A border around a painting is typically referred to as a "mat" or "matting." This is a decorative layer often made of paper or cardboard that surrounds the artwork, providing a visual separation between the painting and its frame. The mat enhances the presentation and can also protect the artwork from damage. In some contexts, the term "frame" may also refer to the entire border and support structure surrounding the artwork.
