40 x 40cm Picture Mounts With A3 Aperture

A 40 x 40cm mount with an A3 aperture offers a striking way to display A3 prints in a perfectly square frame. The square outer mount adds balance and symmetry, while the rectangular A3 window creates a bold contrast that draws the eye directly to your print. This format is popular for creating gallery-style arrangements. It mixes square frames with rectangular art to build visual interest on a wall. The mount also provides a protective border, preventing your A3 artwork from touching the glass and preserving its condition. This collection is available in a range of colours. You can opt for a subtle tone to blend with your décor or a statement shade to highlight the details of your artwork.
