Trim size refers to the dimensions of a book after it has been printed and trimmed. Choosing the right trim size is important because it impacts the overall look and feel of your book. Consider the page count, print cost, target audience, and publishing goals when selecting a trim size.
Some of the most common trim sizes for non-fiction business books are listed below:
| Size | Description | Hardcover Option Available on KDP |
| 5 x 8 | Good choice for short books | No |
| 5.5 x 8.5 | Popular trim size for fiction and non-fiction books | Yes |
| 6 x 9 | Commonly used trim size that allows for larger fonts and more spacious layouts; is a good option for books with images or diagrams. | Yes |
| 8.5 x 11 | Use for workbooks and planners. | Yes |
8 x 8 or 10 x 10 can work well for children’s books, art books, and photography books because they allow for larger images and more creative page layouts.
