File size is the ultimate limiting factor when you work with picture files. File size is the most common cause of problems when you work with pictures in Microsoft Office. File size is determined by the following factors: picture size, resolution, file format, compression, and color depth.

The file size is just that. How large the file is measured in bytes, kilobytes and megabytes.

The length of a file, typically given in bytes. A computer file stored on disk actually has two file sizes, logical size and physical size. The logical file size corresponds to the file's actual size—the number of bytes it contains. The physical size refers to the amount of storage space allotted to the file on disk. Because space is set aside for a file in blocks of bytes, the last characters in the file might not completely fill the block (allocation unit) reserved for them. When this happens, the physical size is larger than the logical size of the file.

number of bytes of memory making up a file. Most search engines limit banner sizes to between 8k and 15k

The total number of electronic pixels needed to create a digital image, measured in kilobytes. The more pixels an image uses, the more detail it will contain.

The amount of disk space that an image takes up

The disc space required to store a digital file - measured in bytes, kilobytes, megabytes or gigabytes.

the size of an image in digital photography, measured in kilobytes (KB), megabytes (MB), or gigabytes (GB). File size is proportional to its pixel dimensions; images with more pixels may produce more detail at a given printed size, but they require more disk space to store and are slower to print.

the total amount of digital image information in a digital file. The formula to determine file size is length x width x resolution(ppi) x resolution(ppi) x3(RGB color) all divided by 1 million. e.g. You need to produce an 8x10 at 300dpi. So, 8x10x300x300x3 divided by 1 million = 21.6mb file needed.

the total number of bytes in an image. Size is determined by file format, colour depth, image size, resolution, and editing effects (such as “sharpening”).

Number of bytes of computer memory comprising a file.

Sometimes used interchangeably with resolution or pixel dimensions to indicate the quality of an image.

is the product of DPI-squared multiplied by tonal resolution (2"x2" at 72 dpi = 144 x 144 = 20736 = 20K bytes for 8bit image (Web) (5" x 5" at 200 dpi = 25 x 40000 = 1000000 pixels: = 1 MB for 8-bit color, or 3 MB for 24-bit color) (8" x 10" at 300 dpi = 80 x 90000 = 72 00000 = 72 MB)

The actual size of the file. When referring to online banner advertising, this is the actul size of the image file in kilobytes.

The size of a file measured in kilobytes (KBs). It is important to know the size of the files you include in your site, as large files can affect the time it takes for your visitors to load a page. You can view file size details from the Site Manager.

The amount of disk space that a file requires for its existence, usually measured in bytes.

The size of the file is the amount of disk storage space taken up taken up by a file (measured in bytes). Generally, smaller files will load (appear on the screen) faster on the World Wide Web, and it is to your advantage to make files as small as possible.

For migration prioritization purposes, the size of a file in 1-KB blocks.
