In the metric system, it equates to 762mm x 1016mm. The super-large 30" x 40" size dwarfs even prints like 24"x36" and 20"x30". It sits among the grandest of premium oversize photographic prints. The origins of 30" x 40" trace to large format film photography used for massive photographic art reproductions. Its substantial height allowed for life-size portrait prints. Today, 30" x 40" endures as an elite choice for photographic fine art prints of portraits, landscapes, and any images warranting an extravagant large-scale presentation. At this enormous size, the prints command attention and convey an imposing presence when displayed. However, costs are exceedingly high due to the expansive material requirements. Photographers seeking the ultimate in print magnitude and resolution will find the classic "three by four" aspect ratio of 30" x 40" ideal for displaying their best work in museum-scale fine art output.
