Trim sizes

If you’ve taken my Publish It Yourself Course or read my book the Publish It Yourself Primer, you know a little about trim sizes. “Trim size” is one of those holdover terms left over from the days when analog printing was all there was. For efficiency, book pages were, and still are, printed on large sheets of paper. They come off the press, are stacked, and then cut, or “trimmed,” to size. Then they are gathered in book sets with all the pages in the right order. This work was originally done by highly-skilled printers, then later, computers helped to speed things up. Just like now.

The size of your book plays a part in how it’s perceived, in general and against other books in its genre. Not every country prints books in the same sizes used by American printers.

I asked Google Gemini whether I should consider re-designing the Touchwood Press 50 Fun Facts baseball books for international markets, now that baseball is rapidly growing as a global sport.

Gemini: While your 5″ x 8″ trim size is a classic, portable choice that works well in many markets, there are a few professional and logistical reasons you might consider adjusting it for international distribution—specifically if you are looking at the UK and Commonwealth markets.

Here is a breakdown of how trim sizes translate globally:

1. The “Trade Paperback” Standard

In the United States, 5″ x 8″ and 5.5″ x 8.5″ are standard for trade paperbacks. However, in the UK and Australia, the standard “B-Format” is slightly different:

  • UK B-Format: Approximately 5.1″ x 7.8″ (129mm x 198mm).
  • Your Current Size: 5″ x 8″ is very close to this, meaning it won’t look “wrong” on a shelf next to British sports books. It is actually a very safe “middle ground” size.
2. Industry Expectations by Category

According to the IngramSpark guide to popular trim sizes, different genres have “trained” readers to expect certain dimensions.

  • Reference & Nonfiction: Many international nonfiction titles lean toward 5.5″ x 8.5″ or 6″ x 9″.
  • Portability: Since your brand is built on being “pocket-sized,” staying small is a smart move. Moving to a larger size like 6″ x 9″ might alienate your current fans who value the portability.
3. Print-on-Demand (POD) Economics

If you use services like IngramSpark or KDP for international distribution, you should check if your specific size is “Standard” or “Custom” in those regions.

  • Distribution Reach: Most POD services offer 5″ x 8″ as a standard size globally. If you chose a highly unusual custom size, you might be restricted from “Expanded Distribution,” but 5″ x 8″ is widely supported.
  • Page Count & Pricing: If you change to a smaller size, your page count will increase, which can raise the print cost and lower your profit margin per book.
4. The “Look and Feel” Factor

As noted by Amy Collins, book buyers and librarians are often “trained” to recognize professional quality by the trim size. A 5″ x 8″ book:

  • Feels like a Mass Market or B-Format book in the UK.
  • Is perfect for “commuter reading,” which is a huge market in Europe and Asia.

Recommendation

I wouldn’t recommend changing it. Your 5″ x 8″ size is globally recognized as a standard portable format. Changing it for international markets would require you to manage multiple interior layouts (files) and different cover wraps for the same book, which increases your overhead and the risk of formatting errors. The “pocket-sized” branding is a unique selling point for a sports series—stick with it to maintain brand consistency across the globe.

Gee, thanks. I’ll stick with my current strategy.

There’s a lot I could unpack in AI’s comments, but that will wait for another post or book. Let us know if you have questions.

Good writing!

Yikes! Amazon raises prices.

Here is Amazon’s May 30, 2025, announcement: For the first time since starting print operations almost two decades ago, starting June 10, 2025, we are changing the royalty rate for books priced below certain list prices (e.g. less than 9.99 USD) from 60% to 50%. 

I have been in and around publishing long enough to understand that printing and binding a book is not cheap. In the pre-POD (print on demand) days, printers and publishers were compelled to produce print runs as large as possible in order to reduce per-book costs to a level that they and their customers could handle.

