Free tools

Small tools for getting a book ready to publish. Each one runs in your browser: it’s free, it needs no sign-up, and nothing you type is sent anywhere.

• KDP paperback margin calculatorThe minimum margins and gutter for your page count, the page size with bleed, the spine width, the cover size, the printing cost and your royalty.
• Quote and dash fixerCurly quotation marks, apostrophes, dashes, ellipses and no-break spaces in English or German style, for the blurb, the newsletter or the shop page.

Kernsetzer, the app, gets the margins and the quotation marks right by itself when it sets your book. The guide to formatting a KDP paperback walks through the rest. Sign up for the beta.
