A good rule of thumb is that craters are roughly ten times larger than the impactor that created them. There is, of course, a wide range of variability here, depending on velocity and other factors.

Small craters are very uncommon on the Earth because it is so difficult for small objects to arrive at the surface with hypersonic velocity. Most such objects break up before reaching the ground.

I got this question (below) and wondered if anyone on the list
has a knowledge based answer. I could only "guess" about the
size of a basketball, but feel very much lacking in confidence
in my guess.
       Anyone?  Michael
Can you tell me about how big of a meteorite it takes to make a Crater about thirty feet across?
