The KGD print measures 102mm x 136mm, or approximately 4 inches wide by 5.4 inches tall, resulting in a modest surface area of 55 square inches. The proportions give it an aspect ratio close to 4:5. Falling between 2R and 4R in size, KGD classifies among small print formats. Its origins trace back to the Kodak General Document format introduced in the 1980s for business document printing needs. The abbreviation KGD comes from Kodak General Document. While intended for text printing, the size was also adapted to small photograph prints. Today, KGD fills a niche for compact photo output at a budget price. The modest 4:5 ratio accommodates both vertical and horizontal crops. While image quality is understandably limited by the size, KGD prints remain useful for snapshots, contact sheets, and other applications where tiny economical prints suffice. For cost-effective small photo output, the KGD format hits a versatile sweet spot.
