# Check your photo against Google Shopping's rules.

Google Shopping sets rules for the main image that can be measured from the photo: product fill. Drop a photo to see which ones it meets. It runs in your browser; nothing is uploaded.

## Choose a marketplace and a photo.

Rules come from each marketplace's own help pages, summarised in the [guides](https://herofab.app/guides/) (checked 24 September 2026). Size, file size and format are checked as well.

## What Google Shopping asks for.

## How each rule is measured.

- **Product fill:** The product is separated from a plain background by growing the background inwards from the edges until the colour changes sharply. Fill is the product's share of the frame on its longest axis, the way Amazon's 85% and Google's 75–90% rules are read.
- **Scene photos:** Room and lifestyle photos have no plain background to measure against, so fill, edges and shadow are marked as not measured rather than guessed.
