# ListingSpec

> Free, spec-correct templates for Amazon listing images and A+ content. Every dimension comes from Amazon's own published module guides, and each figure is marked with its source.

## Key facts

- Amazon publishes 19 Premium A+ modules and 14 Standard A+ modules.
- Premium desktop images are 1464x600 (2.44:1). Premium mobile images are 600x450 (4:3). A single composition cannot serve both breakpoints, and several modules need a separate mobile image for every panel.
- Dimensions printed by Amazon are MINIMUMS, not exact requirements. Oversize images are resized down to the module maximum. Undersize images are NOT scaled up, so undersize is the failure mode.
- Accepted file types are JPG, PNG and BMP. Animated images are not supported. Maximum file size 2 MB, minimum 72 dpi, RGB only, CMYK not accepted.
- Each module has its own per-field character limits, published by Amazon and varying by module.
