15x21 3D Pro Pau Canvas 2-1/2" #DP-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

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

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.

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

Sustainability Promotes Social Well-Being

The forests of the world are a precious resource that must be protected for future generations. By using lumber from sustainably managed forests in our products, we can help to ensure that these valuable resources are preserved and protected. This is not only important for the environment, but also for the social and economic well-being of the communities that rely on these forests for their livelihoods.

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

Since 1965, our passion for perfection has driven us at Masterpiece® to construct professional quality canvases that artists around the nation desire. Your art is better and more valuable when the materials you use are complementary to the blood, sweat, and passion you will paint on top.

Let's go to Tahiti! But not to sketch, we'll go just to be there. ♦ Paul Gauguin

Paul Gauguin's exclamation about Tahiti captures more than just a desire to escape to an exotic location. It embodies a deep yearning to immerse oneself in an environment, to experience it fully, rather than merely observe it from an outsider's perspective. Tahiti, for Gauguin, wasn't just a place; it was a state of mind, an opportunity to be free from societal constraints and to embrace a different way of living and seeing.

We often seek inspiration from the world around us. We travel, we observe, we immerse ourselves in different cultures, hoping to find that spark. Yet, Gauguin's words remind us that sometimes, it's essential to simply be present. Not every experience needs to be captured, sketched, or painted. Some moments are meant just for us, to be felt and lived. In our fast-paced art careers, taking the time to truly immerse ourselves in our surroundings without the pressure of creating can refresh our perspectives and reinvigorate our passion.

We've handpicked this quote and our interpretation of it's meaning to inspire your art. And we honor the legacy of Paul Gauguin by creating this one-of-a-kind portrait to tie it all together. Start Painting!

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.
