Yes, that is the correct calf measurement. These boots aren't super high, only 9", so they would not reach the largest part of your calf.
These boots do not go up high enough to hit the widest part of my calves. The height from the sole of boot to the top of the boot is 11 inches. I am 5'7" and have 14 inch calves so unless you have Schwartzenegger calf muscles, these boots should be just fine.
