A0, A1, A2, A3, A4 aspect ratio is the main reason behind the magic of an A size poster. A4, A3, A2, A1 and A0 are actually extremely clever sizes. They have been thought out in a very unique way. Two A4s laid side by side will fit into an A3, two A3s laid side by side will make an A2 and so on … up to A0. This is actually a very clever concept, which has been created using a very magical aspect ratio (1.414:1). This has set an amazing international standard, which today we accept as perfectly normal, never questioning the unique way the sizes fit into each other.
All A size posters retain exactly the same aspect ratio, regardless of whether you are printing a large A0 poster or a standard A4 print. The advantage to photography is the ability to purchase an array of ready-made frames that your image can slot into. Fortunately, the photos taken on most of todays devices – cameras, phones or tablets can easily be cropped to fit, with very little lost from the original image.
