Crib Slat Spacing
Authority: U.S. CPSC 16 CFR 1508 / 1509
US federal crib safety regulation caps the gap between crib slats at 2 and 3/8 inches, about the width of a soda can. This prevents an infant's body from slipping through while the head stays trapped, which was historically a leading cause of fatal crib entrapment before the rule.

Origins of the Federal Slat-Spacing Rule
The US Consumer Product Safety Commission first issued mandatory safety regulations for full-size cribs in 1973, codified at 16 CFR Part 1508 under the Federal Hazardous Substances Act, with a companion rule for non-full-size cribs following at 16 CFR Part 1509. The maximum 2 3/8 inch (6 cm) gap between slats, spindles, and other crib components was part of this original standard and was later amended in 1982.
Regulators and safety advocates have credited this spacing limit with sharply cutting the rate of fatal head and neck entrapments that were common in older cribs built with wider, more decorative slat spacing before the rule took effect.
The 2010-2011 Crib Standard Overhaul
By the late 2000s, more than 11 million cribs had been recalled since 2007, and drop-side cribs in particular were linked to dozens of infant deaths from suffocation and strangulation caused by hardware that could detach and create dangerous gaps. In December 2010, the CPSC voted to approve consolidated new federal crib safety standards, and the rules took full effect on June 28, 2011.
The overhaul banned the manufacture and sale of traditional drop-side cribs, required stronger mattress supports and more durable hardware, and mandated more rigorous safety testing. It was the first major update to federal crib standards in nearly three decades. Child care centers, family child care homes, and public accommodations such as hotels were given a compliance window before the new rules applied to cribs already in their use.
