56x84 3D Pro 3.5" Deep K3 Stretcher Frame Kit

True 3:2 Film Proportion - 56x84 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.

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.

Sustainability Fights Against Climate-Change

Sustainable forestry practices are an important tool in the fight against climate change. By using lumber from sustainably managed forests in our products, we can help to reduce the carbon footprint of our business and support the health of the planet. It's a win-win for everyone involved.

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.

66x94 is the Canvas Size Needed for this 56x84 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.

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.

Nature is the source of all true knowledge. ♦ Leonardo da Vinci

Leonardo da Vinci, often heralded as the quintessential Renaissance man, wasn't just a gifted painter; he was an inventor, anatomist, and a keen observer of the world around him. His insatiable curiosity led him to dissect the intricate details of both the human form and the natural world. His notebooks, teeming with sketches of plants, water currents, and flying machines, show a man striving to unlock the secrets of the universe.

Nature becomes not only a muse but also a teacher. The intricate patterns of a leaf, the play of light on water, or the myriad colors at sunset Ñ all serve as a rich tapestry from which we draw inspiration and knowledge. By observing and engaging with nature, we learn about balance, harmony, and the intricate details that can elevate our art. As we immerse ourselves in the world around us, we find that nature offers lessons not just in artistry but in life itself, urging us to see, to listen, and to understand.
