39x63 3D Pro Raw No 12 Canvas 3-1/2" #TR-3963

True Golden Mean Proportion - 39x63 Size

This 39x63 size is one of our Golden Mean sizes, considered the most pleasing shape to the eye!

The Golden Ratio, also known as the Golden Mean or Divine Proportion, is considered the most aesthetically pleasing proportion to the human eye. This proportion has been used in art and architecture for thousands of years, and countless examples can be found in nature, plant life, galaxies, and the human body. The Golden Mean can also be used as a guide to arrange your subjects on the canvas in concert with other Golden Mean shapes like an ellipse, star, triangle, and spiral, resulting in intriguing compositions. Many famous artists, such as Michelangelo, Da Vinci, Mondrian, Botticelli, Dali, and Seurat, have used this proportion in their art, and many contemporary artists continue to use it exclusively. The Golden Ratio can even produce some mathematically intriguing relationships that relate directly to art, architecture, science, and human intrigue. If you're looking for a challenge and inspiration, consider using a canvas in the proportion of the Golden Mean to create a composition that will come alive in the most intriguing ways!

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.

• Produces a 3.5" deep stretched canvas (Actual depth is slightly thinner)
• 1.25" wide Stretcher Bar
• All Bars have an exclusive groove on the inside perimeter of the frame to which cross braces and Diamond Corner Braces attach
• Solid Ponderosa Pine or Fir from the Pacific Northwest

No Finger Joints!

Solid Wood is far superior to finger jointed wood, which is many small pieces glued together, each with varying grain densities that absorb and shed moisture at varying rates, expanding and contracting non-uniformly as environmental conditions change, and causing the wood to bow and the finger joints to eventually fail.

A single homogeneous kiln-dried solid wood Stretcher Bar outperforms and outlasts a finger jointed Bar whose sole purpose is to save the manufacturer cost, not contribute to the archival value of artwork intended to last a millennium. 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.

39x63 3.5" Deep Edge Heavy Frame Offers Maximum Support!

• Drawing depicts the exact frame construction, not the proportion
• 3.5" Deep Edge K3 Heavy Stretcher Bars are precision machined with a unique double tongue-and-groove corner joint that provides rock-solid torsional rigidity that resists warping or twisting, which is an important benefit for such a deep edge canvas
• Two super strong 3/4" thick keyable braces and two cross braces (all 3.25" wide) provide the maximum possible support for this 39x63 frame; Cross Braces are permanently installed in the frame, but canvas tension may be increased by tapping-in the keys or wedges that slightly expand the size of the frame
• The Stretcher Bars have an proprietary utility groove on the inside perimeter of the frame which is used to attach braces and other optional frame supports
• The Masterpiece braces feature an exclusive system that allows you to increase the tension to the middle of the frame, where the tension is needed the most; it's so unique it earned us a patent
• Our state-of-the-art cross braces attach the ends of the cross braces into the (grooved) sides of the braces, which creates a superior and robust system of interlocking cross braces
• To increase canvas tension: 1) remove any staples in the corners and those that retain the brace keys in the middle, 2) tap all of the expansion keys further into their respective slots, 3) tighten and re-staple the canvas in the corners

Canvas Tension is in Your Control

In dry climates or air conditioned environments, the lack of moisture in the air causes wood frames to shrink and the canvas fibers to narrow and elongate making the canvas more slack and resulting in a loss of canvas tension. In some instances, the canvas could have waves on the surface resulting in an unsightly viewing experience.

Our 3D™ Pro 3.5 professional frames provide the functionality for you to slightly expand the size of the frame in the corners and the middle of the canvas, thereby increasing canvas tension all across the surface. The difference between a loose canvas and a tight canvas is just 1/8" of an inch, so a small adjustment using our corner and brace keys makes an important difference in canvas tension.

• Helps to prevent waves that occur in a loose canvas
• Increase canvas tension by tapping-in the corner and brace keys
• True professional class canvases make it possible for you to adjust the canvas tension

Cross Braces Make it Tighter

A tightly stretched canvas on an un-braced frame overpowers the Stretcher Bars causing them to bow inward and thereby lose tension. Sometimes that bow can expose a space in picture frames.

When a canvas is stretched on a properly supported frame, the cross-braces prevent the Bars from bowing thereby achieving maximum canvas tension. To increase the canvas tension even more, simply tap the corner and brace keys further in their slots. Properly supported frames provide you with the control over the canvas tension of your canvas and painting.

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

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.

MuseumWrap™ Stretching Technique

With more than a half a century of American engineering, Masterpiece® designs and builds its own proprietary stretching equipment that enables us to produce the finest and most tightly-stretched canvas on the market.

• Drum-tight stretch!
• Up to 50% tighter than other methods
• Balanced tension across the surface
• Uncut folded corners make it possible to remove and re-stretch canvas on the same size frame
• Usually the corner folds are on the long sides

I could paint for a hundred years, a thousand years without stopping and I would still feel as though I knew nothing. ♦ Paul Cézanne

A post-impressionist painter, Paul Cézanne stood at the confluence of the 19th century's artistic traditions and the avant-garde movements that would shape the 20th century's art world. Yet, despite his immense contributions to the realm of art, Cézanne remained humble, introspective, and ever-curious.

This confession of his boundless quest for knowledge and understanding resonates deeply. The vast landscape of artistic expression is one where we often find that the more we learn and grow, the more we realize there's so much left undiscovered. For artists, the path is characterized by perpetual learning, experimentation, and evolution. Each canvas, each stroke is but a momentary pause in a continuous flow of creativity and exploration.

His words remind us that the joy of art doesn't reside in mastery alone, but in the eternal journey of discovery and growth. The beauty of our craft is in its infinite nature. There's always a new technique to explore, a new emotion to capture, a new perspective to consider. It's a humbling experience, but also a deeply rewarding one. It's this insatiable curiosity and hunger to learn that fuels our creativity and drives us to paint yet another canvas, even when we feel we've only just begun.
