A mass-market paperback is a small, usually non-illustrated, inexpensive bookbinding format. This includes the UK A-format books of 110 mm Ã 178 mm (4.3 in Ã 7.0 in) and the US pocketbook format books of a similar size.
Unless yours is a specialty book which requires a unique size or shape, we recommend that you choose a standard trim size, which is commonly accepted and most economical. 1  The only real rule is that mass market books have to be 4-3/4â³ x 7â³. 2  Trade paperbacks, a pretty loose category of books, are often in the 5-1/2 x 8-1/2 to 6 x 9 range.
