What Is A “Social Media Sized Image”

Well…we just made up the term so I guess we can also define it. This is a picture with a pixel dimension and a level of compression that allows for fast uploading to various social media sites such as Facebook, Flickr and Twitter.  They are also small enough to easily e-mail to friends and family.  How large they appear on your screen is dependent on where you have your screen resolution set but they will fill one fifth to one third of your average screen.  The pixel dimension for a image with a 2:3 aspect ratio (same as most 35mm film frames) is 864 x 576 pixels, for a square picture (126 and many roll films) is 705 x 705 pixels.  While you might be able to squeeze an “acceptable to some” snap shot sized print out of these, they are too small for what would normally be considered enough resolution for this purpose.