Back when I was in the textbook publishing business (the 1980s), tiny changes in the commodity price of lumber (used to make paper) and manufactured paper caused great angst in the C-Suites of the major publishers. These same economics usually made it impossible for authors to self-publish because the print runs that printers demanded were way beyond what self-publishers could spend. We are thankful that POD technology made it possible for us to self-publish and Amazon to re-invent book selling. Note: The economic travails of the 70s and early 80s also sent US publishers as a rule to Asian printers, where labor costs were much less. This spelled the deaths of American companies and industries with long-standing stakes in book printing and binding. That’s another story.

I am impressed with how creatively Amazon configured the price increase. Lowering the commission rate for books priced below USD 9.99 is definitely a price increase for authors with books below that price level, but Amazon figured out how to give us a choice. When I received the first notice of the change, I dropped everything, logged into KDP, and raised the prices for all my books priced that were below USD 9.99 to that level. By acting fast, I was able to avoid losing any sales and avoided the lower royalty rate ahead.

When I raised my prices, I did not notice initially that there are new thresholds for most of Amazon’s non-US markets as well. So, I had to make a second pass and re-set prices for the UK, Canada, etc.

Take a quick look at this analysis of the costs of printing and binding a 200-page paperback book. Thirty-five to 45% of the total cost of printing and binding can come from paper and ink. A five ot ten percent increase (tariff or otherwise) will play havoc with the bottom line.

Cost ComponentTypical % of Total Cost
Paper25–30%
Ink10–15%
Labor15–20%
Binding10–15%
Overhead10–15%
Other (margin, packaging, etc.)10–15%

But wait, there’s more.

It seems pretty transparent that Amazon bundled a cost reduction with their price increase to soften the blow.
we are reducing color printing costs for paperbacks in some marketplaces to help authors adopt color printing

Color printing generally requires better-grade (thicker, denser) paper than black-and-white printing to avoid “bleed-through” and ink dispersion effects that degrade image quality. This costs more. So, by lowering the cost, Amazon has either found a workaround or is able to handle reduced margins for color printing as compared with the margin increases that they will realize from the price increases described above.

Either way, I will re-think whether I have books that will benefit from color printing. Note that the cost reductions impact both standard and premium color jobs. At Touchwood Press, we’ll be looking at the viability of creating color versions of our 50 Fun Facts print books to match the color we can include in the eBook versions of those books for readers using phones or tablets.

The Times, They Never Stop Changing

It has long held true in publishing that 20% of the titles make for 80% of the profits. Whether the typical numbers are more like 40/60 or 10/90, the principle is the same. In any speculative business such as book publishing (or movies or music or gold mining), the best-sellers carry the rest of the list to profitability and sustainability. But if Lora Kelly, a writer for The Atlantic, is right, even this economic pillar of the publishing business is changing. See Taylor Swift Is a Perfect Example of How Publishing Is Changing for the story.

This may be very good news for other self-publishing authors like Ms. Swift. I’ve always thought that the best way for a self-publishing author to get a shot with an established, aka traditional, publisher is to wait for them to come to you. For years now, savvy acquisition editors have been training their sights on Amazon and other platforms to get a bead on the next best sellers. A single shot to an aspirational writer has sometimes landed a new super-star author. What are the odds? Better than a total shot in the dark, apparently.

So, be ready for that e-mail or letter from an editor at a big-name publisher. Know your rights, and your copyrights. Be prepared to sell some, but not necessarily all, your rights to the first big-game hunter who has their sights on you. In the meantime, dream big, and get back to writing your sequel!

Should I publish my blog before or after I publish my book?

Publishing a blog any time can work to your benefit. If you create your blog as you’re writing the book, you have an online notebook where you can try out and refine content. Blog posts can be held as drafts indefinitely, so you don’t need to publish them until you’re ready. When you do, you can promote them in a variety of ways and generate comments that may help you think about possible improvements.

After your book is published, your blog is a great promotional tool and a way to interact with readers.
