Hardcover needs extra template checks

The book block still has a thickness, but hardcover production can add hinge, wrap, board, and jacket considerations.

• Use the calculator to understand the approximate book-block thickness.
• Do not use a paperback spread as a final hardcover file.
• Confirm case, hinge, wrap, and jacket dimensions with the selected printer.

Brief the designer with assumptions

A clear early estimate helps with composition, but the final design should wait for printer-specific requirements.

• Share page count, paper thickness, trim size, and binding type.
• Name whether it is case laminate, jacketed hardcover, or another format.
• Keep spine text flexible until the final template is available.
