0/5Frequently Asked Questions
What are the most common reasons KDP rejects a book?+−
The top rejection reasons are: cover dimensions don't match the template (wrong spine width or bleed), interior PDF has wrong page count or trim size, low-resolution images (under 300 DPI), missing or incorrect ISBN placement, content that violates Amazon's guidelines, and metadata that doesn't match the book content.
How long does KDP review take?+−
KDP typically reviews and publishes books within 72 hours, but most books go live within 24-48 hours. If your book is flagged for manual review (common for AI-assisted content), it can take up to 5 business days.
Do I need an ISBN to publish on KDP?+−
No. Amazon provides a free ASIN for Kindle ebooks and a free ISBN for paperbacks and hardcovers. However, you can also use your own purchased ISBN if you prefer — this gives you more control if you plan to distribute through other channels.
What file formats does KDP accept?+−
For manuscripts: KDP accepts DOC, DOCX, KPF, EPUB, and PDF (for paperback/hardcover). For covers: PDF or JPEG/TIFF at 300 DPI minimum. The recommended format is PDF for both interior and cover to maintain exact formatting.
