Arm yourself with this knowledge before your next board book project to ensure optimal durability, safety and reading enjoyment.
What Exactly is a Children’s Cardboard Book?
A children’s cardboard book refers to books intended for babies and toddlers made out of thick, durable cardboard pages rather than normal paper pages. The pages are printed and bound in the same way as a paper book, but the card stock ensures greater durability.
Board books are designed specifically to withstand rough treatment from little hands. Their sturdy construction means they can be chewed on, dropped, thrown about and subjected to all manner of toddler antics. The thick pages are also easier for infants to grasp and turn.
In addition, board books often employ rounded corners and wipe-clean surfaces to enhance safety. Bright colors and appealing imagery capture young children’s attention and imagination. Simple stories and concepts aid cognitive development.
Overall, board books strike the perfect balance between being informative and engaging for pre-schoolers, while robust enough to survive plenty of love from the little ones!
Now that we know what a board book is, let’s look at how to determine the optimum thickness.
Key Factors in Choosing Children’s Cardboard Book Thickness
The ideal thickness for a children’s cardboard book depends on several key factors:
Age of Child
A book designed for a 1-year-old learning to grasp objects requires a thinner board than one created for a 3-year-old with developing fine motor skills.
Books for the youngest readers have thicker pages that are easier to grasp and turn. Board books for pre-schoolers can be made from slimmer boards once children gain competence at handling books.
Book Dimensions
Board thickness specifications vary in relation to a book’s dimensions. A small 6” x 6” square board book requires less rigid covers than a larger 10” x 8” portrait book to achieve sufficient support.
Guidelines for ideal thickness based on book size will be covered in detail later in this article.
Page Count
More pages equal more weight and leverage on the book’s spine, necessitating a thicker foundation. Simply put, the higher the page count, the thicker your board stock selection should be.
For example, an 8-page board book spine can withstand a slimmer board stock than a 20-page book.
Type of Card Stock
The type of cardboard sheet used, be it wood pulp-based gray board or higher grade cotton fiber white art board, also impacts thickness specifications.
Lower density gray boards require a thicker sheet, while firmer white boards enable leaner calipers at equal weights. We’ll take a closer look at paperboard grades shortly.
By taking these essential factors into account, you can zero in on the “sweet spot” that achieves necessary structural integrity without over-engineering a book beyond a young child’s dexterity.
Next let’s check out some technical recommendations for ideal thickness based on book dimensions.
Ideal Thickness Guidelines for Children’s Cardboard Books
To determine the optimum caliper (thickness) for your cardboard book, cross-reference the dimensions with these practical guidelines:
Small Board Books (5.25” x 5.25” and Under)
- 6 to 10 pages – 0.06” aka 1.5mm board
An ultra-slim volume like a lift-the-flap or peek-through book. Sturdy yet slim enough for tiny hands. - 10 to 24 pages – 0.08” / 2mm
Ensures good support on a pocket/palm-sized book without too much heft. - Over 24 Pages – Consider two 0.06” boards glued, or one 0.09” / 2.3mm stock. Counterbalances a longer book while enabling easy page turning.
Medium Board Books (5.5” x 8.5”)
- Up to 16 Pages – 0.07” / 1.75mm
The standard for a mid-size paperback board book like <em>Goodnight Moon</em>. - 16 to 28 Pages – 0.09” / 2.3mm
Supports the average portrait toddler book length without getting too heavy. - 28+ Pages – Consider 2-up 0.07” boards or single 0.11” / 2.75mm stock.
Provides rigid backing for longer books kids can still lift and enjoy independently.!
Oversized Board Books (8.5″ x 11″ and Up)
- Under 20 Pages – 0.11” / 2.75mm
Heftier card stock needed despite shorter page count to eliminate large book floppiness. - 20 to 34 Pages – 0.14” / 3.5mm recommended.
Hits the sweet spot for majority of oversized picture books—sturdy yet portable. - 34+ Pages – Consider 0.17” / 4.25mm or two 0.09” sheets laminated for covers. Counterbalances books rivaling small telephone directories!
These figures reflect the optimal balance point between sufficient structural support and manageable book handling relative to dimension and page count averages.
Where higher page counts require thicker boards, glueing two slimmer sheets together equalizes added weight at spine while enabling easier page turns.
Next let’s examine the types of card stock well-suited for achieving the above thickness guidelines economically.
Paperboard Grades for Cardboard Book Printing
Commonly used paperboard types include:
White Paperboard – Made from bleached virgin fiber. Bright white surface and edges. Medium density = good value. Used for high-end board books.
Gray Paperboard – Made from 100% post-consumer recycled content. Lower grade than white board but costs 50% less. Most economical board book option.
Both perform equally well structurally despite gray board being less dense. It simply requires marginally thicker sheets to offset lower rigidity from increased recycled fiber content.
Economical gray paperboard enables producing inexpensive board books costing a fraction of standard children’s picture books—making them highly accessible for preschool programs with budget constraints.
For individual buyers or high-volume production runs aiming for maximum visual appeal, vibrant white boards justify a moderately higher expenditure.
Understanding paperboard quality differences allows striking the right balance between ideal functionality and affordability priorities when selecting thickness.
In the final section, we’ll cover easy methods for keeping overall board book printing costs in check.
Tips for Lowering Expenses – Children’s Cardboard Book Printing
Here are handy tips to keep production costs low when creating cardboard books without sacrificing quality:
Choose a Smaller Footprint
Constraining book dimensions directly reduces printing paperboard and cover stock consumption for every copy. Even marginal size decreases make a measurable difference across thousands of books.
Specify Gray Board Over White
While white paperboard looks crisper, inexpensive gray boards get the job done on a budget with little discernible difference in content enjoyment for tots.
Laminate Covers Only
Eliminate unnecessary lamination on inner spreads to pare down expenses. Gloss UV coating on covers only confers needed protection at lower cost.
Combine Streaming + Offset Printing
Stream printing initial runs to test market reception. Switch to offset lithography for economy of scale savings on larger sequel volumes once confidence of success is established.
Go Long!
Within reason…leverage press minimums by grouping book projects to print a larger load per machine setup. The more you print in one go, the less you pay per book overall. And those are your essential insider tips for engineering the ideal children’s cardboard book thickness formula without breaking the bank!
We’ve covered the critical elements of board weight, size adaptability and materials science behind constructing beautiful books for babies cost-effectively. Now you can apply these guidelines confidently for your next miniature masterpiece. Here’s to shaping young minds discovery by discovery!
