To display your images to fit the Facebook layout, the pixel size of the displayed image areas (width x height) needs to match the allotted spaces in the Facebook template.
For example the Facebook "cover photo" must be 851 x 315 pixels to fit the display area. That's an aspect ratio of 2.7:1. the problem here is most digital cameras save pictures with an aspect ratio of 3:2
To display the image with more detail you can double the size of the image to 1701 pixels x 630 pixels Facebook will automatically downsize the image to fit.
Cropping an image for the Cover Page
Not only did the image need to be cropped, it needed to be "squeezed to fit the Facebook "window"
In Photoshop I used The Menu Item: Edit > Content-Aware Fill and shrank the photo to fit the Facebook aspect ratio of 2.7 to 1 for the cover photo.

Preparing images for Print
After soft proofing...You need to consider these two things
1. Crop to fit the aspect ratio of the paper
2. "Up rez" to enlarge an image to print at a specific size.
Most Epson printers print at to 360 ppi, 720 ppi and 1400 PPI
Most Canon Printers print at 300 ppi. 600 ppi and 1200 ppi
How to setup the correct PPI for a printer "Uprez" in Lightroom (and Photoshop*)
In the Printing Module’s Print Job Panel, uncheck Print Resolution. You should see the native ppi of the print, at the top left of the print display if you don’t see the @ xxx ppi, you need to turn on “Dimensions” in the Print Module.
Menu: View > Guides > Dimensions Keyboard shortcut
"Shift + (Command Mac - Control PC) + U"
To force Lightroom to "UP Rez" the image Check the Print Resolution box
and enter the optimum Printer Resolution in the“Print Resolution Box” Lightroom will “resize the image to match the printers resolution”
Note: if you don’t do this the printer will do the size matching calculations and the result is not as good as Lightroom’s results!
Enter one of the following...
If Image ppi is less than 360 up-sample Epson to 360 ppi
If Image ppi is less than 300 upsample Canon to 300 ppi
If image ppi is less than 720 but bigger than 360 upsample Epson to 720 ppi
If image ppi is less than 600 but bigger than 300 upsample Canon to 600 ppi
* Printing from Photoshop can be difficult, luckily Lightroom's Print Module is way easier to use!
The alternative is to send your image printing to a Printing Company
