While quilt designers don't adhere to standard quilt sizes when designing, manufacturers tend to be a bit more conscientious and do follow some general guidelines.
Manufacturers use standard measurements for production
Our chart shows standard mattress, bedding and quilt sizes for the US. Measurements are approximate; there are slight variations between manufacturers.
Also listed are pre-cut, packaged batting.
After determining the quilt size you need for your bed, add about 6" to each the width and length measurements to find the minimum batting size you'll need. (Quilts to be long arm quilted may need additional batting. Check with your long arm quilter to be sure.)

While manufacturers use standard quilt sizes for production, we all know that the quilt size you NEED depends on the mattress, bed frame and the "look" you desire for the bed to be covered.
