# Large trim

**Definition.** Large trim is KDP's class for print books wider than 6.12 in or taller than 9 in. Large-trim books cost more to print than regular ones: on Amazon.com a black-ink large-trim paperback of 24 to 110 pages costs $2.84 to print, against $2.30 for a regular trim.

Sources checked October 20, 2026. Figures: KDP's paperback royalty rates, trim classes and spine figures, as of October 2026; KDP's Amazon.com paperback printing costs, as of October 19, 2026.

## How it works

The class depends only on the two measurements. A 6 x 9 inch book sits exactly on the line and is regular; anything beyond it in either direction is large. Above the flat band, both classes pay a fixed $1.00 plus a per-page charge, $0.012 a page for regular trim and $0.017 for large, so the gap widens as the book gets longer. Because KDP takes printing cost out of the royalty, a large trim pays less per copy at the same list price and needs a higher minimum price.

## An example

Take a 200-page black-ink paperback listed at $14.99 on Amazon.com. In a regular trim it costs $3.40 to print and pays $5.59 a copy; in a large trim it costs $4.40 and pays $4.59. Same book, same price, $1.00 less a copy, only because the page is larger.

## Common mistakes

Choosing 6.14 x 9.21 inches as "about the same as 6 x 9": it is just over the width line, so KDP lists it among the large trims. Picking a large trim for a text-only book that would read as well in a regular one. And reusing a price from a regular-trim edition without recalculating the royalty for the larger page.

## Questions

**Is 6 x 9 a large trim on KDP?** No. Large trim starts above 6.12 in wide or 9 in tall, and 6 x 9 is exactly 9 in tall, so it is a regular trim.

**Why would anyone choose a large trim?** Some books need the page: workbooks with room to write, recipe books, photo-heavy guides and children's books. The cost is a higher printing charge on every copy.
