3 Most Common Fascia Board Sizes For Gutters

If you’re looking to install a new fascia, there are three main sizes to choose from: 1 x 6 inch, 2 x 4 inch, and 1 x 8 inch.

The most common is 1 x 6 inch as it’s the standard for most homes in the United States.

But we’ll be going over each size and their specific use case. We’ll also talk about the different material types for the fascia and why it’s so important for your home.

Do Fascia Board Sizes Matter?

When choosing the fascia size, you’re probably wondering how much it actually matters. Well, the fascia is a big component of your home’s function and architecture.

If you choose the wrong size, it could mess with the installation of your gutters, not protect your home properly from water damage, and look out of place with your home’s style.

If you home and roof is built around a specific fascia size, choosing the wrong size could be a huge mistake.

Let’s walk through the common sizes so you know for sure what size fascia you need.

Fascia Board Sizes #1 – 1×6

The 1×6 inch fascia is the bread and butter of the fascia world. And by that, I mean it’s the most popular.

It’s been the standard on most homes in the United States for the last hundred years, except for a brief amount of time in the 90’s (but we’ll explain that more later).

This size fascia is actually closer to 5 3/4″, but for the sake of simplicity it’s called 1×6″.

The 1×6 size fascia board is so common because it will fit both 5 inch and 6 inch gutters, which are the most common sizes.

With a 5 inch gutter system, there will be a small amount of the fascia visible underneath the gutters when they are mounted. With the six inch size gutters, you won’t be able to see much except for the areas where the gutters are pitched.

For the 1×6 fascia, it’s standard to have a smaller sub-fascia board behind it that’s 2×4 inches.

Fascia Board Sizes #2 – 2×4

The 2×4″ fascia is definitely less common than 1×6″.

There was a brief period of time during the late 90’s and early 2000’s where this size what quite popular. But they only lasted for a brief period of time because homeowners and contractors became frustrated when trying to install gutters.

The 4″ zone makes it much harder to install gutters, when the average gutter size is five inches (and sometimes six).

When the gutters are fully installed, you won’t be able to see the fascia at all behind the gutters which can look awkward.

Many homeowners do not like the look of 2×4″ fascia, so they fell out of popularity.

If you need to replace your 2×4″ fascia, it can be worth speaking with a contractor to see if you can 1×6″ instead so you don’t have any problems installing gutters.

General home maintenance becomes more of pain with size of gutter.

Fascia Board Sizes #3 – 1×8

The 1×8″ fascia is only really found on much larger homes and it’s not for the purpose of functionality.

Homeowners and architects both enjoy the wider look of the 1×8 fascia when pair with a bigger home. It improves the overall aesthetic, making the homes look more imposing and sturdy.

If you have a normal-sized home, this larger fascia board would most likely look out of place.

There is a small benefit to this size, it’s a lot easier to install gutters because you have much more surface area to work with. You can also opt for larger gutter sizes without it looking too strange.

Fascia Material Types

When most people think of the fascia, they imagine that it’s made entirely out of wood. And while that may have been the case several decades ago, more fascia material types are common nowadays.

Let’s walk through each type.

Wood Fascia

When looking at the fascia, there are 3 main wood types used, spruce, fir, and pine.

Many homeowners like having a wooden fascia because they are both affordable and effective at doing their jobs. The biggest downside to an all-wood fascia is that more maintenance is required.

To keep your wooden fascia from rotting, as the paint begins to fall off and chip, it will need to be repainted. Any exposed wood has a bigger chance of rotting.

Fascia trim can also help protect your wooden fascia and reduce the amount of maintenance needed.

It’s also common to use pressure treated wood to reduce the chance of water damage to the fascia. While this is an effective way to fight against water damage, it can drive up the price of your fascia installation and repair.

Aluminum and Vinyl Fascia Covers

Using aluminum and vinyl fascia covers has increased in popularity in the past few years.

Because wood is still an affordable option, many homeowners opt to cover their fascia with aluminum or vinyl trim. This means the wood does not need to be painted and there is much less maintenance involved.

The covers are usually nailed into the wood.

If your home has vinyl siding, it can look more natural to have your fascia with a vinyl cover installed to match.

There are definitely benefits to these covers, such as: less maintenance, longer lasting materials, and better protection for your home.

Composite Fascia Boards

A less common option are composite fascia boards. The composite is basically a bunch of recycled wood that’s been blended up and bonded with epoxy resin to be formed into fascia boards.

These are common when looking for a certain style for your home. They are less practical as they pricier than wood.

If you have a specific color or design you are going for, these may be a good option for your project. Just keep in mind, they aren’t meant to be painted, so make sure you find the right color for your home.

They are often matched with other composite wood elements of your home, such as a deck or siding.


Fiber-cement is similar to Hardie planks that are used for siding. They are a composite of wood chips and sawdust.

You may be wondering how they are different from the last type, and while similar, they are meant to be painted to match your homes aesthetic.

If your home has Hardie siding, it might interest you to match the fascia with a similar design.

You can usually order these in an unpainted version that you can paint yourself. Keep in mind, it’s recommended to use acrylic paint for this type of fascia.

PVC Fascia Board

PVC (or Polyvinyl Chloride) fascia boards are meant as a direct placement for wood.

Nowadays, when some homeowners replace their wooden fascia, they’ll use PVC instead. It looks exactly like wood, but is typically cheaper and longer lasting.

The PVC is meant to be resistant to moisture and rotting, in addition to being paintable. So you can find the color that matches best with your home and paint it yourself (if you want, of course).

What Does the Fascia Do?

You may be wondering what the fascia even does and why it’s so important. Well, here are the four main reasons why your fascia is so integral to your home.

  • Holds up your gutters: The gutter system will get installed to the fascia with gutter hangers. So the fascia is responsible for holding it in place and keeping it from sagging.
  • Protects home from animals: The fascia covers up access to your roof from the underside, keeping out stuff like birds and creepy crawlies. Nobody likes unwanted visitors, especially the kinds that bite or sting you.
  • Keeps the water out: The most important function of the fascia is to protect your home from water damage. The fascia keeps out water from getting into your attic and the interior ceilings of your home.
  • Boosts curb appeal: A properly sized fascia can boost appeal. Bonus points if you paint it to match the rest of your homes aesthetic.

Common Fascia Problems

If your fascia is running into problems sooner than expected, it could be from one of these issues.

Fascia is Rotting

Fascia rotting is the most common problem people have with their fascia. Rotting happens when enough moisture has built up inside the fascia, creating rot.

There is a number of causes for this, including:

  • No gutters: The gutters are the first line of defense against water damage. So naturally, if your home does not have gutters, it increases the chance of water damage to your home, including the fascia. Instead of the water running down your roof and into the gutters, it instead drips down the fascia and siding.
  • No drip edge: A lack of a drip edge can contribute to your fascia rotting even if you have gutters. The drip edge is what ensures water makes its way into the gutters from the roof. If you are missing the drip edge, water will fall between the gap of the gutters and roof, dripping behind the gutters and hitting your fascia.
  • Poorly installed drip edge: A drip edge that’s not installed properly will not drain water the right way. This is quite common on homes with a low pitch. The drip edge is not installed at an aggressive enough angle, leading to water sticking to the drip edge and leaking down to the fascia.
