Three bindings cover almost every printed book. A stapled booklet is folded sheets with two wires through the fold, 8–64 pages in fours. A paperback is glued leaves with a card cover trimmed flush, with hinge scores by the spine. A hardcover is a sewn block, rounded and backed, cased into boards that overhang the pages, with a groove at each board. This mockup builds whichever you pick that way.
The spine comes from the page count and the paper caliper, and the cover's spine area follows; the panel shows the width built. Eight presets run from A6 pocket to A4; the sliders cover 80–330 mm.
Five papers from bright white to kraft, a matte-to-glossy laminate, and the open book arches its pages rather than lying flat, because paper doesn't stretch.
From the page count and the paper thickness, plus the cover; the panel shows the result and it changes as you move either slider.
Yes. Each product has sliders for its main dimensions and presets for the common sizes; everything else, such as wall thickness or spine width, follows from them.
The Artwork panel shows each area's print size in millimetres for the current settings; prepare the file at that size, at 300 dpi if it is for print too.
