I have seen them vary from destroyed saplings up to 6-7 inch cedars, the cedar rubs are neat because the fresher they are the more shaving there will be and the stronger the smell. I have never put a lot of faith in relating the size of a rub to the size of the deer, however a big buck will do some serious damage to 1-2 inch saplings, I have seen more than one torn out of the ground.
