15x21 3D Pro Ventura Canvas 2-1/2" #DV-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

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.

When I paint a person, his enemies always find the portrait a good likeness. ♦ Edvard Munch

Edvard Munch, the Norwegian artist best known for his iconic painting The Scream, frequently explored the complex interplay of human emotions, perceptions, and relationships. His works often encapsulated raw feelings, from agony to ecstasy, all captured with intense vividness. Munch's quote here offers a witty observation on human nature, suggesting that when he paints someone, the person's adversaries are more likely to see it as an accurate portrayal, perhaps due to their critical or biased perspectives.

This notion highlights the intriguing challenge we face in representing subjects. As we capture a moment, emotion, or character on canvas, interpretation lies heavily in the eyes of the beholder. Our work becomes a mirror, reflecting not only the subject's essence but also revealing the biases, preconceptions, and emotions of those who view it. Through art, we can expose these biases, prompting introspection and dialogue among our audience. After all, the true magic of art lies not just in its creation, but in its capacity to evoke a myriad of responses and emotions in those who experience it.

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.
