Is 9 hours of sleep enough for a school-age child? (6-13 years)
Updated October 3, 2026 · Sources: NSF panel 2015 · AASM 2016/2015
Short answer
Yes
School-age childs aged 6-13 years are recommended 9–11 hours per 24 h. 9 hours is inside that range.

What the panels say about 9 hours for school-age childs
For school-age childs (6-13 years), 9 hours sits inside the 9–11 hour range the National Sleep Foundation panel recommends. The American Academy of Sleep Medicine's pediatric consensus gives 9–12 hours for this group (AASM uses ages 6-12 years), so 9 hours also passes by that measure.
It is the minimum of the range. The ranges include daytime naps for under-fives, and both panels stress that a child's needs change month to month.
One hour less (8 h) would be in the may-be-appropriate band; one hour more (10 h) would be within the range. Holding this on school nights and weeknights alike matters more than the exact figure.
In cycles
9 hours is roughly 6 sleep cycles at the 90-minute adult average (9 h); cycles run 70–120 minutes, so treat the count as approximate. For a school-morning bedtime, count back from the alarm with the bedtime pages and add the extra hours this group needs.
