KDP Paperback Publishing Services

A KDP paperback needs an interior PDF and a wrap built from their calculator after the pages are final. The minimum margins are a floor. A thick book needs a wider gutter. We order a proof before the listing is the one customers see.

A paperback cover being checked
Publishing and ordering a proof are two different buttons.

The paperback spec

Their template, your final count, a barcode that matches the ISBN.

Trim, paper color, and bleed are chosen first. Bleed is for art that runs off the edge. A novel with no art should not be a bleed file. The cover calculator then gives a wrap for that count and that paper. Cream and white do not share a spine width. Spine text comes off if the book is too thin. If we embed a barcode, it has to be the right ISBN, in the quiet zone their template leaves. If we let KDP add the barcode, we leave that zone empty.

The interior needs embedded fonts and page numbers that are not in the gutter. KDP minimum inside margin is not enough for a long book. We widen it. Then we upload, order a proof, and read the proof for the bind and the hinge. Going live because the previewer looked fine is how the first buyer becomes the proofreader.

Order of the work

Interior locked, template downloaded, proof in hand.

  1. 01 Trim and paper Size, cream or white, bleed or not. Print cost noted.
  2. 02 Interior Embedded fonts, gutter for the thickness, no crop marks.
  3. 03 Wrap From the calculator for that exact file. Spine text only if it fits.
  4. 04 Proof, then live A printed copy. Then the publish button, after you have seen it.

The listing beside the file

The form has to describe the PDF you uploaded.

A trim selected on the form that does not match the file is a rejection, or a book that looks scaled.

What we upload

Two PDFs and a price.

Change the interior later and the cover is invalid. We regenerate the template rather than stretch the old spine.

Interior PDF The exact file the page count came from.
Cover PDF Full wrap, barcode zone respected.
Listing Description, categories, and the trim selected to match.

Decisions

ISBN and proof, before the upload.

01

KDP free ISBN

Fine if this paperback will only live on Amazon. You cannot reuse it at Ingram.

02

Your ISBN

If you may also print elsewhere. The barcode and the KDP field use that number.

03

Proof

Always, for a first edition. Author copies of a live book are not a proof. They are stock of a book customers can already buy.

House rule

What we will not send KDP as a paperback.

A front cover and a Word document are not the pair they print.

Before the calculator

Questions the paperback raises.

How thick does a book need to be for spine text?

KDP will tell you on the template once the count is in. Below their minimum, we leave the spine blank. Squashed lettering is worse than none.

Can I update the file later?

Yes. If the page count changes, the cover is rebuilt. If it does not, we replace the interior and check the preview again.

Who owns the wrap?

You do. Interior, cover, and the template notes.

When the text is frozen

Send the manuscript and the trim you want.

We will tell you if that trim can hold the page count. Call (833) 688-4166 or write [email protected].
