| First let me preface all this by saying…
You don’t really need to know all this. We’ll take care of it for you.
This is just if you’re curious or very particular. All you really need to know is… If you have a professional uncropped photo, it probably won’t get cropped unless you select the “Bleed” or “Strip” border style. Then, you will lose about two inches. Look at the photos below for an example.
But now, for the curious and particular….
Aspect Ratio is a measurement of a photograph’s width to height. 35 mm film and professional digital cameras have an aspect ratio of 3:2.
To calculate what sizes you can make from this aspect ratio, multiply both the width and height by another number:
3 x 2 = 6, and 2 x 2 = 4, so you can get a 6 x 4 print without cropping.
3 x 3 = 9, and 2 x 3 = 6, so " 9 x 6 "
3 x 4 = 12, and 2 x 4 = 8, so " 12 x 8 "
If you attempt to print photos that don’t conform to the film’s aspect ratio, you have to either pad the picture’s edges by adding a border, or crop the photo’s top and/or sides
Most of our borders are for images with this 3:2 aspect ratio. If you have a standard 3:2 photo, nothing will get cropped.
If you have already cropped the photo to a different shape, or if its native aspect ratio is different (consumer digital cameras have a ratio of 4:3), then it will be cropped to fit these borders.
Bleed and strip borders are for 8x10 images, i.e., images with an aspect ratio of 5:4. This means that if you have a standard 3:2 photo, it will be cropped. (3:2 photos make 8x12 prints, so you’re going to lose two inches.)
To check your aspect ratio.
Windows: Open up the folder where your JPEG file is saved, then move your mouse over the file icon. A window will pop up with dimension information.
Macs: Highlight the JPEG in the finder, click on “File” in the menu bar, and then click “Get Info.” The Info Box will appear, and the dimensions are under “More Info.”
Divide the larger dimension number by the smaller dimension number. If it equals 1.5 (the same as 3 divided by 2), then it’s a 3:2 ratio. If it’s 1.25 (the same as 5 divided by 4), then it’s a 5:4 ratio.
