Crib Mattress Size Standard
Crib mattress size – When you buy a crib and bedding that goes with it, it’s easy to get excited about colors, graphics and matching the interior of the child’s room. Even if you know a mattress is needed, it’s usually not the part of the crib that gets the most attention. However, mounting a mattress properly is one of the most critical issues, because a badly equipped mattress can cause damage to your child or even death by suffocation.
Measure the length and width of the interior of your child’s crib with a tape measure. Take your measurements and measurements with you when shopping for a crib mattress size on a children’s furniture or department store. Although the standard mattress size for a crib is about 52 by 17 inches, there are small variations in the actual size determined by the manufacturer.
Measure the length and width of the mattress you plan to buy. The crib mattress size standard measures at least 51 5/8 inches long with 27 1/4 inches long. Compare it with your notes to make sure it matches the measurement you took in the crib. Set new mattress inside the crib and place your finger between the mattress and the side of the crib. If it fits easily, put a second finger right next to the first one. If the two fingers fit within the space the mattress is too small and is a safety hazard.
