12×18" Picture Mount for 20×30cm Artwork

A conservation-grade acid-free picture mount board designed to display 20 × 30 cm artwork inside a standard 12" × 18" (305 × 457mm) 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 20×30cm prints, posters, illustrations and photographs in a larger 12×18" frame.
