If you are exporting photos for web or screen display, you will need around 75ppi (pixels per inch), for home printers 140 – 200 ppi, and the best quality prints will require 300 ppi.Īs a rule of thumb, the number of pixels required for exporting a photo is determined by multiplying the horizontal and vertical print sizes in inches by the pixels per inch. When determining how many pixels you need, it all depends on how you will be using the photo and what size it will be printed. 300ppi is generally considered the point of diminishing returns when it comes to ink jet printing of digital photos. The higher the ppi value, the better quality print you will get. Resolution of an image is measured by pixels per inch or ppi. The more pixels in a picture, the bigger the image becomes. First of all, we will have to relate image size (pixels) and resolution (pixels per inch, ppi).Ī digital photo is made up of millions of tiny dots called pixels.
