Trim size moves the most
Widening the page increases the words each line holds and the lines each page holds at the same time, so it compounds. Going up one standard format is usually the largest single reduction available.
Print-on-demand charges you by the page, so this page count reducer treats every interior decision as a pricing decision as well. Change a trim, half a point of type or one step of leading, and watch the unit cost and the royalty per copy move in real time.
Enter your manuscript and current layout, then read the comparison table underneath.
Print-on-demand pricing is brutally simple above a certain length: a fixed handling charge plus a fee for every single printed page. That means the layout choices most authors treat as aesthetic, such as how big the type is, how much air sits between the lines and how wide the page is, are the exact things that determine what each copy costs to manufacture.
The effect compounds. Shaving forty pages off a four-hundred-page book takes roughly fifty cents off the unit cost, and that fifty cents lands straight in your royalty because your list price has not moved. Across a modest run of five hundred copies you have recovered more than most authors spend on formatting in the first place.
None of this is licence to make a book unreadable. There is a floor below which type is too small, leading too tight and margins too mean, and readers punish books that cross it. The skill is finding the point where the page still breathes and the printer stops charging you for air.

Line spacing rarely gets questioned yet it directly controls how many lines fit in the text block. Dropping from relaxed to normal spacing can remove ten per cent of the extent with almost no loss of comfort.
Moving from eleven and a half point to eleven feels imperceptible to a reader and typically removes several per cent of the page count. Two small changes together often beat one drastic one.
Short books under a hundred and ten pages are billed at a flat rate, so trimming pages below that threshold saves nothing at all. Above it, every page you remove has a direct cash value.

Approximate effect of each change on a 300-page trade paperback, holding everything else constant.
| Lever | Typical change | Pages saved | Reader impact |
|---|---|---|---|
| Trim 5.5×8.5" to 6×9" | One format wider | 8 to 12% | None; still a standard shelf size |
| Trim 5×8" to 6×9" | Two formats wider | 20 to 25% | Book feels less pocketable |
| Type 12 pt to 11 pt | One point smaller | 15 to 18% | Minimal for adult readers |
| Type 11.5 pt to 11 pt | Half a point smaller | 8 to 10% | Effectively invisible |
| Leading 1.5 to 1.15 | Two steps tighter | 20 to 25% | Noticeable but still comfortable |
| Leading 1.25 to 1.15 | One step tighter | 6 to 8% | None in practice |
| Chapter openings | Recto-only to any page | 2 to 4% | Slightly less formal structure |
| Margins | Reduce outer by 0.25" | 3 to 5% | Page can start to feel crowded |
For black-ink books sold in the US, anything from twenty-four to one hundred and eight pages carries a flat charge of $2.15. From one hundred and ten pages upwards it becomes a fixed $0.85 plus $0.012 for each page. Colour interiors and other marketplaces use different rates.
On Amazon's US paperback store you keep sixty per cent of the list price if the book is priced at $9.99 or above, and fifty per cent below that, with the printing charge deducted from your share in both cases.
Sometimes, but price affects demand and page count does not. Reducing extent increases your margin without asking a single reader to pay more, which makes it the safer of the two levers to pull first.
At half-point steps within the normal adult range, almost never. What readers do notice is a page that feels dense overall, which is usually caused by tight leading and narrow margins combined rather than by type size alone.
Only the avoidable ones. Starting every chapter on a right-hand page creates a blank verso roughly half the time, and relaxing that convention genuinely reduces extent. Structural blanks in the front matter should stay.
The principle holds but the numbers differ. Hardcover has a higher fixed charge and different page thresholds, and most printers set a minimum page count for case binding, so run the specific figures for that edition separately.
Yes, by uploading a reformatted interior. Be aware that the new page count changes your spine width, so the cover has to be rebuilt at the same time or the file will fail review.
Ten points is generally regarded as the practical floor for a full-length adult book in a serif face, and even then it depends heavily on the typeface. Large-print editions work at fourteen points or above and follow a completely different economic model.
Our typesetters rebuild the page from the grid up, adjusting measure, leading, margins and chapter structure to bring the extent down while the book still reads like something a publisher produced.
