A tool frequently employed in framing, whether by professionals or hobbyists, helps determine the precise dimensions required for a mat based on the artwork’s size and the desired border width. For example, if an artwork measures 8×10 inches and a 2-inch border is desired, this tool will calculate the outer dimensions of the mat, which would be 12×14 inches in this case.
Accurate mat sizing is crucial for a polished and professional framing presentation. Properly sized mats prevent artwork from appearing cramped or lost within the frame, enhancing its visual impact. Historically, matting served primarily as a protective barrier between the artwork and the glazing. Over time, its aesthetic value became recognized, leading to the development of tools that simplify precise calculations. This ensures even borders and a harmonious balance between the artwork and the frame.
