Resolution Calculator answers the question "how big can I print this?". Enter a picture's width and height in pixels to see its print size at each common DPI, along with its megapixels and aspect ratio. As a rough guide, 300 DPI looks sharp in your hand, while large posters seen from afar can use less.
