The size of a baby quilt can vary greatly depending on the quilter's intentions. They are usually between 36 inches by 36 inches and 52 inches by 52 inches, but could be sized differently.
Generally, the manufacturer's standard size is 36 inches by 54 inches. As quilts are often handmade, the ultimate size is up to the quilter and may depend on the design. Some baby quilts are intended only for use as a stroller or car seat cover; these are around 25 inches by 30 inches to accommodate that purpose. A quilter who intends to make a quilt to grow with the child may opt for a larger size.
