20x48 3D Professional 2.5" Deep K2 Stretcher Frame Kit

True 12:5 Extended Domino Proportion - 20x48 Size

This 20x48 is a unique Masterpiece size and 12:5 Extended Domino aspect ratio.

This wide and expansive format is perfect for compositions with a strong horizontal flow. Its elongated shape encourages the eye to move across the canvas, making it ideal for landscapes, panoramic scenes, or compositions where you want to emphasize movement or space. It creates a sense of openness without overwhelming the viewer. It allows for more complex or extended narratives within a single frame while maintaining balance and proportion.

The vertical dimension is still significant enough to avoid feeling overly compressed, giving artists the opportunity to play with both horizontal and vertical elements in a broad yet contained space. It works especially well when you want to stretch a scene or subject providing room for exploration while still keeping the composition grounded. It invites expansive storytelling or sweeping visuals, all within a sleek, visually striking format.

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.

Sustainably Managed Forests Inhale and Exhale

The world's forests are essential to human survival. Forests inhale carbon dioxide for the earth, and exhale oxygen essential for life. When we speak of the sustainable forest strategy of ensuring that more timber will exist in the same forest land than exists today, this is the only viable plan for the future of humanity. For this reason, we use only lumber from the sustainable forests of Oregon, Washington, and California, where there’s more standing timber today than last century!

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.

28x56 is the Canvas Size Needed for this 20x48 Frame

Please note that you will need a canvas that is at least 8 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.

One must see one's model correctly and experience it in the right way, and furthermore express oneself forcibly and with distinction. ♦ Paul Cézanne

Paul Cézanne, a post-impressionist master, stood at a crucial intersection of 19th-century Impressionism and the foray into the abstraction that would characterize the 20th century. His unique approach to form and color was transformative, and he believed in both the fidelity to the natural world and the artist's subjective experience of it. In an era where artists were pushing boundaries, Cézanne advocated for a careful and considered approach to representation.

His emphasis on seeing one's model correctly speaks to the importance of truly understanding and internalizing what stands before the artist. It isn't just about replication, but about interpretation. In the world of art, where myriad styles and techniques beckon, we are reminded to be true to our perceptions and emotions, to portray not just what we see but how we feel. Cézanne challenges us, as artists, to not just depict but to distinguish, ensuring our works carry a unique signature, a personal touch that separates them from the rest.
