DogMom1i measured my bag at home and it measures the same as the medium. Which mean from left to right or width is the first number. From the crank of your machine to the needle end. I would like to know how much they weigh?
sla9997The cases offered are only listed in a Medium and a Large size. If the measurements are in inches not centimeters then the first measurement is 40" I know of no sewing machine base that large other than a lomgarm which would be too heavy.
