Increasing the slope of the gutters can increase their handling capacity. The basic rule for the size of the gutters is that, when in doubt, the bigger the better. Creating a gutter system that is too large for a house would be difficult. However, bigger also means more expensive. Here's how to find the minimum gutter size you'll need.
The size of the gutter refers to the width of the gutter. The most common size of gutters is 5 inches, but some homeowners opt for 6 inch gutters to withstand more rain. There are also 4- and 7-inch gutters, but they are smaller common. Homeowners who live in areas with heavy rain or that have steep roofs may opt for larger gutters to handle increased runoff.
