Amazon KDP Barcode Placement Rules: Avoid Cover Rejections

Every paperback and hardcover book printed through Amazon KDP must have an ISBN barcode on the back cover. While Amazon can automatically generate and stamp a free barcode for you, placing critical artwork or text in that region leads to ruined covers and printing delays. Here are the exact specifications.

Where Does Amazon Put the Barcode?

Amazon places the barcode on the **lower right-hand corner of the back cover**. - The barcode area measures **2.0 inches (50.8 mm) wide by 1.2 inches (30.5 mm) high**. - It is situated **0.25 inches (6.4 mm) from the bottom trim line** and **0.25 inches (6.4 mm) from the spine fold**.

The Safe Zone Rule

Do not place any text, icons, author headshots, or critical design elements within this 2" × 1.2" rectangular zone. Background images or colors can extend through this area because Amazon will print a white opaque box over the background to ensure barcode scanners can read the stripes.

Providing Your Own Barcode vs. Amazon's Free Barcode

If you bring your own ISBN (from Bowker or your national agency), you can embed the barcode directly into your cover PDF. However, you must ensure: - The barcode is 100% black on a pure white background (RGB 0,0,0 on 255,255,255). - The resolution is at least 300 DPI vector lines to prevent scanner failure at retail checkout.

How KDPage Protects Your Barcode Zone

When designing in KDPage Studio, an interactive barcode box overlay appears on your back cover. It locks out text placement in that zone, ensuring your author bio and blurb remain perfectly legible.
