What DPI Should Images Be for KDP?
For a professional-looking print book on Amazon KDP, images should be at least 300 DPI (dots per inch). This resolution ensures that images appear sharp and clear when printed. Lower DPI can result in pixelated and blurry images, detracting from the quality of your book.
Why 300 DPI?
300 DPI is the standard for print because it provides a good balance between image clarity and file manageability. It ensures that the details in illustrations and graphics are preserved, offering readers a visually appealing experience.
#### Example of DPI Impact
Consider an image that is 4 inches by 6 inches:
- 300 DPI: This image will have a resolution of 1200 x 1800 pixels, providing crisp and clear details.
- 150 DPI: Reducing the resolution to 600 x 900 pixels might make the image appear blurry when printed, particularly for detailed graphics.
- 72 DPI: At this resolution, the image is only 288 x 432 pixels, which is suitable for web but not for print, leading to a significant loss of detail.
Edge Cases in DPI
- Line Art and Illustrations: These may require higher DPI (600 DPI) to maintain sharpness and detail.
- Photographs: Generally, 300 DPI is sufficient unless the image is intended to be a full-page spread, in which case ensuring the original image is high resolution is critical.
How to Properly Place Images in a KDP Interior
When placing images within your KDP interior, it's crucial to adhere to KDP's formatting standards to avoid issues during the upload and review process.
Placement Guidelines
- Margins: Keep images within the set margins of your book format. This prevents images from being cut off during printing. For example, if your book has a margin of 0.5 inches, ensure all parts of your image are at least 0.5 inches away from the edge.
- Bleed: If images extend to the edge of the page, ensure they include bleed margins of at least 0.125 inches on all sides. This means if your page size is 6 x 9 inches, the image should be 6.25 x 9.25 inches to accommodate the bleed.
What to Do If Images Are Misplaced
- Check Margins and Bleeds: Use layout software like Adobe InDesign to check and adjust margins and bleeds.
- Re-upload: If your submission is rejected due to image placement, correct the margins and bleed settings and re-upload the file.
For more detailed guidance, see our article on KDP Margins and Bleed Requirements Explained.
Managing File Size for KDP Interiors
KDP imposes a file size limit of 650 MB for interior PDFs. Large image files can quickly increase your PDF size, so it's important to optimize images without sacrificing quality.
File Size Tips
- Compress Images: Use tools like Adobe Photoshop or free online services to reduce file size while maintaining 300 DPI. For instance, reducing the quality setting of a JPEG from 100% to 85% can significantly decrease file size without noticeable quality loss.
- File Format: Save images as JPEG or PNG, as these formats balance quality and file size effectively. JPEG is ideal for photographs, while PNG is better for images with transparent backgrounds.
#### Step-by-Step Compression Example
- Open Image in Photoshop: Go to `File > Open` and select your image.
- Adjust Image Size: Go to `Image > Image Size`, set the resolution to 300 DPI, and adjust dimensions if necessary.
- Save for Web: Go to `File > Export > Save for Web (Legacy)`. Choose JPEG format, set quality to 85%, and save the image.
What to Do If File Size Exceeds 650 MB
- Reduce Image Count: Consider removing non-essential images.
- Further Compression: Use additional compression tools like TinyPNG or ImageOptim for further reductions.
Creating Print-Ready PDFs
Once your images are correctly formatted and placed, compile your manuscript into a print-ready PDF. Ensure your document follows KDP's requirements for trim sizes, margins, and bleed.
Step-by-Step PDF Creation
- Compile in Layout Software: Use Adobe InDesign or similar to arrange your book layout.
- Export to PDF: Go to `File > Export`, select PDF format, and ensure settings include 300 DPI for images.
- Check Settings: Ensure the PDF includes crop marks and bleeds if needed.

What to Do If PDF Does Not Meet Standards
- Review PDF Settings: Double-check your export settings to ensure compliance with KDP guidelines.
- Re-export: Make necessary adjustments and export the PDF again.
Common Mistakes in Adding Images to KDP Interiors
Avoid these pitfalls to ensure a smooth publishing process:
- Low DPI: Always check the DPI before uploading. Use tools like Photoshop to verify and adjust DPI.
- Incorrect Placement: Images that don't adhere to margin and bleed guidelines can cause rejections. Always preview your layout in software to ensure correct placement.
- Large File Sizes: Keep your PDF under 650 MB to avoid upload issues. Use compression techniques as discussed to manage file size.
