30x45 3D Professional 2.5" Deep K2 Stretcher Frame Kit

True 3:2 Film Proportion - 30x45 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.

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.

Selective Harvesting in our Sustainable Forests

Intelligent selective harvesting of timber is an ecological method to replace the natural occurrences of forest fires and disease and landslides that can devastate forests. This is all part of the process of sustainable forest management to which we subscribe when we choose which lumber we use in our products.

Specially Dried and Heat Treated Lumber

We source our wood from a select group of top-tier environmentally conscious lumber mills in the Pacific Northwest. These mills specially dry and heat-treat the lumber to our specifications, resulting in about half the moisture content compared to wood from typical home improvement centers or lumber yards. This process makes the wood stronger, reducing the likelihood of cracking, splitting, or warping. While the wood we use comes at a higher cost, it ensures a more dimensionally stable end product. This stability is crucial for crafting fine professional canvases that support your invaluable art over time.

38x53 is the Canvas Size Needed for this 30x45 Frame

Please note that you will need a canvas that is at least 8 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.

Tight'n'Up™ Liquid Canvas Retensioner

One of our most appreciated products helps make your canvas tighter! Stretching a canvas tightly can be a challenge. Our Frame Kits include the Corner and Brace Keys that you will need to add tension, but Tight'n'Up™ Liquid Canvas Re-Tensioner is a way that you can use to add tension to the canvas without needed to use the keys. It canvas 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. Recommended for acrylic primed cotton or linen canvas. We do not recommend it for oil primed canvas because there are simply too many different types of oil primed canvas, but used conservatively at your own risk, it will tension any canvas.

In art, the hand can never execute anything higher than the heart can imagine. ♦ Ralph Waldo Emerson

Ralph Waldo Emerson, a philosopher and poet whose words have echoed through the ages, often delved into the interplay between human potential and inner conviction. His perspective on life, nature, and self-reliance has not only characterized his own writings but has also left an indelible mark on American thought and literature.

Artists find this sentiment particularly compelling. Every creation begins as a spark, a vision nurtured within the heart before it takes form in the external world. The power of our imagination, fueled by emotions and experiences, sets the bar for what we bring forth into reality. It's a reminder that our capacity to create is intrinsically tied to the depth of our emotional and spiritual experiences. For us, it's not just about mastering the technical aspects but also about plunging into the depths of our souls to bring forth visions that were previously intangible. In acknowledging this truth, we celebrate the boundless landscape of our inner world, understanding that its vastness determines the heights our art can reach.
