The 6x6 medium format print measures approximately 60mm x 60mm, or about 2.4 inches square. This creates a modest square print area of 36 square inches. As its name denotes, 6x6 originated from 120 medium format film in 6x6cm cameras, which yielded 2.4 inch square negatives. Introduced in the 1930s, the square 6x6cm size set the standard for medium format photography for decades thanks to its versatility. Today, 6x6 remains valued by photographers for its balanced square composition and exceptional image quality from medium format films and digital backs. It lends artistic options without committing to large printing costs. The 1:1 format also stands apart from common rectangular aspect ratios. For professional photographers, 6x6 endures as the classic versatile square medium format print size that set the standard for 120 film cameras. It continues offering an expressive creative outlet at modest sizes.
