15x21 3D Pro Muir Canvas 2-1/2" #DA-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

Without anxiety and illness, I should have been like a ship without a rudder. ♦ Edvard Munch

Edvard Munch, the renowned Norwegian painter behind the iconic The Scream, often used his art as a cathartic outlet to process his inner turmoil. His life was characterized by a series of personal tragedies, illnesses, and psychological battles that deeply influenced his work. It's a testament to how the challenges faced by an individual can become powerful fuel for artistic expression.

Many of us can relate to Munch's sentiment. The challenges and emotional struggles we face can become central to our artistic identities. They shape our perspectives, add depth to our creations, and often push us towards unparalleled innovation. Instead of seeing these adversities as roadblocks, we can perceive them as crucial guiding forces, much like a rudder to a ship, steering us in directions we might never have ventured otherwise. Embracing our vulnerabilities can lead to the discovery of unique artistic voices and visions that might have remained dormant in more placid times. The message here is clear: the trials we undergo can be the very things that distinguish and define our path in the vast sea of artistic endeavors.

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.
