How to Format a Children’s Book for IngramSpark: Step-by-Step Guide for Authors

Why Children’s Book Formatting Matters

Children’s books require precise formatting because they combine text, illustrations, and page flow in a way that must print perfectly. IngramSpark has strict technical guidelines for picture books and early readers, and following them ensures your book appears professional, vibrant, and error-free.
This guide walks you through each step of the process, from trim size to exporting your final print-ready file.

Understanding IngramSpark’s Requirements for Children’s Books

Children’s books often include full-bleed artwork, colorful illustrations, and specific layout needs. To avoid upload issues, you must prepare your file correctly before export.

Key Requirements

• PDF/X-1a:2001 format

• CMYK color mode for all illustrations

• 300 DPI image resolution

• Correct trim size, margins, and bleed

• Single pages (not spreads) unless creating a fixed-layout book

• Page count must match IngramSpark’s specifications

Choosing the Right Trim Size for a Children’s Book

Trim size is one of the most important decisions when designing a kids’ book. IngramSpark supports multiple sizes, but some are more popular and industry-friendly.

Best Trim Sizes for Children's Books

• 8.5" x 8.5" – the most common square format

• 7" x 10" – ideal for illustrated stories

• 8" x 10" – great for full-bleed picture books

• 6" x 9" – good for early readers with more text

Choose a trim size that complements your illustrations and creates a visually pleasing reading experience.

Setting Up Bleed, Margins, and Safe Zones

Incorrect bleed and margin setup is the #1 cause of IngramSpark rejection for children’s books.

Bleed

Use bleed on pages where artwork touches the edge.
Standard bleed size: 0.125" (3 mm) on all sides.

Margins

Margins should be wide enough to protect text from the trimming blade.
Recommended margins: 0.5" to 0.75"

Safe Zone

Keep all text and essential details at least 0.25" inside the margin.

Preparing Your Illustrations for Print

Children’s book illustrations must be high quality so they look crisp and vibrant once printed.

Illustration Requirements

• Export artwork at 300 DPI

• Convert colors to CMYK

• Avoid transparency effects

• Maintain consistent style and color palette

• Use Illustrator, Photoshop, Procreate, or Clip Studio Paint for best results

If your Illustrator or Procreate file uses RGB, convert to CMYK before exporting — otherwise colors may print dull or inaccurate.

Designing the Page Layout

A children’s book layout should be visually balanced with clear storytelling flow.

Page Layout Tips

• Use large, readable fonts (16–24 pt)

• Combine text and illustrations harmoniously

• Keep text away from character faces or busy backgrounds

• Use consistent spacing across all pages

• Follow a predictable rhythm: left-page setup, right-page action

For early readers, keep text in a simple location on each page. For picture books, maintain strong visual flow between spreads.

Should You Use Single Pages or Spreads?

IngramSpark requires single-page PDFs, but you can still design your book in spreads for easier creativity.

Best Practice

• Design in spreads (especially for full-bleed books)

• Export as single pages with bleed included

This keeps your design visually cohesive while meeting IngramSpark’s technical rules.

Adding Page Numbers (When Needed)

Most picture books for ages 3–6 do not include page numbers.
Early readers (ages 6–8) usually do.

Where to Place Page Numbers

• Keep them outside the artwork

• Avoid placing numbers near the gutter

• Use simple, readable fonts

If you’re unsure, check bestselling children’s books in your target age range.

Exporting a Print-Ready PDF for IngramSpark

Before uploading, your PDF must meet strict requirements.

Export Checklist

• Export as PDF/X-1a:2001

• Ensure all fonts are embedded

• Check that all images are 300 DPI CMYK

• Flatten any transparency

• Include bleed in the export settings

• Make sure the page count is correct

Always open your PDF and scan every page before submission.

Common Formatting Mistakes to Avoid

Avoiding simple errors can save you time and revision fees.

Common Problems

• Artwork created in RGB instead of CMYK

• Missing bleed on full-bleed pages

• Text placed too close to edges

• Low-resolution illustrations

• Incorrect trim size setup

• Misaligned spreads

Double-check these areas before exporting.
