24x56 3D Pro 3.5" Deep K3 Stretcher Frame Kit

True 7:3 Extended Domino Proportion - 24x56 Size

This 24x56 is a unique Masterpiece size and 7:3 Extended Domino aspect ratio.

The 7:3 aspect ratio brings a bold and dramatic horizontal stretch, perfect for wide compositions that need to feel expansive and open. This format pulls the eye across the canvas, making it ideal for landscapes, cityscapes, or any scene where horizontal flow is essential. The narrow vertical space adds a layer of complexity, requiring careful use of vertical elements to maintain balance without overwhelming the composition.

There’s a natural tension in this ratio. The wide format invites exploration of the edges, creating a sense of openness, while the limited height keeps the scene intimate and controlled. It’s a format that encourages you to emphasize sweeping gestures, long vistas, or minimalist abstractions. It's great for conveying motion, distance, or the vastness of a scene, all within a strikingly sleek frame.

3D™ Pro 3.5 Stretcher Bar • 1/2" Canvas Clearance

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.

Forests need People, and People Need Forests

Using lumber from sustainably managed forests is a way to support the health and well-being of our planet and its inhabitants. By choosing products made with sustainably sourced lumber, we can help to protect the environment, support local communities, and ensure a sustainable future 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.

34x66 is the Canvas Size Needed for this 24x56 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.

Art must be the cultivation of beauty for beauty's own sake. ♦ Mary Cassatt

Mary Cassatt, a luminary in the realm of Impressionism, was not just a painter but a thinker, continuously exploring the essence and purpose of art. Her proclamation about art's true purpose serves as a reminder of the intrinsic value of beauty. In an era dominated by social conventions and standards, Cassatt's dedication to portraying genuine moments of life made her stand out. She captured the candid beauty of everyday scenes, often emphasizing the intimate bonds between mothers and children.

Today, artists find themselves amidst a whirlwind of trends, technological advancements, and the ever-present allure of commercial success. Yet, Cassatt's words beckon us to remember the heart of our passion. As artists, we must never lose sight of the pure joy of creation and the transformative power of beauty. Art isn't always about the message, the audience, or even the artist; sometimes, it's simply about celebrating beauty in its rawest form. By heeding Cassatt's wisdom, we can ensure that our creative endeavors remain true to the very essence of artistry, enriching not just our careers but our souls as well.
