Free author tools
Our free tools for authors turn guesswork into numbers: what a book might earn, how many pages it will run, when each stage must start and how wide the spine needs to be. They take a minute to use and cost nothing. They give estimates, not promises, so treat the results as a planning aid and confirm final specs with your printer or retailer before you commit to anything.
Estimate what you earn per copy across print and ebook at different list prices.

Here is what each tool does and when it helps most.
Estimate what you earn per copy across print and ebook at different list prices. It is useful when you are choosing a price, comparing paperback with ebook, or deciding how many copies you would need to sell to cover your costs. Always check the current rules on pricing your book at the retailer, because fees and printing costs change.
Turn a word count into an estimated page count and reading time for common trim sizes. It helps you judge whether your manuscript is a slim paperback or a long hardcover before you commission design or quote printing. Remember that a page count also depends on font size and line spacing, so your final layout may differ.
Enter your target launch date and work backward to see when editing, design, formatting and pre-orders need to begin. A full publishing project typically takes 4 to 8 weeks, so late starts are the usual cause of missed dates. The tool also helps you leave room for revision rounds and pre-order setup.
Calculate spine width and full-wrap cover dimensions from your page count. Spine width depends on paper stock, so the printer's own template is the final word. Use the result to brief your designer, not to send files to print. See the specs at IngramSpark.
This tool highlights long sentences, repeated words and passive voice in a short sample, which is a handy self-check before editing. Use it to tidy a chapter before you send it to a professional, so your editor spends time on bigger things. It does not replace a human editor from our book editing services, and it does not follow every house style, such as the Chicago Manual of Style.
This tool helps you brainstorm retailer search terms and categories for your book. Good keywords and categories make a book easier to find, and they cost nothing to improve. Plan a list of terms a reader might type, then match them to the categories you choose at each store. For a full launch plan, see our book marketing services.
Paste your text to count double spaces, straight quotes, stray tabs, doubled hyphens and extra blank lines, then copy a cleaned version. It saves your typesetter time and keeps your book looking professional.
Answer a few questions and get a structured retailer blurb with a hook, a story or promise and a call to action. Treat it as a first draft and rewrite it in your own voice.
Get the Flesch reading ease score, the grade level, the average sentence length and the reading time of a sample, so you can tune your writing for your readers.
Validate an ISBN-10 or ISBN-13, convert between the two or work out a missing check digit. Real ISBNs are issued by your national agency, such as isbn.org in the United States.
Compare print on demand with a short offset run and find the quantity where offset becomes cheaper. The default rates are placeholders, so replace them with real printer quotes.
Split a target word count into chapters, evenly or shaped like a story arc, and see how many days the draft will take at your daily pace.
Get title and subtitle ideas built from patterns readers recognize. Use the list to spark your own title and test your shortlist on real readers.
Turn a few facts into a short, medium and long author bio in first or third person, ready to edit and use on retailer pages and your website.
Tick off every step from manuscript to launch day. Your progress is saved in your browser and the list prints cleanly.
Download an SVG cover template with spine, bleed, safe zone and barcode area drawn to your trim size and page count. Confirm the final template with your printer.
Publishing a book also means handling files and images. The free utilities at SEO Site Checker cover those jobs, and the ones below suit authors best. They are run by a separate site, so check their terms before you upload anything private.
The tools work best in sequence. Plan with the chapter word count planner, then check your draft with the line edit report, reading level checker and manuscript format checker. Start with the word and page count, because length drives nearly everything else: print cost, price and schedule.
Next, run the publishing timeline to set realistic dates. Then use the cover size calculator once your page count is firm, and finish with the royalty calculator to test prices. The keyword planner comes last, just before you write your book description. Revisit them whenever a number changes, such as a new page count after editing. The book publishing blog explains each step in more detail.
A calculator can tell you the spine is 0.6 inches wide. It cannot design the cover, typeset the pages or schedule the launch. Our team handles book formatting, cover design and publishing as part of every package, so you do not have to chase specs yourself. Ask for a quote, and we will fix the price in writing before any work starts.
Yes. Using the tools costs nothing and does not oblige you to buy anything from us.
