Our A3 picture mounts are designed for standard A3 frames (297 × 420 mm), creating a clean border around artwork while separating it from the glazing for a more refined presentation.

Cut from conservation-grade acid-free mount board and available in 30+ colours, they're ideal for framing prints, posters, photographs and illustrations.

Manufactured and assembled in the United Kingdom.
