  • File size measures the size of a computer file.
  • File sizes can be measured in bytes (B), kilobytes (KB), megabytes (MB), gigabytes (GB), terabytes (TB), and beyond.

File size


To calculate a file size


    • File size is determined by the number of pixels. Since the resolution is 300 dpi, it means that each inch is 300 pixels across.
    • As the image is 8 inches wide that means there are 2,400 pixels in width (8 x 300) & 12 inches long, the image is 3,600 pixels in length (12 x 300).Total pixel (2400x3600) is 8,640,000.
    • The file size of 8,640,000 bytes or about 8.2 MB (this is because there are 1024 bytes in a kilobyte and 1024 kilobytes in a MB).
