No, not all crib mattresses are the same size. Here’s a breakdown of common crib mattress sizes:
Standard Crib Mattresses
- The most common type of crib mattress.
- Dimensions: 27 1/4 inches wide by 51 5/8 inches long
- The thickness should not exceed 6 inches.
- Designed for standard-sized cribs
Mini Crib Mattresses
- Smaller than standard crib mattresses.
- Dimensions: 24 inches wide by 38 inches long.
- Designed for mini cribs, which are a good option for smaller spaces
Round/Oval Crib Mattresses
- Less common than standard or mini crib mattresses
- Come in various round or oval shapes to fit specific cribs
- It’s important to find a mattress that perfectly fits the shape of a round/oval crib
Important Considerations:
- Regulations: Crib mattresses in the US are regulated by the Consumer Product Safety Commission (CPSC) for size and safety standards.
- Fit: Always ensure a snug fit between the mattress and the crib frame. There should be no more than two fingers’ width of space between them to prevent entrapment hazards.
