Decisions, Decisions
(where would we be without decisions?)
When it comes to choosing the form in which your book will be sent forth into the world–hardcover, paperback, small, or large–it’s the rare author who has considered the book’s actual trim size. Those other elements? They’re easy to visualize in your head, to picture your book as taking one such form. Trim size is not so easy, in part because many authors don’t even know what the term means.
Thanks to Dictionary.com, we can safely interpret trim size to mean the page area left after final production is completed–which is not the same thing as the page area throughout the printing process. While a book is being printed, the pages are slightly larger than their final size. Once your content has been printed, the pages are cut down to their final size–their trim size.
Depending on which self-publishing company you choose, you ought to have a choice of trim sizes to select from. Print on Demand (POD) options will often constrain your choices simply because each size uses its own machinery, so the more sizes on offer = the more expensive the machinery is to purchase and maintain for the operator, and ultimately, the end user–you.
There are so many sizes to choose from, it almost boggles the mind.The most common trade paperback sizes, for example, run from 6″ by 9″ to 5.5″ by 8.5″, but you’ll also see 5.25″ by 8″ and 5″ by 8″ in some POD services. It’s not unheard of to choose even larger sizes–6″ by 9″, 7″ by 10″, 8.25″ by 8.25, or even 8″ by 10″–especially if you’re working within the children’s picture book or technical manual markets.
Think about how your book will be used, and by whom, and what the typical expectations are within a genre. Fiction titles typically run in smaller trim sizes, since readers typically read them for pleasure–whether on the train to work in the morning, or while sitting on the back porch. Nonfiction titles, including memoirs and the ever-growing Creative Non-Fiction (CNF) field typically run in the middle of the pack–unless they’ve been penned by someone famous, like a film or a football star. Those are often oversized, just like the personalities they describe. Technical manuals, cookbooks, photography tabletop books, and children’s picture books are always the largest books on the shelf–and often, they are used while lying flat on a table or the floor.
I guess my recommendation is rather simple: take a ruler with you to the bookstore and library. Measure the books that fall within the “if you like my book, you might also like X book” category, whether you’re thinking of similarities in genre or thematic content. Weigh it in your hand. Are you more likely to pick up the hardcover or the paperback of that book? And don’t just measure the outside cover. Look inside–at the trim size, the the margins. It may not be an easily quantifiable thing, but readers are most likely to buy books that strike them as visually balanced and attractive–and the trim size of a book contributes to this a great deal!
