37x60 3D Pro 3.5" Deep K3 Stretcher Frame Kit

True Golden Mean Proportion - 37x60 Size

This 37x60 size is one of our Golden Mean sizes, considered the most pleasing shape to the eye!

The Golden Ratio, also known as the Golden Mean or Divine Proportion, is considered the most aesthetically pleasing proportion to the human eye. Used in art and architecture for thousands of years, countless examples can be found in nature, plant life, galaxies, and the human body. It is often used as a guide to arrange your subjects on the canvas in concert with other Golden Mean shapes like an ellipse, star, triangle, and spiral, resulting in intriguing compositions. Many famous artists, such as Michelangelo, Da Vinci, Mondrian, Botticelli, Dali, and Seurat, have used this proportion in their art, and many contemporary artists continue to use it exclusively. If you're looking for a challenge or some inspiration, consider using a canvas in the proportion of the Golden Mean to create compositions that come alive in the most intriguing and eye-catching ways!

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.

Solid Wood is Archival - Finger Jointed Wood is Not

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 make are part of the archival process.

The principal reason manufactures use finger jointed wood is reduce cost, not increase archival value. Wood constantly grows and shrinks when the environment becomes hotter, or colder, or more humid, or more dry. Because finger jointed wood is made-up of multiple and varied pieces of wood, with varying grain patterns and densities, they each absorb and shed moisture at varying rates, which works on the glue joints that hold them together, causing the wood to bow and the joints to eventually fail, and certainly not consistent with increasing the archival value of your artwork frame support.

As a manufacturer, we do our part to conserve as much wood as possible, and still provide a quality made product that will out-perform any other in the marketplace.

Sustainably Managed Forests

We use lumber grown in the sustainable forests of the Oregon, Washington, and California, where there’s more standing timber today than last century! Our forests purify the air, provide oxygen, and reduce global warming. More trees are needed on this planet, not fewer. Therefore, we use lumber grown in responsibly managed forests, so future generations can benefit from our collective responsible actions today.

Specially Dried and Heat Treated Lumber

Our wood is handpicked from a curated group of environmentally responsible lumber mills in the Pacific Northwest. By adhering to our precise drying and heat-treatment standards, these mills produce lumber with nearly half the moisture you'd find in common home improvement outlets or lumber yards. This meticulous process not only enhances the wood's strength—minimizing risks of cracks, splits, or bends—but also elevates its dimensional stability. Such quality, despite its premium, is paramount in creating professional canvases designed to uphold the sanctity of your cherished art throughout the years.

47x70 is the Canvas Size Needed for this 37x60 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.

Don't wait for the muse; she's already within you. ♦ Paul Gauguin

Paul Gauguin's pursuit of artistic inspiration took him to distant lands, but it was always rooted in a deeper understanding that true creativity originates from within. Moving from metropolitan Paris to the exotic shores of Tahiti, he sought external landscapes, but it was the internal landscape of his soul that informed his most memorable works.

Similarly, in our paths as artists, we might look for external stimulants, hoping for that spark of inspiration. Whether it's a new location, a fresh set of colors, or a different medium, it's easy to believe that the next breakthrough is just one more tool away. But Gauguin's words offer a gentle reminder: the muse we seek is not outside but within us. Our experiences, our emotions, our memories—they are the fuel for our artistic fire. Recognizing and harnessing that internal power can transform our work in profound ways.
