IngramSpark Formatting Guide 2026: Perfect Your Book Layout for Print & eBook

Why Proper Formatting Matters on IngramSpark

Publishing on IngramSpark gives authors access to global distribution, bookstore visibility, and professional-grade printing. But to take full advantage of these benefits, your interior formatting must meet IngramSpark’s technical standards. Proper formatting helps you avoid upload errors, printing issues, unexpected charges, and reader complaints.
This guide explains everything you need to format your book correctly in 2025 — whether it’s a children’s book, a novel, or a workbook.

Understanding IngramSpark’s Formatting Requirements

Before creating your file, it’s important to understand the core specifications IngramSpark accepts for both print and eBook formats.

Print Book Requirements

• PDF/X-1a:2001 format

• Fonts must be embedded

• CMYK color profile for illustrated books

• Correct trim size, margins, and bleed

• Single-page layout (not spreads) unless using a picture book with full bleed

• 300 DPI minimum for images

eBook Requirements

• EPUB file format

• Reflowable EPUB for text-heavy books

• Fixed-layout EPUB for illustrated or children’s books

• High-resolution images (at least 300 DPI)

Choosing the Right Trim Size

Your trim size determines how your book looks and how much it costs to print. IngramSpark supports many sizes, but here are the most common.

Popular Trim Sizes for Different Book Types

• Children’s books: 8.5" x 8.5", 7" x 10"

• Novels: 5" x 8", 5.5" x 8.5", 6" x 9"

• Workbooks: 8.5" x 11"

Choose a trim size that matches industry expectations so your book feels professional.

Understanding Bleed, Margins, and Safe Zones

Incorrect margins and bleed settings are the #1 reason authors face IngramSpark rejections.

Bleed

Use bleed if any artwork or background color touches the edge of the page.
Common bleed size: 0.125" (3 mm) on all sides.

Margins

Margins protect your text from being cut off.
Recommended margins: 0.5" to 0.75"

Safe Zone

Keep essential elements away from the edges.
Place all text at least 0.25" inside your margin.
