28x44 3D Pro 3.5" Deep K3 Stretcher Frame Kit

True 11:7 Lucky Numbers Proportion - 28x44 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.

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.

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 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.

38x54 is the Canvas Size Needed for this 28x44 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.

I am not interested in the money but the joy of my paintings being seen by everyone. ♦ Frida Kahlo

Frida Kahlo's legacy is not just in her iconic self-portraits or vibrant colors but in her unwavering devotion to art's true essence. Rather than commercial gains, Kahlo's heart yearned for her work to touch lives, evoke emotions, and stir souls. In a world where value is often equated with monetary worth, as artists, we too aspire for our work to transcend material confines, seeking joy in the shared experience of art, the communal resonance of our creations.

Kahlo's words serve as a timely reminder to us all about art's core values. In a realm dominated by financial pursuits, it's easy to lose sight of the pure elation stemming from genuine artistic connection. Drawing from Kahlo's perspective, we are encouraged to remain rooted in authenticity, cherishing the immeasurable satisfaction that arises when our art bridges souls, echoing shared human experiences.
