What is the proper placement for downspouts?

There are a few things to consider when determining the proper placement for downspouts. First, consider the location of the gutters. Downspouts should be placed near the corners or end of the gutter run to allow water to drain properly. Second, think about the height of the downspouts. They should be tall enough to allow water to drain away from the foundation of the house, but not so tall that they become a tripping hazard. Lastly, take into account the slope of the ground around the house. The downspouts should be placed in a way that allows water to drain away from the foundation and not pool around the house.

What is the formula for calculating downspouts?
