KDP vs IngramSpark Print Specifications
What It Means
Amazon KDP and IngramSpark both offer print-on-demand publishing, but their print specifications differ in several important areas.
Understanding these differences prevents upload failures and template mismatches.
Why It Matters
A file that works for one platform may still fail on the other if trim support, margin rules, or template assumptions do not match. Comparing specs before export helps avoid rework when publishing across platforms.
Trim Size Comparison
| Platform | Common Trim Sizes |
|---|---|
| KDP | 5x8, 5.25x8, 5.5x8.5, 6x9 |
| IngramSpark | Wider selection including 6x9, 7x10, 8.5x11 |
Bleed Requirements
Both platforms commonly require 0.125 inch bleed.
Margin Requirements
Margins vary depending on page count.
Typical ranges:
| Page Count | Inside Margin |
|---|---|
| 24-150 | 0.375 in |
| 151-300 | 0.5 in |
| 301+ | 0.625 in |
PDF Requirements
Both platforms require:
- embedded fonts
- 300 DPI images
- correct trim size
- no scaling
Example
Assume a paperback is prepared first for KDP and then uploaded to IngramSpark using the same files. If the trim size or template assumptions do not match the second platform, the cover spread and interior geometry may need to be rebuilt even when the PDF itself looks correct.
Common Mistakes
- Assuming one template works equally for both platforms.
- Reusing cover files without checking trim support.
- Comparing trim names without verifying exact dimensions.
- Ignoring page-count-dependent margin changes.

FAQ
Are KDP and IngramSpark bleed rules identical?
They are often similar, but workflows and template expectations can still differ.
Can one interior PDF always be used for both platforms?
Not always. Compatibility depends on trim, margins, and other platform-specific settings.
What should I compare first?
Start with trim size, page count assumptions, cover template logic, and margin rules.
