What Kind of Paper Should We Use for Children’s Books?

Choosing the right paper for a children’s book is one of the most important decisions you’ll make in the entire printing process.

Pick the wrong paper? Your beautiful illustrations look washed out. The pages bleed through. Or worse — a toddler rips the book apart in 30 seconds flat.

Pick the right paper? Your book looks (and feels) like it belongs on the shelf next to the big-name publishers.

In this guide, I’ll walk you through exactly how to choose the best paper for every type of children’s book — based on our 12+ years of printing over 200 million children’s books for publishers across 30+ countries.

Let’s dive right in.

Paper Types for Children’s Books: A Quick Primer

Before we get into the specific recommendations, let’s make sure we’re on the same page about the paper types you’ll encounter most often.

Art Paper (Coated Paper)

Art paper — also known as coated paper or C2S (coated two sides) — has a smooth, glossy or matte coating on both sides. This coating is what gives printed images that sharp, vibrant look.

It’s the go-to choice for picture-heavy children’s books. And here’s why:

The coating prevents ink from being absorbed too deeply into the paper fibers. So your colors stay punchy and saturated instead of looking dull and muted.

In other words: if your children’s book is packed with colorful illustrations (and most are), art paper is almost always your best bet for the inner pages.

Common weights: 105gsm, 128gsm, 157gsm, 200gsm

Woodfree Paper (Uncoated Paper)

Woodfree paper (also called offset paper or uncoated paper) doesn’t have that surface coating. It has a more natural, slightly rough texture — similar to the paper you’d find in a novel or textbook.

It’s great for text-heavy content. But it’s NOT ideal for vibrant full-color illustrations because the ink gets absorbed unevenly, which makes colors look flatter.

That said, woodfree paper has its place. It works well for activity books, coloring books, and educational workbooks where kids need to write or draw on the pages. (Try writing with a pencil on glossy art paper — it doesn’t work.)

Common weights: 80gsm, 100gsm, 120gsm, 140gsm

Cardboard Paper (Paperboard)

This is the thick, rigid material used for board books and paperback covers. When you see “350gsm + 350gsm” for a board book, that means two sheets of 350gsm cardboard are laminated together to create one ultra-thick page.

The result? Pages that are virtually tear-proof and can survive being chewed on, thrown across the room, and dunked in juice. (Yes, we’ve heard all of these stories from our clients.)

Common weights: 250gsm, 300gsm, 350gsm

Gray Board

Gray board is the rigid cardboard core inside hardcover books. You don’t see it directly — it’s wrapped in printed art paper to create that premium hardcover feel.

Common thicknesses: 1.5mm (1500gsm), 2.0mm, 2.5mm, 3.0mm (3000gsm)

Quick rule of thumb: The thicker the gray board, the more premium (and heavier) the book feels.

What Does “GSM” Actually Mean?

You’ll see “gsm” everywhere in paper specs. It stands for “grams per square meter” — and it’s simply a measure of paper weight (or thickness).

Here’s a quick reference to put it in perspective:

• 80gsm = Standard office copy paper
• 120gsm = Premium letterhead
• 157gsm = A solid children’s book inner page
• 250gsm = Thin cardstock (think business cards)
• 350gsm = Thick cardboard (board book pages)

Higher gsm = thicker, sturdier paper. Simple as that.

But here’s what most people don’t realize: gsm alone doesn’t tell the whole story. Two papers with the same gsm can feel very different depending on whether they’re coated or uncoated. A 157gsm art paper feels smoother and slightly thinner than a 157gsm woodfree paper, even though they weigh the same.

That’s why you always want to request physical paper samples before committing to a large print run. (More on that later.)

5 Key Factors That Determine Your Paper Choice

Before you jump to the recommendation tables, it’s important to understand the factors that should drive your paper decision.

Factor #1: Target Age Group

This is THE most important factor. And here’s why:

Children aged 0–3 put everything in their mouths. They grab, pull, and tear. For this age group, you need the thickest, most durable paper possible — which is why board books (350gsm + 350gsm cardboard) are the industry standard for babies and toddlers.

