image in Shopify so the new file is what your product data points to
Google also offers Product Studio in Merchant Center, which it says can increase image resolution.
After you upload
For a single product, replace the image in Edit product and save. For many, update the image link attribute in your product data and send it again. Google says changes may take 24 to 72 hours to show on the Needs attention page.
- Still flagged after 72 hours: Check that the image URL in your data points to the new file
- Other image issues: See fixing text on images
- Other disapprovals: See fixing disapproved products
