A 4x6 is not the same sort of size as most social media images which usually need to be square or vertical. So when someone asks "how big is a photo 4x6" and compares it to online images - well it's still 4x6 inches physically, but you may need to crop it to make it fit on social media. Visuals Clipping has some pretty simple guides on cropping your 4x6 images so you can use them on things like Instagram and Facebook without losing any of the important bits. This makes sharing your printed memories online a whole lot easier and more consistent.
