Canvas Support FAQ
Canvas stretcher bars come together to provide the support over which your canvas prints or paintings are stretched. For best results, look for fully keyable canvas stretcher bars made of straight-grained clear white pine (kiln dried to 8% humidity) and edge-glued and finger jointed to counteract any tendency to warp, with precision tongue & groove joints ensure a perfect friction fit and rigid, square corners.
Stretching your canvas taut over your stretcher frame provides a smooth, tight surface for painting or displaying your prints. Once you’ve stretched your canvas, it’s important to adjust the tension on a regular basis (annually) by keying your stretcher to ensure that it stays taut over time.
A "gallery-wrapped" canvas means that the sides of the canvas are visible when hung and the painting or printed image extends around the sides. These typically use a deeper stretcher frame to make this a design feature. Our 1-½"-deep Gallery stretcher bars are designed as an economical option for this purpose and are suitable for frames 6-60". Larger frames would use one of our heavy duty frame options.

If you’d like to try stretching your canvas by hand, without the pliers, you can certainly do so. Avoid making tugging or jerking movements, and be sure to apply the same tension as you work your way around the stretcher frame. See the blog post DIY Canvas Stretching in 5 Simple Steps [Video] for more.
The most important element in canvas stretching is that you keep consistent tension on the canvas as you work your way around the stretcher frame starting in the center and working out towards the corners. Stapling should proceed in about 12” increments working on opposing sides of the frame to maintain an even stretch across the canvas.
Whatever the shape of your canvas, it’s important that your stretcher frame is constructed of quality material, and that it’s keyable so you can adjust the tension of your canvas over time. Some shapes make a keyable frame impossible, in which case the engineering and construction of the strainer is even more important. You can get canvas in the shape of an oval, circle, triangle, heart, irregular shape or even multi-layered with cut-outs. Explore the possibilities for your shaped canvas support here.
Gallery wrap canvas paintings and print look stunning on their own, as the image literally wraps around the sides. Still, you might decide that you’d prefer to have a frame.
