The PDF option includes multiple trim sizes, depending on your target form factor. The Word document has a fixed trim size (Letter). The ePUB and HTML lack trim sizes. Metric measures rounded to 2 digits in the table. All measures are in metric in the LaTeX macros. (US Customary Measures are defined by their Metric equivalent.) When calculating trim size, we compared commonly used sizes and those offered by KDP.

- Top and Inner margins are 2cm (~3/4").
- Outer and bottom margins are 17mm (~5/8").
- When attribute
bleed: trueis set, then the paper size and margins are increased by 3mm wide and 6mm high. (I don't think we can bleed an image, though.) - Set attribute
crop: trueto see what a given size looks like scaled properly on a letter-sized printout.
Warning: Failure to use one of the listed trim sizes will cause the compilation to fail. Defaults to trimsize: Trade.
