Short answer: a retractable shade canopy can be fit to almost any pergola, porch or pavilion, but no two structures are the same. Every canopy we sell is built to order, so most of the real work happens before anything is made: measuring, checking where the tracks will mount, and solving whatever makes a structure unusual. Here are five real projects we've worked through with customers, and what each one shows about getting a custom canopy right.

The canopy's tracks mount under the pergola's beams; the fabric slides open and closed along them.
1. A School Pergola in the Adirondacks: Measured by the Facilities Team
A boarding school in Lake Placid, New York, wanted shade over an existing pergola on campus. The opening was an unusual size, 8' by 14'10½", and the school's facilities team planned to install it themselves.
We sent the facilities manager a short video from our production team that shows exactly what to measure. He came back with a drive beam length of 92" and a canopy arm width of 177½". Before anything went into production, we double-checked that his numbers already included the standard clearances: the drive beam is built ½" shorter than the space between the headers, and the canopy arms 1½" narrower. They did, so the canopy was specified to those exact dimensions in a beige Sunbrella fabric.

Measuring the drive beam: it's built ½" shorter than the space between the headers.

Measuring the canopy arm width: the arms are built 1½" narrower than the opening.
Lesson: your own team can measure for a custom canopy. A short video and one double-check of the clearances is usually all it takes.
2. An 18' x 22' Lakeside Pergola: Splitting One Big Span Into Two Canopies
A homeowner with a large pergola between his house and a lake wanted to cover roughly 18' by 22'. The pergola is built from heavy 3x10 beams running from the house out to a 12x8 header on the lake side.
A single canopy that size isn't practical, so we planned it as two canopies, each about 11' by 18.3', running side by side. He sent photos of the beams, and our production team drew up a layout: one drive beam in the center, one near the house, and the existing header on the lake side carrying the far end of the tracks. When he had more questions about the drive beam and side rails, our production team called him directly to go through his options, then sent the exact profile dimensions of the drive beam and guide rails so his handyman could plan the install.

The production team's layout for this pergola: two canopies side by side, a center beam, and guide rails. The drive beam is independent of the headers and gets fastened support every 36" with the included brackets.
Lesson: large spans are usually split into two or more canopies. Send us photos showing which way your beams run, and we'll have a layout drawn for your structure.
3. Porch Rafters Too High for the Rails: Adding a Support Beam
A homeowner in Ohio wanted a canopy that opens and closes toward the house doors. The problem: the porch rafters sit too high and don't come down far enough to hang the guide rails from.
We sent his photos to our production team. Their recommendation was simple: add a beam at the right height to carry the guide rails. That's a straightforward job with lumber from a local hardware store. Our production team then called him to walk through the track measurements so he had everything he needed.
Lesson: if your rafters or beams aren't where the tracks need to be, the usual fix is one added support beam, not a different product.
4. An Oregon Coast Deck With No Overhead Structure Yet
A homeowner on the Oregon coast was building a new 10' x 16' Trex deck and wanted a fabric cover he could open and close, extending about a foot past the deck edge so rain drips off the front.
He sent his deck plans and asked what supports a canopy would need. Because the deck didn't have an overhead structure yet, we looked at it as a pergola and canopy together, so the posts, beams and tracks are planned as one system instead of adapting a canopy to whatever gets built.
Lesson: if you're still building, plan the canopy with the structure. It's the easiest way to get the tracks exactly where they need to be.
5. Landscapers Adding Shade to Their Clients' Pergolas
Many of our canopy requests come from landscape and outdoor construction companies adding shade to pergolas they've built for clients, like a 10' x 12' pergola for a landscaping company in Montana and a new 10' x 13' pergola for a landscaping company in the Dallas area.
For these, we work from the pergola's spec sheet or plans to give a ballpark price quickly, send our measuring video and photos of the system, and confirm the exact measurements, fabric color and freight to the job site once the client approves.
Lesson: if you're a landscaper or contractor, send us your pergola plans and we'll work alongside you and your client.
How We Plan Your Canopy
- Send photos and rough measurements of your pergola, porch or pavilion, or your plans if it isn't built yet. Show which way the beams run.
- We check the fit with our production team and draw up a layout if your structure needs one, including splitting large spans into multiple canopies.
- You measure using our video. We double-check the clearances before anything is built.
- Choose your Sunbrella fabric color. Your canopy is built to order and ships by freight, typically in about 5–6 weeks.
- Install it yourself or with your contractor. Our production team is a phone call away if questions come up.

Bracket depth and clearance are part of the measuring video, so the tracks sit exactly where they need to.
See the Manual Triple-Track Retractable Shade Canopy for sizes, fabrics and pricing, and add matching retractable side curtains to block low sun, wind and views.
FAQ
Can a retractable canopy cover a very large pergola?
Yes. Large spans are usually split into two or more canopies that run side by side, like the 18' x 22' lakeside project above, planned as two canopies of about 11' x 18.3'.
What if my beams or rafters are in the wrong place for the tracks?
The usual fix is adding a support beam at the right height to carry the guide rails. Send us photos and we'll check it with our production team.
How do I measure for a custom canopy?
We send a short video showing exactly what to measure. The drive beam is built ½" shorter than the space between the headers, and the canopy arms 1½" narrower, and we double-check your numbers before anything is built.
Can I install it myself?
Yes. The tracks mount to your beams with standard hardware, so homeowners, facilities teams and contractors can install it themselves, with our production team available by phone for questions.
How long does a custom canopy take?
Each canopy is built to order and typically ships by freight in about 5–6 weeks.
