Gutter and downspout size for Sherman rain
What overwhelms a gutter is a burst, not a season. In Sherman the five-minute rain expected about once in ten years falls at 7.68 inches an hour (NOAA Atlas 14 Volume 2). At that rate one 2-by-3-inch downspout drains about 940 square feet of roof and one 3-by-4-inch downspout about 1,880, by the rule in the Copper Development Association’s design handbook.
