Open tool

Vellum for Windows

Vellum doesn't run on Windows — and the usual answer is buying different desktop software. The browser needs no port.

Open tool

KDP margin checker

Every margin calculator repeats Amazon's table. The question that gets books rejected is whether your PDF actually meets it.

Open tool

Word count to book pages — measured, not estimated

Most words-per-page tables are guesses. These numbers come from actually typesetting manuscripts at each trim size.

Open tool

KDP trim sizes, and how to choose one

The trim you pick changes your page count, your printing cost per copy, and how the book reads in the hand.

Open tool

The classic compact fiction trim — between mass-market and trade — typeset with exact geometry and a gutter matched to your page count.

The digest trim — memoir and general non-fiction's favorite middle ground — with exact geometry and a preflight that proves it.

Open tool

A5 book formatter

The international trim — 148×210mm — typeset with exact metric geometry, for KDP and non-US printers alike.

Open tool

Fantasy novel formatter

Fantasy runs long — and long books are where gutter math, page limits and spine width start to bite. Typeset with the geometry handled.

Open tool

Non-fiction book formatter

For text-led non-fiction — self-help, business books, essays, practical guides — typeset from the Word file you already have.

Open tool

A Vellum alternative that runs in the browser

Vellum is excellent — and $249, Mac-only, and another app to learn. The alternative: upload the manuscript, download the book.

Open tool

An Atticus alternative for finished manuscripts

Atticus wants to be where you write. If your book is already written in Word, you need a typesetter — not a second home for your text.

Open tool

A Kindle Create alternative that doesn't lock you in

Free has a shape: Kindle Create's output works only on Amazon. If you want files you own — standard EPUB, print-grade PDF — that's the alternative.
