# The barcode area on a KDP cover

Where KDP puts the barcode, how much room to leave and what to do if you have your own.

KDP prints a barcode on the back of every paperback and hardcover. If your design puts something important in that spot, the barcode covers it.

## How much room to leave

|  | Width | Height |
| --- | --- | --- |
| Suggested box | 2 in | 1.2 in |
| Smallest KDP accepts | 1.4 in | 0.8 in |

## Where it goes

On a paperback the box sits in the lower right of the back cover, 0.25 in from the spine fold and 0.25 in from the bottom trim. On a hardcover it sits 0.375 in from the bottom. Keep that corner a plain, light area with no text.

> In kdpbookai the cover layout keeps the barcode box clear, and the checks before download flag anything placed over it. A cover with something in the barcode area is one of the [common rejections](https://kdpbookai.com/guides/common-kdp-rejections).
