A large-format book gives images, drawings or documents more physical room, and every gain in scale changes how the object is held, opened, stored and made. Printing it is not the same as printing a large flat sheet: format, folded sections, binding and cover have to work as one construction.
Scale that answers the content
The useful question is what becomes readable at the proposed size. Architectural drawings may need fine annotation to stay legible, photographs may depend on immersion – as in Fokion Zissiadis's Morocco, an XXL book we printed for teNeues – and an archive on comparison between documents. If enlargement adds empty area without revealing more or strengthening the sequence, the format is carrying symbolism rather than doing editorial work.
Closed dimensions are best considered alongside the open spread. A wider page gives an image breadth while pushing its far edge out of comfortable reach; a taller one suits vertical work but changes the reader's posture. On a larger leaf, stiffness, grain direction, weight and extent all affect turning and opening, and a stock that feels balanced in a small sample can become stiff or slack at book scale.
Construction before refinement
A case, jacket or slipcase can protect a heavy book and support its presentation, while adding a step before the pages. The balance depends on distribution, shelving and frequency of consultation.
Images that cross the centre are the most exposed part of a large book. Page curvature near the binding can interrupt a face, a horizon or a line of text. Knowing the likely opening before compositions are fixed lets designers move key details away from the gutter while the layout is flexible.
