Choose a KDP check
KDP book setup calculator
Calculate KDP paperback or hardcover page, margin, spine, and full cover dimensions in inches, millimeters, and pixels. Paperback results use published inputs; hardcover results are estimates to confirm with KDP.
KDP metadata checker
Check a KDP title, subtitle, description, and seven keyword fields for documented formatting issues and local review prompts. A clean result is not KDP acceptance.
KDP royalty calculator
Estimate US KDP royalty per sale for a paperback, hardcover, or eBook. Compare rate bands, printing or delivery costs, price floors, ad headroom, and monthly copies. Local estimate, not KDP acceptance.
KDP PDF preflight checker
Check a KDP interior or paperback cover PDF locally against selected trim, bleed, and cover settings. See page-level measurements and possible issues. It cannot guarantee KDP acceptance.
KDP image DPI checker
Check a JPEG or PNG in your browser. Find its effective resolution at your intended print size and its maximum size at 300 DPI for KDP print books.
KDP page count estimator
Estimate a likely KDP print page range from words, trim, typography, margins, chapter starts, images, and front or back matter. Final pagination still comes from the typeset PDF.
KDP payment date calculator
Estimate your KDP payment month from reported earnings and distribution type. See payment conditions and delivery times after Amazon issues payment.
