Here's the site I use for blanket sizes-about half way down page in bold type: http://knitting.about.com/od/knittingskills/a/blanket_sizes.htm. Says standard baby blanket size is 45x60 inches. When I've made baby blankets, I've made them closer to the actual crib size (28x52), because you don't need them to drape over the sides like a regular blanket.
Here are some tips to help you decide a good size blanket for the age of your baby. Usually, a crib blanket is about 36 x 52, and will cover a standard crib mattress. While this blanket is wonderful for covering baby's crib, it's not quite as wonderful covering for baby. A crib blanket is just too big for swaddling a newborn. And we all know that a swaddled baby is a happier, more content baby.
