How big are hailstones?  That definitely can depend on where you live and how strong an updraft the storm has that produces them! The best way to find out how large the hail might be that fell in your yard is to take an actual measurement. Depending on what the diameter is in inches will determine the size. The chart below, as provided by the Storm Prediction Center, shows how hail is typically measured.
