An A3 frame is designed to hold standard A3 artwork, prints, or certificates measuring 29.7 x 42.0 cm (11.69 x 16.54 inches)—exactly double the size of standard A4 paper. It offers an ideal mid-sized display option that provides strong visual impact on residential or commercial walls without dominating smaller spaces. Available in full-bleed formats where the print fills the entire frame or paired with a mat board/mount (typically set inside an A2-sized outer frame), it seamlessly accommodates both modern poster displays and high-end fine art presentations. Built with dual rear hanging hardware for both portrait and landscape orientations, A3 frames are commonly finished in solid wood, slim aluminum, or composite materials, fitted with high-clarity real glass or lightweight, shatterproof acrylic glazing.
