70x80 3D Pro 3.5" Deep K3 Stretcher Frame Kit

True 8:7 Near Square Proportion - 70x80 Size

The 8:7 aspect ratio has a subtle horizontal emphasis, providing a slight stretch that offers more width than height. This creates a composition that feels expansive without losing its compactness. The ratio works well for scenes that need a bit of extra breathing room horizontally, such as landscapes, wide portraits, or still life arrangements.

The near-square format adds a sense of balance, while the slight horizontal lean invites the viewer's eye to move side to side, offering gentle movement across the canvas. It’s an ideal choice when looking to create compositions that feel open yet grounded, with enough space to explore without overwhelming the viewer with too much width.

3D™ Pro 3.5 Stretcher Bar • 1/2" Canvas Clearance

1/2" Canvas Clearance is the space between the Bar and the canvas. Generally speaking, more clearance reduces the risk of the canvas touching the wood and creating unsightly lines during painting. Our design provides the optimal clearance so as not to impact your painting, but still leaving enough wood to the maximize strength of the Stretcher Bar.

• 1.25" wide Stretcher Bar
• All Bars have an exclusive groove on the inside perimeter of the frame to which cross braces and Diamond Corner Braces attach

Finger Jointed Wood is not meant for Stretcher Bars

Solid wood makes the most dependable Stretcher Bar, because one homogeneous wood member is going to behave similarly across the entire length of the Bar. Whereas, with finger-jointed wood is made-up of multiple pieces of wood, sometimes on the actual joint itself, presenting multiple points of failure which no one can control.

We only use Solid Wood to build our Stretcher Bars because a solid piece of wood will last indefinitely. When we speak of archival value, it's not just the paint you use and the quality of your canvas and ground, even the wood choices manufacturers add or reduce value to your final painting. The fact is, you don't want problems, and finger joints only increase that risk of the wood falling apart in the future.

The glue used to bind finger joints is a water based adhesive and when that wood is exposed to high humidity environments, particularly with exterior walls, the glue joints can give-up. As a manufacturer, Masterpiece® does its part to conserve as much wood as possible, and still provide a quality product that will out-perform any other in the marketplace.

Sustainable Forests Ensure More Wood for Communities

Using lumber from sustainably managed forests is not only the responsible thing to do, it's also a way to ensure that the wood products we rely on continue to be available in the future. By supporting sustainable forestry practices, we can help to ensure a steady supply of wood products while also protecting the environment and supporting local communities.

Specially Dried and Heat Treated Lumber

We source our wood from a select group of top-tier environmentally conscious lumber mills in the Pacific Northwest. These mills specially dry and heat-treat the lumber to our specifications, resulting in about half the moisture content compared to wood from typical home improvement centers or lumber yards. This process makes the wood stronger, reducing the likelihood of cracking, splitting, or warping. While the wood we use comes at a higher cost, it ensures a more dimensionally stable end product. This stability is crucial for crafting fine professional canvases that support your invaluable art over time.

80x90 is the Canvas Size Needed for this 70x80 Frame

Please note that you will need a canvas that is at least 10 Inches larger than the actual frame size to ensure proper stretching. This will provide ample material to stretch the canvas and attach it to the back of the frame. If you prefer to attach the canvas from the edge of the stretcher frame, you can reduce the size of your canvas by approximately 3/4" all the way around the frame. This will allow you to paint on the edge of the canvas and hang your artwork without needing a separate picture frame. And, if you ever need to remove the canvas from the frame and re-attach it, you'll have enough material to do that too.

With deep family ties and a legacy spanning since 1965 in California, Masterpiece® has been the epitome of unmatched quality in Stretcher Bars across North America. Our commitment to pioneering excellence has crowned us as the forerunners in the world of professional fine-art canvases. Bolstered by our patented innovations, our products exude a caliber that's in a league of its own.

I often think in music. I live my daydreams in music. I see my life in terms of music. ♦ Albrecht Dürer

Albrecht Dürer, while celebrated primarily as a painter, engraver, and printmaker of the Northern Renaissance, had an undeniable depth to his persona. His deep connection to the arts wasn't limited to the visual; it encompassed an expansive emotional and sensory landscape, as evidenced by his profound bond with music. Music, for many, isn't just an art form; it's a language, a lens through which the world is experienced, and for Dürer, it was evidently a vital companion in his creative explorations.

What Dürer highlights here is a sentiment many artists can relate to: the way another art form can influence and shape our primary craft. For artists, we may find our inspiration in dance, literature, or as Dürer did, in music. Such cross-pollination of art forms allows us to view our own work from a fresh perspective, enhancing its depth and richness. It reminds us that art is not siloed but interconnected, and when we open ourselves up to these connections, our work can transcend the boundaries of its medium, resonating with a wider audience.
