Yes, baby crib mattresses in the United States have a standard size to ensure your baby’s safety. This standard is regulated by the Consumer Product Safety Commission (CSPC) to prevent infants from getting stuck between the mattress and crib slats.
Here’s what you need to know about standard crib mattress size:
- Dimensions: A standard crib mattress should be at least 27 ¼ inches wide by 51 ¼ inches long (69 cm by 130 cm).
- Thickness: The mattress should not be more than 6 inches (15 cm) thick. This helps prevent your baby from climbing out of the crib as they grow.
- Slight variations: There can be a small difference in size (up to⅝ of an inch) between cribs and mattresses. However, the mattress should fit snugly inside the crib with no more than a 1-inch gap between the edge of the mattress and the crib frame.
Here’s a tip: It’s always best to check the fit of the mattress in the crib before placing your baby in it for the first time. This ensures a safe sleep environment for your little one.
