How Many Pixels Does It Take To ...

Ever wonder how many Mega-Pixels it would take to print a larger photo than a 4x6 or 5x7? Well it really depends on how tight you want the printed pixels, or dots, represented in Dots Per Inch (DPI). Say you wanted to print an 11x14 photo at 150 DPI: You would multiply 11x150= 1650 (pixels) and 14x150=2100 pixels which becomes (1650x2100=3,465,000) or 3.5 Mega Pixels. Now if you wanted a really detailed photo you might want to print it out at 200 DPI. So the same 11x14 photo would be 11x200=2200 (pixels) and 14x600=2800 (pixels) which is (2200*2800=6,160,000) or roughly 7 Mega Pixels.
