Reflowable text and fixed images want opposite things.

Straight-text books are close to a solved problem. Chapters follow chapters, paragraphs follow paragraphs, and a good template handles nearly all of it. Add photographs, tables, sidebars, or exercises and every one of those assumptions breaks at once.

Here is why complex books are genuinely harder, how to decide which approach yours needs, and what it costs to do properly.

The core conflict

A reflowable ebook lets the reader control type size, which means text moves. An image has fixed proportions and a caption that must stay with it. Those two facts are in direct tension, and everything difficult about illustrated ebooks follows from it.

Set the type larger and the paragraph that referred to the diagram above is now three screens away from it. A table wide enough to be meaningful will not fit a phone at any readable size. A sidebar designed to sit beside the main text has nowhere to sit when the column is 320 pixels wide.

Print does not have this problem, because everything is fixed. Which is why many complex books are straightforward in print and genuinely awkward as ebooks, and why the two versions sometimes need different editorial decisions rather than just different files.

That last point deserves emphasis, because it is where authors lose the most time. The instinct is to treat the ebook as a conversion job: same content, different container. For an illustrated book it is closer to a second edition. Sentences that say "as shown opposite" have to be rewritten. Exercises that assume a page to write on need a different instruction. A two-page spread that works as a single visual has to become something else entirely. None of that is formatting work in the mechanical sense, and all of it has to be decided by whoever wrote the book.

Reflowable or fixed layout

There are two ebook models, and choosing the wrong one is the most expensive mistake available here.

Fixed layout sounds appealing because it preserves your design exactly. The costs are real: readers cannot enlarge the text, phones show a whole page at once at a size nobody can read, accessibility suffers badly, and not every retailer supports it equally.

The deciding question is whether the position of the image relative to the text is part of the meaning. In a children's picture book, the illustration and the sentence are one unit and fixed layout is correct. In a business book with charts, the chart supports the argument but does not need to sit at a precise point, and reflowable serves readers far better.

How to handle each difficult element

Most complex books are reflowable with a handful of awkward elements rather than genuinely fixed-layout. Each element has a sensible approach.

The pattern across all six is the same: stop trying to preserve a print layout inside a reflowable format, and instead decide what each element is for and rebuild it in a way the format supports.

Image preparation

Complex books live or die on their image files, and this is where most of the avoidable rework originates.

• Supply originals, not images pasted into a document. Pasting downsamples them, usually to screen resolution, and the original quality cannot be recovered afterwards.
• Print needs 300 DPI at final printed size and CMYK. Screen needs RGB at a sensible pixel dimension. These are different exports of the same source.
• Line art and photographs want different treatment. Diagrams stay crisp as vectors or high-resolution PNGs; photographs are better as JPEGs.
• Every image needs alt text, both for accessibility and because some retailers check.
• Name files systematically, matching a figure list. Chapter, figure number, description. This alone saves hours on a book with sixty images.
• Confirm you have the rights. Every image, including anything found online, including anything a colleague supplied.

That last point causes more late problems than any technical issue. Rights need to be settled before layout, because replacing an image after the interior is built means redoing the pagination around it.

Print is where complex books work best

It is worth saying plainly: if your book is genuinely image-led, print is the format where it will look the way you intended, and the ebook is the compromise rather than the other way round.

Print gives you fixed pages, facing-page spreads, exact image placement, and full-bleed artwork that actually bleeds. A cookbook, an art book, or a photography collection is a print object with an ebook edition, not the reverse. That has a practical consequence for where you spend attention: perfect the print interior first, then decide how much fidelity the ebook edition genuinely needs.

It also affects trim size. Image-led books usually want a larger trim, which means fewer pages and a thinner spine but a higher print cost per copy and higher postage. Those trade-offs are worth settling before layout begins, because changing trim size afterwards means rebuilding every page.

Getting the manuscript ready

Complex layout goes far more smoothly when the source material arrives organised. This is the part authors can do themselves, and it measurably shortens the work.

1. Number every figure and refer to it by number in the text, never by position.
2. Supply a figure list matching filenames to numbers, captions, and credit lines.
3. Keep images in a separate folder at full resolution, alongside the manuscript rather than inside it.
4. Mark intended placement in the text with a clear inline note, so the layout has a starting point.
5. Write captions as final text, not placeholders. Captions written during layout tend to read as afterthoughts.
6. Confirm rights and credit lines for every image before layout starts.
7. Decide what happens to each element in the ebook, particularly tables and exercises, rather than leaving it to be resolved mid-build.

The last item is the one that most often turns a smooth project into a slow one. Deciding upfront that the three widest tables will become images with text alternatives, or that the workbook exercises will be a downloadable PDF, removes a whole category of mid-build questions.

Why it costs more

Straight-text formatting is largely a matter of applying a well-built template and checking the result. The work scales with length but not with much else.

Complex formatting does not work that way. Every image placement is a decision. Every table needs individual treatment. Every page has to be checked for a figure stranded away from its reference, an awkward break, or a caption orphaned onto the next page. A 200-page illustrated book can involve more individual decisions than a 400-page novel.

That is what the $2,100 premium tier reflects: not a surcharge, but genuinely different work. For comparison, standard ebook and print formatting is $450 or $690 depending on whether you need one format or both.

Deciding which tier you need

A rough test. If your book is text with a handful of images that could sit anywhere in their chapter, the standard tier handles it. If images, tables, or exercises are structural to how the book works, it is premium.

Books that are usually premium: cookbooks, children's picture books, workbooks, technical manuals with many figures, photography books, and anything with sustained sidebars or multi-column layout. Books that usually are not: novels, memoirs, and business books with a dozen simple charts.

If you are genuinely unsure, that uncertainty is worth a conversation rather than a guess, because paying for the wrong tier means doing the work twice. You can book a free call and describe the book, or read the EPUB and print PDF comparison first if the underlying formats are still unclear.

Our formatting service handles all three tiers, with files built to upload to Kindle, Apple Books, Barnes & Noble, Google Books, and IngramSpark, in 7 days from a final manuscript. Barker Publishing House has been formatting complex books since 2018, and you keep 100 percent of your rights and royalties.
