Bobbin measurement 7/16"(11 mm) by 13/16"(20 mm) diameter This size bobbin is used by more makes and models of sewing machines than any other bobbin. This bobbin is the same size as some of the more expensive bobbins like the Brother X52800150 (SA156) or the 102261103 Bobbin or the Singer 15J. If you want to save money this is a good substitute for the Brother SA156, 102261103 or the Singer 15J, but if you want a better quality we sell them too.
