Page Count Pitfalls: How to Choose the Right Exercise Book (100/120/140pg) for Your Child

The Backpack Avalanche

When 9-year-old Mei unzipped her bag, a confetti of torn pages erupted—half-finished math grids stuck to banana-smeared essays. “My book exploded, Mama,” she whispered. That night, teacher-parent Ms. Chen made a grim tally:

• 3 ruined 48-page books (too thin for term work)

• 1 deformed 192-page tome (bulk cracked spine)

• 17 loose sheets from “custom” brands (failed stitching)

Her epiphany came while measuring Mei’s handspan: “Children need Goldilocks notebooks—not by guesswork, but science.”
