Digital Image Storage Table
 

A digital image’s file size is mostly determined by the digital image’s resolution and the digital image format. Other factors that can influence the file size, depending on the chosen digital image format, is the number of colour channels per pixel, compression level, the digital camera’s settings and the complexity of the scene being photographed. The last three factors are applying only when using the JPEG format. The most important rule to remember is that higher image resolution, more megapixel, leads to larger file size.

Determining an image’s file size in advance for the TIFF and RAW format is relatively easy. But doing that for a JPEG image is impossible. It is also impossible to have the some file size for all images since each image is unique when shooting in JPEG mode. Therefore in our table below we assume that all JPEG images have the same file size.

The methods that have been used for the above calculations can be found at TIFF, RAW, JPEG. The above MB and GB definitions may be misleading since the exact amount of bytes is not exactly what the terms are indicating. The correct conversions can be found at byte. It is important to have in mind that approximately 6 % of a memory card's listed capacity is used for memory management, and therefore is not be available for data storage. This has been taken in consideration in the above calculations.

A table over the number of songs, music minutes and the number of CDs that each memory card capacity can hold can be found at digital audio storage table. Also a table over the number of video minutes that each memory card capacity can hold can be found at digital video storage table.
