A 4x6 is perfect for printing out small family photos that you want to keep or share with relatives - whether it's a framed picture on the wall or a print slipped into an album. When people ask "how big is a photo 4x6" - well the answer is a pretty straightforward 4 inches by 6 inches - big enough to show the faces clearly but not so big that it takes up all your wall space. Looking at some online guides on Visuals Clipping will give you a better idea of how to choose the right size photos for group shots and avoid any issues with cropping. Basically, 4x6 is a great size for everyday family portraits and is perfect for adding to your memory collections.
