Digital File Size Requirements

Ensuring your digital files are sized accordingly are key to getting a beautiful photograph. If you have a low res file, you will see digital artifacts and pixelation in the print.  In order to know whether your image file is large enough, here are a couple tips.

  • The over-all size of the image is an indicator. If it is over 2mb, that is a good start. However, don’t let that deter you, many times a file will be extra large in size at a lower resolution, often showing a lower file size in your browser.  However, if you see a 4KB file, that is rather small and most likely will not produce a perfect image.
  • If your image viewing application allows you to look at the image dimensions and size, make certain that your file is at least 300 dpi (that is, “dots per inch”) at the image size you would like to print. For head shots,  you would want the file size to 8″x10″ at 300dpi.

The smaller dimensions of a 4×6 or 5×7 might allow for using a smaller image file, but we always recommend you obtain the largest file possible, to make sure that you get the best image quality you can. Sizing down in a photo application is common, however sizing UP is not advised. When you take a small, low res file and change the image size to a larger size, you may be altering the new “size” of the file, however the pixelation will still be apparent.

Tiff and Jpg files are most common, however we also work with raw files such as CR2. NEF, DNG, etc…
