Baby quilts. Baby quilts can be made in a range of sizes, depending on what you want it to be used for. The standard sizes of a baby quilt is between 36″ X 36″ and 52″ X 52″. Some people like the ability of the quilt to “grow” along with the child as they become a toddler, so a larger size of a quilt is desired, which would around 46″ x 70″.
