Almost everyone wants a pergola in their backyard. It adds a certain level of elegance and class to any space.

You can also decorate the area in all sorts of ways. Adding a dining table or a seating nook are just some of the many ideas.

Another great addition to the place can be a swing. Can a pergola support a swing, though?

The answer is yes. A lot of pergolas can support swings with no issues. It will all depend on the construction of the structure, and the lumber used will play a role in managing the weight of the swing.

Let’s take a look at pergolas and how you can add a swing to your favorite area.

Pergola Structure

We all know how beautiful pergolas can be, but most of us don’t know how they stand upright.

Standard pergolas usually have columns and a roofing grid. There are eight main beams that support most of the weight of the structure.

You place four of the columns straight into the ground. For this, you’ll have to dig holes that are at least 3-4 inches deep, and then you cement over the entire area.

After you plant the support columns firmly, the other four beams connect them at the top. This gives a sort of cuboid shape.

On top of all of that, you have the roofing grid or rafters. These are narrow planks that create the ceiling portion of the pergola.

This area of the structure isn’t load-bearing. That means it can’t support much weight other than its own. However, the beams can handle a little more. The way weight distributes over the eight beams allows them to do a bit of heavy lifting.

Pergola Materials

The weight capacity of your pergola will change based on the materials you use for support.


The most common material people use for pergolas is standard timber. Traditionally, you’ll have eight 4×4 posts that provide the main structure.

Wood is an easy way to smoothly transition from indoors to outdoors. Not only is it amazing to look at, but it has high tensile strength. That means that the wood can handle the weight of a swing.


If you have a metal pergola, then you’re in luck!

As we all know, steel is much stronger than wood. So, a metallic structure can handle more weight. For this reason, you should be able to hang a swing or a hammock.

However, metal can rust without proper care. This may compromise the stability of your pergolas. In that case, it won’t even be able to carry its own weight.


Fiberglass pergolas are a little rare. They provide an elegant, formal flare to any space.

These structures are much stronger than wooden and metallic ones. That means you should be able to add a few swings with no problems.

In addition, fiberglass is weatherproof and won’t warp over time. Yet, the material is expensive, so drilling holes to hang a swing may not be the wisest choice.

Reinforcing Your Pergola

When most people build pergolas, they add them as decorative items. They focus on the overall look of the installation without regard for the structure.

This works great when you plan on leaving your pergola as is. However, adding a swing to it may cause the whole construct to fall apart. To avoid this, you may need to reinforce it.

If you’re worried your pergola won’t be able to carry the weight of a swing, there are a few things you can do.

  • Place the railing on the side to increase the weight limit of each post.
  • Remove any damaged or rusted posts.
  • Add diagonal bracing between the four support columns.
  • Increase the depth of the support holes and plant the pergola into more solid ground.

Some of these are easier to achieve than others. For example, adding a railing on the side is simple and can increase the tensile strength of your posts.

As for increasing the depth of support holes, this one is a little more tricky. This means you’ll have to dig out your original posts. If you cemented the ground, then this is almost impossible.

Still, if you can make the holes a little deeper, you want about a third of the posts to be underground.

Adding a Swing to Your Pergola

Now that you reinforced your pergola, you’re ready to hang the swing! Let’s dive into the steps of how you can do that.

Step 1: Measuring

The first step in the hanging process is finding out how far down the swing will hang. You can do this by holding the swing up in the pergola and seeing where you want it to go.

Remember that the swing should be far enough from the ground to avoid scraping. It also needs to be low enough for you to get on without a booster chair.

Measure the distance from the top of the pergola to the support hinges on the swing.

Step 2: Cutting

Once you have the perfect height, it’s time to cut your chains. All your chains should be the exact same length so that the swing stays balanced.

This brings to mind the phrase “measure twice and cut once.” As soon as you make a decision with bolt cutters, you can’t take it back!

For this reason, you want to take your time with this step. To help you get the perfect cut, you can use masking tape to mark different sections on the chain.

Step 3: Choosing Placement

Now, we can move on to choosing where the swing will go. For this section, steer clear of the roofing and rafters.

Focus on the vertical and horizontal beams. Ideally, you want to pick a corner where three posts intersect. This will give you the most support for the swing.

Use masking tape to mark the position you chose. Make sure you account for the width of the swing.

Step 4: Drilling

This is probably the toughest part of the project. Carefully pick up your drill and make your way to the masking tape you left behind.

Figure out which eye bolt you’ll need, then use a drill bit that’s one gauge smaller. Doing so will ensure a snug fit.

Step 5: Securing

Once your drill holes are ready, carry over your chains and eye bolts. Drive the bolts through chains and holes and use nuts to secure them.

Step 6: Hanging

Now comes the easiest part!

Using a snap hook, connect the free ends of your chains to the swing. After that, you’re ready to reap the rewards of your hard work. You and your family can enjoy swaying in the open air.

Final Thoughts

Can a pergola support a swing? Yes, it can, but this will depend on the material it’s made out of. Wooden pergolas can handle a small swing with a low weight capacity. Metallic and fiberglass pergolas can withstand much more heavy lifting.

You can also reinforce your pergola to ensure it can handle the extra load. Add horizontal beams or railing to add a little support.
