The Panoramic 3:1 print format has dimensions of three times as wide as it is tall. Common sizes are 16 inches wide by 5 inches tall or 406mm x 127mm, giving it an ultrawide aspect ratio. While slightly less wide than 2:1, the 3:1 ratio remains a super-expanded panoramic format compared to 16:9. Its origins trace back to both panoramic film cameras and cropping standard prints to this shape. Today, 3:1 continues to be popular for capturing and printing extra-wide landscapes and sweeping scenes that benefit from the wide dimensions. Typical applications like nature and architecture gain an enhanced sense of breadth and scope from the 3:1 format versus more common panoramic ratios. Printed ultra-wide photos take on an immersive, cinematic feel. While more expensive than standard sizes, the 3:1 ratio grants photographers the ability to realize dramatic panoramic visions with heightened width.
