Frequently Asked Questions
Quick answers about using our free KDP publishing tools.
Are all the tools on this site really free?
Yes. Every calculator and generator on KDPToolsPro — cover, spine, hardcover, barcode, printing cost, royalty, trim size, page count, niche finder, cover template and lorem ipsum — is 100% free with no registration required.
Will these dimensions be accepted by Amazon KDP?
Our formulas follow Amazon KDP's published cover and spine specifications, but we always recommend confirming your final file against KDP's own cover calculator before uploading, since requirements can be updated over time.
Do you store any of the numbers I enter?
No. Every calculation runs directly in your browser, and nothing you type into a tool is saved on our servers.
Which tool should I use first?
Most authors start with the Trim Size Calculator to choose a format, then the Book Page Calculator to estimate length, before finishing with the Cover Calculator and Royalty Calculator once the manuscript is finalized.
