The Art and Science of Proper Framing

Framing is the final step in presenting artwork to the world, and it has a profound impact on how viewers perceive and value the piece. A well-chosen frame and mat combination enhances the artwork by providing visual breathing room, directing the eye toward the image, and protecting the work from environmental damage. A poorly sized frame, on the other hand, can make even exceptional artwork look amateurish, cramped, or lost within an oversized border. This calculator takes the guesswork out of frame selection by computing the exact frame and mat dimensions needed for any artwork size, ensuring professional presentation every time.

Understanding Mat Borders and Their Visual Effect

The mat, or mount, is the colored border between the artwork and the frame. It serves both aesthetic and practical purposes. Aesthetically, the mat creates a visual buffer that separates the artwork from the frame and the surrounding wall, giving the eye a neutral zone to transition between the art and its environment. A wider mat border makes the artwork feel more precious and gallery-like, while a narrow mat creates a more contemporary, edge-to-edge presentation. Practically, the mat prevents the artwork from touching the glass, which can cause moisture damage, adhesion, and mold growth over time. Standard mat borders range from 2 to 4 inches for most artwork sizes, with the bottom border traditionally made slightly wider than the top and sides to create an optical illusion of centered placement, since perfectly equal borders can appear bottom-heavy to the human eye.

Choosing Frame Sizes for Different Artwork Types

The ideal frame size depends on the artwork's medium, size, and intended display context. Small works on paper, such as watercolors, etchings, and photographs, benefit from generous mat borders that give them visual weight and presence on a wall. A 5x7 inch photograph in a 2.5-inch mat within an 10x12 inch frame feels substantial and intentional. Larger paintings on canvas are often displayed without mats in simple floating frames or gallery wraps that let the artwork extend to the edges. Medium-sized prints and drawings typically use standard frame sizes like 11x14, 16x20, or 18x24 inches with proportional mat borders. When framing for gallery exhibitions, consistency across a series of works creates a cohesive, professional presentation that elevates the entire body of work.

Frame Materials and Conservation Considerations

Beyond dimensions, the materials used in framing significantly affect both the appearance and longevity of the artwork. Acid-free mats and backing boards prevent yellowing and deterioration of paper-based works over decades. UV-protective glass or acrylic glazing blocks harmful ultraviolet light that causes pigments to fade, particularly important for watercolors, photographs, and works on paper displayed in rooms with natural light. Museum-quality framing uses all archival materials and reversible mounting techniques that allow the artwork to be removed without damage in the future. While conservation framing costs more upfront, it protects the value of original artwork and limited edition prints that may appreciate significantly over time, making it a worthwhile investment for any piece you consider important enough to frame.
