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.

1 Fitted crib sheets are available a la carte for $20 plus shipping.  Blanket Nursery blankets are crib-sized and measure 36â wide by 50â long. These blankets require 4 yards of fabric. You choose which cotton fabrics will be used on the front, back, and border of the blanket. You may choose to use minky fabric on the backside of the blanket if you wish.
