Spine width, full cover size with bleed and an ISBN barcode for your paperback. No sign-in, no data collected.

Work out the spine width and the full cover size of your paperback before you design the cover, and create the ISBN barcode for the back. - Spine width from page count, trim size and paper, in millimetres and inches - Full cover size with bleed: back cover, spine and front cover side by side - Safe area, whether the spine can carry text, and where the barcode field goes - ISBN-13 barcode (EAN-13) as a vector SVG or a PNG at 1200 dpi, with an optional 5-digit price add-on; ISBN-10 is converted automatically The figures are the print specifications ShelfPublisher uses to check every cover on upload, for international and European print on demand. Other printers can differ by fractions of a millimetre, so build the final cover on your printer's template. No sign-in, no tracking, no network requests: everything is calculated inside the popup.
