Larger type, generous leading, illustrated chapter openers, the age-band design conventions readers (and parents) expect. For middle-grade readers aged 7-12 — chapter books, early readers, illustrated middle grade.

Run the KDP Readiness Score →The format choice that matters most. We can deviate if your project needs it — but here's the working benchmark.
Acceptable alternatives: 5×8 in or 6×9 in · all are KDP-approved trim sizes
5.5×8.5 is the trad middle-grade trim (think Roald Dahl, Wimpy Kid, Tom Gates). It gives a generous body-text size (12-13pt) without the book feeling unwieldy in a 9-year-old's hands. Pages turn fast — which is half the experience at this age.
Chapter books with illustrations get image pre-flight on every plate — 300 DPI, sRGB, transparent-PNG safe.
The six things that make children's chapter book formatting different from generic novel formatting.
12-13pt body text, 1.6 leading, 60-65 character line length. Type sized for 7-12 year-old readers, not adult novels shrunk down.
Half-page or full-page illustration at every chapter opening. Treated as 300 DPI plates, registered to the chapter heading so they feel composed, not pasted.
Smaller decorative illustrations between paragraphs. Anchored semantically so they survive Kindle reflow without orphaning the caption.
Generous white space, short paragraphs, dialogue on its own line. Layout that supports reluctant readers without infantilising the book.
If your book uses handwritten-style fonts, doodles, or kid-narrator visual gags (Wimpy Kid style), we render them at print-safe DPI and EPUB-safe sizes.
About-the-author page that speaks to parents and grandparents. Reading-age guidance. Discussion questions if relevant. "What to read next" page.
Whatever the book type, this is what every order includes.
KDP-compliant margins, mirrored gutters scaled to your page count, 0.125-inch bleed where needed, embedded fonts, 300 DPI image pre-flight, semantic page-break logic.
Optimised for every Kindle device including phone reading. Clean chapter recognition, working drop caps, scene-break ornaments, properly-linked TOC, semantic ordered/unordered lists.
Spine width auto-calculated from your final page count. Cover supplied to KDP-template spec for paperback, hardback or both. Full-bleed art tested against KDP's print profile.
Side-by-side viewer to comment on specific pages. Most books need none; complex non-fiction sometimes needs both. Additional rounds £19 each.
If KDP rejects your file for a formatting reason, we fix it free. We've never had a rejection — but the guarantee is the principle.
