Round Downspout Sizing Charts

We offer these Downspout Sizing Charts because
some Round Downspout Diameters are very close. Depending on the Downspout Bracket type that you are ordering – this information may or may not be an important factor as most of our designs are forgiving for size variations between downspouts.
We try and manufacture our products for snug and best fit.
If your quote indicates “Confirm Manufacturer or Downspout Diameter/Circumference” the bracket style you are ordering is a less forgiving style.
Our default size is highlighted in Patina Green.
If you are unsure of your exact downspout diameter
please use one of the charts to confirm.
