Image Too Small in Google Merchant Center: The New 500 × 500 Minimum Before 31 January 2027

A warning you haven’t seen before is sitting in Merchant Center, or a product was rejected for an image that looks fine on your store. Google is raising the bar for every product photo: We will begin issuing warnings in Merchant Center starting April 14, 2026 for images which do not meet the updated minimum resolution requirement, with enforcement starting on January 31, 2027. The new minimum is 500 × 500 pixels, and “Image too small” in Google Merchant Center is the issue you’ll see if a product image misses it (Google’s announcement: Merchant Center product data specification update 2026).

You have until 31 January 2027. That is enough time to fix this calmly, one batch of products at a time. Google only shows a product when its image meets the rules.

What is the new image size rule?

Google’s announcement says it is increasing the minimum resolution for images submitted in the image link [image_link] and additional image link [additional_image_link] attributes to 500x500 pixels across all product categories and marketing methods.

In plain English:

• Every product, every category. From 31 January 2027, clothing no longer has a lower minimum.
• Main image and extra images. image_link is the main photo. additional_image_link holds the other angles and close-ups. Both are named.
• Shopping ads and free listings alike. “All marketing methods” is Google’s phrase.

Google’s image page carries the same date and adds a recommendation: When possible, we recommend that you provide images around 1500x1500 pixels or above to ensure best performance in all listing formats. (Google: Image link [image_link]). So 500 × 500 is the floor, not the target.

What is the minimum image size until then?

Until 31 January 2027 the older minimums still apply, and they do split by category: at least 100 × 100 pixels for most products and at least 250 × 250 pixels for clothing (Google says “apparel”). Google’s page on product data quality issues lists both under “Image too small” (Google: Fixing Merchant Center disapprovals for product data quality violations). A product that is disapproved for “Image too small” today missed one of those older minimums. A product whose image sits between those minimums and 500 × 500 gets a warning, not a disapproval, until enforcement starts.

Where does Google Merchant Center show “Image too small”?

Google tells you where to look: To see products impacted by this change, navigate to the Needs attention section of your Merchant Center account and click View history. The warning on the side of that page is called “Image too small for upcoming enforcement”.

1. In Merchant Center, open Products, then the Needs attention tab.
2. Click View history.
3. Look for “Image too small for upcoming enforcement” and note how many products it lists.
4. Download the list of affected products if your account offers it, so you can work through it in a spreadsheet.

A warning doesn’t stop a product from showing today. It tells you which products will have a problem after 31 January 2027 if nothing changes.

Will Google fix small images itself?

Sometimes. Google says We will also begin optimizing some images that are smaller than 500 x 500. and Importantly, these optimized images will meet the new image requirements and will prevent product disapproval without any action from you. Optimized images are marked with their own warning in Needs attention.

What Google doesn’t say: which images it will optimize, how it does it, or what happens to the small images it doesn’t optimize. Our reading: plan as if any main image under 500 × 500 can be disapproved from 31 January 2027, and treat Google’s optimization as a safety net, not the fix. If you want to replace an optimized image, Google’s answer is simple: To update an image that has been optimized, you can submit a new image that is larger than 500 x 500 in your product data source.

How do I find small product images on my store?

Merchant Center’s list is the one that counts, because it shows the image Google actually received. Your store can hold a large original while your feed sends a smaller copy. Check both sides.

On Shopify

1. Go to Products → Export and export all products as a CSV.
2. The Image Src column holds each image’s address, and Image Position 1 is the main image. Variant Image holds the image for each variant.
3. Open an image address in your browser to see the file Shopify stores. Shopify serves resized copies to your theme, but the address in the export is the uploaded file.
4. Compare the products in Merchant Center’s list with what you find. If the original in Shopify is large but Merchant Center still reports a small image, the problem is in what the sync or feed app sends, not in your photo.

Shopify’s own advice is well above Google’s minimum: For square product images, a size of 2048 x 2048 px usually displays best. (Shopify Help Center: Product media types).

On WooCommerce

1. Go to Media → Library, switch to the list view and click an image. The Attachment details panel shows its dimensions.
2. For the whole catalogue, use Products → Export. The Images column lists each product’s image addresses; the first one is the main (featured) image, the rest are the gallery.
3. WordPress makes resized copies of every upload and names them with the size at the end, like -300x300.jpg. If your feed plugin sends one of those copies instead of the full-size file, Google receives a small image even though you uploaded a large one. Check the image address your feed sends.

On other platforms

Export your products, or open the feed file you send to Merchant Center (CSV, TSV or XML), and list the image_link and additional_image_link values. Open a sample in your browser to check the size. If your platform resizes images for its theme, make sure the feed points at the original.

