Special features of hardcover books
Compared to softcover books, hardcovers feature a number of noteworthy peculiarities...
First, covers are larger than the inner page block and the endpapers.
For example, if the text block and endpapers measure 21 x 29.7 cm, the finished book measures 21.3 x 30.3 cm, that is to say, 3 mm larger on the head, the tail and the fore edge.
In addition, the spine may be flat or rounded. Flat spine is more common, as it is generally cheaper than a rounded spine. The latter is used for more classical books, which are to be given a plus of elegance. On the other hand, at the top and bottom of the spine we find little pieces of cloth known as head and tail bands, and which "finish" it, so to say. Head and tail bands are available in assortments of a variety of colours.