Children aged 3–6 are gentler but still rough on books. Hardcover books with 157gsm or 200gsm art paper inner pages work well here.

Children aged 6+ can handle standard paperback books. You can go with lighter paper weights (120–157gsm) without worrying about durability as much.

Factor #2: Content Type

Full-color picture books need art paper. Period. The coating ensures that illustrations look their absolute best.

Text-heavy readers and educational books? Woodfree paper works fine — and it’s easier on the eyes for extended reading because there’s no glare from the coating.

Activity books and workbooks where kids write or draw? Woodfree paper is the only real option here because pencils and crayons don’t grip well on coated surfaces.

Factor #3: Page Count

This one matters more than most people think.

If your book has fewer than 32 pages, saddle stitching (staple binding) is a cost-effective option. But if you’re over 32 pages, you’ll generally need perfect binding (paperback) or case binding (hardcover).

Here’s the thing: with saddle stitched books, using paper that’s too thick can cause the book to bulge and not lie flat. We typically recommend keeping inner pages at 157gsm or below for saddle stitched children’s books.

Factor #4: Budget

Let’s be real — budget matters.

Here’s a general cost ranking from most to least expensive binding types:

1. Board book (most expensive — due to thick cardboard pages)
2. Hardcover
3. Paperback (perfect bound)
4. Saddle stitched (least expensive)

Within each binding type, art paper is generally more expensive than woodfree paper. And heavier weights cost more than lighter weights.

Pro tip: If you’re a first-time self-publisher on a tight budget, start with a saddle stitched book using 157gsm art paper. It’s the most affordable way to produce a professional-looking children’s book.

Factor #5: Safety and Environmental Standards

If you’re selling children’s books in the US, EU, or UK, your paper and inks need to meet specific safety standards.

For the EU market, EN 71 (Toy Safety Standard) sets requirements for materials used in products intended for children under 14. For the US market, CPSIA (Consumer Product Safety Improvement Act) requires third-party testing for lead and phthalates.

On the environmental side, more and more publishers are requiring FSC-certified paper (Forest Stewardship Council). FSC certification means the paper comes from responsibly managed forests.

In our experience, about 70% of our European and North American clients now request FSC-certified paper. If you’re planning to sell through major retailers like Amazon, Barnes & Noble, or Waterstones, FSC certification is practically a must-have.

We also exclusively use soy-based inks that comply with ASTM F963 and EN 71-3 safety standards — ensuring the printed materials are non-toxic and safe for young children.

Paper Recommendations by Book Type

Now let’s get into the specific recommendations. These are based on our most popular configurations — the ones that have proven to deliver the best quality-to-cost ratio across thousands of projects.

Hardcover Children’s Book

A hardcover children’s book delivers that premium, library-quality feel. It’s the most popular choice for picture books aimed at ages 3–8.

Part	Recommended Paper	Recommended Weight	Finish
Cover wrap	Art paper (C2S)	157gsm	Glossy or matte lamination
Cover board	Gray board	2.5mm or 3.0mm	—
Endpapers	Woodfree paper	140gsm or 160gsm	—
Endpapers (alternative)	Art paper	157gsm	—
Inner pages	Art paper (C2S)	157gsm	Optional matte or glossy varnish

Why these specs?

The 157gsm art paper for inner pages is our most-recommended weight for hardcover children’s books — and for good reason. It’s thick enough that full-color printing on both sides won’t show through (called “show-through” or “ghosting” in the industry). It also has a satisfying weight when you turn the pages. But it’s not so heavy that a 32-page book becomes uncomfortably thick.

We recommend 2.5mm or 3.0mm gray board for the cover. The 2.5mm option gives you a sturdy, professional feel without adding too much weight — great for books under 8.5 x 8.5 inches. For larger format books (like 11 x 11 inch), go with 3.0mm to prevent the cover from warping over time.

For endpapers, woodfree paper at 140–160gsm is the standard. But here’s a tip: if your endpapers feature printed illustrations (which is a fantastic design touch, by the way), switch to 157gsm art paper for better color reproduction.

