49x77 3D Pro 3.5" Deep K3 Stretcher Frame Kit

True 11:7 Lucky Numbers Proportion - 49x77 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.

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.

Selective Harvesting in our Sustainable Forests

Intelligent selective harvesting of timber is an ecological method to replace the natural occurrences of forest fires and disease and landslides that can devastate forests. This is all part of the process of sustainable forest management to which we subscribe when we choose which lumber we use in our products.

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.

59x87 is the Canvas Size Needed for this 49x77 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.

Lord, grant that I may always desire more than I can accomplish. ♦ Michelangelo

Throughout history, there have been few artists as prolific and as profoundly influential as Michelangelo Buonarroti. His monumental contributions to art, spanning the awe-inspiring ceiling of the Sistine Chapel to the mesmerizing statue of David, epitomize a ceaseless quest for perfection. Behind his remarkable output was an insatiable thirst for knowledge, growth, and transcendence, eloquently captured in this plea for perpetual aspiration.

In the unpredictable path of art, ambition serves as both the driving force and the north star. While it fuels our creativity and pushes us beyond our boundaries, it also humbles us by showing how much more there is to discover and achieve. Michelangelo, despite his immeasurable achievements, remained grounded in this humility. His works, characterized by their painstaking attention to detail and deep emotional resonance, were the result of an artist who was perpetually in pursuit of the next horizon. His prayer is a reflection of that relentless ambition, a desire to always strive, to always seek, and to never rest on past laurels. It offers a poignant reminder: our greatest accomplishments lie not in the accolades we gather or the masterpieces we create, but in the unending growth and self-discovery. In our shared quest for artistic excellence, let's embrace this spirit, knowing that the horizon, however distant, beckons us ever forward.
