To find the resolution, or DPI, of an image, you'll need to know the width in both pixels and inches. Divide the pixel dimensions by the dimensions in inches. For example, an image that's 1000 pixels wide and also 13.89 inches wide is 72 DPI.

Similarly one may ask, what size is 300 dpi in pixels?
1 inch = 300 pixels, so a 4” x 6” image requires 1200 x 1800 px to print at 300 dpi.
One may also ask, what is 72 dpi in pixels? Pixel density Now, the resolution is expressed in dpi (or ppi), which is the acronym for dots (or pixels) per inch. So, if you see 72 dpi it means that the image will have 72 pixels per inch; if you see 300 dpi means 300 pixels per inch, and so on.
Correspondingly, what does 600 dpi equal in pixels?
Since a 600 dpi printer can print 600 dots both horizontally and vertically per inch, it actually prints 360,000 (600 x 600) dots per square inch. Also, since most monitors have a native resolution of 72 or 96 pixels per inch, they cannot display a 300 dpi image in actual size.
What resolution is 72 dpi?

- Take the value in the "Width (mm)" column and divide it by the width in pixels. This is called "pixel size x".
- Take the value in the "Height (mm)" column and divide it by the height in pixels. This is called "pixel size y".
- Calculate the average between the two values - ("pixel size x" + "pixel size y") / 2.
