15x21 3D Pro Poitiers Canvas 2-1/2" #DQ-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.

• 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.

In the symphony of art, every artist plays a unique note. ♦ Paul Gauguin

Paul Gauguin, known for his bold use of color and innovative techniques, distinguished himself from his contemporaries in more ways than one. Venturing far from Europe's familiar terrains, he sought inspiration in the remote landscapes of Tahiti and the Marquesas Islands. There, amidst the untouched beauty and native cultures, he found a unique voice, a note distinct from the cacophony of the European art scene.

It's a testament to the idea that every artist, no matter the medium or background, brings something irreplaceable to the table. Like instruments in an orchestra, each of us contributes to the larger composition of the art world. While some may play loud and with fervor, others might offer soft, subtle undertones. The beauty lies not in the volume or the prominence of the note but in its authenticity. For it's through this authenticity that we, as artists, leave an indelible mark on the canvas of history.
