Aspect and Printing Sizes
I am still a bit confused as to how to utilize an aspect ratio to get an uncropped image printed to normal sizes. I searched around and found a conversion chart. I want to get some 11x14 prints and the chart wants me to multiply the short side by 1.27. What it doesn't explain is am I to multiply the number of pixels on the short side by 1.27? Do I then take the new short side number and the unchanged long side number and plug it into my aspect tool in LR and it will then give me my crop borders?
Aspect Ratio/Print Size/Cropping...

My usual method is to open the Image Size dialog, resize it WITHOUT RESAMPLING as large as it will fit within my desired bounds (e.g. set the width to 11" -- if the height goes above 14", then just change the height back to 14" and your width will decrease proportionally). Accept the changes, then open Canvas Size, leave your Anchor in the center, uncheck Relative, and change the Width or Height till you have your desired size. Hope this makes sense.
Another way is to simply use the Crop tool set to the desired final size. Select as much as you can (it will constrain to the image boundaries at first), then grab and drag the handles outside of the canvas until you have all of the image within the frame.

Let's say you want an 11x14.
11x1.27 = 13.97 (call it 14).
So, if you have an image that is 2000px on the short side (like something like 3000x2000 if youre taking an image straight from the camera), then you'll want to crop it to:
2000 x 1.27 = 2540px
So you'd have an image that is 2000x2540.
Strictly speaking, an 11x14 is a 1.2727272727 (etc) ratio. So, 2000 on the short side means 2545.4545 (etc).
It'd be slightly more accurate to make your crop 2000x2550. That's about as close as youre gonna get.
The same technique applies to any other ratio. To figure it out:
Long side measurement (inches) / short side measurement (inches) = ratio
Ratio * short-side measurement (pixels) = Long-side measurement (pixels)
Print size = Short side measurement X Long side measurement
