Retractable Pergola Canopy Description

Add a retractable pergola canopy to any of our attached or freestanding pergola kits from sizes 12×12 up to 20×20. Infinity Canopy is a slide on wire canopy system that is ready to install out of the box. Canopy kits are manufactured and shipped direct from Infinity Canopy and will be a separate shipment from the pergola kit itself.

Is there more information about canopy colors and fabric?

How are the canopies sized?

The canopy will measure approximately 4 feet less than the pergola size for each dimension; for example, a 12×12 freestanding pergola would receive an 8×8 canopy (inside post to post dimensions) and a 12×12 attached pergola would receive a 10×8 canopy. Another example: a 12×14 freestanding pergola would receive an 8×10 canopy (inside post to post dimensions) and a 12×14 attached pergola would receive a 10×10 canopy.

What if I already have a pergola, do you sell the retractable canopies separately?

If you have or are purchasing a pergola from us and would like to purchase a canopy for your pergola, you can order an Infinity Canopy on our website and we will facilitate the order processing. Infinity Canopy will configure and ship your canopy directly to you.

The canopy sizes listed on our website are built for Pergola Depot pergola kits. If the canopy you’re shopping for is to be attached to a Pergola Depot pergola kit, you can purchase the canopy along with your pergola kit. If you did not purchase your pergola kit from us, we recommend that you order your canopy directly from Infinity Canopy to ensure the proper fit.

For fabric samples and questions specific to the Infinity Retractable canopies, or if you require service after you purchase a canopy, please contact Infinity Canopy directly.
