Your book has been written, rewritten, beta read, edited and reedited to within an inch of its life. Now it is time to design and layout the interior. One of the first decisions you will be asked to make is the height and width of the book. This is called the trim size. So you go to your bookshelf and pull down your favorite four books and notice that they are all 6x9. There! Decision made! But not so fast.
Here are the questions you should ask yourself when choosing your trim size based on other books.
- Are the books you're comparing to in your same genre?
- Are the books the same format? Is yours a paperback and the one you're holding a hardcover?
- Is the book you're holding more than 2 years old?
- Is the book you're holding published by an established publisher?
Here is the thing that stumps a lot of us. We like what we like, but often our tastes are not quite in line with what people are buying today. (I know . . . it depresses me too.)
So instead of turning to your own bookshelf, when choosing a trim size of a book you are about to publish; the decision should be based on these factors instead:
- What is the best trim size for YOUR category according to customer purchase habits within the last year?
- What sizes are established publishers using for their books in your category?
- How will the trim size affect a book industry professional's opinion of your book?
- Does the trim size you chose dramatically impact the page count and print pricing of your book?
There are a few steps you can take to determine the best trim size for your book. I can't tell you what trim size you should make your book. As a publisher, that is your call. However, each month, I go through the USA Today bestseller list, the Amazon top-sellers, and the New York Times bestseller lists and compile a list of the most common trim sizes they all have. The list below will tell you what sizes more people are purchasing in your category at the publication of this blog post. This list also tells you what sizes established publishers are choosing based on their research. (I LOVE borrowing research from companies that have a lot more money than me.)
The real purpose of this list is to allow you to see what established publishers (best-selling publishers) are doing with their trim sizes in your category. Why do we care? Because book buyers, booksellers, librarians, even some savvy consumers are lead and “trained” to think of professionally published books as the standard. If Random House, Simon & Schuster, and HarperCollins all agree that 6x9 is not a great trim size for general fiction paperbacks, then your 6x9 general fiction paperback will look a little out of place.
One reason to choose one trim size over another would be print pricing. For example, a 6x9 book will take up fewer pages than a 5x8 book. If the smaller trim size pushes your page count out to a point where you cannot afford to print the book, then the larger print size makes more sense. But just defaulting to a certain trim size because you like the size or you think that it will remind readers of a hardcover is not a great idea.
I have compiled for you a list of the most common categories, and I have researched the most common trim sizes for the bestselling books in each category. Many of the trim sizes were so close to sizes available at IngramSpark that if they were a 10th of an inch or less different, I referenced IngramSpark's available sizes.
What is clear, is that if you want to emulate a successful publishing house (hint: you do), then you should consider the following trim sizes.
- General Fiction 5.25x8
- General Non-Fiction 5.5x8.5
- Thrillers/Mysteries 5.25x8
- YA General Fiction 5x7
- YA Dystopian, Fantasy, and Sci-Fi 5.5x8.5
- General Self Help 5.25x8
- Inspirational/Spiritual 5x8
- Memoir 5.25x8
- Reference 6x9 and 7x10
- Middle-Grade Fiction 5x8
- Picture Books PB 8x8
- Business 5.5x8.5 OR 5.25x8
The bottom line is this…
Go to your local bookstore and get online. See what the major houses and your biggest competition is doing with their trim sizes. You can still choose to print in any size you wish, but you should know what the market is looking for right now. Buyers are human and like things that look like previous successes. Why not borrow from that phenomenon where you can?
