Print Size and File Size Calculator
This calculator will help you work out maximum print sizes you can expect from digital images. It will also work out approximate file sizes for Raw, TIFF and JPEG images. As long as you know the pixel dimensions of your image, the calculator will work out the rest for you. You can use it with digital camera images or other digital images.
You know your image dimensions, but how large can you print it? Use this calculator to work out maximum print sizes for digital images printed at 300 dots per inch. It will also work out the file size for each image and let you know how many megapixels the image is. Note: 1 megapixel = 1 million pixels.
All you need to have handy are the pixel dimensions of the image.
