5 Inch vs 6 Inch Gutters: Which Size is Best for Your Home?

Jul 4, 2023 | Uncategorized

If you’re planning on getting new gutters installed on your home any time soon, you may be wondering what size gutter will work best for your home – 5 inch vs 6 inch gutters?

Maybe you’re wondering why the size even matters, after all, just a 1 inch difference can seem rather trivial to some homeowners. 

However, gutters play a critical role in protecting your home from water damage. This water, if not properly redirected, could wreak havoc on your home’s foundation, potentially leading to flooding, erosion, and even structural instability.

That extra inch can result in a gutter that’s capable of holding and draining up to 50% more water than its 5-inch counterpart. Simply put, a 6-inch gutter will be capable of handling more water, though in some cases a 6-inch gutter may not be necessary. 

We’re here to shed some light on this question, and help you gain a better understanding of when and why you should opt for a 5-inch vs 6-inch gutter, and better inform you of what size gutter you should choose for your next project!

Key Differences Between 5-inch and 6-inch Gutters

Size Comparison and Water Capacity

The most obvious difference between the two is their size, which can easily be seen in the width when the two options are side-by-side

This single inch difference has a significant impact on the amount of water that the gutter can handle. 

A 6-inch gutter can carry away approximately 50% more water than its 5-inch counterpart, making it a suitable choice for homes located in areas prone to heavy rainfall, or homes with larger roofs where more water is collected (more on that in a second).

Visual and Aesthetic Differences

The visual impact of your gutters is another important consideration. 6-inch gutters, due to their larger size, have a more prominent appearance. This can add a certain architectural detail to your home’s exterior and may complement larger, more expansive homes better. 

However, 5-inch gutters are less noticeable and might blend better with smaller houses or those with a more subtle architectural style.

Another aesthetic factor to consider relates to your home’s fascia boards. If you have larger fascia boards, you will likely want to avoid 5-inch gutters as it will give off a smaller and unaesthetic appearance. 

For example, a 1”x8” fascia board would look best with a 6-inch gutter, whereas a smaller fascia board like a 1”x6” would look best with a 5-inch gutter. 

How The Size & Shape of Your Roof Plays a Role

Size of Roof (Roof Plane)

The size of your home and, by extension, your roof is a critical factor in deciding the right gutter size. Larger roofs collect more water, and as such, require gutters with a higher water capacity. 

A small home or roof (600-1000 square feet) might be perfectly served by 5-inch gutters. However, if your home or roof is particularly large (1500+ square feet), it might be better suited to 6-inch gutters, which can handle a higher volume of water.

Pitch of Your Roof

The pitch, or slope, of your roof will also need to be a consideration when choosing between 5 & 6 inch gutters.

The steeper the pitch of your roof is, the faster rainfall is going to flow down the roof and into your gutters. 

Say you have a 5-inch gutter on a 10/12 roof or above. There is a decent chance that rainfall will overshoot the gutter, and begin to pool around the base of your house. This is due to the high velocity at which the rainfall is flowing down the roof.

So even a house with a smaller roof size, but a steep pitch, may be best suited for 6-inch gutters. 

Weather Considerations for Gutter Selection

Amount of Rainfall in Your Area

The volume of rainfall your home receives is a key factor in choosing the right gutter size.

If you live in an area with frequent heavy rainfall, a 6-inch gutter’s higher water capacity may be necessary to efficiently handle the volume of water you receive in your area. 

On the other hand, if you live in drier climates that experience lighter, less frequent rain, a 5-inch gutter is likely to suit your needs just fine!

Climate in Your Area

It’s not just about the rain, though. The overall climate will also influence your choice. For instance, if you live in an area prone to snow and ice, larger gutters can be beneficial as they can handle more water during thaw cycles. 

On the flip side, in warmer climates with minimal rain or snow, the extra capacity of 6-inch gutters might not be necessary, and 5-inch gutters are more than suitable.


The difference between a 5-inch and a 6-inch gutter, while seemingly minimal, can have a significant impact on how effectively your gutter system performs the essential task of channeling water away from your home. 

In a lot of cases, 6-inch gutters may be the better choice seeing as they can handle around 50% more water than 5-inch gutters, they’re less likely to clog, and overall offer better water management. 

6-inch gutters also do tend to cost slightly more than 5-inch gutters, though the benefits tend to outweigh the increase in price. 

All that being said, 5-inch gutters are still a great choice for homeowners in many cases. 

So when weighing the options of 5 inch vs 6 inch gutters, it really comes down to your unique needs. 

How big is your house?

What is the pitch of your roof?
Do you live in an area prone to heavy rainfall or harsh winters?

By answering these, you’ll gain a clear understanding of what size gutter will work best for your home.

Gutter Dunn provided us a reasonable quote for soffits, facia, eavstroughing and gutter guards. We were dealing with improper airflow which was as a result of additional roof venting when a new roof was installed. They were able to open up the older wood soffits before adding new soffits. Employees are friendly and knowledgeable about their product. We are very happy with their work which was done efficiently and in a timely manner and the house looks great! They got the job Dunn! Thanks

Took a while to get a quote but well worth the wait. Everyone from the Estimators, Office Staff, Scheduler, and Installers were first class.They explained what was available and what they would recommend. We chose not to go with the leaf protection as we have a 1,200 sq. ft. bungalow and not that much gutter on either our garage or house. It's easy for us to just flush same.FYI their competitors Sales Rep provided a verbal quote and insisted we needed the leave filters and offered at least 5 different discounts and would have charged us double the price that Gutter Dunn invoiced. Competitor would not provide a written quote so I was leary about this company and their Rep.Installers were terrific, showed up a little early and reviewed the scope with us... They also installed new downspouts into our existing storm drain system. What a difference, they inserted the downspout into a pvc fitting vs the old tee pee cone style fitting.They were here for about 3.5 hrs and had everything cleaned up and put away.You know you are dealing with Professionals when they show up in a custom truck with Gutter Dunn and their suppliers ads screened on the side of same. The installers also wore company hats, tees and they were keen to do the work.If I could rate them as a 6 if I could, thanks again Gutter Dunn.

They are an absolute delight to work with. I had my old wooden soffit removed and replaced. They were quick to get it done, from the first phone call to them being done was maybe two weeks and it involved coordinating with another contractor to fix the roof. Great communication, called if there was a problem or question, sent easy to understand emails. I can't say enough good things. The work they did was worth every penny.

What a great company. They listen to what you want done and then do it. I'll be using them again and now setting up annual gutter clean outs.

Had soffits/fascia and eavestroughs completed by Gutter Dunn. Both crews were very professional and we are very happy with the final product. The office staff were very helpful as we navigated some other construction delays that affected the scheduling of the Gutter Dunn crews, much appreciated!

So happy with this Company! They were a little longer getting to me than quoted but worth the wait for the service and attention to detail. They have more selections for qutter profiles than most companies I contacted and they color matched my troughs perfectly to blend in with the exterior. Pricing was also very comparable to other companies when comparing installation techniques. Branden made me an extra extension for my rain barrel in summer, and changed a run on the garage I wanted reversed due to the slope. No hesitation to make it perfect for me. He made sure I loved everything before leaving. My favourite was the duel color downspout to match my exterior. Looks perfect! Thanks for Gutt N’ ER’ Dunn 🙂

I am really happy with how everything went! i picked gutter dunn because of how they came across and the quoting process where they understood what i wanted, so i did not pick them because they were the cheapest but totally competitive in the market and i felt they would get the job done. in the end the design desired was followed and the installer communicated really well to verify. Really happy!
