Kids Screen Time Budgetの包括的な教育ガイドを準備中です。ステップバイステップの解説、数式、実例、専門家のヒントをお届けしますので、もうしばらくお待ちください。
The Kids Screen Time Budget Calculator compares actual daily screen time to American Academy of Pediatrics (AAP) recommendations by child age. AAP 2016 guidelines: under 18 months no screens (except video chat); 18–24 months only high-quality programming with parent; 2–5 years limit to 1 hour daily of high-quality programming; 6–12 years consistent limits ensuring screen time doesn't displace sleep, physical activity, family interaction; teens — focus on quality and balance rather than hard limits. The calculator's defaults: under 2 = 0 min/day, ages 2–5 = 60 min, ages 5–13 = 120 min, ages 13+ = 180 min. Enter your child's age and actual daily screen time; calculator outputs over/under recommendation and category. These are guidelines, not absolutes — research increasingly emphasizes content quality and context over raw time. Quality screen time (educational content with parent engagement, video calls with grandparents, watching meaningful family movies) differs from passive scrolling, mobile games, or autoplay YouTube. Research context for the limits: studies link excessive screen time to attention issues, sleep disruption, reduced physical activity, language development delays (in toddlers exposed to screens alone), and weight gain. The 2-hour limit research base traces to older television viewing; newer research suggests content quality and what activities screens displace (vs sleep, physical activity, family interaction) matters more than raw time count. Calculator gives baseline; family-specific judgment based on child's overall development matters more than hitting an exact number. How to use: track screen time for one week using iOS Screen Time, Android Digital Wellbeing, or family-friendly apps (Bark, Qustodio, Family Link). Most parents discover their kids exceed AAP limits — often by 2–4×. Reducing screen time has trade-offs: less convenience for parents, kids may resist initially, social pressure if peers all have phones. Most effective reduction strategies: phone-free meals, no screens in bedrooms, charging phones outside bedroom at night, replacing screen time with specific activities (sports, music, art classes), and modeling adult behavior (kids notice when parents are also on phones).
- 1Step 1 — Enter your child's age
- 2Step 2 — Track actual screen time for 7 days using device tracker (iOS Screen Time, Android Digital Wellbeing, Family Link)
- 3Step 3 — Enter daily average minutes
- 4Step 4 — Calculator looks up AAP recommendation: <2 = 0 min, 2–5 = 60 min, 5–13 = 120 min, 13+ = 180 min
- 5Step 5 — Computes over/under (positive = over recommendation, negative = under)
- 6Step 6 — Outputs comparison and recommendation
- 7Step 7 — Use as conversation starter and behavioral baseline, not strict ceiling
Common pattern. Reducing to 120 min often comes from eliminating background TV during meals and replacing one 'screen activity' with active play.
Teen guideline focuses on quality/balance over hard limit. 180 min as default is reasonable threshold.
Significant overrun. Common in dual-working-parent households relying on tablets as quiet-keeper. Major reduction opportunity.
Lower-than-typical screen use. Often correlates with active extracurriculars, structured family time, parent modeling.

Are AAP limits still current?
AAP's 2016 guidelines remain the active US recommendation, with 2023 supplementary statements emphasizing media quality, context, and family media plan over hard time limits. AAP now recommends every family create a customized Family Media Plan (free tool at HealthyChildren.org/MediaUsePlan) rather than strict time enforcement. The minute counts in this calculator are the original recommendations; many pediatricians now use them as starting points.
Does educational content count differently?
Yes — AAP distinguishes 'high-quality programming' (PBS Kids, Sesame Street, age-appropriate documentaries) from low-value content. Even within limits, quality matters: 60 min of high-quality engaged viewing with parent commentary differs from 60 min of autoplay YouTube. Tracking time alone misses this — content quality matters as much as quantity.
What about school-issued devices?
Educational screen time during school hours generally not counted in 'leisure screen time' — different category. However, total screen exposure across the day (school + after-school + entertainment) matters for sleep and eye health. Track all screens combined and reduce leisure if school-issued use is high.
How do I reduce screen time without conflict?
Most effective strategies: (1) Phone-free meals and family time (set non-negotiable boundaries). (2) No screens in bedrooms (charge phones in kitchen overnight). (3) Replace passive screen time with specific activities — sports, music, board games. (4) Model adult behavior — kids notice if parents are also constantly on phones. (5) Use Apple's Screen Time or Google Family Link to enforce limits automatically — works better than verbal enforcement.
What if my child's school requires screen time?
Many schools now use iPads for homework and Canvas/Google Classroom for assignments. This is educational screen time and reasonable. Concerns arise when school adds 2+ hours of homework screen time plus entertainment screen time — total daily exposure exceeds healthy levels. Talk to school about homework reasonable time. Don't double-count educational screen as leisure when calculating leisure ceiling.
プロのヒント
Use device screen time tracking (iOS Screen Time, Android Digital Wellbeing, Family Link) for accurate measurement — parental memory dramatically underestimates actual use. Most parents discover kids exceed limits by 2–4× when first measuring. Set automated limits via these apps rather than relying on verbal enforcement.
