The size of a mat, in the context of picture framing, refers to its outer dimensions, which are designed to be the same as the picture frame size it fits into. Essentially, a mat's stated size (e.g., 16x20) indicates the dimensions of the frame opening (or the glass size from the back side of the frame) it will perfectly fill.
Understanding Mat Dimensions
When you purchase a mat, its listed size defines its external measurements, ensuring it fits snugly within a corresponding frame. For instance, a 16x20 Mat is designed to fit seamlessly into a 16x20 picture frame.
It's important to distinguish between the mat's outer dimensions and its inner opening (or aperture). The inner opening is the cut-out section where your artwork or photograph will be displayed. This opening is typically slightly smaller than your artwork to provide an overlap, preventing the art from falling through and ensuring a clean border.
- Outer Dimension: This is the overall size of the mat board, matching the interior dimensions of the picture frame or the glass size.
- Inner Opening (Aperture): This is the window cut into the mat, through which your artwork or photograph is viewed. It is usually cut to be slightly smaller than the artwork itself to create a secure overlap.
Common Mat Sizes and Their Applications
Mats are crucial for enhancing artwork, providing a visual border, and protecting the piece by keeping it separated from the frame's glass. While smaller photos, such as 3x5 or 4x6, might sometimes be framed without a mat, using one can significantly elevate their presentation. For example, a 4x6 photo can fit nicely into a 5x7 Mat, meaning the mat's outer dimensions are 5x7, and its opening is suitable for a 4x6 print.
Here's a table of common mat sizes and their typical uses:
| Mat Size | Fits Frame Size | Fits Photo/Artwork Size (Common Opening) | Notes |
|---|---|---|---|
| 5x7 | 5x7 | 4x6 | Ideal for small portraits and personal photographs. |
| 8x10 | 8x10 | 5x7, 4x6 | Popular for standard photo prints and smaller art pieces. |
| 11x14 | 11x14 | 8x10, 5x7 | Versatile for medium-sized prints, documents, and certificates. |
| 16x20 | 16x20 | 11x14, 8x10, 5x7 | Frequently used for larger photographs, art prints, and posters. |
| 20x24 | 20x24 | 16x20, 11x14 | Great for displaying significant artworks or large-format photographs. |
Why Mat Size Matters
Choosing the correct mat size is essential for several reasons:
- Aesthetic Enhancement: A well-chosen mat provides a visual breathing room around the artwork, drawing the viewer's eye towards the subject. It can dramatically enhance the artwork's presentation and perceived value.
- Protection: Mats create a physical barrier between your artwork and the frame's glass. This prevents the artwork from sticking to the glass, which can cause damage over time due to moisture or condensation. This is particularly important for photographs and delicate mediums.
- Standardization for Framing: By matching the mat size to standard frame sizes, it simplifies the framing process, making it easier to find off-the-shelf frames.
Choosing the Right Mat Size
When selecting a mat, consider these practical steps:
- Determine Your Frame Size: If you already have a frame, the mat's outer dimension must match the frame's inner dimensions precisely.
- Measure Your Artwork: Know the exact dimensions of the photo or art piece you wish to display.
- Consider Border Width: Decide how wide you want the mat border to be around your artwork. A wider border often adds a sense of importance and elegance. The inner opening will then be cut accordingly, typically slightly smaller than the artwork to create a secure overlap.
Custom Matting vs. Standard Sizes
While standard mat sizes are widely available and cost-effective, custom matting offers tailored solutions for unique artwork dimensions or specific aesthetic preferences. Custom mats allow for precise control over border widths, colors, and textures, providing a perfect fit and finish for any piece.
