Round, Oval & Arched Stretcher Frames

Are you looking for a shaped stretcher frame? We make round, oval, and arched frames and, with our CNC technology, we can produce any unusual shapes you can come up with! While most shaped frames are made as strainers (not keyable), we are the only company, to our knowledge, to also fabricate true “keyable” oval or round stretcher frames and canvases. Our shaped supports all come with a front fall or slope to keep the canvas from contacting the frame except at the very edge.

We have made round canvas frames and other shaped stretchers over 19 feet in diameter by laminating plywood sections cut on the CNC machine. The larger frames always include cross-braces for added support and we can supply gravity bars for installation of the canvases.

As in all our products, we guarantee our frames to the highest quality of materials and craftsmanship.

Below are several photos of a variety of shaped frames produced over the past few years. If you would like a quote, please call us at 1-800-561-4944 or email us so we can go over the details of your project. We specialize in custom shapes, small and large, 2D and 3D – so we are happy and confident to tackle any unusual idea you may come up with!

Large frames are made in shaped sections of laminated plywood fastened together with flush-joint connector bolts. This makes it possible to easily disassemble the frame for moving and shipping. We can  supply gravity bars with the frames, providing  a simple way to install the canvas on the wall.

When using shaped frames, we recommend that unprimed cotton or linen canvas be stretched first and then primed. The unprimed canvas is more flexible and can be pulled tight around curved edges without creating folds in the canvas. The photo to the right shows a round canvas stretched on a 60” diameter frame. The visible edge is free of any folds but the folds are quite pronounced on the back side of the frame. The thicker the frame, the more difficult it is to avoid folds in the canvas along the edges. For this reason, we try to keep most frames under 1-1/2” in thickness.


We use CNC machinery to “carve” very precisely any shape you require!




Our oval and round stretcher frames can be disassembled and shipped in a compact, well protected package. This design feature makes it possible to ship large-sized frames by courier at very reasonable prices.

We’ve made a wide variety of arched-top frames, both keyable and fixed designs.
