18x24 is one of our most popular frame sizes. With the same 4:3 aspect ratio of many modern digital cameras, an 18x24 frame works great for digital prints. A 12x18 print fits in with a 3 inch mat margin and a 13x19 with a 2.5 inch mat margin. 11x17, a very common size these days for event posters, playbills and digital prints with a white margin, is a perfect fit with a 3.5 in mat border. Frame Recipe: Take a 12x18 black and white digital print and combine it with a 18x24 Cut Mat; and an 18x24 black Colorful Contemporary Frame for a classic gallery look. A typical 18x24 frame will cover 1/4 inch of your image all around, resulting in a view window of 17.5x23.5. If you would like a mat to complement your frame, visit our 18x24 Cut Mats. With a mat, a 18x24 frame works best for artwork from 9x15 to 14x20.
