Figuring out what size your image will print

Figuring out what size your image will print is just a bit of math

number of pixels divided by dpi equals inches
720 ÷ 200 = 3.6

Here is a chart of some common sizes showing what happens when an image is created based on looking at dpi and inches, rather than pixels.

If your image is                            
dpi and it is inches wide by inches high then it is pixels wide by pixels high and at dpi it will print inches wide by inches high

*pixels have been rounded to the nearest pixel because you can't print a partial pixel.