How do I replace small images without breaking my feed?

1. Find a bigger original. Your own photo, the photographer’s file or the supplier’s full-size image. Don’t enlarge the small one: Google’s rule is Don’t scale up an image or submit a thumbnail. (Google: Product data specification). Stretching a small photo adds pixels, not detail.
2. Check the new photo against Google’s other image rules. No promotional text, watermarks or borders, and no placeholder. See promotional overlays on images. If your photos come from a supplier, our post on supplier-hosted images covers what to check.
3. Replace the image on the same product. Edit the existing product in your store; don’t delete it and create a new one. Our reading: a new product gets a new ID in your feed, and Merchant Center treats it as a new item with no history.
4. Keep the main image first. On Shopify, drag the new photo to the first position in the product’s media. On WooCommerce, set it as the Product image; gallery images become additional images.
5. Fix at the source, not only in Merchant Center. If your products come from an app, plugin or feed, an edit made directly in Merchant Center can be overwritten at the next sync, in our reading. Change the image in your store or in the feed.
6. Let the sync run, then check Needs attention again. The warning should drop off for the products you fixed. If it doesn’t, compare the image address in Merchant Center with the one in your store.

If an image is missing altogether rather than too small, see how to fix a missing product image.

Google also points to its own Product Studio, which it says can increase image resolution. Google doesn’t say how that fits with its “don’t scale up” rule. Our reading: a real, larger photo is the safer choice.

What about additional images?

The announcement names additional_image_link, so the 500 × 500 minimum covers your extra photos too. What happens to an undersized extra photo after 31 January 2027, Google’s announcement doesn’t say. Our reading: replace them along with the main images (see the update further down), because they come from the same photo shoot or supplier and usually share the same problem. Variant images count too: each variant’s photo is what shoppers see for that variant.

What we see in real cases

Paraphrased from merchants’ forum posts:

• A Shopify merchant found their products stuck in Merchant Center because the images Google received were far below the minimum, though the photos in the store were fine. The advice in the thread: check the originals in Shopify first, then override the image addresses with a supplemental feed or ask the feed app’s support why it sent small copies.
• A merchant getting ready to request a review cleaned up their product photos along with their contact details and policies. Images were one item on a long list.
• An app vendor claimed that product images without alt text are invisible to Google, and other members corrected the claim. Check what you read about images against Google’s own pages.
• As of this post, the merchant threads we follow haven’t picked up the 500 × 500 rule yet. The warning is quiet, and it sits under View history, not on the main list.

Our reading: the image in your store and the image Google gets are not always the same file. Check what Merchant Center reports before you reshoot anything.

Update, 28 October 2026: Google’s fix page for the issue now gives a different start date for the warnings than the April announcement: Starting July 2026 you will see warnings on images larger than the minimum requirements but smaller than 500 x 500. The same page names a second warning to look for under View history, “Image resolution optimizations applied”, for images Google has optimized, and adds a way to download the affected products from View fix (Google: How to fix: Image too small). Google’s page on additional images now answers the question this post left open: If you include images that are under the minimum size requirements, your product won’t be disapproved, but your images won’t be shown. (Google: Additional image link [additional_image_link]). Since this post, the 500 × 500 rule has also reached the forums: an agency that measured one client’s catalogue found roughly one image in nine under 500 pixels, and a helper in the thread pointed out that Shopify never enlarges an image beyond the file you uploaded, so the original is what you need to measure.

FAQ

What does “Image too small for upcoming enforcement” mean?

It is Merchant Center’s warning for product images under 500 × 500 pixels. The product still shows today, but Google enforces the 500 × 500 minimum from 31 January 2027, so the image needs replacing before then.

Does the 500 × 500 rule apply to clothing and to all products?

Yes. Google says the new minimum applies “across all product categories and marketing methods”. The separate clothing minimum of 250 × 250 pixels only applies until 31 January 2027.

Can I just enlarge my existing images to 500 × 500?

No. Google’s product data specification says “Don’t scale up an image or submit a thumbnail.” Use a larger original photo instead.

Does the rule apply to additional images?

Yes. Google’s announcement names the additional image link attribute alongside the main image. Since this post, Google’s additional image page says an undersized extra image won’t get the product disapproved, but it won’t be shown, so replace them along with the main images.

What image size should I aim for?

At least 500 × 500 pixels, but Google recommends images around 1500 × 1500 pixels or above for best performance. Shopify suggests 2048 × 2048 pixels for square product images.
