40×50cm Picture Mount for 12×18" Artwork

A conservation-grade acid-free picture mount board designed to display 12" × 18" (305 × 457mm) artwork inside a standard 40 × 50 cm frame. The mount creates a balanced border around the artwork, helping the image stand out while protecting it from direct contact with the glazing.

Choose from over 30 mount board colours, ranging from classic framing tones like Snow White, Off White, and Obsidian Black, through to softer neutrals and contemporary colours including sage green, sky blue, blush pink, and rust.

Each mount is precision cut with a slight overlap so the artwork sits securely behind the mount board.

Ideal for framing 12×18" prints, posters, illustrations and photographs in a larger 40×50cm frame.
