What size should an open top pergola be?
Jan 01, 2026
When it comes to creating an outdoor oasis, an open top pergola can be a game - changer. As a leading supplier of open top pergolas, I've encountered numerous customers grappling with the question: "What size should an open top pergola be?" In this blog, I'll delve into the factors that influence the ideal size of an open top pergola and provide some guidelines to help you make an informed decision.
1. Available Space in Your Outdoor Area
The first and most crucial factor to consider is the amount of space you have in your outdoor area. Whether it's a backyard, a patio, or a rooftop terrace, the physical dimensions of your space will set the upper limit for the size of your pergola.
If you have a small backyard, say less than 200 square feet, a large pergola will likely overwhelm the space. In this case, a compact open top pergola with dimensions around 6 feet by 8 feet can be a great choice. It provides enough shade and a cozy area for a small bistro set, allowing you to enjoy your morning coffee or an evening glass of wine. You can find some suitable small - sized WPC Pergola For Exterior on our website.
On the other hand, if you have a spacious backyard of over 1000 square feet, you have more flexibility. You could opt for a large pergola, perhaps 16 feet by 20 feet or even larger. This size can accommodate a large dining table, a comfortable seating area, and even a small entertainment setup, making it perfect for hosting parties and gatherings.
2. Intended Use of the Pergola
The way you plan to use your open top pergola also plays a significant role in determining its size.
- Relaxation and Dining: If your primary goal is to create a peaceful relaxation area or a dining spot for your family, a medium - sized pergola will usually suffice. A 10 - foot by 12 - foot pergola can comfortably fit a four - to six - person dining set or a couple of lounge chairs. This size provides enough space for you to unwind without feeling cramped.
- Entertainment and Hosting: For those who love to entertain guests, a larger pergola is advisable. A pergola with dimensions of 14 feet by 16 feet or more can accommodate a larger number of people. You can set up multiple seating areas, a bar, and even a small dance floor. Our Vented Pergola in larger sizes is a great option for such entertainment - focused areas.
3. Furniture Placement
The furniture you plan to place under the pergola should be factored into the size calculation. Measure the dimensions of your existing or planned furniture, including tables, chairs, sofas, and any other accessories.
For example, a standard dining table for six people typically measures around 72 inches in length and 36 inches in width. You'll need to add some extra space around the table for people to move in and out of their chairs comfortably. A good rule of thumb is to leave at least 3 feet of clearance around the furniture. So, if you have a 6 - person dining table, you might need a pergola that is at least 10 feet by 12 feet to accommodate it properly.
4. Aesthetic and Proportional Considerations
The size of the pergola should also be in proportion to the surrounding architecture and landscape. A pergola that is too large or too small in relation to your house and the rest of the outdoor space can look out of place.
In a modern - style backyard with clean lines and minimalistic design, a sleek and moderately sized pergola will blend in well. On the other hand, in a large, traditional - style garden with a big house, a more substantial and ornate pergola can enhance the overall aesthetic. Our Garden Pergola with Roof comes in various sizes and styles to match different architectural and landscape aesthetics.


5. Local Building Codes and Regulations
Before finalizing the size of your open top pergola, it's essential to check the local building codes and regulations. Some areas have restrictions on the maximum size of structures that can be built in a backyard without a permit. These regulations are in place to ensure safety and maintain the overall look of the neighborhood.
In some cases, you may need to obtain a building permit if your pergola exceeds a certain size. Make sure to consult with your local building department to avoid any legal issues down the road.
General Size Guidelines
Based on the above factors, here are some general size guidelines for open top pergolas:
- Small Pergolas: Ideal for small backyards or intimate spaces. Sizes range from 6 feet by 8 feet to 8 feet by 10 feet. These are perfect for a couple or a small family looking for a quiet relaxation spot.
- Medium Pergolas: Suitable for most average - sized backyards. Dimensions typically fall between 10 feet by 12 feet and 12 feet by 14 feet. They can accommodate a dining set or a combination of seating and a small table.
- Large Pergolas: Best for large backyards and for those who love to entertain. Sizes start from 14 feet by 16 feet and can go up to 20 feet by 20 feet or more.
