While 5-inch gutters are the standard size, some homeowners opt for larger ones. 6-inch gutters are more expensive, but they can handle large amounts of water and are less likely to get clogged.
The standard size for residential gutters is 5 inches, but homeowners can choose 6-inch gutters instead. While traditional 5-inch gutters are a common choice among homeowners, 6-inch gutters can hold significantly more water.
Gutter size is determined by measuring across the top of the gutter. To help you understand gutter measurement and dimensions, here is a relative comparison in size between 2×3 inch downspouts vs. 3×4 inch downspouts… likewise, a comparison between 3 inch round downspout and 4 inch round downspout.
While larger gutters have gained popularity, the 5-inch gutter, once considered a standard size, still remains a viable choice for some homes, particularly in certain regions of the country. It can handle average rainfall and is cost-effective, especially in areas with lower precipitation.
A 2x3 inch downspout can handle roughly 600 square feet of roof area for every inch of rainfall within an hour. On the other hand, a 3x4 inch downspout can handle twice that - 1200 square feet of roof area per inch of rainfall in an hour.
This can make installation more complex and potentially more expensive compared to K-style gutters. The unique design and potentially more complex installation process often lead to a higher overall cost for half-round gutters compared to their K-style counterparts.
5” gutters typically get the 2×3” downspout, so be aware that if you add 3×4” downspouts to 5” gutters, it will look very odd. Since work must be done to add your additional, larger downspout, now would be the best time to switch out to 6” gutters, as well.
6 Inch Gutters Have a More Robust Appearance
6 inch gutters have a more robust look. Because the size is bigger, you will have a more structural appealing look to your home. 5 inch gutters can sometimes make your home look less structurally sound.
Generally speaking, 6 inch gutters cost per foot is between $4 and $10 for most styles, though copper gutters will be more expensive per foot.
The problem with an undersized gutter system is that debris will build up and clog really fast. If you're dealing with frequent clogs and water problems, it could be a sign your gutters are too small. Oversized gutters aren't necessarily problematic, but they'll cost you a lot more than you need to spend.
As a general rule of thumb, choose 6-inch gutters for larger and steeper roofs and 5-inch gutters for smaller, low-slope roofs. Larger gutters typically hold more water, making them ideal for areas receiving heavier rains. However, different conditions may call for an adjustment in gutter size.
027 gauge is the industry standard for most residential gutters. It is ideal for areas with mild to moderate climates and light snow. If you live in a place where heavy rains, wind and snow are common, you might need to upgrade your gutters to . 032 gutters.
Roof Vs.
Trim, a relatively minor component, creates a cleaner look, and unifies both roof and siding. Gutter colors should blend in with these components; therefore it has to match either roof or trim.
Gutter Replacement: Gutters come In Different Sizes
When you are completing a gutter replacement, the first point to note is that gutters come in different sizes. They can be 4, 5, or 6 inches. Downspouts also come in different sizes, such as 2×3 inches and 3×4 inches in size.
Measure Gutter Width: For existing gutters, measure from the edge that sits against the fascia to the outer edge of the gutter. Standard residential gutters typically range from 5 to 6 inches in width.
The downspout requirements for five and six inch gutters are about the same even though gutter downspout sizes vary. The general guideline for downspouts is one for every 25 feet of gutter, with 40 feet between downspouts being the maximum limit.
If a windstorm, lightning strike, or another covered peril damages your home's gutters, your homeowners policy may pay for their repair or replacement, up to your coverage limits and minus your deductible. Your homeowners policy won't cover damage to your gutters due to negligence or wear and tear.
Gutters are an essential part of any home. They ensure water properly drains off of your roof, helping to protect the roof, siding, landscaping, and foundation from water damage. On average, gutters need to be replaced every 20 years.
While 5-inch gutters are the standard size, some homeowners opt for larger ones. 6-inch gutters are more expensive, but they can handle large amounts of water and are less likely to get clogged.
So, when it comes to gutter protection, gutter guards are essential. 5" gutter systems require gutter guards for 5-inch gutters. Same goes for 6" gutter systems; meaning they require gutter guards for 6-inch gutters. 6-inch micromesh gutter guards are the perfect solution for these problems.
How long gutters last depends on different factors, such as the material they're made of. Some gutter materials last much longer than others. Aluminum gutters can last for about 25 years, while vinyl gutters might only last for about 10 or 15 years. Copper gutters can last for many decades.
Superior Rainwater Management: The primary benefit of oversized 6” gutters is their ability to handle up to twice as much rainwater than a standard system without overflowing. This prevents water from pooling around your home's foundation, which can lead to cracks, seepage, and costly repairs.
The general rule is that there needs to be a downspout for every 40 feet of the gutter. If you follow this rule, you'll make sure that no downspout is taking in too much water. You'll also ensure that no part of the gutter is keeping too much water at any moment.
6-inch gutters are less likely to get clogged up because they can handle more water flow, and they come with a bigger outlet. If you have a small home with a roof that isn't very steep, 5” gutters will suffice. Otherwise, go for 6” gutters.
