The first step is to determine the image aspect ratio factor.
Simply divide the larger number by the smaller number to get a factor.
Example – 3888 divided by 2592 = 1.5 (image aspect ratio factor)

The next step is to consider a size you may want for either the short side
or long side of the photo.

If using the photo short side considering a size of 20 inches, just multiply this 20 inches
by the aspect ratio factor to determine the long side dimension.

If using the photo long side considering a size of 30 inches, just divide this 30 inches
by the aspect ratio factor to determine the short side dimension.

Examples of determining print sizes:

Example one:
+++Digital photo pixel dimensions – 3888 x 2592
+++3888 divided by 2592 – Aspect ratio factor = 1.5
+++Considering a photo short side of 22 inches
+++22 inches multiplied by 1.5 = 33 inches
+++Overall print size = 22 inches x 33 inches

+++Considering a photo long side of 45 inches
+++45 inches divided by 1.5 = 30 inches
+++Overall print size = 30 inches x 45 inches

Example two:
+++Digital photo pixel dimensions – 2816 x 2112
+++2816 divided by 2112 – Aspect ratio factor = 1.3333
+++Considering a photo short side of 18 inches
+++18 inches multiplied by 1.3333 = 24 inches (rounded to even dimension)
+++Overall print size = 18 inches x 24 inches

+++Considering a photo long side of 40 inches
+++40 inches divided by 1.3333 = 30 inches (rounded to even dimension)
+++Overall print size = 30 inches x 40 inches

Example three:
+++Digital photo pixel dimensions – 3648 x 2046
+++3648 divided by 2046 – Aspect ratio factor = 1.783
+++Considering a photo short side of 28 inches
+++28 inches multiplied by 1.783 = 50 inches (rounded to even dimension)
+++Overal print size = 28 inches x 50 inches

+++Considering a photo long side of 32 inches
+++32 inches divided by 1.783 = 18 inches (rounded to even dimension)
+++Overall print size = 18 inches x 32 inches

With this simple method of determining print sizes for photo enlargements
using only the pixel dimensions of a digital photo, you can see what the
best prints sizes would be for your digital photos before selecting a size to order.
