Image Sizing | Product Feeds For Google, META, Bing, Criteo, AWIN, Marketplaces & More

Shopify Discussion

Topic summary

Best practices for managing product image aspect ratios across a Shopify+ site versus external channels. The new site (expansion stores) will use portrait images, while paid channels typically require square 1:1 images and marketplaces vary but are mostly portrait.

Context: Selling via Google Ads, Bing Ads, META, Bing, Criteo, AWIN, and marketplaces like Amazon Seller Central and Next. The poster wants to keep portrait images on the site/marketplaces and send controlled square images to paid channels.

Options under consideration:

  • Allow paid channels/marketplaces to auto-crop.
  • Use dedicated, channel-specific feeds/apps to crop/resize and sync per spec.
  • Manage master assets outside Shopify (e.g., ERP—Enterprise Resource Planning) and push channel-tailored variants.

Goal: Avoid uncontrolled platform auto-cropping, preserve composition/branding, and meet each platform’s requirements.

Request: Advice on real-world workflows, tools, and how others handle mixed ratio requirements.

Hi there,

I’m looking for some advice on how to manage image sizing on our website versus other eCommerce placements. Our new website, which will be on Shopify+ (expansion stores), will have portrait sizing. However, we also sell on the following paid channels: Google Ads, Bing Ads, META, Bing, Criteo, AWIN, and more. Additionally, we sell on marketplaces such as Amazon Seller Central, Next, and others. It’s recommended that paid channels use square 1:1 ratio images, while marketplaces require varying sizes, though mainly portrait.

My question is, how do others handle imagery sizing requirements for paid channels and marketplaces when the images on their site don’t follow the same ratio? Do they allow the paid channels and marketplaces to auto-crop the images, do they crop and sync via a dedicated feed/app per channel/marketplace, or use another method?

Ideally, I would like to see the Shopify site maintain the portrait sizing, which aligns with most marketplaces, while sending controlled square images to paid channels. I’m aware that some companies don’t use the images stored on their stores but manage them via ERPs, while others just enable auto-cropping. Your advice would be greatly appreciated.
