Amazon A+ Module Slicer
Upload one tall poster image. The tool creates exact borderless Amazon A+ desktop and mobile modules. The last module is padded with white if the image does not end exactly on a module boundary.
Show full sizing reference and the rule behind it
One rule avoids all white space: the poster width must match the module width exactly, and the total height must be an exact multiple of the module height. White padding only appears when the height does not land on a clean module boundary. Amazon module dimensions are minimums, so the 2x sizes below are recommended for sharpness after Amazon compression.
Desktop poster
Module 1464 x 600 px (aspect 2.44:1). Width 2928 px at 2x, height a multiple of 1200 px:
| Modules | 2x recommended | 1x minimum |
|---|---|---|
| 3 | 2928 x 3600 px | 1464 x 1800 px |
| 4 | 2928 x 4800 px | 1464 x 2400 px |
| 5 | 2928 x 6000 px | 1464 x 3000 px |
| 6 | 2928 x 7200 px | 1464 x 3600 px |
Separate mobile poster (optional)
Module 600 x 450 px (aspect 1.33:1). A separate mobile poster is split into equal bands, so it must be 1200 px wide at 2x with a height that is a multiple of 900 px. The number of bands must equal the desktop module count:
| Modules | 2x recommended | 1x minimum |
|---|---|---|
| 3 | 1200 x 2700 px | 600 x 1350 px |
| 4 | 1200 x 3600 px | 600 x 1800 px |
| 5 | 1200 x 4500 px | 600 x 2250 px |
| 6 | 1200 x 5400 px | 600 x 2700 px |
If you upload only a desktop poster and let the tool build mobile automatically, you can ignore the mobile table. The mobile handling setting below resolves the module count difference for you, either by scaling the desktop down to match (default) or by filling the extra mobile slots with white.
