Garbrella includes a list of the common pergola sizes available on the website. Custom kits are available and because we focus on making it easy for the installer you can modify any size while you are installing the pergola kit.
How to choose your pergola size: The 1’st number of a size is the length of the rafter (in an attached pergola it is the projection from the house) and the 2’nd number is the length of the beam. The posts are inset approximately 6” from the outside of the beam or rafter to the center of the post. Note, the measurement does not include the decorative pergola caps. The decorative pergola caps for the beams are 12” and for the rafters are 10”.
There are 4 key points in a pergola: Posts, Beams, Ledger Board (Attached Style Only), Rafters, Shade Slats.
Posts: All the Garden Spot Pergolas have a Galvanized Post Mount insert providing lateral support of the pergola. The vinyl post sleeve slides over the post mount and has routed openings to support the beam and rafter. On the “Post Type” option there are 2 sizes available (Square available) along with a few different heights. Post heights can be modified on site.
Beams: The Garden Spot Pergolas have a single beam that rests and is secured on the specially routed post. Aluminum inserts are included for each beam allowing a 16’ span from center of post to center of post.
Ledger Board (Attached Style Only): For an attached pergola, a 2×8 Ledger board is included which is the same length as the outside beams. The Pressure Treated Wood Insert is used so that you can fasten to the surface of the building. Color matched hole plugs are included to close any hole created
Rafters: The rafters run perpendicular to the beams and are secured on top of the beam using a rafter bracket (Attached Style includes a Joist Hangar) using Stainless Steel color coated screws. The posts are specially routed to allow the outside rafters to be supported at the post creating a strong pergola top. The rafters are spaced approximately 22-24” on center. Aluminum Inserts are included in each rafter allowing a 16’ span from center of post to center of post.
Shade Slats: Choosing the correct option for shade type is a simple question of do I want more shade or less shade? The 1”x3” shade slat option is our most popular and will provide approximately 60-75% shade depending on the angle of the sun.

Lighting Systems:
Many folks choose lighting as a great way to accent your pergola. Garbrella does have a small selection of lighting options including side mount lights and/or string lights. These are powered by a low voltage power supply that simply plugs into a outlet. The structure of the pergola is designed to allow you to run wiring inside the frame of the pergola providing a clean appearance.
Ceiling Fans:
Ceiling fans can be a great idea especially in a warmer climate! A small amount of air circulation can do wonders in creating a comfortable atmosphere. Another added benefit is to keep flies and mosquitoes at bay. Since flies are attracted to the smell of food and humans, they will more than likely be there to annoy you resulting in an uncomfortable experience. With a small breeze, bugs find it difficult to fly therefore there is less chance of them bothering you. Garbrella does not offer any ceiling fans, but can typically be purchased from a hardware store local to your area or other vendor. The structure of the pergola is designed to allow you to run wiring inside the frame of the pergola providing a clean appearance.
Shade Canopies or Curtains:
Choosing an overhead canopy or a side curtain depends largely on the time of day you spend outside. A canopy will provide more shade during mid-day hours whereas a side curtain is more beneficial during the morning or evening hours. Garbrella offers shade systems that can be attached directly to your pergola. Both the curtain and canopy are manually operated meaning you can open or close them with a manual crank.
An average sized overhead canopy may cost $3,000 – $4,000 depending on the size of the pergola. An average sized side curtain may cost $2,000-$2,800.
Another more temporary option may be choosing a simple curtain on a rod. The curtain rod supports can be fastened to the pergola itself and allow you to hang the curtain from the rod.

The necessary hardware and drill bits are provided for each kit. You may find our pergola installation frequently asked questions page to be helpful.
How to Install a Pergola
Installing your pergola can be both exciting and sometimes a bit mind-stretching, but your qualms can be eliminated with a few tips or by contacting a professional pergola installer!
Start by locating the general location of each post. Measure the required distance between each post. After you have the perimeter marked, square the pergola by measuring cross-corner. You can adjust the post placement, however be sure to maintain the required post to post spacing. Tip: I recommend measuring center of post to center of post. This will eliminate any confusion in relation to the post size.
If you are installing on a concrete patio or cemented pavers: this will be a breeze! Simply mark the proper location and skip on down to number 5.
Installing on wooden deck is not difficult, but the crucial part is making sure the deck frame and footings are strong enough to support the weight of the pergola. If you are unsure, contact a local inspector or contractor to confirm the integrity of the wooden frame or footings.
For a free-standing yard pergola: After locating the proper post location, dig holes that are 30-36” deep and about 16” in diameter. Place a Sonotube in each hole and fill the Sonotube with moistened Quikrete. Allow the concrete to properly dry which may take up to several days.
Fasten the post mount using our provided wood or concrete lags.
Level the post with leveling bolts and retighten all lags. You are now ready to sleeve the post with your desired size post sleeve and install the pergola top!
Installing and squaring the posts will probably be the hardest and most stressful part of installing your own pergola. So relax, your next step will probably be less exhausting!
