Build your book-cover brief

Answer the questions below. We will calculate the cover measurements and turn your answers into professional instructions you can copy into ChatGPT. Fields marked * are required.

1. Printing measurements

Use the finished internal page size. Measurements must be entered in millimetres.

Use the final page count, including blank and preliminary pages.
Choose the paper stock for the internal pages. Its correct caliper will be used automatically to calculate the spine.
Calculated automatically from the cover type, page count and paper stock. This result cannot be edited or overridden.
Hardcover only. Choose whether the title and main front-cover artwork are centred across the complete panel or across the visible front-cover face after excluding the 7 mm hinge. Softcovers always use the complete front and back panels.

2. Exact front-cover wording

Enter the wording exactly as it must appear. ChatGPT will be told not to rewrite or invent it.

3. Creative direction

Plain descriptions are fine. The generated brief will convert them into professional design language.

List book titles, artists or styles. Upload any actual reference images directly to ChatGPT with the generated brief.

4. Back cover and spine

ChatGPT will be told never to invent an ISBN or fake barcode.

5. Files and final instructions

Examples: author photo, publisher logo, barcode image, illustration, brand colours or reference covers.
Collects book-cover details, calculates exact softcover or hardcover measurements, and creates a structured brief that customers can copy into their own ChatGPT account.
