In the age of Ozempic, the trend of smaller hardcover books is on the rise, with 5-by-8 trim sizes gaining popularity over the traditional 6-by-9. This shift is evident in the bestsellers at Book Soup, where books like "Strangers" and "Vigil" are embracing the smaller format. Industry experts like Gretchen Achilles from Farrar, Straus and Giroux note that the 5-by-8 size offers intimacy and a unique reading experience, particularly for genres like literary fiction and memoirs. Bookstagrammers and readers also appreciate the smaller hardcovers for their approachability and Instagram-friendly size, making them a sought-after choice for book lovers.
