Sleep Hours by Age: Recommended Ranges
One chart, every age band: the sleep-hour ranges published by CDC-referenced consensus sources, restated as-is. Use the lookup for a single age, or print the table and keep it with your sleep diary. Informational reference only — not medical advice.
Age → recommended sleep hours
Enter an age in years to look up the recommended sleep range for that age band. Pure lookup — it restates published organization recommendations and nothing else.
The full table is below — the lookup is just a shortcut for one row of it.

The full chart

Totals are per 24 hours. For the three youngest bands the recommendation includes naps, because infants and toddlers get much of their sleep in daytime naps.

The adult band (18–60) is published as a floor — “7 or more hours” — rather than a closed range. That is how the source states it, so that is how the chart states it.
How to actually use this chart
A recommendation range is a reference point, not a target to hit or a grade to fear. The most practical use is pairing it with a log: note your bedtime and wake time for a couple of weeks, then read your own “hours in bed” column against the band for your age. If your rows sit far from the published range and you feel fine, that is an observation to bring to a professional — not a problem to self-treat. If they sit far from it and you feel worn down, that is the same observation with more weight.
Two reading notes keep the comparison honest. First, the chart counts time asleep, while a diary records time in bed — falling-asleep time and night wakings sit between the two numbers. Second, ranges are population-level consensus figures; individuals vary around them. The ranges answer “what do major health organizations publish for this age?” They do not answer “how much do you need” — no chart can.
If you want to start logging, the 2-week sleep diary has an “hours in bed” column built in, and the how-to guide walks through filling one in.

This page restates published recommendations and links to the originals. It is verified against the CDC page above (last verified 2026-10-17), with a scheduled annual re-check each March (World Sleep Day window) plus event-driven updates if the source organizations revise their guidance. Restating ranges is all this page does — it adds no interpretation of what the ranges mean for any individual’s health.
