Aspect ratio refers to the ratio of the short side of an image compared to the long side.
The aspect ratio of most digital SLR cameras is 2x3 (or 1:1.15 - meaning that the longer side of the image is 1.5 times the length of the short side). This ratio is inherited from 35mm film, which measures 24mm x 36mm (which translates to 1x1.5 or 2x3), though some cameras will have a 3:4 ratio.
So, what does this mean if you want to print a photo taken in the 2x3 aspect ratio?
If you want to print the image at full frame (with no cropping), you can print a size with a corresponding aspect ratio. Larger sizes in this aspect ratio are 8x12, 10x15, 12x18, 16x24, 20x30.
If you want to make another sized print - for example, an A4 print, or a 5x7, 8x10, or 11x14 print, you may need to crop the original image to fit the aspect ratio of your print size, or print with uneven borders.
Printing with uneven borders isn’t a biggie - if you’re planning to frame your print, you can always have a custom mat cut which will allow you to frame your image eve if the frame aspect ratio is different to that of the print.
We can also print at any custom size if you’d like to throw convention to the wind!