A common mistake we see: Some clients choose 128gsm art paper for inner pages to save on cost. The difference in per-unit cost is minimal (usually less than $0.05 per book), but the difference in quality is noticeable. At 128gsm, you’ll start seeing slight ghosting on pages with heavy ink coverage. In our experience, it’s simply not worth the savings.

Paperback Children’s Book

Paperback binding is a great middle-ground option. You get a professional-looking book at a lower cost than hardcover.

Part	Recommended Paper	Recommended Weight	Finish
Cover	Cardboard paper (C1S)	250gsm or 300gsm	Glossy or matte lamination
Inner pages	Art paper (C2S)	128gsm or 157gsm	—
Inner pages (text-heavy)	Woodfree paper	100gsm or 120gsm	—

Why these specs?

For the cover, 250gsm cardboard with lamination is the minimum you should go with. Lamination isn’t optional here — without it, the cover will scuff, curl, and look worn out within weeks. Matte lamination gives a modern, sophisticated look. Glossy lamination makes colors pop and is easier to wipe clean (a real selling point when the target audience has sticky fingers).

For illustration-heavy inner pages, 157gsm art paper is ideal. But if your page count is high (48+ pages), you might want to consider 128gsm art paper to keep the book from getting too bulky. At this weight, show-through is minimal as long as you don’t have solid dark backgrounds printed on both sides.

If your book is more text-focused (like an early chapter book for ages 6–8), 100gsm or 120gsm woodfree paper gives a comfortable reading experience without the glossy glare that can cause eye strain during extended reading.

Pro tip from the production floor: We always recommend paperback covers at 300gsm (rather than 250gsm) if your page count exceeds 40 pages. A thicker cover provides better structural support and prevents that “floppy” feeling that makes a book look cheap.

Saddle Stitched Children’s Book

Saddle stitching (staple binding) is the most budget-friendly option. It’s perfect for thin books, activity booklets, coloring books, and promotional children’s publications.

Part	Recommended Paper	Recommended Weight	Finish
Cover	Art paper (C2S)	200gsm or 250gsm	Glossy or matte lamination
Inner pages	Art paper (C2S)	128gsm or 157gsm	—
Inner pages (activity books)	Woodfree paper	100gsm or 120gsm	—

Why these specs?

Saddle stitched books have a key structural limitation: the inner pages fold around the staples. If the paper is too thick or there are too many pages, the book will bulge at the spine and the outer pages won’t align properly with the inner pages (this is called “creep”).

That’s why we recommend a maximum of 32 inner pages (or 64 page sides) for saddle stitched children’s books with 157gsm paper. If you need more pages, either drop to 128gsm or switch to perfect binding.

For the cover, 200gsm art paper with lamination is sufficient for most saddle stitched books. No need to go heavier — since the book is thin, a very rigid cover would actually make it harder to open and read.

Important note on activity books: If the book includes pages where children need to write, draw, or use stickers, make sure to use uncoated woodfree paper for those pages. We’ve had clients who used art paper for their activity books only to discover that crayon marks smudge and pencil doesn’t write smoothly on the coated surface. It’s a frustrating (and expensive) lesson to learn after printing 5,000 copies.

Board Book

Board books are designed for the youngest readers (ages 0–3). Every page is thick, rigid, and virtually indestructible.

Part	Recommended Paper	Recommended Weight	Finish
Cover (hardcover style)	Art paper + gray board	157gsm + 2.5mm or 3.0mm gray board	Glossy or matte lamination
Cover (paperboard style)	Cardboard paper	350gsm + 350gsm (laminated together)	Glossy or matte lamination
Inner pages	Cardboard paper	350gsm + 350gsm (laminated together)	Glossy or matte lamination

Why these specs?

Board book pages are made by laminating two sheets of 350gsm cardboard together, with printed art paper on one or both sides. This creates pages that are roughly 1.5–2mm thick — thick enough that a toddler can’t bend, fold, or tear them.

