I have 2 featherweights A brother pacesetter and now I have a new featherweight Brother which I will use in class Both singer featherweights are really not that light for me but the new brother is so light I forget I have it in my hand lol One of my singer feather weight does not work but it sure looks nice on a shelve in my sewing room So to really answer your question they are light enough to carry and won't hurt your back and sew fabulous
