True Dynamic Root-5 Proportion - 21x47 Size
This 21x47 is one of our Dynamic Root-5 Rectangle Root-5 Rectangle series.
The Dynamic Root-5 rectangle is an inspiring proportion based on organizing your spatial composition with endless symmetrical divisions. The premise in Jay Hambridge's 1926 book is that the Dynamic Symmetry of individual elements are informed by their relationship to the entire composition. This very special proportion is guided by the square roots of integers and has a storied and historical basis in art.
It involves the use of geometric shapes and patterns in the proportion of the square root of 5 to 1 to create balance and harmony in a composition. This can be achieved by dividing a composition into a grid of squares or rectangles, and then placing elements within the grid in a way that follows the principles of dynamic symmetry. Dynamic symmetry is often used to create a sense of order and structure in a composition, and can be particularly useful for creating compositions that are harmonious and pleasing to the eye.

Elite™ Professional 1.5" Deep B2 Bar • 1/2" Canvas Clearance
A Canvas Clearance of 1/2" 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.
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.

Biodiversity in our Forests is the Key to Life as we know it
By using lumber from sustainably managed forests in our products, we can ensure that the forests will continue to thrive and provide valuable resources for years to come. Sustainable forestry practices help to maintain the health and biodiversity of the forest, which benefits not only the environment, but also the local communities and businesses that rely on the forest for their livelihoods.
Specially Dried and Heat Treated Lumber
Our wood is handpicked from a curated group of environmentally responsible lumber mills in the Pacific Northwest. By adhering to our precise drying and heat-treatment standards, these mills produce lumber with nearly half the moisture you'd find in common home improvement outlets or lumber yards. This meticulous process not only enhances the wood's strength—minimizing risks of cracks, splits, or bends—but also elevates its dimensional stability. Such quality, despite its premium, is paramount in creating professional canvases designed to uphold the sanctity of your cherished art throughout the years.
27x53 is the Canvas Size Needed for this 21x47 Frame
Please note that you will need a canvas that is at least 6 Inches larger than the actual frame size to ensure proper stretching. This will provide ample material to stretch the canvas and attach it to the back of the frame. If you prefer to attach the canvas from the edge of the stretcher frame, you can reduce the size of your canvas by approximately 3/4" all the way around the frame. This will allow you to paint on the edge of the canvas and hang your artwork without needing a separate picture frame. And, if you ever need to remove the canvas from the frame and re-attach it, you'll have enough material to do that too.

The chief function of color should be to serve expression.
♦ Robert Delaunay
Robert Delaunay's career was distinguished by a passionate exploration of color and its powerful ability to convey emotions and ideas. His belief in the emotive potency of color wasn't just a fleeting thought; it was the bedrock upon which his artistic innovations stood. For Delaunay, color was more than mere aesthetic—it was a language, a form of communication that transcended words.
Artists often find themselves at crossroads, questioning the role of various elements in their creations. What should be the driving force? Technique, form, or color? But, for Delaunay, it was clear. He saw color as a servant to expression. Just as a writer selects words with precision to evoke certain feelings or images, artists choose shades and hues to manifest their innermost thoughts and emotions on canvas. We wield our palettes, not just to beautify, but to communicate, to give voice to our inner landscapes.
So, while selecting hues for our next masterpiece, let's remember Delaunay's wisdom. Let us not be overwhelmed by the myriad of choices but choose with intention. For in the dance of colors, it's the emotion and expression that take the lead, guiding us to produce art that speaks, resonates, and moves the soul.
Creativity is a dance between inspiration and innovation. Our own self portrait creation of Robert Delaunay twirls alongside these profound words, hoping to set the stage for your next artistic performance. Now go do your dance on the canvas!
