What “classroom-ready” means here
Generous x-height, dots that survive fluorescent glare, and margins that tolerate three-hole punches are baseline requirements—not luxuries. We avoid hairline traces that look crisp on a monitor but vanish on the copier, and we avoid cramming so many rows that children finish mentally before their hands catch up. That standard applies whether the page is a name worksheet, an alphabet tracing page, or a common sight words worksheet.
Neutrality matters: layouts should not feel babyish for older primary students or intimidating for brand-new writers. Line weight carries tone as loudly as clip art does.
