3. All you really need is the pixels in width and height.

So if you have an image that is 800 pixels wide by 1200 high, and you are going to make a 10 inch wide print, all you need to do to calculate the final DPI (dots per inch) is divide (800 pixels) by (10 inches) and your final print will be 80 pixels/inch. You can use dots and pixels interchangeably.

I'd be really shocked if you really need 300 or higher, I'll bet 150 would be just fine for 99.9% of the population of eyeballs of humans.
