Ecommerce product image requirements
Amazon main images need a pure white background (RGB 255,255,255), the product filling at least 85% of the frame, at least 1,000 px on the longest side for zoom, and no text, logos or watermarks. Renders are acceptable as long as they represent the product accurately. Shopify sets no hard limits, which makes consistency your problem rather than the platform's.
Amazon main image rules
The main image is the one Amazon polices hardest, because it is what appears in search results.
- Background must be pure white — RGB 255,255,255
- Product must fill 85% or more of the frame
- At least 1,000 px on the longest side to enable zoom; 2,000 px or more is recommended
- No text, logos, watermarks, borders or inset images
- The product must be the actual product being sold, in the packaging it ships in
- No props, accessories or additional items that are not included in the purchase
Are CGI renders allowed?
Yes — with one condition that matters more than the technique. Amazon regulates accuracy, not how the pixels were produced: the image must be a true representation of the product's physical characteristics as sold. A photoreal render built from the actual CAD or packaging artwork satisfies that. What does not is imagery that flatters or misrepresents — a finish the product does not have, proportions that are not real, contents that are not in the box. Some categories are stricter about the main image than others, so if you are in a regulated category it is worth checking your category's own guidance before committing a full set.
Secondary images are where the selling happens
The main image gets the click; the rest get the purchase. Secondary slots are far less restricted, and they are where scale references, in-use and lifestyle scenes, detail crops, exploded views, dimension diagrams and comparison shots go. This is also where CGI has its largest advantage, because most of these images are difficult, expensive or impossible to photograph — a cutaway of a sealed product being the obvious example.
Shopify and your own store
Shopify imposes no equivalent rules, which sounds like freedom and behaves like a trap: with nothing enforcing consistency, most stores end up with a grid shot at different distances, on different whites, under different light. The fix is to set your own spec and hold it — one aspect ratio, one background value, one product-to-frame ratio, one lighting setup. This is another place rendering has a structural advantage, since consistency is a property of the setup rather than something a photographer has to reproduce months later.
A spec worth adopting
- Square 1:1 for listing grids, at 2,000 x 2,000 px or larger
- Pure white (255,255,255) for every listing image, no near-whites
- One fixed product-to-frame ratio across the whole catalogue
- sRGB colour space, and check it survives your CMS export
- JPEG for photographic content, PNG only where genuine transparency is needed
- A consistent naming convention that encodes SKU and shot type
- One master set at full resolution, with every downsize derived from it
Questions
What size should Amazon product images be?
At least 1,000 px on the longest side to enable zoom, with 2,000 px or more recommended. Zoom measurably affects conversion, so sitting at the minimum is a false economy.
Does the background have to be pure white?
For the Amazon main image, yes — RGB 255,255,255 exactly. A near-white will read as grey against the page and can fail review. Secondary images are not held to this.
Can I use a 3D render as my main Amazon image?
Yes, provided it accurately represents the product as sold. The rule is about accuracy rather than technique. A render built from the real CAD or packaging artwork meets it; one that shows a finish or proportion the product does not have does not.
How much of the frame should the product fill?
85% or more for Amazon main images. Products floating in white space with large margins are one of the most common reasons a listing image looks weak next to competitors in the search grid.
How many images should a listing have?
Use every slot the category offers. The main image earns the click, and the secondary images — scale, in-use, detail, dimensions, what is in the box — are what answer the objections that otherwise end the visit.
