20X40 3D Pro Muir Canvas 3-1/2" #TA-2040

True 2:1 Domino Proportion - 20X40 Size

20x40 is one of our popular Domino 2:1 sizes.

The 2:1 aspect ratio, that we call the domino proportion, also offers a unique canvas for artists to play with the perception of space and depth within their compositions. The elongated format allows for the inclusion of foreground, middle ground, and background elements, creating a sense of distance and scale that draws the viewer's eye into the artwork. This aspect ratio has been used by artists throughout history, from ancient Egyptian tomb paintings to Renaissance frescoes to contemporary photography. Its versatility and timelessness make it a classic choice for artists seeking to create dynamic and engaging compositions.

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.

20X40 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
• One super strong 3/4" thick keyable brace provides maximum possible support for this 20X40 frame - Brace is 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 brace feature an exclusive system that allows you to increase the tension to the middle of the canvas, where the tension is needed the most; it's so unique it earned us a patent
• 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.

Sustainably Managed Forests Coexist with Mankind

We use lumber grown in the sustainable forests of the Pacific Northwest, where thereÕs more standing timber today than last century! There will always be a demand for wood pulp and fiber, but striking a harmonious balance with human coexistence is the essential strategy to which we subscribe. Sustainably managed forests increase our health and abundance of our forests which can be in harmony with this precious natural resource.

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.

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

The canvas you select becomes the foundation of your painting and will forever be, so choose your substrates wisely. Savvy art buyers and art enthusiasts place a higher value on artwork made with quality materials because they expect their investment in your art will be a lasting testament to your brand and legacy.

I dream my painting and I paint my dream. ♦ Vincent van Gogh

Van Gogh, with his passionate brush strokes and turbulent life, has always been a source of fascination. This sentiment he expressed feels almost like a secret window into his soul. For Vincent, the line between dream and reality often seemed blurred. He grappled with his own mind, a tempest of emotions, and found solace in the vivid colors and swirling patterns of his art. Is it not a dance that many artists are familiar with? As we stand before our canvas, the thoughts and emotions within us spill onto it, turning our abstract dreams into tangible masterpieces.

But it's not always about grand visions. Sometimes it's the little dreams, the fleeting daydreams, that find their way into our creations. The shade of a sunset we once dreamt of, or the curve of a smile from a fading memory. Van Gogh's words remind us that the dreams we paint aren't just fantasies; they're a slice of our soul, immortalized in color. It's a bit magical, isn't it? At times, we artists can't quite tell if we're dreaming or awake. But that's the beauty of it. Every brushstroke is a dream, and with it, we share a piece of our world.

Tight'n'Up™ Liquid Canvas Retensioner

While all of our Masterpiece® Pro canvases are stretched very tightly and our frames have a built-in method to increase tension, we have another method to add canvas tension. Tight'n'Up™ Liquid Canvas Retensioner (sold separately) can be sprayed on the back of a canvas to repair most canvas tension issues.

With Tight'n'Up™, you can add tension to just a small area, or a large area. Simply spray it lightly on the back and brush it into the canvas, and within seconds, your canvas becomes tighter and stays tighter. The more you use, the tighter it gets.
