Measuring straight across from the inside edge of the bar to the tip of the leaf on the pad is 7-3/4" (well 7-5/8" on one and 3/4 on the other - they are hand made.) It's a 12 inch ruler but has markings to 12-1/2" plus about 1/2" of sideways markings. Overall it is 13" long.
Notice that the bar that is in the dog hole is not a full 3/4" diameter. That is what makes it work in my thicker bench top. There is wiggle room to make it grab and hold. The Gramercy holdfasts are much closer to 3/4" diameter and didn't work very well at all. They seem to work best in a 2-3" thick benchtop.
