What Are KDP Margins and Bleed Requirements?
When publishing on Amazon KDP, precise margins and bleed specifications are crucial to ensure your book is printed correctly. Margins are the space between your content and the edge of the page, while bleed refers to the extension of images or backgrounds beyond the trim edge, allowing for clean cuts.
How to Calculate KDP Margins
To avoid rejection, adhere to the following KDP margin guidelines:
- Non-Bleed Pages: Maintain a minimum of 0.125 inches from the content to the edge of the page.
- Bleed Pages: Extend your content 0.125 inches beyond the final trim size.
- Gutter Margin: For binding, include at least 0.375 inches in the interior margin.
Table: KDP Margin Requirements
| Requirement | Specification |
|---|---|
| Non-Bleed Margin | 0.125 inches |
| Bleed Extension | 0.125 inches |
| Gutter Margin | 0.375 inches |
Step-by-Step Margin Calculation
- Determine Your Book's Trim Size: The trim size is the final size of your book after it has been cut. Common sizes include 6" x 9" or 8.5" x 11".
- Apply Non-Bleed Margin: For a 6" x 9" book, the content area should be 5.75" x 8.75" to account for a 0.125" margin on all sides.
- Add Gutter Margin: If your book is 200 pages, you'll need a 0.375" gutter margin. This means your interior content width should be 5.375" to accommodate the gutter.
- Calculate Total Page Size with Bleed: If your book includes bleed, add 0.125" to each side of the trim size. For a 6" x 9" book, the total page size becomes 6.25" x 9.25".
Worked Example
Suppose you're publishing a 300-page novel with a trim size of 5" x 8". Here's how you would set it up:
- Non-Bleed Content Area: 4.75" x 7.75"
- Gutter Margin: 0.375"
- Bleed Page Size: 5.25" x 8.25"
What Are Bleed Settings in KDP?
The bleed setting refers to extending images or backgrounds beyond the trim size to prevent white edges after trimming. Set your document to include bleed if your design elements reach the edge of the page. This is especially important for full-page images or backgrounds.
Setting Up Bleed in Design Software
- Adobe InDesign: Go to File > Document Setup and enter 0.125" for the bleed settings.
- Microsoft Word: Use a larger page size and extend your design elements to the edges.
- Canva: Enable bleed under the Resize option, adjusting your design to fit.
Why Is Bleed Important?
Bleed ensures that your printed pages have no unintended white borders. Without bleed, slight misalignments during printing could result in white strips along the edges, especially noticeable in image-heavy books.
Real-Life Example
Imagine a children's picture book with vibrant full-page illustrations. Without proper bleed, even a small misalignment could leave unsightly white edges, disrupting the visual flow and reducing the book's professional appearance.
