What a ratio is
What a staff-to-child ratio means
A staff-to-child ratio is the most children one adult may care for at the same time. A ratio of 1:4 means one adult for every four children, so a room of eight babies needs at least two caregivers. Each state sets its own ratios in its licensing rules, and most also cap the size of a group in one room.
Ratios get looser as children grow: babies need the most hands, and school-age children the fewest. The table below shows each state's center ratio at five ages, from the national database of state licensing rules kept by the Administration for Children and Families. Only 3.8% of the daycare websites we read post their ratio, so ask on your tour.

1:4 means one adult for every four children. Lower second numbers mean fewer children per adult.
Home daycares
Home daycares follow different rules
Home daycares follow separate limits. Most states set a total number of children one provider may care for in a home, with a lower cap on babies, and a larger limit for group homes with two or more providers. A few states do not license a one-provider home as its own type of care. Each state page gives its home daycare rules in the national database's own words.
Questions
Questions about daycare ratios
What is the most common infant ratio in daycare centers?
1:4, one adult for every four babies, is the rule in 33 states. Another 13 states allow 1:5 and 3 allow 1:6, while 2 require 1:3.
What does a 1:4 ratio mean?
One adult may care for up to four children at a time. A room with eight babies needs at least two caregivers; a room with nine needs three.
Are ratios the same for home daycares?
No. Home daycares usually have a total limit on children per provider, often six, with a lower limit on babies. Each state page lists its own home daycare rules.
How can I tell whether a daycare keeps to the ratio?
Count the adults and children in the room on your tour, at drop-off and at pick-up if you can, and read the daycare's state inspection record for supervision and ratio citations.
Rules change. Before you rely on a number here, check your state's current licensing rules or ask the state licensing agency.
