These handles have a 1 3/4″ center to center attachment measurement. This means that the holes for attachment screws, when measured from the center of one hole to the center of the second hole are 1 3/4″ apart. Be sure to measure from the middle of the two holes when measuring existing holes or a handle that you are trying to match for optimum accuracy.
1 3/4″ center to center are a unique and hard to find size. Smaller handles often used on mid century furniture or some cabinetry.
