15x21 3D Pro Malibu Canvas 2-1/2" #DY-1521

True 7:5 Photography Proportion - 15x21 Size

Another widely used proportion in photography is the 7:5 aspect ratio, but is relatively uncommon in art, save for the 5x7 size. It is commonly accepted as a pleasing proportion. Some artists choose this proportion to add visual interest by breaking away from more traditional shaped canvas sizes. There are only a handful of standard canvas sizes in this ratio, but there are a whole collection of (what we call) Lost Sizes in this aspect ratio, which are often unknown sizes that add intrigue to the final composition.

Explore other sizes in this same 7:5 aspect ratio:

10x14 • 20x28 • 25x35 • 30x42 • 35x49 • 40x56 • 45x63 • 50x70 • 55x77 • 60x84 • 60x84

3D™ Pro 2.5 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 2.5" 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

Solid Wood is Archival - Finger Jointed Wood is Not

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 make are part of the archival process.

The principal reason manufactures use finger jointed wood is reduce cost, not increase archival value. Wood constantly grows and shrinks when the environment becomes hotter, or colder, or more humid, or more dry. Because finger jointed wood is made-up of multiple and varied pieces of wood, with varying grain patterns and densities, they each absorb and shed moisture at varying rates, which works on the glue joints that hold them together, causing the wood to bow and the joints to eventually fail, and certainly not consistent with increasing the archival value of your artwork frame support.

As a manufacturer, we do our part to conserve as much wood as possible, and still provide a quality made product that will out-perform any other in the marketplace.

15x21 2.5" Deep Edge Heavy Frame Offers Maximum Support!

• Drawing depicts the exact frame construction, not the proportion
• 2.5" Deep Edge K2 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
• No Brace Required for this size
• To increase canvas tension, remove any staples in the corners and tap all of the expansion keys further into their respective slots, then tension and re-staple the canvas in the corners

Sustainable Forests for Future Generations

Sustainable forestry practices go beyond just planting and harvesting trees. They also involve careful planning, monitoring, and management to ensure the long-term health and productivity of the forest. By using lumber from sustainably managed forests, we can support these important practices and help to ensure that our planet's forests remain healthy and productive for generations to come.

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.

• 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

3D™ Pro 2.5 Professional canvases are built one-by-one and stretched using our proprietary stretching process called, MuseumWrap™, which relies on in-house custom-built pneumatic machinery that delivers consistently drum-tight stretched canvas, balanced tension across the canvas surface, neatly folded uncut corners, and paintable edges. It is the absolute best way to stretch a canvas.

Time is the wisest counselor of all. ♦ Plutarch

An ancient historian and philosopher, Plutarch often encapsulated profound truths in succinct statements. This adage beautifully articulates the transformative and enlightening power of time. Just as time can erode mountains, it also has the remarkable ability to provide clarity, understanding, and wisdom.

In the world of art, this sentiment holds a special resonance. As we progress in our careers, time becomes both a mentor and a muse. Initial reactions to a piece might be charged with emotions—pride, doubt, elation, or disappointment. But with the passage of time, we gain perspective. A painting once deemed a failure might later reveal lessons that push our boundaries. Similarly, what we once considered our magnum opus might, in retrospect, highlight areas for growth.

By valuing time as a counselor, we learn patience. It encourages us to step back, reflect, and allow our experiences to simmer and mature. This process often leads to deeper insights and a more nuanced understanding of our work. As artists, by surrendering to time, we are often rewarded with its richest lessons, strengthening both our art and our character.

As we honor the legacy of Plutarch, we've created our own portrait as well as pass along these words of wisdom and our take on the message. Get to work on yours!
