58x87 3D Pro 3.5" Deep K3 Stretcher Frame Kit

True 3:2 Film Proportion - 58x87 Size

The 3:2 aspect ratio is a very familiar format film, computer screens, and video, and, of course, is an aesthetically appealing proportion for your artistic compositions. Most 35 mm film cameras are based on this exact proportion, so our brains are trained to see images in this same ratio. It is commonly used for landscape photography and artwork, as it allows for a wide, panoramic view of the scene. It can be used to create a sense of balance and harmony in the composition, providing depth and perspective, as the longer sides of the canvas allow for more space to depict the background or foreground elements of the scene.

Even though this proportion is widely used, there are only a handful of commonly available standard canvas sizes in this ratio. There are a whole collection of intriguing (what we call) Lost Sizes, which are uncommon sizes in this common proportion. Unusual canvas sizes add intrigue to your artwork and an additional story to tell about your painting.

3D™ Pro 3.5 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.

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.

What is Sustainable Forestry?

To a forester, the term "sustainable" could mean exercising industry adopted forestry practices to maintain a forest indefinitely. To a logger, the process of proper care for the trees remaining after a harvest. To a landowner, their interest may lie in keeping their forest in the family. And to those of involved in the process of making and using wood-based art supplies, it can mean promoting and supporting an industry dedicated to the preservation of our precious natural resource. We can all do our part to care for our national forests.

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.

68x97 is the Canvas Size Needed for this 58x87 Frame

Please note that you will need a canvas that is at least 10 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.

I can't paint the way they want me to paint, and they know that too. ♦ Rembrandt van Rijn

One of the greatest painters in European art history, Rembrandt van Rijn stood firm in his unique artistic style despite external pressures. Living during the Dutch Golden Age, a time characterized by dramatic shifts in art and society, Rembrandt encountered both admiration and criticism. This declaration of artistic independence exemplifies the spirit of many artists who, at some point in their careers, face the challenge of balancing their unique vision with societal or commercial expectations.

Such a sentiment is not unfamiliar to artists. We often face a world full of expectations, guidelines, and unsolicited advice. But true artistic innovation often requires deviation from the norm, a courage to swim against the tide. By reflecting on Rembrandt's words, we are reminded of the importance of staying true to our vision. For in authenticity, our art finds its most profound voice.
