Let’s start by looking at some of the reasons why you might want to choose this type of wood. Here are some of the biggest advantages:
- Strong. Douglas Fir is about to cope with a lot of weight. This is why it is frequently used to reinforce structures. Like the Cedar, it will also be able to withstand harsh outdoor conditions.
- Abundant. Douglas Fir is relatively easy to find in North America. This is important for a few reasons. First, you will be reducing your environmental impact. It also means that this type of wood is fairly economical. It will be significantly less expensive than a Cedar.

- Grips nails well. Nails and screws will penetrate deeply into the Douglas Fir. Because of this, it will be easy to work with during the construction process.
If you are thinking about getting Douglas Fir, there are a few things that you need to keep in mind. These include:
- More susceptible to insects. When compared to Cedar, Douglas Fir will often be less resilient. It doesn’t have any of the oils that are designed to protect it from insects.
- More maintenance. Because of the risks of rotting, you will need to spend a little more time with Douglas Fir. For example, you might need to get used to sanding and applying protective varnish.
Which One Should You Choose?
Both of these are good options to use on your pergola. Which one you decide to use will depend on what you are looking for. Generally, Cedar will be the best species. It will be able to cope well with the outdoor conditions and you won’t need to worry about the wood rotting.
However, if you are on a budget, it might be better to choose Douglas Fir. While it won’t have the natural oils to protect itself from insects, it will be strong and able to cope with a heavy load. Plus, it will be relatively affordable.
It’s also a good idea to think about the area that you are planning on installing the pergola in. If the area is vulnerable to events like earthquakes or hurricanes, it might be best to opt for the strength of the Douglas Fir.
If you are on the fence and unsure about which one to get, it’s a good idea to talk to your builder. They will be able to talk you through your options and point you in the right direction.
What Else to Look For When Choosing Your Wood
Once you’ve settled on what species you are going to use, there are a few other things you should look for. First, it’s a good idea to get untreated wood. This ensures that no harmful chemicals have been used.
It’s also worth thinking about the design of the pergola. Choose a color that grabs your eye. Both the Douglas Fir and Cedar will have a range of colors that you can pick. Or you might decide to avoid this problem entirely by opting to use paint.
There are plenty of things to consider when deciding what type of wood to use for your pergola. The good news is that both Cedar and Douglas Fir are going to do an excellent job. Ultimately, it’s up to you to decide which one you want to choose.