The lamination on board books serves double duty. It protects the printed surface from drool, food, and sticky fingers. And it also adds structural strength to each page. We recommend glossy lamination for board books because it’s easier to wipe clean. (Parents will thank you.)

For the cover, you have two options. The hardcover style (art paper wrapped around gray board) gives a premium look — similar to a regular hardcover book but with thick board pages inside. The paperboard style (350gsm + 350gsm, same as inner pages) is more common and more cost-effective.

Safety note: All board book pages should have rounded corners to prevent paper cuts and injuries. This is a standard production step, but it’s worth confirming with your printer. In many markets, rounded corners on board books aren’t just a nice-to-have — they’re required to comply with EN 71 toy safety standards.

Common Paper Mistakes (And How to Avoid Them)

Over the past decade, we’ve seen the same paper-related mistakes come up again and again. Here are the most common ones — so you can avoid them:

Mistake #1: Choosing Paper Based on Price Alone

We get it. Budget is important. But we’ve had clients switch from 157gsm art paper to 105gsm to save money, only to reject the entire print run because the pages felt flimsy and showed through.

The cost difference between 128gsm and 157gsm art paper is typically just $0.02–$0.05 per book (depending on page count and print run). For a book you’ll sell for $10–$15, that’s a negligible savings that can significantly impact perceived quality.

Mistake #2: Using Art Paper for Activity or Coloring Books

As I mentioned earlier, coated art paper doesn’t play well with crayons, colored pencils, or markers. The smooth surface causes smudging and prevents colors from adhering properly. Always use uncoated woodfree paper for pages that kids will write or draw on.

Mistake #3: Skipping Lamination on the Cover

An unlaminated cover will show fingerprints, scuff marks, and scratches almost immediately. Children’s books take a beating. Lamination adds less than $0.03 per book but dramatically extends the book’s lifespan and shelf appeal.

Mistake #4: Using the Wrong Gray Board Thickness

If the gray board on a hardcover is too thin (like 1.5mm), the cover can warp — especially in humid climates. We’ve seen this happen with books shipped to Southeast Asia and coastal regions. Stick with 2.5mm minimum for standard sizes and 3.0mm for larger format books.

Mistake #5: Not Accounting for Paper Grain Direction

Paper has a “grain direction” — the direction in which the fibers are aligned. For books, you want the grain running parallel to the spine. If the grain runs perpendicular, pages will resist turning, the book won’t lie flat, and the binding can weaken over time. This is a production detail your printer should handle, but it’s worth asking about.

Mistake #6: Ignoring Show-Through When Using Light Paper

Show-through (where printing from one side is visible on the other) is a real issue with papers below 120gsm, especially with dark or saturated colors. If budget forces you to use a lighter paper, consider designing your inner pages with lighter backgrounds or wider margins near the spine.

How to Choose the Right Paper: A Simple Decision Framework

Still not sure which paper to pick? Walk through these questions:

Step 1: What’s the target age of your readers?

• Ages 0–3 → Board book (350gsm + 350gsm cardboard inner pages)
• Ages 3–6 → Hardcover or paperback (157gsm art paper inner pages)
• Ages 6+ → Paperback or saddle stitched (120–157gsm art paper or woodfree paper)

Step 2: What kind of content is in the book?

• Full-color picture book → Art paper (for best color reproduction)
• Text-heavy reader → Woodfree paper (for comfortable reading without glare)
• Activity / coloring book → Woodfree paper (for writing and drawing)

Step 3: How many inner pages do you have?

• Under 32 pages → Saddle stitched or hardcover
• 32–64 pages → Paperback or hardcover
• Over 64 pages → Paperback (consider 128gsm to manage thickness)

Step 4: What’s your budget per unit?

• Under $2 → Saddle stitched with 128–157gsm art paper
• $2–$5 → Paperback with 157gsm art paper
• $5–$8 → Hardcover with 157gsm art paper
• $8+ → Board book or premium hardcover with special finishes

Step 5: Do you need any special certifications?

• Selling in EU → Ensure EN 71 compliance and FSC certification
• Selling in US → Ensure CPSIA compliance
• Selling through major retailers → FSC certification strongly recommended

Glossy vs. Matte Lamination: Which Should You Choose?

