Yeah… this one trips people up hard.
You finish your book, export it, upload it… and suddenly:
- Text is cut off
- Images shift or look blurry
- Nothing resizes on phones
- KDP throws warnings you don’t understand
You start thinking you broke something.
You didn’t. You just picked (or inherited) the wrong format.
Let’s get your head straight first. Everything else gets easier after that.
The One Thing Most People Don’t Understand (And It Breaks Everything)
Here it is, plain and simple:
A fixed layout book does NOT adapt to the screen.
It’s basically a PDF pretending to be an ebook.
Think of it like printing a page and gluing it to every device:
- Phone? Same page, just shrunk
- Tablet? Same page, maybe fits better
- Kindle e-ink? Often terrible experience
That’s the whole game.
So if you expected:
- Text to reflow
- Font size to adjust
- Layout to shift for mobile
…you’re already in the wrong format.
When Fixed Layout Is Actually the Right Choice
Don’t use fixed layout because it “looks nice.” Use it when you have no choice.
You need it if your book depends on visual positioning:
- Children’s picture books
- Comics / graphic novels
- Cookbooks with tight image-text pairing
- Textbooks with diagrams and callouts
- Art / photography books
- Anything where moving text breaks meaning
If your book is just:
- Novel
- Memoir
- Simple nonfiction
Then fixed layout will hurt your reader experience. Badly.
The #1 Reason Your Fixed Layout Looks Broken
I’ve seen this hundreds of times.
Your page size is wrong from the start.
People design in:
- A4
- Letter (8.5×11)
- Random Canva dimensions
Then export to EPUB fixed layout.
Result?
- Tiny unreadable text on phones
- Weird margins
- Cropped content
What you should be using instead
| Use Case | Recommended Size |
|---|---|
| Most FLL ebooks | 1600 x 2560 px |
| Landscape-heavy books | 2560 x 1600 px |
| Square-ish designs | 2048 x 2048 px |
Pick one. Stick to it from page one.
Don’t “fix it later.” You won’t.
Images Looking Blurry? This Is Why
You exported everything at 72 DPI because “it’s digital.”
That advice ruins fixed layout.
Use high-resolution images from the beginning.
What actually works:
- Minimum: 150 DPI
- Safer: 300 DPI
- Export images at final size (don’t upscale later)
And here’s the kicker most people miss:
Kindle compresses your images. Hard.
So if your original isn’t sharp, it will look worse after upload.
Text Too Small on Mobile (This Is the Real Problem)
Nobody tells you this clearly:
Fixed layout books are NOT mobile-friendly by default.
A page that looks perfect on your laptop?
Unreadable on a 6-inch phone.
What I do to avoid this mess
- Keep font size larger than you think
- Avoid long paragraphs
- Limit text per page
- Test on an actual phone (not just preview tools)
If someone has to zoom every page, they won’t finish your book.
Simple as that.
Fixed Layout EPUB vs PDF — Stop Mixing Them Up
This confusion wastes days.
Here’s the difference that matters:
| Format | What It Really Is | Where It Works |
|---|---|---|
| Static document | Print, downloads | |
| Fixed Layout EPUB | Controlled ebook | Kindle, Apple Books |
| Reflowable EPUB | Flexible text | Most ebooks |
PDF is not an ebook format. It’s a document.
Uploading a PDF to KDP and hoping for a good result?
That’s where things go sideways.
The “Why Is KDP Rejecting My File?” Moment
You’ll see errors like:
- “Text not selectable”
- “Accessibility issues”
- “Navigation missing”
Here’s what’s happening under the hood:
Your file is just images without proper structure.
Fixed layout still needs:
- Table of contents (nav file)
- Proper HTML structure
- Defined reading order
Even if everything looks visual, the backend still matters.
The Simple Fix Most People Overlook
This is the part almost everyone skips:
Build your fixed layout using EPUB tools, not design tools alone.
Design tools (like Canva, InDesign) are fine for layout…
…but exporting correctly is the real job.
What actually works in real projects
- Adobe InDesign → Export as Fixed Layout EPUB (with correct settings)
- Or build using EPUB editors (for full control)
And always:
- Open the EPUB after export
- Check every page
- Click through navigation
Don’t trust the export blindly.
When Things Still Look Wrong (The Weird Edge Cases)
This is where experience kicks in.
Random layout shifts?
- Caused by unsupported fonts
- Fix: Embed fonts properly or use standard ones
Pages cut off on Kindle but fine elsewhere?
- Kindle previewer lying (yes, it happens)
- Fix: Test on real device or multiple previews
Text not selectable?
- You flattened everything into images
- Fix: Keep text as text where possible
File size too large?
- Oversized images
- Fix: Compress without killing clarity (balance matters)
The “Nuclear Option” When Nothing Works
If you’ve tried everything and the EPUB keeps breaking:
Rebuild a few pages from scratch. Don’t patch the broken file.
I’ve seen people waste 3 days fixing something that took 20 minutes to redo clean.
Start fresh with:
- Correct page size
- Clean layout
- Proper export settings
Then scale that structure across the book.
What I Wish Every New Author Knew From Day One
This would save you a lot of pain:
- Fixed layout is not beginner-friendly
- It trades flexibility for control
- Every mistake shows up immediately
- Testing matters more than design
And most important:
If your book doesn’t absolutely require fixed layout… don’t use it.
Reflowable EPUB exists for a reason.
Quick Reality Check Before You Continue
Ask yourself:
- Does my content break if layout changes?
- Am I okay with limited mobile readability?
- Am I ready to test across devices?
If you hesitate on any of these…
You’re probably forcing fixed layout where it doesn’t belong.
You’re not stuck. You just needed to understand the rules of the game.
Now you do.
