crochet baby blanket sizes chart
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.
