Look at the EXIF data. Pixel dimension divided by the "ppi"indicates what the physical size would be at 100% magnification. E.g., 3000x4500 would yield 10x15 inches at 100%.

Thanks. I appreciate your dilemma and his also. Goes to prove that sometimes, yes sometimes you cannot have your cake and eat it to. His wise decision would have been to make a frame for the 8x12 but I guess that is asking too much.

The 35 mm is the physical width of the film. Images thereon are 36 mm x 24 mm. The shape ratio is 3:2 so any final print or display at that ratio is a simple enlargement. Prints or displays at any other shape ratio must be 'cropped' in some way. Some dumb displays show what is there and may have to 'scrunch' the dimensions, yielding weird results.

Actually in the end while he didn't like the result he became a good customer. I guess because my effort to try to make him happy.

Without losing any image, you can do a 6.66X 10 image on an 8X10 sheet .....from full frame 24X36mm film image.

Darn. I was hoping for a softball question: what is 2+2?

Any print size with 3:2 aspect ratio allows for full frame of MOST 35mm film images to be printed without any cropping. The vast majority of that type of camera makes a 24x36mm image.

4x6, 6x9, 8x12, 10x15, 12x18, 14x21, 16x24, 18x27, 20x30, 22x33, 24x36, 26x39, 28x42, etc. are all print sizes with precise 3:2 aspect ratio.

There were SOME 35mm roll film cameras that didn't conform to the standard 3:2 aspect ratio. For example, in my collection I have some post-WWII non-interchangeable viewfinder cameras that were designed to make 30x36mm images on a special type of 35mm roll film that doesn't have the sprocket holes along the edges. There also have been "half frame" cameras using 35mm roll film that in a few cases produced unusual sizes (although among half frame the vast majority are also 3:2 aspect ratio).

There is a diagram of the 35 mm standard on page 24 of the free book available at:

Yes, but they had to be cropped. As you stated later, a 35mm is 24x36 mm. That is a 2x3 ratio, thus your photo had to have two inches cropped from the long side to give you an 8x10 since the blown up size would have been 8x12 before cropping.

Paulrph1,
You need to print in 8x12 in landscape mode to preserve the aspect ratio of 3:2 with the least white space.
