With dimensions of 20 inches wide by 30 inches tall, the 20" x 30" print size has an expansive surface area of 600 square inches and a 2:3 aspect ratio. In the metric system, it corresponds to 508mm x 762mm. The ultra-large 20" x 30" size dwarfs standard sizes like 8"x10" and 16"x20". It sits among the grandest of premium extra-large print sizes. The origins of 20" x 30" lie in large format panoramic film photography. Its substantial length allowed for sweeping landscape images. Today, 20" x 30" endures as a premier choice for photographic fine art prints of landscapes and other wide compositions. The ability to print panoramic digital photos at 20" x 30" has also contributed to its lasting popularity. At this enormous size, prints command attention on walls and as artistic pieces. However, costs are high due to the amount of material required. Photographers who demand the ultimate in print impact and resolution will find the classic "two by three" aspect ratio of 20" x 30" ideal for displaying their best work in large-scale fine art reproductions.
