56x88 3D Pro 3.5" Deep K3 Stretcher Frame Kit

True 11:7 Lucky Numbers Proportion - 56x88 Size

The 11:7 aspect ratio creates a distinct horizontal emphasis while still maintaining enough height for vertical elements to play a role. The width invites a natural flow across the canvas, making it perfect for landscapes, narrative scenes, or compositions that stretch laterally but still need that vertical grounding.

The ratio’s off-balance, slightly stretched feel adds tension, making compositions feel dynamic without being overwhelming. The 11:7 proportion encourages exploration of movement and space, allowing subjects to breathe while still offering enough height to create depth and contrast. The fact that it combines lucky numbers, 7 and 11, adds an extra layer of appeal, bringing both an artistic and symbolic charm to the canvas. It’s a format that balances horizontal exploration with just enough verticality to keep the viewer engaged.

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.

Sustainable Forests for Future Generations

Sustainable forestry practices go beyond just planting and harvesting trees. They also involve careful planning, monitoring, and management to ensure the long-term health and productivity of the forest. By using lumber from sustainably managed forests, we can support these important practices and help to ensure that our planet's forests remain healthy and productive for generations to come.

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.

66x98 is the Canvas Size Needed for this 56x88 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.

Beauty in art is the delicious notes of color one against the other. It is just as much system as the solar system. ♦ George Inness

In the eyes of George Inness, the interplay of colors in a piece of art is not a random act of whimsy but a systematic dance, echoing the precision and beauty of celestial bodies in motion. Inness, renowned for his atmospheric landscapes, knew the profound impact that juxtaposing just the right hues could have on a canvas. The seemingly effortless placement of one shade against another is a culmination of observation, understanding, and an intrinsic feel for the natural world.

Just as the planets revolve in a predetermined path, governed by gravitational forces, the colors in an artwork too have their own gravity, their own pull. When harmonized correctly, they strike a balance that feels both organic and preordained. For us, as creators, this serves as a reminder. While our instincts guide our hand, understanding the science behind our choices, the very system that makes a composition sing, is crucial. Just as astronomers look to the stars and see patterns, we must find our patterns in the palettes we choose, crafting artworks that not only please the eye but also resonate with the very rhythm of the universe.
