Matte canvas refers to a canvas material with a non-glossy finish. Unlike glossy canvas, which reflects light, matte canvas has a flat surface that minimizes glare, making it suitable for displaying artworks in various lighting conditions without distracting reflection .The "1.25" measurement refers to the thickness or depth of the wooden stretcher bars used for the frame. In this case, the bars are 1.25 inches thick. Thicker stretcher bars provide more depth to the artwork when hung on a wall, creating a sense of dimensionality and presence. Stretched canvas means that the canvas has been tightly stretched andsecured across a wooden frame, usually made of kiln-dried stretcher bars. This process ensures that the canvas remains taut and smooth, providing a stable surface for painting or printing.