This is one of the questions we get asked the most. Here’s a quick breakdown:

Glossy lamination enhances color vibrancy, makes images “pop,” and is easier to wipe clean. It’s the most popular choice for children’s picture books and board books.

Matte lamination gives a softer, more sophisticated look. Colors appear slightly muted compared to glossy, but the texture feels premium and there’s no glare under lights. It’s increasingly popular for higher-end children’s books and is often chosen by indie publishers who want a distinctive aesthetic.

Soft-touch (velvet) lamination is a premium option that gives the cover a velvety texture. It looks and feels incredible — but it does show fingerprints easily and costs about 15–20% more than standard lamination. Best used for gift editions and premium board books.

Our recommendation for most children’s books? Go with glossy lamination for the cover if your book has vibrant illustrations. Choose matte if you want a modern, understated look. And consider soft-touch only for premium products where the tactile experience is part of the selling point.

Before You Print: Always Request Paper Samples

This is the single best piece of advice I can give you:

Never approve a large print run without first seeing and touching physical paper samples.

Paper specs on a screen tell you the weight and coating type. But they can’t tell you how the paper feels between your fingers. They can’t show you how your specific illustrations will look when printed. And they can’t reveal subtle differences in whiteness, opacity, and surface texture.

Any reputable printer will send you a sample kit with different paper options at no extra cost. At GoBook Printing, we provide free paper sample kits and can even produce a single printed proof copy so you can see exactly what the final product will look like before committing to a full run.

Request your free paper sample kit here — we’ll get it shipped to you within 48 hours.

Wrapping It Up

Choosing the right paper for your children’s book isn’t rocket science. But it does require understanding the basics of paper types, weights, and finishes — and how they interact with your specific content, audience, and budget.

Here’s a quick recap of the key takeaways:

• Art paper (coated) is best for illustration-heavy picture books
• Woodfree paper (uncoated) is best for text-heavy readers and activity books
• 157gsm art paper is the sweet spot for most children’s book inner pages
• 350gsm + 350gsm cardboard is the standard for board book pages
• Always use lamination on covers — no exceptions
• Always request paper samples before a large print run
• Always confirm safety certifications (EN 71, CPSIA, FSC) for your target market

Frequently Asked Questions

Can I use recycled paper for children’s books?

Yes, recycled paper is available for children’s book printing. However, recycled paper typically has a slightly lower brightness and may not reproduce colors as vibrantly as virgin fiber paper. If color accuracy is critical (as it usually is for picture books), we recommend FSC-certified virgin fiber paper instead — it’s still environmentally responsible but delivers superior print quality.

What is the minimum order quantity for children’s book printing?

Most offset printers (including us) have a minimum order of around 500 copies. For smaller runs (100–500 copies), digital printing is an option, but per-unit costs are significantly higher. If you’re testing the market with a new title, digital printing for a small initial run followed by offset printing for larger orders is a smart strategy.

How do I know if my paper meets EN 71 or CPSIA standards?

Your printer should be able to provide test certificates from accredited laboratories (such as SGS, Bureau Veritas, or Intertek). These certificates confirm that the paper and ink used in your book comply with the relevant safety standards. Always request these certificates before your first order — especially if you’re selling in regulated markets like the EU or US.

Should I choose glossy or matte paper for inside pages?

For inside pages, this is usually a choice between glossy art paper and matte art paper (both are coated). Glossy inner pages make colors look more vibrant and saturated. Matte inner pages reduce glare and feel slightly more premium. For most children’s picture books, glossy or semi-glossy is the standard. Matte inner pages are a great choice for photography-based books or books with a more artistic, subdued color palette.

How much does paper choice affect the final cost of my book?

Paper typically accounts for 30–40% of the total printing cost. Switching from 157gsm to 128gsm art paper can save 5–10% on overall costs. Switching from art paper to woodfree paper saves even more. But remember: the paper is what your readers see and touch. Cutting costs on paper is usually the last place you should look to save money.
