3/4″ Gallery Wrap Stretched Canvases

Unlike economy-grade stretched canvases found in art supply stores, Upper Canada Stretchers “Gallery Wrapped” Stretched Canvases are a premium, professional-quality product. Using our 3/4″ (20mm)-thick stretcher bars in either the BASIC or STANDARD profile (depending on the frame size ordered) and paired with our 1/2″ x 3″ bracing where necessary, these frames are fully keyable, allowing the canvas to be properly stretched and adjusted over time to keep the ideal tension. The back-stapled #12 cotton duck canvas (approx. 17 oz/sq yd after priming) has a tighter weave and higher thread count than economy-grade canvas and is double-primed with professional quality acrylic gesso to provide an excellent starting point for your paintings. All Upper Canada Stretchers stretched canvases come already keyed and ready for you to paint but keys can be further adjusted, as necessary.

3/4” Gallery Wrap Stretched Canvases can be ordered in both imperial and metric sizing in any dimension from 6-36″/16-92cm (accurate to 1/16” or 1mm) using the custom calculator below – recommended bracing will be calculated automatically but can be increased if you wish.
