Introduction
The size of the downspout you need for your 6 inch gutter system depends on a few factors, including the slope of your roof and the length of your gutter run.
A 6 inch gutters is a common size for residential homes. The size of the downspout you need will depend on a few factors, including the slope of your roof and the length of your gutter run. Downspouts are typically available in 2×3 inch, 3×4 inch, and 4×5 inch sizes.
For most applications, a 3×4 inch or 4×5 inch downspout will be sufficient. If you have a very long gutter run or a particularly steep roof, you may need to use a larger size downspout to prevent clogs and overflows.
Downspout Sizes
In order to find the size downspout you need for a 6 inch gutter, you need to know the length of the gutter and the amount of rainfall in your area. The length of the gutter will determine the size of the downspout.
3 inch downspouts
A 3 inch downspout is able to handle 246 square inches of rainwater coming from a 6 inch gutter. This is based on the industry rule of thumb which says that a roof’s drainage area should be no more than 1/16 of an inch for every foot of rainfall.
So, for example, if your home is in an area that gets 48 inches of rain per year (4 feet), you would need a minimum of 3 inch downspouts. A 6 inch gutter can handle up to 2 times the amount of rainwater as a 5 inch gutter, so it is a good idea to upgrade if your old gutters are that size.
4 inch downspouts
Downspout sizing for gutters is not an exact science because there are several factors that come into play, such as the type of gutter, the amount of rainfall in your area, and whether or not the gutters are being used to collect water for plants or other purposes.
In general, though, most experts recommend using 4 inch downspouts for 6 inch gutters. This is because 4 inch downspouts can handle about 22 gallons of water per minute, which is more than enough for most homes in average rainfall areas.
If you live in an area with excessive rainfall, you may need to use larger downspouts or multiple downspouts to prevent your gutters from overflowing. You should also consider using larger downspouts if you are collecting water for plants or other purposes, as you will need to account for the extra water volume.
5 inch downspouts
5 inch gutters are the most common size used on residential homes. Most residential homes will have a concern for Aesthetics over Function. In this case, you would use a 3×4 Aluminum or Steel Downspout. This will give the look of a larger gutter, but with about half the capacity. If you had a home that was prone to ice damming or had large trees near your home, you would use the larger 6×5 Downspout. The 6×5 is twice as strong as the 3×4 and can handle about twice the water volume.

What size downspout do you need for a 6 inch gutter?
The size of the downspout you need for a 6 inch gutter will depend on the length and slope of the gutter run, as well as the volume of rainfall in your area.
For a 6 inch gutter, we recommend using a 2×3 inch downspout for runs up to 40 feet, and a 3×4 inch downspout for runs over 40 feet.
If your area experiences high volumes of rainfall, you may need to use a larger size downspout to handle the increased volume of water.

The rule of thumb is that you need one downspout for every 20 to 30 feet of gutter, depending on the slope of your roof. So, if you have a 60-foot section of gutter, you will need between two and three downspouts. It’s always better to err on the side of too many rather than too few, because if your gutters are overloaded with water, they can pull away from your house or collapse.
