Mat size for 18x24 print

The first step is to identify the print size (18x24) and then pick a mat opening that fits just inside the image. Aim for even borders and a slight margin so the artwork stays centered. Consider the frame's outer size and how thick you want the border to look; for a balanced display, popular mat widths range from about 1 to 2 inches. If you’re shopping brands like Nielsen-Bainbridge or Crescent, choose a mat board that’s archival and acid-free to protect the print.

The window opening is the most intricate aspect because it determines how the print sits in the mat. Measure the image, then subtract about 1/8 inch from each side to create the opening so the print is secured but not visible on the edges. Center the opening relative to the print so the border looks even on all sides; then choose a mat width that complements the frame and viewing distance. For archival safety, use acid-free mat boards from trusted brands.

Yes—beginners and professionals typically approach mat size differently for an 18x24 print. Beginners typically start with a standard mat opening and a modest border to avoid framing mistakes. Professionals may opt for a precise opening, double matting, or a larger border to emphasize balance and improve display in galleries. Both approaches should center the print and use archival materials, especially for a long-lasting 18x24 presentation.

A simple answer: use acid-free mounting methods and fit the mat to standard frame sizes. Keep the print away from moisture, handle with clean gloves, and clean the glass regularly. Ensure the outer frame can accommodate the mat’s thickness and that the mat opening remains square to the print; brands like Crescent or Nielsen-Bainbridge offer archival mats that resist yellowing over time.

Avoid choosing an opening that is too large or too small for the 18x24 image; this can cause the print to slip or look off-center. Don’t skip archival materials or cheap tape; use corner mounts that are acid-free and reversible. Finally, don't rely on guesswork for border width—measure and preview with a mock-up to ensure the mat enhances, rather than overwhelms, the 18x24 print.
