Crib Mattress Dimensions

You need to compare the crib mattress dimensions with the dimensions of your baby crib in order to determine if it's the right and safe fit.

A standard baby mattress will have the following dimensions:

• length = 51 5/8 inches
• width = 27 1/4 inches
• height/thickness = no more than 6 inches

But keep in mind, many crib mattresses will have slightly different dimensions. This is ok, only if the mattress fits very tightly in the crib. Meaning, you should not be able to fit two finger widths between the mattress edges and the inside of the crib. Otherwise, the mattress is too small (or crib is to big) and this is a potential safety hazard for your baby.

Parents need to understand that baby limbs are very tiny, and as result they may get caught in between even very small spaces. That's why I recommend that you measure the mattress prior to placing it into the crib.

There are several key factors you need to look at prior to buying the baby mattress. Proper dimensions is just one. Firmness and what it's made of is also very important.
