Why Kidillus
Why Authors Choose Us
✅
First-Upload Guarantee
KDP or IngramSpark rejects our file due to a technical error? We fix it free. No argument, no extra invoice — your upload passes or we keep working.
📐
Adobe InDesign — Not Word
We use industry-standard software. Word templates break on export. InDesign anchors every element precisely — your text won't shift, your images won't move.
🎨
CMYK — Not RGB
Uploading RGB files causes unexpected colour shifts in print. Every file we deliver is in CMYK mode — what you proof is exactly what you print.

FAQ
Frequently Asked Questions — Children's Book / KDP
The most popular KDP trim sizes for picture books are 8.5"×8.5" (square — most popular for ages 3–8), 8"×10" (portrait — good for activity and educational books), and 11"×8.5" (landscape — good for panoramic double-page spreads). We will recommend the best trim size for your story format during our <a href='/price-quote' style='color:var(--fmt-accent);text-decoration:underline;'>quoting process</a>.
Full-bleed means your illustrations extend 3mm beyond the trim line on all four edges. When the book is trimmed at the printer, no white border appears. Without correct bleed, KDP will either reject your file or your printed book will have unwanted white borders. Read our <a href='/learn/book-trim-sizes-bleed-margins' style='color:var(--fmt-accent);text-decoration:underline;'>bleed and margins guide</a> to learn more. We set bleed correctly on every page.
Yes — our Print + eBook package includes both the KDP print PDF and a fixed-layout ePub for Kindle. The fixed-layout ePub locks your illustrations and text in place on every Kindle and tablet screen. This is the required format for picture books — reflowable ePubs do not work for illustrated children's books.
A standard 32-page picture book is formatted and delivered within 3–5 business days. Rush delivery (48 hours) is available at an additional fee. Larger page counts and coloring books may take 5–7 business days.
Yes. Every file is built to KDP's current specifications. In the rare event of a technical rejection caused by our formatting, we fix it at no additional cost — no argument.
Send your final illustration files (JPG/PNG/TIFF at 300 DPI minimum) and text manuscript (Word/Google Doc). If your illustrator has placed text on the artwork already, send the layered PSD or TIFF files. We confirm receipt within 4 business hours.
Pricing starts from $80 for this service. Exact cost depends on page count and whether you need print-only, print + ePub, or the full platform package. Get a free itemised quote at kidillus.com/price-quote.
About Our Children's Book KDP Formatting Service
Kidillus provides specialist children's book kdp formatting for independent authors self-publishing children's books. Our team works exclusively on illustrated books — picture books, board books, activity books, and coloring books — where the technical formatting requirements are significantly more complex than a standard novel or memoir.
Every file we produce meets the current specifications for Amazon KDP and IngramSpark. We use Adobe InDesign for all formatting work — not Word, not Canva, not automated tools — because only professional software guarantees that every element stays anchored correctly through the export and upload process.
