Courtesy: NOAA/National Weather Service Pea size hail is ¼" in diameter and hail at ¾" is the width of a penny. When hail is 1" in diameter, that’s the same size as a quarter and also when hail size is considered "severe" (or large enough to potentially cause damage). Some of the most destructive hail that falls measures at least 2" in diameter! Tennis ball size is 2 ½", baseball size measures 2.75", tea cup size is 3", and softball size measures 4" in diameter. Did you know hail can be even larger than that? https://twitter.com/i/status/1258580136699420674 The biggest hailstone ever recorded was near Vivian, South Dakota in 2010, coming in at 8” in diameter! Just remember -- before you go outside to measure the size of hail that fell in your backyard, wait until the storm has moved far enough away so you can safely make your observation.
