Trim Sizes

Due to the range of physical book form factors, the PDF compilation includes a trimzize option. The Word document has a fixed trim size (Letter, 1″ margins) to support editor collaboration. The ePUB and HTML lack trim sizes.

When calculating trim size, we filtered commonly used trim sizes against those offered by KDP. The resulting set of trim sizes are listed below. Metric measures rounded to 2 digits in the table. All measures are in metric in the LaTeX macros. Since US Customary Measures are defined by their Metric equivalent, the PDF trim size is defined in metric.
