Thanks for posting! I measured the end of the flat edge of the hinge where the three hole are located to the center of the hole on the part that attaches to the cabinet. That measurement came to 1-7/16". The flat part of hinge with the three holes is 1-1/2" x 1-1/4". After the holiday we will update the measurements on the store page. I hope this helps!
