Kids coloring books require 30 pages, sell for $5.99, and compete with Disney. Adult coloring books need 70+ pages, command $9.99, and benefit from Amazon's higher 60% royalty rate at that price point. Neither is "better"—but one is better for YOU. Here's the complete comparison to choose your KDP coloring book niche.
📈 2026 Market Update
The coloring book market continues to evolve in 2026. Here are the key trends shaping the kids vs adult decision:
- "Bold and Easy" style dominance: The biggest trend in 2025-2026 is the "Bold and Easy" coloring book style—large, simple outlines that are easy to color. This blurs the line between kids and adult books and has created a massive new market segment appealing to beginners, seniors, and casual colorists.
- 8.5x8.5 square format emerging for kids: Square-format coloring books (8.5" x 8.5") are gaining traction in the kids market. 64% of bestselling kids coloring books now use this format. It feels more "activity book" than "textbook" and is easier for small hands to manage.
- AI-generated content flooding the market: Competition has increased across both niches as AI tools make creation easier. Differentiation through niche specificity and quality is more important than ever.
- Post-royalty-change landscape: Since the June 2025 royalty change (50% under $9.99, 60% at $9.99+), the profit advantage of adult books has widened significantly, making the $9.99 price threshold a critical strategic decision.

Goal: $1,000/month passive income
Kids books approach (50% royalty at $6.99):
- $2.17 profit per book
- Need 461 sales/month
- Strategy: Publish 20 books, each selling ~23 copies/month
Adult books approach (60% royalty at $9.99):
- $4.30 profit per book

Marketing Strategies
Kids Coloring Books
- Amazon keywords: Focus on age ranges + specific topics ("dinosaur coloring book ages 4-8")
- Pinterest: Less effective (parents don't heavily engage with coloring content)
- Facebook groups: Parenting groups, homeschool communities (be subtle, provide value first)
- Bundles: Create themed sets (3-pack dinosaur books) for higher AOV
- Reviews crucial: Parents read reviews heavily before purchasing for kids
Adult Coloring Books
- Amazon keywords: Stress relief, mindfulness, specific themes ("nurse coloring book")
- Pinterest: HIGHLY effective—create boards with completed pages, gift guides
- Instagram: #adultcoloring community is massive, share WIP pages
- Gift angle: Market as self-care gifts, white elephant presents, unique birthday gifts
- Seasonal spikes: Leverage New Year (stress relief) and Q4 (gifts) with targeted ads

- You have limited design skills (simple designs easier to create)
- You can identify hyper-specific niches (construction equipment, specific animals)

- You're comfortable with longer creation time for premium products
The "Bold and Easy" Middle Ground (2026 Strategy)
In 2026, the "Bold and Easy" coloring book style has created a powerful third option. These books feature large, simple outlines that appeal to both beginners and adults who want a relaxing experience without intricate detail:
- Target audience: Beginners, seniors, casual colorists, and people with limited dexterity
- Design style: Bold outlines (3-4px), simple compositions, recognizable subjects
- Pricing advantage: Can command $8.99-$9.99 (adult pricing) with simpler designs (kids-level effort)
- Competition: Growing fast but sub-niches remain underserved (Bold and Easy flowers, Bold and Easy animals, Bold and Easy landscapes)
- Creation time: 4-6 hours per book—faster than traditional adult books
The Hybrid Approach
Many successful KDP publishers do BOTH:
- Start with kids books: Build portfolio quickly (10-15 books in 2-3 months)
- Reinvest profits into adult books: Use earnings to create higher-quality adult books
- Diversify income: Kids books = steady small income, adult books = fewer but larger sales
- Add Bold and Easy books: Capture the trending middle market with faster production time
- Cross-promote: Bundle related kids + adult books for family gifts

If you're brand new to KDP: Start with kids coloring books. Lower barrier, faster learning curve, quicker feedback loop. Publish 5-10 books in different niches to learn what sells.
If you have design skills or budget: Focus on adult coloring books. Higher margins, less saturated (in specific niches), and premium pricing opportunities.
Long-term strategy: Build portfolio of both. Use kids books for consistent base income, adult books for higher-value sales. Diversification wins.
