5x5" Picture Mounts With 3.5x3.5" Aperture

Browse our collection of 5x5" picture mounts with a 3.5x3.5" aperture. It is a compact square format mount that fits inside 5x5" picture frames and presents a 3.5x3.5" image with a neat, even border. This border adds a polished finishing touch to even the smallest display. There is something quietly charming about a well-presented small square frame, and the right mount is what makes that charm feel deliberate. It is a popular choice for miniature prints, small personal photographs, and gifting occasions where a compact but carefully finished display makes a genuine impression. From the delicate warmth of Ivory to the crisp confidence of Ice White, all mount colours are available to help you find the perfect finish.
